I realized that instead of buying new wheels, maybe I could just buy a different size tire. So, trying to take advantage of your expertise, has anyone used 245/40 (front) and 275/40 (rear) x 18" on the stock 350Z touring wheels?

Thanks

 

I just read on another forum that 255/40 and 275/40 x 18" may work?

Anyone using this size?

 

What would be the purpose of different size tires rather than to OEM sizes?

 

I have a 2004 Touring Z and am in the market for new tires. I would perfer not to have to replace the wheels. I saw this post and wanted to see if anyone else has done this and if so, is the VDC okay? The tires I like are Goodyear Eagle F1 GS-D3.

Thanks

hey dude,
i'm the goodyear tire dealer out in calif
the sizes u wanna run are:
frt 255/40/18
