these tyres have between 5.5 to 6 mm tread on all tyres . they come off my deceased 2004 Vauxhall astra whose engine has seized.they are this cheap because I would like your old wheels in tyres in exchange so i can take remainder of car for scrap. Its a 1.7cdti astra in case anyone interested. Will exchange less tyres if required.Also have one month old battery as well for £35 in fact anything that you might want from the car if easy to remove!
