These are rc4wd 1" Scrambler tires mounted to their Stamped steel beadlock rims. I mounted them on a 1/24 Basher Rocksta, which has servo upgrades and softer springs in it as well. It has 4ws which I was using 100% today.
At first before today I used stock Nylock nuts on axles, and they stayed on tight, and I ran the Scramblers a few times, much better than stock tires. I also when first mounting to beadlocks had cut a channel around the outside perimeter of foams in the center of width, and put 15 grams of BB shot in each front and 7 grams of BB shot in each rear tire.
Today I used new taller axle nuts that worked better with the new rims (tool grips better). But I didn't have locktite on them.
I ran the micro on a new indoor course I had made for it, which although there is a lot of drops, has a lot of friction for the tires to bite into. Has the consistency of 60 grit sandpaper.
So the two changes today were that, new nuts and new course. After only a few minutes at most, I saw a couple of BB on the course and looked at the tires carefully. All four wheels were wobbly on their axles; the nuts had backed off 2-4 turns on each axle.
Worse, the two front tires on the outside only had been cut or ripped away where they clamp to the rim edge. The left tire maybe 60 degree arc around rim was cut; right tire maybe 30 degrees.
AFAIK, no tire cuts on inside of rims, and I'm pretty sure rears are okay, although I'm not ruling out possibility that a small arc may be cut and just won't show itself until it grows larger.
So what caused this?
