Tire recommendations for my 2011 Nismo/slight track use

ResIpsa

I would suggest that you try to keep your tire widths as close as possible. 255 on the front and 305’s on rear will just give you under steer (I run a similar setup on the street strictly because it looks good). For a track/street setup on stock wheels I would run 275 all around.

And you don’t have to worry about tire diameters on a square setup. Although, your speedometer may be off. My track tires are 245/35/18 all around (6.85% smaller in diameter) and I have experienced no issues.

So your say put a 255 up front and a 257 rear with help with the under steer issue? Keep in mind I only have one set of wheels. So this setup has to work as a weekend driven car.
I am going to keep looking with the sizes you talked about an see what comes up. I would like to have another set of wheels, but right now is not the time for it, so this is why I was looking at the:
F. 255/35-19 = 2.7% Over OEM
R. 305/30-19 = 2.3% Over OEM
Sizes, kind of dual purpose tire. I am understanding your point on the under steer some know. Boy have I got allot to learn.

Thank for the input ResIpsa.

I am suggesting that you run 275’s on the front and the rear. Regardless of what anyone on this forum says, they will fit. Although, your fronts may bulge a little.

Don’t worry so much about the percentage difference from stock wheel diameter. If you are running equally sized tires in the front and rear you will be fine because the front and rear will be the same. I think you would have problems with the VDC if your front and rear tire diameters were way off.

Keep in mind I am only saying this because I think this would be the best setup for track use. Any of the sizes you suggested would work and look much better than a square setup.
