... at least in Hawaii it is. What other tire size would fit the JDM ITR 16's? I saw some suggestions on HT for 205/45R16 but the the original tire size already seems narrow for the rim. would it function and look the same with 215/40R16 or 205/50R16?

 

215/45-16 is an "oddball" size with few offerings. The Falken Azenis RT-615 comes in that size; if you want a tire that is supersticky on dry roads and you don't mind the fast treadwear or the so-so wet traction, that's an excellent choice. The Dunlop Direzza DZ101 is also available in this size; it's similar to the Yokohama ES100, with pretty good dry traction, excellent wet traction, and very good treadlife.

For other tires, get 205/45-16, which will work just fine on those rims on an ITR. (Don't get 215/40, which is too small in diameter, or 205/50, which is too large.)

 

Im pretty familiar with the few tires available in the 215/45 size however NOBODY here has them. shipping is a bitch!

 

As nsxtasy already stated, 205/45-16 will work fine, and will have a larger selection from which to choose.

 

Have you tried these dealers? Can't they get them?

No kidding! I just checked Vulcan's website, and it would cost $194 to ship a set of 215/45-16 Azenis to you!

 

I've called several of the larger tire locations and they got nothing in stock in that size.

Even the dealers in Ohio (Discount tire, etc) don't carry the Azenis RT615's in stock. I always have to have them order them.

 

205/45/16 = 23.3" diameter
195/55/15 = 23.4" diameter
215/45/16 = 23.6" diameter

So 205/45/16's are closer in size to the stock ITR tyre. I too couldnt find a good 215/45/16 tyre at a reasonable price, and i didnt want Federal tyres ($78 each) so I opted for 205/45/16 Toyo T1R's at $85 each.

IMO the extra width more than makes up for the slight gearing hit.

The 215/45/16 is the JDM OEM size, and it's worth finding the size if you can.

I have used 205/50-16 Goodyear Eagle F1 GS-D3 without any clearance issues at all, this on 16x7 +42 wheels and stock suspension. They are a bit taller than stock, but only 2.7% or so, not too big as far as I'm concerned. I have also used same tire in 205/45-16, and that one is a bit too small, I preferred the 205/50 over that one.

 

Just put 205 45 16 yesterday on my ITR JDM rims.. no problems... looks good. Got them at http://www.tirerack.com

Even on the mainland, most tire dealers don't stock higher performance tires, but can order them. Did you ask them if they can order them for you?

Actually, if you do the math without rounding, you'll find that the difference from the stock outer diamer is almost exactly the same for the two sizes; 205/45-16 is 0.18 inch (0.77 percent) smaller than stock, and 215/45-16 is 0.17 inch (0.74 percent) larger than stock. Both are within 1 percent and either one will work fine on our cars.

Most good tires come in either 215/45-16 or 205/45-16, but not both. Decide on the tires you want, and see which size they come in. If you are looking only for the best traction on dry pavement and you don't care about value (treadlife/price) or wet traction, get the Falken Azenis RT-615, which comes in 215/45-16, costs $95 each, and typically lasts 10-12K miles. If you are looking for good performance but you also care about value, I think you're better off with the Kumho Ecsta SPT than the Toyo T1-R (again, 205/45-16). Performance is similar - both offer pretty good dry traction, wet traction, and treadlife (30-40K), but the SPT is only $54/tire after the $40 rebate.

I disagree.

The biggest factor between tires is the tire model, not the tire width. A stickier tire in a slightly narrower size will always give better performance than a less sticky tire in a slightly wider size. So if you're looking for performance, you should concentrate on getting better tires, not wider tires.

The Falken Azenis RT-615 in 215/45-16 is the stickiest 16" street tire you can get for the ITR. That's NOT because it's 10 mm wider than 205/45 tires (and NOT because it tends to be slightly larger than other tires labeled at the same size), but because of its design, with its soft tread compound, large tread blocks, etc. The Azenis is also stickier than tires that are wider; for example, in 15" sizes, the 205/50-15 RT-615 is a whole lot stickier than the BFG g-Force Sport in 215/50-15, because the RT-615 is a sticky tire and the BFG is not.

There's absolutely NO reason to get oversized tires like 205/50. They offer no performance advantages over 205/45, and several disadvantages (greater weight, slower acceleration, more sidewall flex). 2.7 percent is a big difference!

The F1 GS-D3 is another terrific tire - a bit expensive, but with outstanding performance on both dry and wet pavement (better than the Toyo T1-R or Kumho SPT) and it lasts a long time (25-35K miles). It's available in 205/45-16 ($123/tire after $40 rebate). And on a cost-per-mile basis, taking treadlife into account, it's actually less expensive over time than the Falken Azenis RT-615.

I think Todd is speaking of his specific experience using different sizes of the same make wheel. For example, 205-50-15 RA1 vs 225-50-15 RA1, or something similar.

If you each had to make a specific recommendation for this particular poster, I think you'd both say the same size and brand.

It's great that Falken continues to cater to a small, specific enthusiast base of Honda/Acura users by continuing to market the RT615 in 215-45-16, and at an attractive price. We'd probably all agree that it's a no brainer for a warm weather street performance tyre.

The OP's situation got complicated because he had a hard time finding these in Hawaii. Or at least he had a hard time finding them cheaply.

For street tires - and we're talking about street tires - there is an overemphasis on tread width, and it really doesn't matter. Put a driver in two identical cars with identical street tires (same tread depth) except for a 10 mm difference in treadwidth, and you won't be able to tell the difference between the two, even driving them back to back.

Again, it sounds like he is only looking for tires in stock, which is a mistake IMHO. I doubt that you could find them in stock at most tire dealers in most places in the country, unless you happen to live near the Tire Rack or a place that specializes in high-performance tires, which are few and far between. Yes, shipping costs are higher - that's a trade-off of living in Hawaii - but I would assume that dealers there can order tires for you, just like dealers here can.

Yes, exactly what I'm talking about. We all know tire compound is the first and foremost requirement for a tire being good performing.

As for telling a difference between a 205 and a 215, remember you are adding an extra 40mm overall of treadwidth. That will translate into more grip.

The only time that treadwidth is too much is when you don't match it to a properly sized wheel. For instance, a non R comp. tire in a 225 size won't perform as well on a 6.5" rim as a 205 will on the same rim. Most of this is due to street tires having a rather soft sidewall. Response time is often a significant factor in a good handling car...not just overall grip.

 

For street tires - and we're talking about street tires - there is an overemphasis on tread width, and it really doesn't matter. Put a driver in two identical cars with identical street tires (same tread depth) except for a 10 mm difference in treadwidth, and you won't be able to tell the difference between the two, even driving them back to back. And don't multiply that 10 mm by four tires, that's a transparently phony ploy to make it sound bigger than it really is; everyone knows that 10 mm is 10 mm. And 10 mm doesn't mean more grip if the tires aren't as sticky.

Again: If you want more grip resulting in better performance, concentrate on getting better, stickier tires, rather than wider tires.

</TD></TR></TABLE>

How is 10mm x 4 tires not 40mm more tread?

But if the stickiest tire available comes in both a 205 and 215, then why not get the 215?

And I disagree...take two identical tires and go autox a 205 on a properly sized rim then do the same with a 215 on a properly sized rim. The 215 will be faster.

With the old Azenis 215 on my ITR, I had a 205/50/15 on a 7.5" rim and a 215/45/16 on an 8" rim. I tested both back-to-back and the 215 was faster by at least 0.3 almost every run.

But what tire currently being made is a better and stickier street tire than a 215/45/16 Azenis RT615? Name a 205 or even another 215 (in like diameter) that will outperform it in the dry.

 

Because we don't add up the amount of tread on four tires. No one talks about comparing 820 vs 860 mm of tread! Maybe you also go around saying that the stock ITR has 100 more horsepower than the GS-R because you're comparing four ITRs with four GS-Rs. Technically the numbers are true, but it's misleading B.S. because no one cites measurements in those terms, unless they're trying to exaggerate the truth. In my experience, most people start throwing around B.S. numbers because they can't make an argument with real numbers that people normally relate to. Face it - claiming that a 10 mm difference in treadwidth is 40 mm is total B.S., a B.S. way of trying to make the difference in tread seem greater than it is. Most people here don't want B.S. like that, from people who can't make an argument so they resort to B.S. They want good information.

Because it's not. Most tires are available in either 205/45-16 or 215/45-16. Not both. Here is a list of all the tires available from the Tire Rack in both these sizes:

<u>List</u>:
(list is empty)

(The Falken Azenis isn't available from the Tire Rack, but it's not available in 205/45-16, either.)

If you want better traction, get the tire that gives you better traction - regardless of whether it comes in 205/45, or 215/45.

By how much, a few thousandths of a second? Compared with differences as high as a half a second to a full second or more when switching between different kinds of tires?

On the street, there will be NO perceivable difference.

You sound like people who talk about reducing weight by a couple of pounds as though it's going to make a huge difference, when it's not (it's only one hundredth of the difference that reducing 200 pounds will make, which IS significant).

I guess you didn't read my previous post, where I said:

You keep trying to mislead people by referring to what is NOT important. And, compared to most other factors, a 10 mm difference in treadwidth is NOT important.

Seriously nsxtasy...10 more mm of tread per tire is indeed 40 more mm on the car, no matter how to want to talk about it. And 40 more mm of tread is 40 more mm of tread.

That's roughly 1.6 inches more rubber total. It also changes the area of the contact patch. Not the overall area, but the way the tire contacts the ground. And this change is in a positive way for lateral grip.

We can argue tread compound forever but everyone is in agreement on that subject. But if you read my post, you'll see where I included actual testing of tire widths.

If you truly want to know what tire works the best, put down the magazines and go test them on an autox course as that's really the only way because of the mix of variables. I've tested or been around those that have tested every compound available in the last 5 years, and I know what works and what doesn't on Hondas.

I can tell you what tire to use on your EF on certain courses and even what size to use it on. I can say that a 205/50/15 is a faster tire in some circumstances compared to a 215/45/16 on an EF because of the gearing, and sometimes the 215/45/16 will crush the 205 on certain courses.

Seriously, I'm not just spewing and none of my infomation have come out of magazines. They are a good basis of info, but that's about as far as it goes unless you get into the tests by GRM that are more 'lifelike' than the others.

 

Just buy some tires.... who cares. I hate tires, i jsut buy tires with decent overall performance, and good tread life.

Nonsense. That's total B.S. because no one adds together the treadwidth from four different tires. No one talks about 820 mm of treadwidth when they're talking about four tires having 205 mm each. No one - unless it's someone who really has no facts to argue with, and they just try snowing people with B.S. numbers that they make up, numbers that no one else uses. And that's exactly the B.S. you're spewing when you add together the treadwidth from four tires.

Wrong again. Wrong because of the B.S. aspect of adding together dimensions of four different tires. And wrong also because - as you yourself admit - the size of the contact patch doesn't change; 0.4 inch (not 1.6 inches) more rubber in the lateral direction of each tire also means less rubber in the longitudinal direction. So again, you're trying to mislead people with B.S. by stating numbers that nobody uses, while ignoring the REAL numbers that show that your argument is B.S.

And I've tested and driven and ridden with every compound available in the last 20 years - in fact, I bet have at least two, maybe three times as many track miles of experience as you do - and I know what works and what doesn't on Hondas. And the simple fact remains: 10 mm of treadwidth doesn't mean jack.

I can't remember anyone "spewing" a more B.S. number than adding together the treadwidth of four different tires.

BTW, you have a "tell" in your posts - a "tell" the same way some people twitch their noses or have some other mannerism when they're holding a good poker hand. Every time you use the word "seriously", you then say something that's B.S. You make it very obvious when you're trying to snow people. It's pretty funny.

Again: <FONT SIZE="large">If you want more grip resulting in better performance, concentrate on getting better, stickier tires, rather than wider tires.</FONT>

 

Seriously nsxtasy, you won't give up, will you? There are a ton of factors to consider when finding a tire that will handle best. You seem content on yours and that's it.

I seriously don't think judging tires on a roadcourse via an HPDE is that great of a benchmark, but you seem to think its god-like. I think there are much better methods of tire-testing...tests that include all elements of driving situations. HPDE's don't offer that. You can have 300K HPDE miles, but that doesn't really tell you crap other than 'feel'.

And again, you are smoking crack if you don't think 10mm per tire doesn't mean jack. Yeah, a 400 treadwear General in a 215 won't be as good as an Azenis in a 205, but let's be realistic and compare apples to apples.

No one is snowing anyone and your word isn't the final say-so, like you seem to think.

And since when are longitudinal contact patches good for handling? And where are your real numbers? I have real numbers down to the hundredth...do you?

Jesus I'm getting tired of your 'know-it-all' attitude when it comes to street tire choices. The main point of the thread is choose a good compound, AS WE ALL HAVE SAID time and time again. Why you are nit-picking crap is beyond me.

 

You're the one who keeps spewing B.S. and nit-picking. If you don't like the replies you get, pointing out your B.S. and nit-picking, then don't post.

Indeed there are. And handling is not the only factor in choosing a tire.

"Content on mine"? Speak English, please.

There you go again, trying to bring in more B.S. People can read posts and see what is said - and they can see that this statement is simply more B.S. mischaracterization of my posts (no, I never said or implied that) in order to distract from the main point. Most people here can see through B.S. like that.

There is FAR more difference in performance between different tires than between the same tire with 10 mm difference in treadwidth. If you don't understand that, then you either don't have enough experience to recognize it, or else - in your words - "you are smoking crack" (another attempted distraction).

I don't recall a bigger snowjob attempt than adding together the treadwidth of four different tires. Anyone who isn't trying to snow someone would never quote such numbers.

I never said it was. Again, you keep trying to throw out insults in order to distract from the central issue. More B.S. that anyone can see through.

You haven't quoted any real numbers. Other than that B.S. number of adding together treadwidths of four different tires.

Can you quote exact lap times for the same tire with the same tread depth and two different treadwidths that are 10 mm apart?

And I'm tired of your gross ignorance. I've never heard so much B.S. from anyone who knows so little about tires!

I know about tires from trying all of them out at the track and on the street (and yes, in an occasional autocross). I am happy to share my knowledge. I don't claim to "know it all"; tossing out irrelevant insults like that simply another of your B.S. attempts to distract from the real issues.

Agreed. Or, as I stated, If you want more grip resulting in better performance, concentrate on getting better, stickier tires, rather than wider tires.

So why do you keep arguing otherwise?

Why you are nit-picking crap, and tossing around insults and B.S. upon B.S. upon more B.S., is beyond me. If you don't want anyone else to reply, then don't post anything to reply to.
