Thanks guys....been refurbishing my '92 RC10 stealth and, wanting to reuse the original wheels, needed to get the old Losi X patterns off. So, got some acetone put just a small amount in a sealable tub with a pair of wheels. Left for two days and the tyres come straight off, the rims cleaned with a little of the acetone on a cloth and rims as good as new.!
Yes I know the glue was 25 years old but the tyres were still well stuck..
Never removed old tyres before but will not hesitate again.
