good 18" rubber will be roughly $250 each, you'll find cheaper if you dont mind a bit more of a 'rough ride' (not too bad though) and a bit of noise. Seems like an OKish price. Just think if you do get the $250ea tyres, with the price of the rims thats $2,333. And does that rim in the picture have a mark on it? or am i just seeing things? If its marked I wouldnt for that price.
my rims are worth about $250 each and they arent special or nething, just bulk shadow chrome csa wheels, these are probably harder 2 find and probably worth the extra money, but i wouldnt buy it now, thats a bit much i think
