i bought 2 used p235 75 15 if i put this in the front on my 94 e150 will it tear them up or would it be better on the rear? right now i have the p235 75 15 on the rear and on the front i got a 235 75 15 LT. i do put a load in the van but dont know how the p235 75 15 will hold up on the rear with a load. its not a real heavy load its just some weight in it to make the rear sag down. thanks
