Recommended Tire Size?

[barrrf]

Good afternoon fellers,

Picked up a set of 18x8 and 18x9.5 TSWs.

Im not real confident Im picking the right tire sizes and would like some confirmation Im not way off if you happen across this thread and have time.

Im thinking 245/40 on the front and 285/35 on the back? I wouldn't mind a little bulge to the tire. I definitely don't want stretch.

Thanks!

Or 245/45 & 285/40?

Those seem like odd tire sizes though.

I'm running 245/40/18 5.0" BS & 275/40/18 5.5" BS

Very tight fit in the rear, my car wouldn't take any wider section width without mini-tubbing it. Rolling the fender lips would help. I had to massage a couple areas on the inner fenders at the frame also.

I have oodles of room in the rear. I can go up to 305s without rolling the lip (but they wont fit on that 9.5 rim). I have 285s currently on a 17. Im just wondering if stepping up to the 18 and 285/35 if there would still be a decent amount of sidewall.

Its a tough balance trying not to completely blow my bank account out and still have a decent sticky rim/tire combo.

Sorry.......don't know why I assumed Camaro

Most performance tire manufacturers specs list acceptable rim widths and section widths for a given tire size. Stay within those specs and you should be fine.

Tire size calculator:

This will give you approximate, not actuals.

Also for any tire size/brand you are considering, Tirerack.com has all the specs such as reccomended rim width (but not the sidewall height) listed. Go to the site, search tires by size, enter one size you are considering and click the specs tab for other sizes/specs.

Good luck!
