Wouldn't make anywhere near £350.this is a shot in the dark, but i'd say 150-350. I don't know the tire you speak of.
really, tires that cheap? or cav slabs that regular in UK. all the crap I see on ebay.fr are overpriced i guess.Wouldn't make anywhere near £350.
My guess would be between £80-£120.
If the tyres are as new as you say they are. Then £150-£200 (that being on the high)
