    Default Check my math, please...

    My neighbors have a '03 Silverado K2500HD they took on trade. They had a tire issue, and there is no spare.

    The truck is riding on 275/55R20's, with Mazzi Maximus -750 wheels (based on pictures I could find)

    Question 1: Is 265/75R16 on a stock wheel close enough to get them to a tire shop? The two sizes are like .3in difference overall height.

    Question 2: Does anyone know the standard size of the Mazzi? The innerweb got me as close as 20"x9", but I'm curious on backspacing.

    The truck is rolling now, but they're interested in having a spare on hand.

    Question 1, the answer = yes.

    If the tire is round and the rim fits the bolts and clears the brakes it will work.
