Thanks for the info and your help. I'm not sure how you calculate the size fittings, but you're sure I won't have a rubbing problem using 255/40/18 and 285/40/18 sizes? Thanks again!

 

Also, is it possible to use my current rears 245/45/18 on the front instead of the 255/40/18 you suggest? The tires are nearly new, it would be nice to reuse them... I'd still buy the 285/40/18's you recommend for the rears. TIA!

 

You'll kill the stagger if you did that. The recommended sizes for your new wheels are 245/40/18 and 275/40/18 front and rear. However, the 255/40, 285/40 combo will work.

245/40/18 F and 275/40/18 R these size are easy to get.

 

i have a 05 G35 coupe. i have installed 245/35/19'" front and rear 285/30/19"

no problems at all. you could go even up to 305 rear but your car will need rolling first.

I ordered G-force 255/40/18 for the fronts and 285/40/18 for the rears. It should look sweet, I just hope they fit!!!

 

is this going to fit on my 03 g35 coupe 255/30/20 fronts and 285/30/20 rears?

 

I currently have 245 front tire on a 9.5 rim and 275 tire on a 10.5 rear rim..what's the widest tires I can go for my car without spacers?

 

Should have asked 10 yrs ago
