I fancy fitting 195/50/15 tyres to the lads Avon, anyone know what offset I should look for, to fit wheel arches correctly? Anyone know of any bargains to be had for set of FOUR.

standard sierra offset for the avon, ET35 i think, have a look at the adds in fast car magazine there are some good deals to be had in 15" the bigger adds have loads of pics of wheels to choose from (thats where i found mine)
