quick question

[sgbruton]

currently i have 275 35 20's on my rear tires but i think i want a little more sidewall, would 275 40 20's make a big difference or would it be pretty subtle, does anyone have these on their car if so please post pics.

check out this website

I use this tire size calculator all the time, check out this website to play with different tire sizes and get the dimensions. looks like the sidewall increases from 3.78" to 4.33", overall tire diameter +1"
