look chaps , I don`t know if you are saying winter tyres wear out quick in summer because someone told you that . I doubt if you have proven your statements through personal experience because I have a 7 series on Pirrelli snowsport tyres for 20000 miles they have never been off the car , they have driven for 750 miles on mostly motorway on one continuous journey at high speed with a fully loaded car in summer time at 30 c temps and they still have 3mm tread on them at 6 years old .
I have a X3 with Avon Ranger Ice tyres , tootles around country roads all year , has covered 15000 miles on those tyres and they are stiil at 7mm .
so who is right and who is wrong in this debate .
drive like a nutter on winter tyres and they wiil squeal round corners but you can still move along at a fair pace with them , try it out and come back and tell me how they do .
