Our class doesn't allow bead locks. Any ideas for keeping the RR tire on the rim? I run g60-15 AR's with 8" aero wheels and tubes. If I get much below 14psi an catch a rut the tires pops off.
I was think of trying windshield urethane. Anybody try this? Any "stealth" bead locks avaiable.

dont run less than 14 will be the best deal.
most chassis places that are really good will still only recomend about 12-14 in the right rear anyways.
just keep it over 14. i run 15 in my mod on rough tracks.

We can run beadlocks on the RR only. On all the other wheels I weld a bead "across" the rim which bites into the tire. Weld about six or seven "L" shaped beads around the rim I use weatherstrip adhesive to also glue the tire in place. I also run tubes. Never seem to have flats or tire issues. Try to keep the pressures up if you can.

less than 14 psi = faster lap times. The easy way out is to run higher pressures. I need to run in the 10-12 range. What orientation are the L shaped welds?

or....you could put a arkansas beadlock in there. use 1/4" round stock. what you do is mount the tire and seat the beads. break the back side bead loose. reach in there and tack weld the 1/4" round up against the bead inside. dont get it too hot or the paint will bubble.

I usually run 18-22 pounds of air in the right rear.......actuall, I run about that in all the tires.

L-shaped welds go across the rim under the bead of the tire and then continue along the rim bead "hump" about 3/4 of an inch. This builds up the bead "hump" of the rim some but not making it difficult to mount and seat the tire. Also use black weatherstrip adhesive to "glue" the tire in place. Works for me.

weld 5 bolts to the inside of the wheel then get some 1/4" cold roll it to fit the wheel and then weld some sloted clips to the cold roll makes sure they match where you weld your bolt to your wheel set the tire on the bead break the back side back off then slide the ring with the sloted clip over the bolts and tighten the nuts down so that the clips that where welded to the 1/4" cold roll hold . i may have to email you a pic of this it hard to explain srry

When mounting the tire, use a little superglue on the tire. Works wonders.

Sounds like the result of other issues, I would work on your chassis setup and not the tire and wheel. At that pressure you have basically no sidewall, so the rim digs and you blow the tire. It is NOT the tire or wheel. Mask that problem and the REAL issue will surface, or another and so on.

Racerguy - the tire and wheel combination we run is the same as the imca mods. They can run a beadlock. They typically run the rr tire down to 10 psi with the bead lock. We are running lots of power to a very small tire so any gains we can get as far as bite goes will help me get on the throttle sooner. Through much testing, I have found better bite using less that 14, but if the track gets rutted up the tire will come off the bead. We can tune wegdge, springs and shocks till we are blue in the face (which we do). But lowering the RR tire pressure makes the car get off the corner faster and lap ties prove it.
