Yes I run 4 oz bags in my 32"s. Swear by them. Some people on here are against them but when I get snow/mud packed in wheel it is fine due to the beads rebalanceing constantly. No need to balance for the life of the tire. I have worked in a tire shop for years and use balance bags every day. Mine cost $2.00 per bag, whare else can you get a lifetime balance for $8???
