I have Tyron bands on my wheels as a safety precaution but what a hassle they are when it comes to changing the tyres. Even companies recommended by Tyron to change the tyres can't do it or won't do it. We are beginning to regret splashing out £200 on the bands 4 years ago as at the moment I cannot get any one in the Worcestershire area to change the tyres, that is remove the wheels or alloys from the caravan and then change them!
