Since 07, when I bought my tractor, never had a problem with a valve stem braking, until now, on a brand new rear tire. After 600 hrs. I had new tire's put on because on the 4 ply tire, the tread was getting down and one rear tire had a real bad 2" cut in it, and leaking, it was fixed once 4 years ago. When I bought the tractor, I thought some day when I replaced the tire's, I would weld on stem protector's, but never did brake the rear stem, and I haul out my firewood every year and logs, the stem has had sticks hit it before, but the difference now is, my old tire's were tubeless, filled with RimGaurd and had lot stronger valve stems. Now I have tubes in the tires, filled with calcium, and the tube valve stem breaks real easy if a stick hits it.
So to make/weld on valve stem protection, I have to take the tires back off the tractor, take them back out to the tire garage, (30 mi away) dismount, bring the rims back home, take rims back out another $100.00 +, didn't really want to do that. I thought if I look on TBN, I could find someone, anyone, anybody, who made clamp on bolt on valve stem protectors, so I could have some idea what to make, then I came to a conclusion, there's no such animal. So I spent all day last Saturday trying to come up with something, anything, now I have these to test out, I just don't want to take the tire back off, and the moral of the story is, if your putting tubes in the tires, while the tire's are off, weld on stem protectors before the new tire goes on.
