I build my own wheels and prefer to stress relieve them during truing by driving my Hummer H 1 over them. They have survived this and they are indestructible. They must be the best out there. I would be willing to sell sets for $24,000, but remember this includes latex tubes and nano thickness tires. Wheel quality is best measured by the force used to build or test them. I will have a video out shortly but I have to have the Hummer repaired because I backed over it with my D 8 Cat doing testing on the strength of the Hummer and it was damaged. I also unfortunately threw a track off the D 8 and it is being repaired as I write this. These testing procedures are certainly more expensive that I thought they would or should be!
