What's the purpose? For that wheel size, something in the realm of 205/45/16 or 215/40/16 would be good. 225 is a bit wide for my tastes, I have a whole set of 225/45/16 Kumho MXs sitting my warehouse because I hated the way they handled. I might put them on my Prelude for daily driving tires, but that's about it.

 

well hankook has a 225-40-16 RS2 that is really stiff I know a bunch of my miata buddies use those for street and roadracing

 

Yes, what's the purpose? Because if you're doing it for performance, no 225/40-16 street tire is going to grip as well as the Falken Azenis RT-615 in 215/45-16. And the Azenis is a better fit for the ITR anyway, since the outer diameter in that size is closer to stock (within 1 percent).

 

Car felt awesome with 225/45/15 Hankook RS-2s on the track yesterday morning...

The RT-615 is even better. Not just my opinion, but also that of Grassroots Motorsports. (Remember, performance differences for different models of tires are nearly always much, MUCH larger than differences due to 10 mm of treadwidth.)

Also, it's kind of hard to mount those 225/45-15 tires on 16" wheels...

 

Well yeah, was just a reply to the 225 width more then anything.

Ken, does Falken make the RT-615 in 225/45/15?

 

FWIW, I've currently got 225/45/16 on my 16x7 +50 wheels, they fit fine. I will probably switch back to a 215/45/16 the next time I buy tires though...

No.

BTW, to see how all of these sizes compare in diameter with the stock tires:

195/55-15: 23.44 inches (stock)
205/50-15: 23.07 inches (-1.6 percent)
225/45-15: 22.97 inches (-2.0 percent)
215/40-16: 22.77 inches (-2.9 percent)
225/40-16: 23.09 inches (-1.5 percent)
205/45-16: 23.26 inches (-0.8 percent)
215/45-16: 23.62 inches (+0.7 percent)

 

225/40/16 kumho tires on wifey's itr are

not as grippy as the azenis, but this is a daily and the rain traction more than makes up for that.

ill have to second that what im runnign right now and they dont grip that good but just for the daily grind work great

 

I think 225/40-16 is just a bad size for daily driver use on the ITR. Especially if you care about traction in rain, where wider is worse. There are a lot of excellent tires available in 205/45-16, including the Goodyear F1 GS-D3 (one of the best tires out there) and Kumho SPT (at $75, great "bang for the buck"). Both of these are very good indeed on dry pavement and absolutely awesome in rain, and last quite a long time (typically 25-40K miles, vs 10-12K for the Azenis and 15-18K for the Hankook).

Of course, if you're shooting for the "low rider" look, with the extra width and the smaller diameter, they can give that to you...

 

Damn, I really like the size of this tire in all aspects...

that is exactly why we got them. the wider tire is better in the dry, whereas the tread pattern is exceptional in the wet. the compound is quite long lasting as well, and the shorter sidewall adds responsiveness. overall, it is a very nice compromise - especially for a commuter. I don't mess with expensive street tires anymore - save the r compounds for the track.

I disagree completely!

Ken - do you have personal experience using this tire size to make this statement?

I have been using 225/40-16 in on my R for about 4 years now and have NEVER had an issue with poor wet weather traction.

It rains quite a bit in Vancouver - and I have a lot of track day experience in the rain.

Besides the contact patch of a 215/45 and 225/45 are virtually the same.

Tire construction, tread design and compound hardness are likely to make much bigger differences.

 

So what tires are you guys getting in 225/40-16, anyway? Because you don't have many good choices in that size, and the few choices are neither the best performers nor the best value. The only tires I know of that come in that size are (a) the Falken Ziex ZE-512, which is an absolutely crappy all-season tire; if you need all-seasons (because you need to use the same tires on snow in winter as well as in moderate to warm temperatures the rest of the year), you can get the Kumho SPT in 205/45-16 and it will give you WAY better traction all the time, hot, cold, wet, dry, snow, than the crappy ZE-512; or (b) the Toyo T1-R, which is a decent summer tire but really not any better than say the Kumho SPT or Yokohama ES100, both of which are available in 205/45-16 for a whole lot less money than the Toyo. The SPT, in particular, is awesome in rain, MUCH better than the T1-R. So is the Goodyear F1 GS-D3, also in 205/45-16, which is a bit more money than the T1-R but is a way better tire in dry weather as well as in rain.

 

thanks to all the answers but im not in need of what tires i should run or not thats not my question.
i have ONE purpose with this operation and that is to get better grip with my R on the track nothing more nothing less. for all of you who cares im going to run on toyo R888, best bang for the bucks here in sweden.

so back to the question, do I need to make any modifications on my R to get the 7.5" wheels to fit? what have you done Big Phat R to make it fit?

cheers once again

I don't know whether that offset will work without rubbing, etc.

The width is rather narrow for the tire size. I know the T1-R in 225/40-16 is approved for mounting on rims 7.5-9.0 inches wide, and I can only guess that the R888 is the same. (The R888 has only recently been introduced in the States and isn't available in 16" sizes, so I can't look up the specs.) Since 17x7.5 is at the very low end of the approved range, you could mount them, but they'll be pretty wide, bulging out. A 17x8 or 17x8.5 would probably be better (for handling as well as looks).

Again, for street tires, I think you're much better off in every way with 205/45-16 or 215/45-16. R compound track tires like the R888, though, depend on availability. I know there are a lot more track tires available for our cars in 205/50-15 than in 16" sizes.

 

225/40-16 on a 16x7 +50mm offset fit the Type R with no modifications whatsoever.

No rubbing either.

 

sell me your wing

 

that is looking great man!!!! those rims aaah could die for them

the thing is that im going to use racetires, dont know what you call them in the usa but we say R-tires...as you might know they are a bit higher and wider than normal tires, do you think that if I press the fender flares will make it or do you have a lot of space left? i seems that you have pretty much to go on

thanks for the Rocking pics

In the States, we call them "R compound" tires. Toyo RA-1 or R888, Yokohama A048, Michelin Pilot Sport Cup, Pirelli PZero Corsa, Hoosier R6, Hankook Z211 and Z214, Kumho Ecsta V710 and V700 Victoracer, BFG g-Force R1, etc.

 

Sweet looking R

 

yes i know that you just got them to the states r888. its a real jdm tire for good money so easy choice for most of ous here in sweden that got use for R tires as for a048 they cost something around $300 each, if you compare that to toyo that cost $115 you make the choice

 

In case you're interested, here are U.S. prices of R comps in 205/50-15 (prices are from Tire Rack except where indicated, and do not include shipping, heat cycling, or shaving):

Hankook Z211 $95 (Frisby, closeout special)
