Ok, I'd like to know once and for all what the widest tire size possible on the RSX is with these conditions:

- maintaining same overall dimension of wheels *a must*

-on stock rims

-without rubbing *a must*

I was under the impression it was 225/45/R16

at the track the other day a guy had 225/50/R16's on his type S. I asked him if his speedo was of and he asked why, and continued to state that was the right size. Now correct me if I'm wrong...please..

OLDMAN, I know you know the answer to this I'm just awaiting your reply.

I have seen a few type S guys having 225/50/16 azenis on their stock rims, it works. the car itself can go to 235, havn't seen any 245 yet.

Using the stock rim the widest tire that will fit and operate at the correct flex point would be a 225/50/16. A 235 needs a 7"rim as a minimum. The diameter of the 225/50/16 is virtually identical to the 205/55/16 on the car. Here is a calculator with visuals:

So...OLDMAN. The guy from the track had the right size?

Why isn't 225/45/R16 I thought that every time you go up a size in width you go 5% less in sidewall..which would equate to 1 up width 1 down sidewall profile...

IDK, I guess I was wrong. The only thing is that I thought I heard it from you OLDMAN that the proper 225 width size is 22/45/R16 I guess I read it wrong, or remember it wrong.

Thanks again...

THEOLDMAN

It seems to make sense because you are going up two sizes in width to come down two in aspect but the math doesn't support it.

205 X .55 = 112.75 Height of sidewall in mm
112.75 X 2 = 225.50 Height of both sidewalls above and below
225.50/25.4 (mm in 1") = 8.88"
16 + 8.88" = 24.88" (stock wheel and tire height)

225 X .50 = 112.50
225 X 2 = 225
225/25.4 = 8.86"
16 + 8.86 = 24.86"

The .02" isn't going to affect anything that much.
78.16" in circumference for the stock
78.10" for the new
810.64 revolutions per mile for the stock
811.27 revolutions per mile for the new

This is about a 4' difference in the rotation of the two tires in 1 mile.

yo honda_pilot, did the guy at the track have 225/55 R16?

I bet if you went with some 225/50/16 potenza's you would get some pretty descent traction. And the handling would be better.

THEOLDMAN

The best one's would be the OEM's for the front tires on the S2000. S0-2's S0-3's would be second choice. But they would be useless in the winter, or anytime the temp is below 50* they just don't perform like they are supposed to. I hang out with a group of S2000 drivers that track their cars, a lot, and most of them put the car away for the winter. But there are some who just throw on 4 dedicated snow & ice tires and have a blast all winter long. One is a guy I met from Calgary last summer, he drives his S2000 all winter up there.

would you happen to know if i could run on 205/??/15 on my ep3??

97 TYPE-R 312

you can run a 205-50-15 on stock EP wheels.
