Wheel width and height?

[nosaj]

I have 20x12's with 38 15.50s and 8" lift. Chrome is starting to come off of one wheel so I am thinking about buying a new wheel. My question is if I put 20x10 wheels on my truck, will it make my truck any taller or leave 12's. Reason asking I have seen a few trucks with 10's with same setup and look taller for some reason, maybe just in my head.

I also have been thinking of going to 40s when it's time for another set of tires, so if that plays a factor, let me know.

If you get 10 inch rims you will have the mushroom effect on your tires.

With 15.5 inch wide tires. I strongly suggest you stay with the 12 inch wide rims.

Also you should find out what size rim is recommended for your tires. If your rims are to narrow it can cause problems with the tires. Usually the bead will not keep. If you go out into sand dunes or have to air down your tires and your rim is to narrow you most likely will cause damage to your tires.

Stay with 12's for sure,I have the same size tire and trust me 12's is the way to go.
