245/40WR18 and the 285/35ZR18's on the sumitomo's. they might be cheap but i am really surprised with them. then again the 730's are great also. so are the pzero's. treadwear on the sumi's is 220 and i am not sure what the others are. the only thing that sucks about them are the sizes as you have found out. its really a toss up imho.
