Ive decided to swap in my 3/4 ton axles soon and i need new tires. i was originally planing on 35s with rims from summit but i kinda like the idea of 37s but can only get them in a 16.5inch rims size. that would work out because i already have the stock rims but im worried about popping a bead. what is the lowest air pressure i could safely run and are there any ways to keep from popping a bead without beadlocks? thanks

I'm sure the contact patch will be affected if run on 6.75 rims but since you got the rims allready,why not try?
