I see a lot of guys running different tire other than stock on your 20 inch wheels or even different wheel and tire combos. I want a slight bit shorter overall tire size than stock 275/55/20. If I go shorter will things like computer bre off? what do you all do? :help:

Any thing shorter than 275/55 looks funny on the truck unless you drop it. But a nice loking tire is a 265/50r20lookgs good with the 2/4

275/60-20 = 32.99
275/55-20 = 31.91
265/50-20 = 30.43
275/45-20 = 29.74
255/35-20 = 27.03
225/35-20 = 26.20

also the 285's 295's and 305's are going to be wider.

or you can just do the math.
the first number is the width in MM
the second number is height of the sidewall as a percentage of the width
the last number is the rimsize
25.4 is a constant (the number os mm in 1 inch)
2 is a constant (the number of sidewalls in the total height)

(width * .sidewall/25.4)*2 + rimsize

so 305/50 r20
((305 * .5)/25.4)*2 + 20
(152.5/25.4)*2 + 20
6*2 + 20
12+20
32" tall

or in a calculator
305 * .5 / 25.4 *2 + 20 = 32
