Default Need help picking out tire sizes!

I'm going to be purchasing a set of z06 rims for my camaro (stock height) which are 18x10.5 in the rear and 17x9.5 up front. What size tires should I go with? I was thinking about doing 265/45/18 in the back and 255/40/17 up front but I'm a little scared they're going to rub. Any help is appreciated

Those are way too small for the back. You need at least a 285. I run a 295/35/18 and a 275/40/17 you need an adjustable phb and possibly some hammering to the back. But it's worth it. I also run a 1/4 inch spacer on all 4

Well the thing is stock they're 245; I never take the car to the track and it is a daily driver. I think the highest I would possibly go is 275. Do you ever have problems with such a low aspect ratio?

With a 10.5 and a 9.5 wheel you are going to stretch those tires on the rim. They won't sit flush or how they're supposed to on the wheel. You need an extra inch or two over the wheel size when considering tire size.

So without rubbing or hammering, what do you think I should go with?

For the right size tire on the wheel without going crazy on sizes you need a 275/40/17 and a 285/35/18

I'm going to be running a 245/40/17 and 275/40/17 on a 9.5 and 11" wheel. Don't listen to everyone here and just run whatever you like as long as the tire specs say it works for that width wheel.

A lot of people here like putting tires that bulge on wide wheels like 315's that don't even help with traction.

I have the same setup and I run 295/35 and 275/40. Hammering wasn't needed but i did it for piece of mind. My 295s almost look to narrow for that wheel. From a daily driver perspective my car is WAY more stable and fun to drive then the 235s i had on it stock.

All I know is when I first got my wheels I ordered the wrong tires. 275/35/18 and they were stretched and did not fit the wheel right. Take it with a grain of salt. All I know is when I asked oewheels they gave me those tire specs and they fit perfect

Im running a 17's all the way around but I do have a 285/40/17 in the rear, it looks and fits better then stock "Nitto 555's", I actually want to go wider in the rear...it really does make a difference... I have 17" 275's all the way around on my v6 camaro right now too on c5 z06 wheels, 9.5" wheels, absolutley no issues.

Yeah i really hate the bulge on the wide wheels. And wow 17x11 thats pretty damn wide lol. I am going with 18x10.5 so i think even 275 may be too skinny for me. I just dont know what to go with up front its 17x9.5.

My street wheels are 17*9.5 with 275's all around. I don't have any good pictures right now but I think it looks good to me. I'm not a fan of stretched tires though.

So if you're running 275s on a 17 inch rim, 285 should probably be my lowest lol. How do you think 265 on a 17x9.5 would be?

275mm on an 11" wide wheel?

I hate the look of a streched tire. Guess this is just another matter of opinion.

...not to mention the increased probability of a bead unseating on a hard corner, or when you touch a curb by accident. Watched that happen once. Two wheels contacted the curb while this guy was attempting to park his TA with new wide, stretched tires. Both wheels got bad rash, one got flattened instantly. Hilarious for everyone but him.

275 is too skinny for an 11" wheel (although it will "fit", it will look and perform terrible compared to running a 315, but the honda/VW kids will give mad prop y0!)
Anyway, some tire companies run more narrow/wide than others, but 315s will fit your 18x10.5 wheel and look good:
Do you see any bulge here?


From the factory the C5 Z06 comes with 265 front, 285 rear. You can run 275 front, 315 rear.

That picture is kind of misleading as Falkens are notorious for being overly narrow. Most people say a 275 in a falken is like a 245 in a bfgoodrich/yokohama.
