Default Why 35 profile on 18 x 9.5" rim??

It seems like everyone who has 18" rims are running a 35 profile tire - no matter what the width? Why do you guys do that?

It seems as though, according to the miata calculator, that 255/40/18 is an (almost) perfect match for our stock 225/45/18 - same with 275/40/18 in the rear. Yet everyone seems to downsize them a bit. Is it because with a smaller 18" rim, the more meat of the 40 tire makes them look smaller? I've gone through a lot of threads/pictures and can't seem to determine if that's the case.

I personally was planning on getting the Rota Torque's with a 40 profile tire, since Wisconsin roads suck - I need all the cushion i can get. However, I don't want to get the 40 if it looks like crap.

Thanks guys

well a lot of people are running 275/35 in the rear. to each his own i guess - I'll just give the 255/40 and 275/40 a shot and see how that works out.

thanks for the pic walkert. Looking at your 255/35's on the front...I can't imagine going up to a 40 - even though it's closer to stock diameter. hmm...dilema

I am dropped on eibach pro kit. I have a friend that went with the 40s and it makes the rims look smaller because of the extra side wall. That is why I went 35. I have hit plenty of pot holes and no problems.

You're tire gap grew when you went to a smaller diameter tire.

I'm kinda running crazy sizes.

275/35R18 fronts

285/40R18 rears.

Yes my 285/40 tires LOOK SICK and DO NOT RUB and are AWESOME.

I'm actually thinking of a 295/35 when I get new tires in the future . . . will have to inflate them less for my 9.5" wheel.

That's going to look reaaally nice once you get those Eibachs in there. Did you get the wheel/tire combo through Subydude?

Smaller diameter tire for better acceleration. It also looks a hell of a lot better.

When I had 18's I ran the same size tires. It looked great. IMO 275/40 tires are too big for my taste. Too much sidewall for me.
