Flat spotted tyres.

[Steve McF]

If you have a car parked in the garage for a few months, is there a good way to fix flat spots on the tyres?

My son's car got stuck in the garage once our building work started and a skip was dropped outside the garage door.

The car is SORNed, but the skips have been there far longer than we anticipated. The tyres are all good/reasonably new, and we have tried to move the car about whilst it has been in there so it wasn't sitting on the same patch continuously.

The tyres should recover if they are not abused when first driven.  Alternatively you could pump them up to a much higher pressure to reduce the size of the contact patch, as long as you reduce it before getting it back on the road.

It depends a bit on the age of the tyres.  There’s a date stamp on the side. Four digits. First two are the week. Followed by two for the year.  10 years is considered the life of the tyre in normal circumstances.

As Will says, pump them up to the max and they should be fine; and you say, rolling the wheels even a few inches and changing the contact patch will help. If you're really worried then of course you can always jack each corner up and rotate the wheel, and/or then lower it onto some foam matting.

Pump the tyres up above normal pressure and they should be OK

Let them deflate & be flat against the floor and there will likely be a permanent vibration in the future
