Yeah, I’m an idiot. I’ve got one of those air compressors that you set the p.s.i, start it up and it automatically stops when it reaches the preset pressure. Well, I either was reading the LCD upside down or the thing didn’t stop or whatever.
Anyway, it was that high for about 4 hours when I realized my mistake and returned it to 35 p.s.i. Is the thing going to shread on me? Did I stress it too much?
Thank ye.
Oh, if it matters it’s a Michelin Cross Terrain. Or XTerrain.
I once saw a program (that pre-dated the little portable compressors that are so common now) that discussed techniques for extreme outback/desert driving. The program suggested that you deliberately inflate your spare tyres (yes, I meant that plural) very high (I can’t remember how high, but certainly 60 psi or maybe even 100) so that after you’d had to lower tyre pressures on your driving wheels to get across very soft sand, you could use your high pressure spare tyres as a reserve for re-inflating the driving wheels.
Which tends to suggest (assuming tyre construction hasn’t changed in the meantime) that you are OK.
Many of the years I drove race cars the rules of the class required we race on street legal tires. I would start with 40 psi in the right front tire and it was not unusual to have tire pressures in the 60 to 75 psi range after a race and we abused the tires in ways they were not designed. I don’t think I ever had a blowout due to the excessive pressure. Other than a little extra wear to the center tread of the tire, you did not hurt it a bit.
