So i shouldn't get wider tires on stocks?

llamaboiz

hahaha no of course you can, im sure you can go 265 on the stocks without problems, it is afterall only 1 size up. 275 thou... pm combfilter, im sure he would know.

265 sounds good. 275 is what i want for the rim's im going to get in the future.

I really don't think bigger then 255 on the rear is a good idea.

On a 8.5" rim, 255 is the maximum size recommended by most tire manufactures.

On the front wheel you can go to 235 or 245.

I'm not getting aftermarket wheels so I was going to ask the same question. 255 looks a little too thin for me. So why is it that we can't go 265 or even 275?

My Camaro runs 245 and they are 8". If you can run 245 on 8" you can run more then 255 on 8.5". 275 might be pushing it a little it might depend on the manufacture of the tire.

they all vary even though they say the same sizes. kind of like shoes. Wait tires and rims are shoes on a car.

Just remember that there is a dependancy between rim and tire, a 275 on a smaller rim will not be as wide as on a larger rim. you'll get more sidewall in the end on a smaller rim. All tires are not equal either, a 255 brand x is not identical to brand y. Do some research, maybe ask tire rack for a recommendation on a "fat" 255 or a 265 that will better fit a 8.5" rim. Either way you may not get the aspect your lookin for with the stock rim.

The proper next wider size is 265/35/18. You will not notice the extra width ( about 1/4" ) but the height is about 3/8" shorter. ( depending on brand ) which I am hoping will help even the fender gaps front & rear, maybe even increase acceleration from lower effective gear ratio. I recommend this size for reasons above plus availability of tires in this more popular size.

I have 2008 IS350 stock wheels + tires.

What size tires did you guys buy to even out the difference in size from front to rear. I want thicker (more sidewall) in the front to match the rear.

Please let me know.

Thanks.

Not worth the trouble. If you are going to do it, do it right with plus 1" on wheels.

changing the width to 265or275 changes the width rather than the aspect ratio... if you want.... get a 45 profile tire... that is what makes it beefier.....

Get a higher ratio tire... like 225/X/18 ...

^^ pick a slightly bigger X than you have now..
