I took my wife's freshly power coated OEM alloys and new Falken Winter tyres to be fitted today.

The tyres simply wouldn't seat (pop) onto the wheels after having them on and off a couple of times and coating everything in the lubricant they resorted to pumping them up to 120psi.

As the tyre didn't explode and there is no obvious damage am I correct in assuming no damage has been done ?

I've seen Max Seating Pressure before at 75 and 85 psi.

These winter tyres just have Max Pressure 40psi on them.

It seems they regularly hit 100psi but were getting worried over that.

Though one fitter said he'd gone to 150psi (max of the compressor) earlier in the week.

In fairness at 100psi they got the manager and they had removed and re lubed the wheels already.

He then said to me that the only way he knew was to increase the pressure but it was at my risk as I'd taken the tyres into them (they take the risk if they supply the tyres)
