rwd ftmfw, i was going to say rolling radius but last time i said that to someone they wanted a full explanation and wanted to know how to solve it with getting different tyres, i spent the best part of 2 days hunting the net for a calculator to get him the sizes he needed only for him to say, "oh i sold em yesterday pal" so sorry for tarring you with the same brush but you never know how much other people know about these things until you mention it, glad i didn't have to go through all the jazz i did with the last person lol
now i've said that someone else will probaby pop up asking, as for what to do with them, you can buy a self alloy repair kit that has all the fillers and stuff to fix kerbing, as a cheap turnaround it may be worth trying that if your going to sell them on, also the VW scene are always wanting rare wheels and although most vag cars are 4x100, 5x100 and 5x112 there are so many owners running adapters so they can put porsche wheels (5x130) on a mk2 golf (4x100) so theres a massive market in that area for you, and the afore mention wheel whores is a great place to sell for silly money too
