rim offset and size

[motomike368]

I'm putting new rims and tires but not sure what offset the rims need to be as well as what is the best size rim? I'm putting 33x12.5 tires on my truck. Should I use 15x8, 15x10 or should I move up to 16" rims?

3.75" backspace will clear everything. As you go lower the wheel/tire will stick out further. As you go higher it will start to hit steering linkage, wheel weights, etc.

You could do 8" or 10" wide rim depending on the look you like. I would stick with a 15" wheel or go to a 17" rim if you want bigger. Seems like the best tire availability for those size wheels. 16", not so much.

Does the 15" or 17" measurement on the rim make it wider or taller?

More tall-est-er-ish......(just the word 'taller' was too short to post...how ironic.)

Nice...ok, thanks. So if I wanted to get a bit more width out of it, I'd go with a 15x12 etc?

Just buy a 15x8 rim.
The 12 would look stupid.

TIRE:
33x12.5x15
33:Tire Diameter
12.5:Tire width
15: Wheel diameter

WHEEL:
15x8
15: Rim Diameter
8: Rim Width

I think an 8 inch rim looks better compared to a 10 inch. I was running 33's with an 8inch now im on 35's with the 8 inch.

Great! Thanks for all your help. I'm going with 15x8.
