I have them in my 33's. I never bothered to remove the weights that were already mounted, maybe I should? Anyhow, at first they created a lot of vibration while slowing down in a curve, kinda freaked me out. Might have been caused by the humidity in the tires after re-inflating them. All this went away after a few days and its been good since. Tread wear seems nice and equal but can't give credit solely to the beads...
I often air down, so I simply ensure the valve is at noon and not at 6... Easy enough. Plus the company I bought from sent me valves with screens but I misplaced them
I won't bother with them again. I like the idea but next time I'll simply use coolant (the one that is safe for animals so no issue if I loose it in the outdoor) and with coolant it doesn't freeze on me!
Cheers
