lol, i said to heck with it...
i'm running the original 275/65/R18's... i've got 47000 kms on em and i can barely make out the tread on the (now) fronts. last winter was a bit tough on em. but all in all, i put a total of 2 winters and many of those kms were going south from central alberta to southern bc.
my next set are gonna be BFG's AT.
