Yooper has a good suggestion...but I don't think there are too many Gator owners on TBN.
As far as "eating front tires", what do you mean? Overall wear? Wear on the outer or inner part of the tread?
Pictures would be handy.
Normally, overall wear indicates low tire pressure...wear on the outer or inner part of the tread could be toe-in, toe-out or camber.
