My car 2008 350z Enthuasist with TCS and no VDC. with 18 inch track model wheels.

I am puttting Nismo LMGT4 19 inch wheels on my car, and wanted input on tires.

I have decided between two tires the Goodyear Eagle F1-GSD3 or the Michlein Pilot Sport A/S.

I have used these tires before on my G-35 and Mustang GT and both were great.

My question is on tire size. The recommended size is 245/35/19 front and 75/35/19 rear. the respective diameter is 25.8 front and 26.6 rear on both tires, which is the same as factory diameter.

If I go Michelin I was going to go 245/40/19 front and 275/35/19 rear. the diameter on the michelins are 26.4 for the front and 26.6 for the rear. this is only a .2 difference in tire height instead of the factor .8.

Would this give me any problem with TCS?

I hada 2005 G35 sprot with Brembos and VDC. I put on BBS rims and 245/45/18 up front and 275/40/18 on the rear and had no issues whatsoever.

Is the 350z more succeptible to tire sizes then the G35, or is the traction issue just overblown?

 

The front tires are taller than the rear. I give this a thumbs down.

 

You are using a general guideline. Not all tires are the same. As for my research all 245/40/19 tires are about 26.7 in diameter, and the 275/35/19 are 26.6 in daimeter. The one exclusion is the Michelin Pilot Sport A/S in which the 245/40 is actually shorter than the 275. check tire rack or michelin on the tire specs.
