I don't know how you guys manage to loose it? I had my original caps until 194934 miles on my escalade hybrid with 22's until I traded it for the new platinum.hunterp27 said:you aren't doing anything wrong. you are just suffering thru one of the poorest designs in modern day wheels. the design sucks, the materials suck, the whole scenario is simply shoddy. right now i am trying an aftermarket set that look identical from the outside, but inside they do not have the metal tension rings. The just have plastic tabs that seem to be built a tad bit better. long term report forthcoming. had them for about 2 months now and bought them on ebay. set of 4 for 90 bucks........so far, none have flown off like a frisbee while driving. i still cannot believe these were 80k trucks new. i'd be so angry with myself if i'd bought my truck new. the quality, fit and workmanship is terrible. i love the looks and utilitarian capability, but i swear i am wrenching something one a month.
