Stretch tyres loosing air

Post by mk2fanatic »

Hi guys, I have set of stretch tyres on a brand new set of rims however I have a problem with them loosing air regularly. Is this common ? Is there anything I can do to remedy the problem, this is really becoming quiet irritating, contemplating buying a new set of normal tyres if I can’t sort out the problem

size of tyre and width of wheel? also what make of tyre?

You generally have to run a higher pressure in the tyre when running stretch to keep the sidewall seated but some tyres have stiffer sidewalls and others less so sometimes it's not needed.

Depends how much stretch as well.

Look and see where the leaks are, some tyre shops damage the bead when fitting tyres and creates small leaks.

Answered your own question..... also what is "set of stretch tyres"? Specially made stretch tyres or just tyres incorrectly fitted?

Heyy .. The tire size is 185-35-17 on a 7j rim

When you say higher pressure, how much would be correct ?

Definitely shouldn't leak unless pressure is already too low or wheel or tyre is damaged. I'm running 165/50r15 on a 7j, but pumped to 2.4 bar.

I've never had issues with my 'stretched' tyres but they aren't that stretched in my opinion and I always run higher pressures in them.

I ran my 205/40/17 on a 8.25j on 2.6bar front and 2.4bar back. Never had any issues

Damaged bead when fitting more than likely. Had a few cases of this myself. Strip tyres and inspect inner bead wall......If not then tyre sealant and up the bar a bit.
