I have the Sport Classic II 18" Wheels. I have 7mm and 15mm spacers. My current tires are (240/40/18 Front & 265/35/18 Rear).

Whats the widest I can run with my wheel spacers???

 

I believe it has more to do with the width of the rim. Your rear rim should be 18X10. The optimum fit would be 285/35/18. Spacers are used to adjust offsets.

 

I have 295's on my rear stock 10's and they look good... However, I do not have spacers

I need to get more tread for a few reasons.

1) My turbo kits has put over 100+ more horsepower to wheels and I get wheel spin at high rpms.

2) Wider looks better, makes my rear look fatter and meaner.

Maybe someday I will go to 19" wheels with a better offset but for the time being i would rather max out tire size.

 

So Rear: 295/30/18, what do you recommend for the front?

 

i went 280/30/18 rear 225/40/18 front... Wish i went 275/35 in the rear.... my.2

 

295/35/18 or 295/30/18?

What are you running up front? I need to go wider than 225.

I have been looking at going to 19's but now im thinking just better 18" tires, the widest i can go on front and rear and a big brake upgrade.

 

Any comments on Michelin Cup Tires, Rear: 295/30/18 and Front: 225/40/18 or 235/40/18???
