Need some help with tires
 

Right now i have 325/60/18s they are WIDE!

I want some street tires proxes, ziexs, etc. Now the only size i see them come in is 285/60/18, how much wider are the 325s compared to these? Also i have 18x10 wheels will they fit on there?

40 millimeters wider

So roughly 1 1/2 wider, will they fit on my wide wheels?

A 10 inch wide rim will work with either size you have listed :c:

Ok great:jump:

Now i need to know what the backspacing on my rim is, i want the truck to still look aggressive with narrower tires on it.

Just lay a straightedge across the backside of your rim and measure to the mounting surface that goes against your hub and that will be your backspacing :c:

Thats what im doing hopefully its 4.5 or less:humm:

Street tires are sure cheap!
