quote Originally posted by theogre: May not technically require a cages for "simple" rims... state or insurance rules may still require them for any high pressure tires even if OSHA doesn't bother. Go & ask many Tire & other stores. I have over the years & most Will Not mount them including brand new ones. "simple" rims can fail or more likely a default tire can fail when you set the beads. I've worked @ many car & tire shops & See it happen more then 1 time just on 30psi & good that old Atlas machine held down the rim. Setting beads even on 20-30PSI tires on "simple" steel rims has hurt or kill many people. Even MTD had Recall for Snow Blower Tires run ~ 15-20psi max because plastic rim failed & hurt enough people for CPSC involvement. (Bet many way over inflate the very small tire using unregulated or high pressure output from a compressor.)

First off, I work at a garage, and 60psi is not high pressure. Many pickup trucks have 60-80, maybe higher. Tire cages are never used on consumer one piece rims, at least where I live. Tire cages are usually used on commercial wheels, multi piece rim or not, as those are aired up to over 100psi, yes any rim/tire can fail, but tire cages don't even exist in my garage for anything that is less then 2 feet wide, we were inflating a tiny little forklift tire the other day, and we put one of the legs of the lift over it and lowered it into the wheel. Like people have said, shops may not want to do a spare for insurance purposes, as it is emergency equipment, and as it is already a compromise to drive on it, a spare tire blowout would have much worse consequences then a normal tire blowout, as the car is already slightly off balance and tire is much thinner. Also if "many tire stores" refuse to work on cars with TPMS, there would be no tire stores, because every vehicle since 2008 came with TPMS, that's a lot of people who can't get their tires changed in the winter. Tire shops don't ask over the phone "do you have TPMS" when you schedule an appointment, they remove the wheels, and when the pop the first bead they say to their co-workers whether there is TPMS. If there is, they are extra careful, if there isn't, they go on with it. The only way a shop will find out if there is TPMS, is by opening the tire, they could scan it, or look carefully at the valves stems, but to do that would use up more time then it's worth, especially since they aren't going to refuse the customer if it does have TPMS. If you have ever been to a shop that refused to service your vehicle because it has TPMS, they are not qualified to do anything or give you any information, including about tire cages
