Tyre pressure monitoring system

[wildebus]

I had the cheap ones, and they worked okay. But a couple seized onto the tyre valve and had to be carefully cut off. So not using them now.

Little tip on if the valve cap or sensor gets seized on a valve stem ... a Dremel is perfect for removing.
You use the Dremel to make a little slot indent on the cap - can do this on the top or side. Only needs to be around a mm or so deep. And then use a slotted screwdriver to put in the cut and twist and it will open up and free itself off the valve thread.

Are these the ones that work from the dust cap replacement?

While 80psi is recommended by van manufacturers, it might be worth finding out what tyre manufacturers recommend.
Mine were 80psi all round, recent 4 new boots, and 65 rears and 55 fronts. Michelin cross climate campers. They do charts for weight and pressure as I'm sure other manufacturers will.
I know, reopening an old can of worms.

I run the Michelin Agilis Winter Tyres at 75psi rears and 65psi fronts with 2000kg 1650kg axle limits respectively and 3500kg overall weight

Had them sorted last year, said nothing wrong, i think its bead leak, i used to fit tyres for a living many moons back.

Bead leeks can usually be sorted. Could be rust on bead not so easy on slloys

I had a very slow pressure loss on one of my car tyres and it was due to a loss around the bead. No identifiable reason why - I kinda guess must have been a pothole disturbed the tyre on the rim slightly?
Had it sorted, but found there was still a slight loss. Tyre place took it off and redid and been fine since (fixed in August).
