I just won a set of 18" Z06 wheels they are 18X9.5 . I am being a cheap A$$ about tires. I want to go with a 245/40ZR18 by Kumho Ecsta Supra 712, out the door road hazard and lifetime balance and rotate is 655. My buddy says that 245's are to skinny for 9.5 inches. The tire guide said that 245's WILL fit a 9.5" rim. he thinks i should 275/35's which are about 200 dollars more. I am trying to get a good set of tires for a low price. My buddy says try to get those yokohama AVS dB S2 which are about 30 more dollars a tire but have a tread wear rating of 320 vs the Kumho's @ 280. Does that much tread wear rating matter. I have been to tires.com and tirerack.com. Tirerack offers road hazzard but charges shipping. Tires.com offers no road hazzard and NO shipping. Lose Lose situation. The 655 i quoted was a local joint here in town. So Help me out as much as Y'all can, Thanks

i believe that 245's can fit a 9.5 inch wide wheel..but it will most likely look funny, and considering the thin tire size for the wheel, if you happen to catch a curb ever, you're gonna catch the wheel lip before the tire. it might be worth it to buy the wider tire just in case so you have less of a chance of scratching the hell out of your wheels.

i figure a higher tire teadwear rating is always a good thing.

personally, i would go with the 275's.

It's real simple. You may be able to run that 245 series tire but the 1st pothole, road dip etc & you'll run a damn good chance of bending your rim. You can spend more now & do it right or half a$$ it & pay for it later, not to mention that profile would look funky. A lot of people run 275 35 ZR18's. I ran that but switched to 285 35 Nitto Extreme 555's. The ride got a whole lot better & the set up filled the wheel well even more.

I have a set of 18X9.5 rims all the way around, and I run 285X35 tires on them, it's the only way to fly. 245's will not have enough side wall and will look like rubber bands on your rims, not to mention a VERY uncomfortable ride.

I am always amazed at the lengths people will go to to save money on tires.

Dude, they are the only part of the car that touch the road. On top of all that, with better tires(and wider), you can brake/handle/accelerate better. Name another part of the car that can help you do all that in one change!!

I have the 18x9.5's as well, and ran the yoko avs db tires that were mentioned. 275 35s. I like them a lot, hella better than the crappy goodyear tires that came with the car.

They keep the overall diameter of the tire just about the same as the stock 245 50 16s. No significant changes to the total height of the tire with the 275 35s. 285 35s are close, but are slightly larger. All that means no reprogrammming of the speedo values.

I would love to have had 285's, but that tire is not offered in as many flavors as the 275 35. That makes it a tough choice.

My recommendation.......275 35s.........Good luck..
