I'm running the white steel rims from summit part number usw-70-5855 currently this year I've cut the valve stem in 3 out of 7 races. I've ran these same rims for 3 years and ocassionally I've cut a valve stem but never really woried about it but this is getting very frustrating. all three times there has been scuffing on the wheel right where the valve stem would of been so I know It's from contact. Anyone have a way of protecting the valve stem, I'm currently running tubes but all options are open. I currently have 12 wheels so don't really want to change wheels. any suggestions?

Thats the only problem with using those wheels, the valve stem is close to the bead and is angled outward, vs. racing wheels, the stem is inward and pointing straight. Try welding a short piece of 1/2' or 3/4" tubing around the stem to gaurd it.

That was my thought but my primary sponsor ownes a tire store and thinks that is would mess with the balance too much. has anyone tried this?

i wouldn't worry about the balance.ever come in with a big chunk of mud in the wheel?did you notice it out on the speedway?plus,belive it or not,2/3's of those wheels are probley bent,just a little wheel banging will bend wagon wheels.not to worry most of us are running bent wheels ,even if we don't know it.next time under the yellow watch the guy ahead's wheels.you will be suprised.i don't know anybody who balances there wheels on dirt.plus,that little bit of tubing will help you finish the race,i'll take a little "vibration" to be there at the end.

OK everyone is saying basically the same thing I'm saying the weight won't make a differance with the mud and being bent their not balanced anyways. No he does not balance them so there's no weights waiting to be a bullet. He runs superstreet and is able to run racing tires I can't the only other thing we've looked at is running fake beedlocks all the way around which a lot of other racers have good luck with because they protect the valve stems th eonly draw back is their like tripple the cost. I'm just looking for everyone's opinion he's a really really good sponcer not just tires but pretty much anything I need race wise so I'm trying to find a way to fix the problem without ****ing him off.

Do like hanson said, thats what I do except I don't run tubes. It does make it easier on the tube having the hole more towards the center of the wheel.

i used to drill a new hole behind the center of the wheel and the valve stem was accessable through one of the holes in the center and never ever had a stem damaged

We'll the decision has been made were going with fake beadlock for the rear tires and the short metal screw in valve stems for the front were also going to use the black bead sealer on the front's since they won't have tubes. Thanks for all the sugestions.

Racer 17J I'm not real sure if any of what your saying will really help. all the valve stems I'm lost have been from contact. I run the white spoke wheels and I repaint them if they get scuffed up on all three rims there was tire marks on the inside of the rims. what your suggesting would help if I was cutting them by spinning the tubes inside the tires.

Our plan changed were going to go with the fake beadlocks all the way around (my sponsor owens a tire store and was too conserned about running without tubes) just hope I can get thru tonights race as the wheels my sponsor ordered never shipped so were going to have to wait till next week.
