Yeah, I guess they'll "fit" in the fenders, but where and how much will they rub?

A couple of you guys have these wheels already, if not with these tires.
I've heard that the 032R tends to run a little narrower (smaller) than the nominal sizes might indicate FWIW.

Just trying to avoid having to "roll" the rear fender lips.
Thanks. Ed

 

I had to roll mine with 205/50/15 V700s on 35ET rims.

 

Hmmm...
I've got some Azenis in 205/50/15 on the stock rims right now ... without the slightest hint of trouble.
I'm not familiar with those 35ET rims though (width? offset?)

 

35 offset, 15x7. That was also with soft Pro-Kits. If you have a good suspension setup, you sould be okay. Otherwise off to K-Mart for that cheap bat.

 

I'm interested in an answer to this question also. I am planning on running 225-50-15's and 15x7.5 on my 92 Integra GSR for STS and was wondering if anyone can point me to calculations for backspacing and offset to avoid shaving the control arms, rolling the fenders, or using wheel spacers.

Thank you in advance, and I hope this pertains to zygspeed's original topic.

 

Yes in deedee!

 

You might not care, but the 7.5" wheel is considerably heavier than the 7"

6" 9lbs
6.5" 9.2
7" 9.6
7.5" 11.3

That last half inch brings a sizeable weight penalty. It's still a light wheel though and the width does have an advantage...

 

unfortunately for only particular sizes and fitments seem to be available ... i.e., for the ITR 5-lug ...15X7.5

And it still beats the weight of the stock ITR wheel, while being wider!

Oops, I tend to forget about all the 5-lug people in here...

 

Where did you get this figure from? I weighed my SSRs and my scale said something different.

Also,

Good luck with that! A 225/50/15 on that platform, with those wide wheels, will rub everywhere. You'll need to jack the thing to the moon with 1000lb shocks to keep your tires from hitting everything.

Plus, all you need on that car is a 205 anyways. A 225 will kill your gear ratio.

 

Those are the Tire Rack "published" weights. I never thought they were accurate, but did think they'd be in the correct proportion with each other... BTW, this was for the 4-hole models (if that makes a difference???).

So what did your wheel weigh?

I rum 225/50/15 Toyo RA1s on Kosei 15X7 38mm offset. and I had to roll the fenders but other than that no rubbing. I am on 500f/600r eibachs on GC set up about 3/8"under stock height.

don't forget guys, ITR 5 lugs have 5 mm thicker hubs. now when you guys talking about rolling the lip, rear usualy requires, but how about the fronts?

on my delsol I ran 15x6.5 et43 on the front with 10 mm spacer, effectively 15x6.5 et33. no rubbing on front. i have 2 finger gap all around with 560/560 rates. rear with the same setup = rubbing on outside lip, I'm going to have to cut the lip and/or roll it.

will cutting be easier or rolling?

btw, check out http://g-speed.com/pbh/wheels.html

Frank-

I'm not that familiar with spacers, but would a 5mm spacer solve your problems?

I have 15 x 7, 35mm offset wheels with 195/50 15 tires and no rubbing.

For the track, I have 15x6.5, 38mm offset wheels and I'm going to get some Kuhmo 205/50 15's. The .5" shorter rim and larger offset reduce the distance from the outside lip 9mm and from the inside 3mm. The section width of the Kuhmos vs my current RE730's is the same-8.4".

My del Sol is has two fingers gap between tire and wheel well with my current tire/wheel combo. If calculations are correct, the larger tire/smaller width rim should produce no rubbing.

Just a thought, but given your past experience, you probably have considered this already.

 

Thanks guys, you've all been very helpful.

Chris -- part of the reason I ask is because I did see your rear fenders @ VIR a couple weekends ago, I bet the 225's work nicely on the track!

Todd -- I'd like to run 225s on the ITR (if at all possible without what Chris had to do to his fenders), since I feel the car is a bit under-tired (6 inch rim, 195 tread). Especially when I've been running 195/60/14 tires on my first gen CRX which weighs significantly less.

.... the search continues...

 

ED, I didnt read all of the posts, but I am going to try 225-45-15. I have been told I need 5mm spacers in the rear, maybe in the front as well. Kuhmo, and hoosier make this size. I know you like the AO32Rs, but for the price, and the way the kuhmos stick, they are hard to beat.

Bryan

 

yes 5mm does solve it.

i forgot to mention my tire size. 205/50/15 BFG g-force KD's which are fairly wide...

is the section width "measured" or off the manufacture's spec list?

eventually for max performance 15x7.5 et 40 with 225/45/15 will go on the front, with 205 or 195 on the rear...

 

I ran 225/50/15 Kumhos on Kosei 15x7 +43mm and had just very slight rubbing in the rear...I mean very slight. Also, with 560lb springs and lowered a few inches I would also slightly hit the top of my fenderwell on big bumps out on the autox course.

So, you'll be fine probably. My other point was to the guy with the 92 GSR because there is less wheel clearance than what the DC2s have.

 

Only because it's such a good dual-purpose tire (street mostly, some track duty).
The Azenis are nice (and wide in the 205/50/15), but not as sticky in street trim.
I was almost never able to spin the tire(s) on the street with the 032R (with a light launch), but now with the Azenis (200 treadwear) i get spin easily enough. It has been a little cool lately though, and for only $70 for the Azenis I'm not complaining (actually I'm pleaseantly surprised ... much quierer, too)

Thanks again everyone.

 

Ed, I drove Georges car around for a few days on the street, and noticed that when the Azenis are cold, and its cold outside, they did spin, like there was a 2.2l under the hood, I was pretty surprised about this lack of grip... R compounds in the cold are going to act very simular.. They need A LOT of heat to get to stick..

JMO, but I would keep the azenis for the street, and get some 225/45/15 Kumhos on the SSRs for the track..

 

Corey -- I've driven the 032's in the snow once or twice last year, on minimal tread, and it wasn't like the Azenis a couple days ago. .... anyway ... this isn't a YoKo ad!

Just want(ed) to know how much rim/tire I can stuff under my R without modifying/rubbing the fenders!

 

I think for STS and STX you are limited to 7" width.

 

Nope, "any wheels up to 7.5" in width that fit over stock brakes" are legal.

For autocrossing (this is for mojoGSR92), I'd really try to go to a lower diameter wheel and tire setup. With these small displacment Honda motors, we are all at a huge disadvantage pulling out of a gate at the bottom of 2nd. Small skateboard wheels will help by getting you into the powerband in those situations.

so has any one actually tried the 7.5" wide wheels on a 94+ 'teg or 5th gen civic hatch???

 

Well, here is my dilemna. I surely don't have enough money for some Kaizers or Panasports for a 13" wheel to run for auto-x and that is what I would need to clear the GSR front brakes. I would like to use a 14" wheel but there are not many performance tires that I have seen that are legal for STS (minumum 140 treadware). My other concern was that I plan on eventually tracking my car and I would like dual purpose wheels and 13" wheels bring up brake cooling issues. I don't plan on running these wheels/tires on the street at all since I have some seriously bad luck with road hazards and because I live in Ohio which has a moderate winter.

Here's the run down:
13" - Too expensive, not enough brake cooling for when I eventually go to the track.
14" - Not many performance oriented tires besides Dunlop SP8000's (195/55/14) or Azenis in (195/60/14) and too much sidewall.
15" - Great size for track and auto-x, many tire sizes available with performance oriented tires. Also, less sidewall means more feedback and better transient behavior.

My prospects for tire size:
225/50/15
215/50/15 (only one decent tire in this group, Pirelli P7000)
205/50/15

I haven't decided on my price range for tires yet. I'm still looking at what will physically work best, and then I am going to work my way down to my budget. Any input is appreciated.
