It appears as if this tire is wider than most other 225mm tires. Is it OK to run in the back on an AP1 wheel?

Here are the specs from the tire rack site:

Yes. This tire would be my first choice for street/occasional track use if money were no object...

I'd rather have these in 225/50-16 in back than just about any other tire in 245/45-16.

My *opinion* (take it for what it's worth!) is that the benefits of 245/45-16s over non-OEM 225/50-16s for safety in street driving are greatly overstated!

I could be wrong...

Thanks. Anyone else?

The tread stagger on the OEM S02 is 7.1" front and 8.5" rear. You're looking at cutting that stagger in half.

My *opinion*...and I could be wrong...but use at your own risk.

Personally...that low stagger does not suit *my* driving style, but others may have no problem with it.

BTW...if you are spending that much money, why aren't you considering the oem S02?

Wouldn't this be a "better" tires than the S02? Same treadwear rating, but more grip?

Personally...on the street I like balance more than ultimate grip. But that is me. And not to say I run crap tires on the street. I think the difference in grip between the RE-01R and the S02 on the street is the difference between: "oh man I really shouldn't be going this fast on the street" and "Officer please don't take me to jail...I have a wife and a family and a dog and a cat".

These would be primarily used for autocrossing. I just don't want to buy R-compounds. I may travel up to 2 hours away for an autocross, and I don't want to carry an extra set of wheels for me. I would however like something sticker than S02s.

vs. the RE01R,
S02 is more expensive.
S02 is in a lower performance category
S02 is not as highly-rated within its performance category (TireRack survey)
S02 is two generations old (succeeded by S03, which is succeded by RE050)

The *only* thing the S02 offers is outright physical size. I don't think that's nearly as important as other factors.

I would bet that the difference in real-world f/r balance between the S02s and reduced-stagger RE01R's would be quite small, and shouldn't amount to the difference between a "safe" driveable car and an unstable spin-prone beast.

I'd WAY ruther 'ave the RE01Rs...

im running 225's up front and 245's in the rear on stock AP1s it seems to work fine, feels more stable etc...

I have the 205 front and 225 rear RE01-Rs on my AP1 wheels on my stock s2000. I've never had an issue with oversteer. I've done about a dozen autocrosses on them and the have awesome grip. The car is very well balanced and just sticks.

I have no experience with the S02s, I bought my car used with some awful Kumho 712s on it, so I can't comment on how the RE01-Rs compare.

I think the RE01-Rs are a great value and a great street tire, regardless of price. I bought mine back before Tire Rack lowered their prices, so now they are even cheaper.

Go for it, you won't be disappointed. Only down side is the speed rating is lower than the stock S02, so one tire shop wouldn't put them on for me (they had a policy of not installing tires of a lower speed rating than stock). They are good to like 130 mph, which is more than I'll ever go, so that didn't matter to me. But the RE01-R load rating was higher than the S02s.
