tire width?? - Toyota Nation Forum : Toyota Car and Truck Forums

does anyone have an idea of the widest tire I could run on a 7"wide wheel? I currently am using 205mm... could I go as far as 225's??

You can easily go 225 on a 7" rim. You can go wider than that. The stock 15's are 15x7 rear and have a 225 on them.

I'm pretty sure Jeff Fazio (Hyde) had 255's on a 7.5" rim (I think) at one point.

And somehow, I double posted! Disregard this please!

The widest street tire you can get on there with very little issues is a 235.
That is what I run on the back of both of Jekyl and Hyde on the street.
A 17X7 with a 235.

NoShoes Moore actually squeezed a 245 onto the same rim, but I do not recommend that.

I have run a 255 drag radial on a 16X7, but DRs are designed entirely different.

thanks guys

J&H.... you said with "very little issues".... please explain. I just don't want to hit a bump and pop the seal around the wheel! I think I'm gonna go with the 235\50\17 brigdestone potenza's.. for the rear of course. and stick with my 205's up front.

As indicated in my post, you will have very little issue .. if you went bigger, I would be more concerned. As for the seal popping, I set the Weatherly Hill Climb record last year on a 235 Falcon street tire. I wouldn't expect you to ever put a tire under that kind of pressure ... and if you a hit bump bad enough, it's not going to matter wwhat size tire is on there.

MR-355-5sfTe · 06-12-2005, 06:29 PM

that's good to know.. I don't think my mr-2 will be making any hill climbs in the near future! thanks again for the input.

Hyde,

I'm getting new tires soon ( bought the car with 17x7 front and back ), 215's all four atm. They rub up front and wanted to know what tire size you'd recommend for the front to eliminate ( or reduce ) that problem.

~Thanks

MR-355-5sfTe · 06-13-2005, 01:48 PM

a friend of mine had the same problem... with the same tire size... so he has put a 205 up front.. hasn't rubbed yet

JekylandHyde · 06-13-2005, 01:49 PM

oh, MR-355-5sfTe, I would recommend a 215 up front!

gkcopperdrag, you should not have the same size tire all the way around on a MKII MR2.

Where are they rubbing? Are the rubbing the strut or the fender? There is no way a properly sized 215 should be rubbing up front.

If it is hitting the strut, it sounds like you have the wrong off set on the rim. You may have to go to a spacer or a different wheel.

If it is hitting the fender it sounds like the tire is way too tall.

fender, will grab the exact size when I leave work~

215/45/R17

The top of the tire on the inside 2" is worn down significantly more than the rest of the tire.

Thanks for any feedback~

JekylandHyde · 06-14-2005, 08:38 AM

That's your problem! ... your tire is way too tall.

A typical 16" for a MKII up front is: 215/45/16.
A 215/45/16 = 599.9 tall.

Let's talk 17s. If you have a taller rim, you need a SMALLER sidewall.
If you run a 215/40/17 = 603.8 tall (it is a little taller than stock)
If you run a 215/35/17 = 582.3 tall (it is a little shorter than stock)
You 215/45/17s = 625.3 tall! No wonder they are rubbing!
