Got any data to back that up? Not arguing but that seems like a pretty strong statement so I am hopping you have some data to share.

I have 15x7 +30 C1Ms that are getting tires mounted tomorrow. They're going on a Miata though so I don't have any worthwhile info for you guys.

 

I'm running 225/45 RS-3s on my 949 15x8s. +36 offset. I have yet to see a track and really beat the **** out of them but they fit fine with no spacers needed. Great tires for the price.

 

What data is needed? A 205 is the proper width tire for a 7" wide wheel and it fits perfect. Why add another inch to your wheel only to have more weight and more chance of clearance issues? If you don't utilize the benefit of a wider wheel which is wider tires then why do it? If a 205 fit nice on a 6" wide wheel I'd probably run one but they do bulge a little.

 

That they do but they also wear out twice as fast as my RE760's and don't do so well in the wet.

 

I have 225's on my 949 wheels that I use for competition events.

I have no camber kits front or rear on the car, I did have to raise the rear a little ( fender gaps match front and rear now) and remove some shims from the rear UCA (so it currently sits with no shims).

The wheels are for appearance and not competitions as I already have something for that. The fenders are rolled and it will still rub a little, if I were to raise the car a little more or bought a camber kit this could be reduced or prevented but I don't care much, I don't get too crazy on the streets anyhow.

Don't turn this into a tire stretch debate, everyone knows the bullshit about how dangerous it is. If it was so dangerous Tire Rack wouldn't have done it for me and it's obvious the XS runs wide enough for the rim.

 

Lap times would be a good place to start.

The Miata community has shown pretty conclusively that a 225/45 on a 9" wide rim is quicker than the same tire on a 8" wide rim. I suspect the same would be true of a 7" vs. 8" with a 205 but I haven't seen as much data on that subject.

I have 7s right now and I'm going to be running 205s so obviously I don't care too much. I just though that was a pretty bold statement based on what I've heard.

 

Well a 225 is 8.86" and the 205 is 8" so yeah I guess it would make sense. How much difference in lap times are we talking? Maybe I rambled on and bit off more than I can chew too quickly. But this being the case then on a 7" wide wheel a 185 would be better than a 205? Could it be that sidewall flex is what made that possible? I find it hard to believe that a 185 will be faster than a 205 given a rigid sidewall where flex is minimal.

 

I think im going to order their 15x7.5 +42 and 205 star specs for my newly acquired 93 hatch, then at some point go to 225 hoo hoos. I came from a DSM so this stuff is new to me, should I have any issues? Fenders rolled a bit, and I will be running like 6-700# rate springs on the car. Seems as though the sweet spot for 225s is like +36 so I could always run spacers when I go to a 225. Thoughts??

 

JGallamore, I used a set of 15x7 +42 with 205 Z1 Star Specs, They held up fine, unless you plan on going with a 225 or a 215 later down the line the .5 is just added weight!

 

On backorder til the 18th, hopefully I got in on time for this shipment. 15x7.5 +42 with 205 star specs. Tirerack almost refused to ship these to me saying they wouldn't fit the car. Those with these wheels they just require the regular "tuner" style lugs? I'd assume so.

 

i cancelled my order because it was going to take like 2-3 weeks to get them. they are awesome for the price, i picked up some used rpf1s instead.

 

I run 225s on the front of my civic for autocross. 205s in the rear.
All 4 fenders are rolled and the fronts are slightly pulled.

No significant rubbing. Spring rates are 600f 800r, no front sway bar, comptech rear sway bar.


^^ I raised it a little bit after this pic.

This is the height its at now:



Right now, Im in between DDs so Im having to drive my civic everyday *shoots self in head*
Im running 195/50s all the way around at the moment.



I really like these wheels. I had a hook up at tire rack so I got them for $320 shipped to my door.
8" wide, relatively light, and not bad looking. Cant beat it, imo.

 

How did you like auto-crossing the nitto's? They have been my favorite tire so far, currently trying out the Kook 214's but they are a bit different than i am used to.

 

I really like them. Obviously, they aren't as fast as some of the dedicated autox R compounds, but they are a happy medium, imo.
They are cheaper, they last longer, and I usually drive to events on them. So no mounting wheels in the parking lot.

 

can you share some more specs on your setup?

15x8 ___offset (assuming +20's) and 225/45 nt-01's???

thanks

You're looking at this the wrong way. For the same size tire, a wider wheel is faster (up to a point). Regardless of wheel size (up to a point), a wider tire is faster than a narrower tire. For example, D Stock Solo competition limits an ITR to a 6" wheel. Guys will run the 275/35/15 on this 6" wheel because it is a touch faster than the 225/45/15 which is faster than the 205/50/15. The 205/50/15 fits the wheel the best, but the extra tire width makes up for the less than optimal wheel width. In DSP, I run the same front tire but I can support it with a 10.5" wide wheel. My car uses the tire better because of this.

 

I want to order the 15x8+20.. I have 205/50 XS's already.. next alignment will have my camber at -3 front and -2.5 rear.. doesn't seem like that will be a problem from the looks of this thread right? Will be going 225/45 next time around on tires..

 

225's will not clear on the 15x8 +20

 

The purple hatch has 225/45's above and says its not too bad. Eg's have a bit better clearance it seems.

 

Who says 225 wont clear? I was on 15x8 +16 on 225 R888 which are way wider than the street tires that have been posted... Did I mention the fender wasnt rolled

 

I think its more of a chassis thing, im assuming 96-00 arent as friendly.

 

Sarcasm?

 

Looks like ill be ordering them soon enough and ill keep this updated, I'm guessing I have to roll front and rear and ill be alright ..

 

I have the 15x8 +20 on my integra with a 205/50 tire..

I ordered mine using a 2000 miata as the vehicle through tire rack and the wheels fit on the car perfect... center bore and everything is fine...

you can't bet them for the price and style and look... i love them..

 

Must not be, there is NO way mine would fit any more tire without ridiculous camber.
