mud tire on a car w/ 1.5" drop?
I was looking for a cheap tire to stud the other day, and found a couple truck tires in 195/65/16.
It's got a 26.1" diameter, as opposed to stock 24.9, so I'm not sure what fitment would be like.
If you want a real off-road tire, your best bet is to find some 15" rims and get rally tires.
