Yea like said a thousand times, as any tire and rim can be dangerous, these ring types are not , the outlawed old ones that we do not use are very dangerous, with that said anyone can make anything dangerous, just watch the video, yeesh, Now for as many years as the Military has been on the road, the soldiers have been changing tires on and off rims on and off road conditions, there has NEVER been a rash of injurys . because it is really simple to do, and like above tire and rim show, they do not come off easy at all....Heck an NDT CC can run at 15 #s pressure loaded and go thru the roughest terain, and any other tire and rim set up can only be jealous unless its a specialty tire and rim ....NDTs have more than proven themselves as the set up that is/was amazing for all they did and do.... I really do not think any other set up has the amount of tested time to even compare.....Randy
