I'm just toying around with the idea of adding some rims to my truck, but i don't know if i should look at 18" or 20" rims.

Is there any performance difference or ride quality between the two sizes?

I also pull a fair amount, so are the wheels going to hold up compared to my stock steel rims?

Also, what about offset?

Any recommendations?

As I said, I'm just toying around with the idea, but I need to have an idea of what I need to look for.

Thanks
