It's about time for my first set of tires on the z. I'm still running the stock '07 rims (Enthusiast), and have narrowed down to 2 tires. The Goodyear F1 GS D3, or the Falken 452.

Both have very limited availability. What size should I be targeting for front and rear's? I appreaciate all opinions.

I was thinking 245/40 18 front, and 255/45 18 rear. What do you think?

Pleas don't refer me to the tirerack review.

 

Stick to OEM F 225/45/18
R 245/45/18 Buy new wheels for wider tires..

 

I went with 275/40-18 in the rear and they perform fantastic on stock rims. Many guys disagree, many agree.

I like the look and definetly the performance.

 

33.5 mm is an extreme difference in tire height. I don't like it.

 

I'm going to have to say you don't know how a tire should perform.
Tires combo's for the OP, 245/40 front 245/45 rear, 245/40 front and 265/40 rear and if your seriously in the canyons/trackdays on your stock wheels 245/40 front and 255/40 rear. Of course you can always run stock sizes too.

 

Always happy to help. If you have other questions please do not hesitate to waste my time.
