I occasionally get a few tires that will not " snap" on to the bead. It is almost always low profile winter tires, on wide rims.
I just mounted a set of China snow tires for a local autocrosser . I mounted them Monday morning, and aired them up to 75 psi , which is usually right at where I start to feel uncomfortable. One tire popped on, but the other 3 would not . I set the car next to the heater for the day, and one more popped, bu the other two would not go.
I aired them up to 100 psi and left the furnace on over night in the shop. I was hoping to come in and find them on , but no luck. It was getting late in the day, yesterday , and I really wanted to deliver this car back to Chris, so I got brave, and aired them up to 120. This is waaaaay past my comfort zone. they still did not pop. I tried driving the car, beating on the sidewall with a mallet airing up and down, and nada. I use tire paste, and they were lubed up very well, rim , and tire
I finally gave up and set the turbo heater 3 inches away from the trouble area on the tire, and within a few minutes each, the other two finally went .
My local tire vendor says they stop at 100. I wonder how much pressure a passenger tire can handle before it explodes ?
I was very careful to keep myself out of the line of fire while this was going on. I have seen a tire explode and leave the tire machine before and I want to be nowhere near that nonsense.
