How many people think they should be able to install a set of tires like what's on some of the late model vehicles in 20 minutes for $15 each, or less? I know mounting tires can be a tough job, for not nearly enough money many times. Like spending 4-5 hours just trying to get air to seat the beads on a 335/25-20 run flat, and after all that you still need to road force balance, and mount them on the car. And, that's if you don't have to do it all over again to index the tire on the wheel for a lower road force number. Every job you think will be no problem, their is always something to make it difficult, like just trying to get the [censored] wheels off the car, with swelled up lug nuts, the wheel frozen to the hub, corroded bead seats, wheel covered in mud, filled with tire slime, etc. Or, try and see how fast and cheap you could mount/balance a set of LT325/60-20 load range E tires. About killed me just trying to lift those 95 pound wheels/tires on to the balancer, plus they ate up about 4 pounds of expensive lead tape weights, and still have to torque up 32 lug nuts by hand to 150 ft lbs. I'm an online installer with a price quote of $15 on 60 series tires, which just isn't right for a 3 foot tall tire. Not bad on a 195-60-15 tire though. I would make more money if I paid someone to take their tires somewhere else a lot of times.
