Anyone have experience with 285's on 9-inch width wheels?

Post by djrogers1 »

I'm getting some conflicting advice for sizes on RE71R's for my Mustang. It has 19x9 fronts and 19x9.5 rears. Some folks say 285 is too wide for those fronts. Anyone have first-hand experience with this, or good inside knowledge on pros and cons?

Thanks!

As long as they don't rub they will be fine I have 285 on my stock rims and 255 was what came on the car.

I ran 245's on an 8. I probably wouldn't pinch that much tire on a 9, but JY's right - if it doesn't rub, it will work. May not be optimal, but will work.

I was running 275 RE71R's on 10 inch wheels and loved it. I don't think the tiny bit of contact area you gain from a 285 would be worth having more sidewall flex, and they aren't as tall. I wouldn't think you need to be geared any lower. I would go with 275's. The tires will be happier and so will your wallet.

The 19x9 fronts are 45mm; the 19x9.5 rears are 52.5mm.

You should be ok on the front, but if it is close to rubbing use a 1/8 or 3/16 spacer and that should get you to where it won't rub.
