Has anybody tried putting wider tires on, especially on the rear? I'm curious whether 295/30/19 would fit without rubbing the fender.

Similar thoughts and questions regarding 275/35/18 in the front.

I'm guessing they might not fit with the Nismo rim +30 offset....but maybe with some same-size wheels with a +22?

I'm basically trying to see if I can run SCCA B-Stock (can change tires and wheels, but no fender rolling and wheels must be same dimension as stock) with the same setup that I would run for HPDE.

 

Maybe grab some measuring tape and angle the tape at the angle of the tire offset, just to get a rough idea, or take it down any tire shop and they can probably give you a good estimate.

Having the tires angled the way they are will probably give a few more mm unless it will mean the inside tire wall will hit something.

 

Might want to post this over in the wheels/tires section. There's probably someone who's put wider tires on the Track/GT wheels and might be able to give a better idea. I've heard of people going with 285 in the rear, but I don't know about 295.

I would guess that the tire sizes would be ok since the NISMO in stock form sits pretty high up, but I can't offer anything other than an uneducated guess.

 

Solo is planning on going pretty wide, 275/35/18 and 295/30/19 just like you described.

I had a GT/track setup previously and went with a conservative 255/275.

With 275/295, I'd plan on some type of fender rolling. But the Nismo isn't that low so you might have a chance.

 

I have 285/35/19 on my GT's rears (same wheels). 295 would be fine too if your tire manufacturer considers a 10" wide rim sufficient. Your tire+wheel diameter will be shorter than OEM so I doubt you will have any rubbing issues.

Having a 275 up front though is probably too much. 8.5" isn't wide-enough for that. I have 255 on mine and sidewalls look just right, I wouldn't want any more bulge (there's a sentence you don't hear every day!).

 

The Nismo edition wheels are 18x9 and 19x10. You can definetly run a 275/35/18 on a 9 inch wide wheel -- the question in my mind, is will it rub with the stock Nismo +30 wheel.

 

I'd expect the 275s to have a higher level of grip, but would they affect turn-in any or slow the car down due to weight?

 

Yes, fronts are 9" indeed; I was mistaken. They are the same wheels as on the GT, just different paint with an engraved line on the spokes instead of the 3 dimples.

I still wouldn't go with 275s on the front due to aesthetic reasons. Also, you might want to run your intended front/rear combo through an online diameter calculator to see what the different would be compared to OEM to guess whether or not you are likely to have VDC issues.

 

We don't have VDC.

 

I have a 2008 Nismo. I went with 285/30 19 on the rear. Bridgestone re050a. Looks great no rolling and fit perfect. I left the fronts alone. I could go up to a 35 but no 1 had the BS in 35 only 30.

PS. I did try a 295/30 on they rear and the pop out and looked ugly.

 

post a picture, those rims are just screaming for larger tires. Do your new tires have the rim protector?
