Technically speaking, the number 325 is the tread width in mm. Conversion to inches is 26.5mm/inch and you get ~12.26xxxx
The the 50 means that half of the tread width (50%) will be the sidewall..
From the MickeyThompsontires.com site:
3757R P325/50R15 (28x13.50R15)
3762R P295/65R15 (30x12.50R15)
3763R P315/60R15 (30x13.50R15)

Looks like its going to be fun making em fit-I'll probably end up with a bit more (7/16") spacer and a big hammer inside the wheel well...if you get em first let me know how it works out...
I'll post pics if I happen to run across a set...at $320-350/pair I'm not going to be too keen on any rubbing going on back there...
