^I have 275/35/18's on mine. You will be fine with anywhere from 245-275.

Okay so I still can't decide what size. Does the 275/35/18 fit fine on the front of the car? Any personal experiance would be of great help. Thank you

Did you seriously not read what topgear8 told you? He runs 275/35 on his, meaning he has the same setup you are asking about. Also, that setup is on about eleventy billion rx8s so it will work no problem. edit: lol I'm too slow

It's more than that. Not to mention it's listed in the What Fits thread a bazillion time, the Enkei Owners thread 72 gajillion times, and offered as the preferred size in all quadrillion shops that sell the RPF1s to RX8 owners.

Other than that you have to get pretty specific on your search...

lol

Hey, if you're stock my feeling is 275 may be a bit too much tire on all four corners.

Well, let me put it this way. When I was running 245's on stock wheels MY car felt normal I guess. When I switched to the GT-V's (19's) I could actually tell the difference and it was significant.

I run the same size tire 275 on the RPF1's and you get massive grip at the cost of weight.

But since the wheel is so light, it balances out.

Unless he goes FI there aren't many mods which would increase his car's HP beyond a dozen, maybe. Possible you felt the gearing change effect?

Yeah, I never assumed I got mad HP from switching to different lighter set of wheels and that's not what I was implying, sorry. I guess that effect you speak of, would be the same effect you get when switching to a lightweight flywheel. You're not really making any more HP, you're just using it more efficiently, right?

Well, OP let me say this. Consider the fact that if you're using your car as a daily driver you may not like the jittery ride that comes with wide hard tires, especially if you're on coilovers. Not to mention the noise once you put a few miles on. I'm not saying don't do it, just giving my opinion.

I' considering a different set of wheels in the future, same size, 18x9.5, but I'm leaning toward a 255/35.

yes and no...they are a nice hard tire so they take a while to warm up...once they are, they are fairly predictable as in a "greasy" feel. It's not "loose" as in you feel like they liquefied, but a greasy feeling line...as opposed to a higher end summer / track tire which is much "tighter". But for a daily driver tire, its great. Tracking, I would say a medium. Not great, but does the job and has minor trade offs.

Best bang for the buck in DD applications with light track time.

I think long term track purposes, you should invest into a 17" wheel. I intend to get the RPF1's in 17 later on. R-Compounds and generally most other "track tires" are SIGNIFICANTLY cheaper in the 17 size.

Also the size difference alters the car's final drive and give you a small acceleration boost.

The type of tire also affects the weight. A 245/35 of brand XYZ might weigh twice the brand of ZYX, despite having the same dimensions.

A heavier tire is going to require ALOT more power to move and the impact can usually be felt.

The less weight you have to get rotating the more responsive the car will feel.

That's a good deal if they have life left.

One other "downside" of this combination. Due to the footprint, you pick up ALOT of road noise and feedback. The car WILL track grooves and ripples in the road. Be prepared to have grip, at the cost of always having to use both hands too actually have to "drive".
