26x9.5x14 QTP on 5.5” Rally Wheels
Found this short blurb.
"Wide tires on a narrow wheel can affect wear, handling, and performance depending on what you are doing. If the tire is too wide it wont support the rim properly and could lead to some very odd handling and premature wear".
"If the rim width is too narrow, you pinch the tire in and cause it to balloon more in cross-section. If the rim width is too wide, you run the risk of the tire ripping away at high speed. For 50 -series tires and above, the rim width is 70% of the tire's section width, rounded off to the nearest 0.5."
