something else to also bear in mind is are the tyres new or part worn?, as my friend is a manger at a branch of etb (exhausts, tyres and batteires), and its now comapny poilcy that they arent allowed to fit part worn tyres anymore.
something to do with if one exploded and injured them or they fitted on and it failed etc whilst the customer was driving, they didnt want to be held responsible.
he wouldnt even drop a part worn on for me when i need one on my gfriends car when we were selling it
