Ah cool, thank you. What does the Maverick have stock? 5 and 2?The offset numbers refer to the location of the mounting surface for the rim. A 7" rim that is 5/2 offset will have approx 5" on the inside and 2" on the outside from the mounting surface. The stock rims are roughtly 5/2 fronts & 6/2 rears. So if you want extra width you buy rims that make the first number smaller and the second number bigger as a general rule.
the rears have more on the + side then then the fronts ,I thought I read somewhere on this forum that the stock offset was 5 1/4 - 1 3/4 for the front and 6 1/4 - 1 3/4 for the rear.
