Call it an informal survey, I'm trying to get as many opinions as possible regarding the use of tubes in the RR beadlocks. I ran them for the last 3 years, mostly because my beadlocks would always leak out all the air and it's a real pain to air up a RR with the car in the trailer. But this year I've gone through 4 tubes in the RR, none of which suffered any contact beforehand..they just let go. Went over the wheel with a microscope, no burrs, no problems.. used nothing but the best tubes always, but they still kept busting. I'm running 10 lbs. air there, but I know of another guy who runs 8 there and runs tubes without any trouble. I've gone back to running it tubeless, but would still like your responses.

Thanks,
Matt

Count me in the running without tubes group. The only problem is slow leaks.

I have also seen that some beadlocks that will eat them up. When you roll over in the turns the tire will pinch the tube next to the bead lock, just something else to look at.

I'll never run tubes again. The last time I ran tubes was 1998, while leading three different A features, I had flats, all caused from the tubes getting "pinched" when the car rolled over on the R side, the same as Jammin mentioned, since getting rid of the tubes, I have had only one flat tire in the last 50 races. (Not counting the four flat in the garage every week!!) sixwillwin

I typically don't run tubes unless I have a good tire with a pinhole or cut and then I usually run it on the lf where the tube won't make the tire run hotter. I am glad you mentioned the pinching in the RR beadlock because my brother has been having problems with that and we couldn't figure out why, and I have a tire with three laps on it and a pinhole and it's the perfect size for my rr and I was considering tubing it on my beadlock, hmmm, maybe I'll try it without a beadlock.

The tube is only something else to go wrong when you don't want it to. There are all kinds of sealers for tires out there (implement dealers Farm and Fleet) they will coat the inside of the tire. I personally use ruglyde and clean the beads extremely well before mounting. If they hold the air for the length of the race that's all you need. as for flats in the trailer, put a tire on that corner that holds air before you load the car.

Personally, I despise airing tires up when they go flat in the shop, week in and week out. I guess it is just me, but I think I would do what it takes to make them NOT leak. Whatever that might be. You can call it lazy, but I hate doing work that I don't have to do.

I gotta be with you on this one Jammin, especially having to run without any pit crew to speak of.. Gotta find ways to streamline my preparation practices, but none of those practices are going to do any good if the tire goes flat. Mel hit it right on the head with the idea of changing the RR before loading it, that's what I've been doing. Hadn't thought about the bead sealer idea.. another one staring me in the face that I never thought about using on the race car...wouldn't be the first time. Thanks, Mel!

Try running an inner liner between the tire and the tube ( a thick piece of rubber cut to the size of the rim seems a little crazybut it works
