Cooper Tyres Loosing Air

[Phoenix]

Quick question Since i change to Coopers i have noticed that after every drive (almost) in my way home some of my tires keep loosing air. The next day when i go to check the tires some are complete flat when i inflate though they are ok until the next time that i drive and again i face the same problem any ideas

i never had this problem with the Geos

the coopers are great i have no issues with the grip

is there such a thing that the rims may be the problem

Go get them all cleaned and valves changed

So get them taken off, cleaned, rims cleaned and put new valves

One other thing I noticed is that the powertank attachment we use pushes the pin in and it sometimes sticks, letting air out.

Very rarely i have this problem with my geos too. Once in every 10 drives

What i have started doing after every drive now is loosening my valves and tightening them again to let any sand out. Need to get valve caps again

I'm using Cooper AT3 since long and never had this problem. however I remove the pins when deflate and inflate

Had the same issue once and this worked out ... sometimes the sand finds its way between the tire edge and the rim and starts leaking air.

Had the same with sand between tires and rim, as told above.
Even without a popout this might happen.

But I would also have some spare pin so if one of them is leaking, or you lose one of them, just change it.

You can get some, usually for free, when doing the tire cleaning. Just ask the workers for some of it.

I would do the same. Also I would check the rim because it is might be bent!!!
