Key word mounting.... I will beat around the bush here a little since it is so dead on the forum. I had purchased some AR's early in 2013. While feeling well enough to mount up some tires, I dismounted 4 sets of BFG's from Bassett rims and one set of BFG's from the cheap chrome rims I have. Mounted 3 AR's on chrome rims and aired them down after seating the beads. Then came the bead lock rim. slipped a 72 inch tire over it, aired it up to set the beads, checked the air pressure and it was at 30 pounds. Regardless, I had strained one of the cancer spots in my colon and went into severe convulsions of the internal variety from the excessive blood build up inside, and hustled into the house. 3 months later after simply doing minor things here and there, I needed to move that Legends chassis and went to mount the Ar's on it. All the tires had air pressures of 4 to 10 in them except the right rear that I was mounting when I went down. For kicks I measured the stagger change. It had grown to 74 1/4" after being heat cycled from the summer temps and the 30 pounds of air. Chuckled and thought to myself "This will be a tire to cure one of them rev limiter nights ". (on my sprint with Hoosier or AR's I used to stagger tires with this simple meathod)
Basically that is why I asked how much those tires of yours, with 50 races on them, had grown after heat cycling... evidently you are running heavier right side weight in your set-up and the aired down left sides confirms not a lot of weight transfer on the left and coolness if those tires never grew from heat..LOL you dont have an issue of pushing up towards the wall coming off of corners do ya ?? (reminds me, I should pick up 3 or 4 more sets of Legends AR's)
Thanks dude.... peace out and ttyl..
