Spam is good on bread with lots of mustard.
Used 20 inch tires are cheap, as there are so many trucks that come with them as a factory size. I bought a set for $100 installed from a used tire place, I was amazed at the price but that is what the guy told me. I want to say they are 265/55-20?, 31inches tall. Ride wasn't great, they were horrible at grabbing ruts in that truck, a huge handful at times. (Truck drove great with 31x10.5-15 tires.) More sidewall means more flex, less means less. Less flex is more accurate/precise for street performance, but can be a drawback for the same reason. A squishy tire will be more forgiving in ruts, where a low profile will fight the other in ruts and jump around. Depends what you are doing, in my opinion. Our Durango was slightly lowered, so I wanted a street setup. My Excursion is lifted with 36" tires, I love the look of 16" wheels on it, the ride is nicer, and I am not real concerned with high speed cornering. THere is a lifted Dodge in town, I want to puke every time I see it. Looks like 35" tires or so, with at least 22-24" wheels. Dumbest looking thing ever, he took his truck and made it so it is as impractical as possible, just for looks. Lifted with tall tires for offroad with rubber band sidewalls for street handling, in a super tall truck.
