i hope they do better alignments than tire balancing. they came highly reccomended for large tires from lynn at 4 wheeling of raleigh, so i had them do a set of 40's for me 3-4 years ago. i payed a good chunk of change, and they were TERRIBLE. i could hardly drive the truck over 35-40mph. undid their balancing, threw in a bunch of bb's, and they were ten times better.
i complained, and was basically told tough luck, we can't stand behind our work with off road tires (after the shop jockey told me they'd ride like a cadillac
). i called back again after my bb results, and was still told tough luck (with an attitude that time).
hopefully things have changed since then.
