Ok, yes people may say it looks stupid or whatever, but its not your car, so who cares. Not trying to be a dick just saying, to each his own. The 26" rims I posted were 10k.
My 24"s weighed in at 100 lbs each when I had them shipped. (That was with the tire mounted) Im not sure what 15" rims weigh with 33" tires. I'm sure someone will.
Stopping power, yeah bigger brakes will help out a ton. My truck stops way faster with stock 15" rims no question about it. But, you have to adjust your driving a little.
Pot holes... I have hit enough to say this, they hurt. They dont do anything to the rim, or tire. I hit some construction with them on the interstate one time... Huge hole, 73 mph. No dents, no damage, it just hurt a little.
Just to compare, here is my truck on 20" rims.
24"S
This might be better, 15" stock, 20", 24"
