    Square 18x8 or 18x8.5?

    I'm about to but some wheels and I am wondering what I should do here? Should I run 8 all around or 8.5? Any real differences?

    I would go 8.5's all around. I have 8's all around and should only put a 245 on the rears (currently have 235 square setup).

    My Sons ZHP leaves me wanting 255's back there, but I think it may be a far stretch on an 8" rim, though I'm sure you could do it.



    What is your desired tire size? That's what we need to know.

    It's not a big diff, but I'd think 8.5 all the way around would look best. To some, 8's in the rear just seems a little small. 8.5 in the front is not a tough fit. I'm going 8.5 square soon.

    Edit: BTW, what's the story behind your avatar?

    What are the current tire sizes? It'll say on the sidewall. That would help to gauge if you're happy with the current setup. Once we have a starting point we can help push you in the right direction. Smaller tires (usually smaller rim) = cheaper.

    OK. I would say if you have no preferences, go 8.5 square, as John boy indicated. What rims are you looking at? What offset? What brand tires?

    8.5" definitely.

    Tire sizes could range from 235-255 and they'll all fit, even the 235 won't look stretched.
