I couldn't resist. Zoom in on this.
All you got to do is curb them 315 80s once or twice and they separate enough, any truck tire for that matter. You combine that with these buses with 16 and 17000 pound front axles, 90° Plus outside, 70 mile an hour and that's how a 315 80 with a recent date code goes boom. Any pair of these variables will do it, that's what I think. Stay away from the curbs, very important.
