i have an oppertunity to buy a set of toya RA1s in 225/50/15 brand new for $200.
this is a deal i can pass up... im just wondering if they will rub or not. i know the stock r rims is norrow but i cant afford new ones... so i just need to know if anyone else is running same size and has issues rubbing.

 

I would not put them on stock rims... would feel like ****. If you had 7inch wide, then go for it.

 

I'm pretty sure the rear will rub the trailing arm.

As for the front, since the stock wheels have really high offset, I think it would rub the inside also.

 

They'll rub at full steering lock up front on either side. Probably makes a dime sized spot on the inner fender where it removes the undercoating. No serious damage.

Rears will rub the trailing arm. You might be able to clear the arm with a 5mm spacer. Anymore than a 5mm spacer requires replacing the rear wheels studs with longer ones.

 

As already mentioned, stock 6" wheels are Not optimal for the tire size you're asking about.

They will rub. Both at the front lock to lock and the rear LCA's, not a huge issue but there will be rub and wear.

And finally, despite the first 2 points if you can't afford the wheels for the tires to perform optimally then I'd pass and save the cash or spend it on something else that you "need" more urgently.

RA1's are DOT R compounds for track use. Answer to yourself if these are something you feel you're ready to use if you aren't doing so already. If you really think they're a deal you can't pass up then buy them and store them till you can afford wheels to mount them on. As long as they are stored properly and or used relatively soon, ie 12 months or less, you "should not" have any issues. But if they're beat or heat cycled out a bunch already you might just want to pass till you are in a better position to accomodate them.

Yeah. I used to autocross with 225/50 in front. It rubbed a silver-dollar worth of undercoating off the inside.

Rears don't fit at all without a spacer.

This is assuming stock height.

 

i am definetly using these tires for track only tires. i am currantly on azenis rt-615s for track only and am selling them.... i would like to run these until i can trade for a better size tire/ proper rim.... i figure even tho badly sized a true r comp should still be a faster tirm then the comp.
im actuaally track racing now solo1 events and i have another event this weekend but i figured it would work out to improve my times vs. azenis

 

bump

 

Ultimate grip will improve but turn-in will be sloppy.

It's up to you man.

This is an extraordinary deal, and if they are new you should definitely buy them.

Then you should sell them to a Honda Challenge competitor for a profit and buy yourself some 205-50-15.

 

If you don't buy them, please let me know how I can buy them for that price...!!!

 

i have a set of Kosei K1 for the ITR. im getting the 225 RA1s. i heard they will run at full lock.

but we'll see. if i must, ill get spacers for the rear at least.

 

I just realised the original poster mentioned that he has a stock suspension.

I am not sure that R compounds on a stock suspension is always the safest thing to do, and I want to make sure the original poster has considered all the consequences.

I would consider that a <U>serious</U> overstatement. Sure you get some lean in the R, but it starts out pretty low. Are you really worried about the car flipping?

Ken Sax has 17,327.3 track miles on stock suspensioned cars, with R compounds.

Oodles of autocrossers in stock cars autocross weekly with stock suspension. Their quick transitions seem to me to be more likely to cause the car to flip, and I've never heard of an R getting up on two. If he had a Rabbit or something, I'd share some concern.

I'll take your word for it, then.

I never had R comps on my ITR until I went with the first 400F/500R suspension.

 

Never had an issue on stock suspension and R comps.
Never had an unsettling moment with them on stock suspension.
You just don't get the most even wear with stock suspension and R comps

Maybe (unsettling feeling) on concrete... but I never tried that autox stuff with R comps

 

Have either of you ever been on a road course with stock suspension and R comps? I guess that's more what I'm thinking about.

 

That's what I was talking about

Chris - who has ONLY used R comps on a road course.

 

OK. I've quit worrying, then.

 

225/50/15 is WAY to wide for the stock rim

205/50/15 azenis are pushing it

get yourself some correct size tires, width is not everything

225/50/15 is dangerous on stock rims

I started autocrossing on Hoosiers on stock suspension 4 years ago. And have run the laundry list of tires since. Never had any negative issues other than the uneven tire wear as mentioned already. Without Adjustable camber you'll just not use all of the tire.

I've tracked AVS 90's, Azenis 215's and Ecsta V700's. Never had any negative issues with the V700's. I actually like R comp's better on the track as opposed to Autocross simply because they are able to heat up and to me feel more predictable, but that could be my slow mind just catching up.

The only car I've seen flip at an autocross with sticky tires was a brand new Focus ZX3something-or-other. Ironically it was only on new Azenis .

I think the R comp issue with stock suspension comes into serious play with soft stock suspensions.

LIES!!!

Check the manufacturer's rim width recommendations. Kumho recommended a 6" wheel for their 225/50R15, and I autocrossed/tracked it.

Hoosier recommends a 7" wheel for the 225/45, I recon, but the winners autocrossing with them on ITRs were using them.

However, yeah, SOME tires would be silly/dangerous/ineffective on the 6" rim in 225/50 size.

Novice isn't REALLY the right word, is it? You'll get some war stories of cars up on on 1 or 2 wheels in the RR/AX forum. Cars get out of shape at all levels of autocross.

But yeah, absolutely, high-CG, soft suspension, insufficient swaybar cause other cars to roll. On the ITR, with it's "stiff" suspensiona and "huge" swaybars, I've never heard of any issues. I use quotes, because if you compare that suspension to just about any other street legal car, it's stiff with huge swaybars.

Yeah JooR right, maybe "Novice" is too much of a generality. This is the car I was referring to though about 3 years ago:

What i meant to say, I suppose, was what j00 said. 'not using all the tire' instead of 'uneven wear'. (on stock suspension that is)
