When I finally skidded the bike to a stop, one of the horizontal strands was pushing the front fender down on the front tire. Lesson learned; slow down even when the gate looks open!

Although there are greater forces on the front tire while braking, I believe the continuous rotational forces on the rear wheel are more likely to turn the tire on the rim. Perhaps dipping below 16psi will change that?
All I'm saying is that I believe in running beadlocks front and rear with tires being run at low pressures. Beadlocks are cheap insurance against pulling a valvestem out of the tube.

Hi Mike!
18 psi seemed ok to me too. Slippage noticed at 15psi.
With the MT21 which has a very flexible casing I have gone as low as 10 psi with beadlocks.
Other tires on other bikes I have gone as low as 5psi with beadlocks. Once on a Yokohama Superdigger I went 30 miles with a flat and didn't know.

I run beadlocks on my front too. Under heavy braking you can get the rim to slip in the front tire at 15 psi too. Your brakes are more powerful than your engine. You can stop much faster than you can accelerate. The front does 80% of the stopping under heavy braking.

justjeff I have now installed rim locks in my 2003 as well as my 2011, no double wall rims found. It certainly gives me "peace of mind" to have the rimlocks installed while I am running low pressures!

PNWcrazymike I finally picked up a rim lock for the rear tire but wanted to wait for my next tire change to install it. I enjoyed a 750mile 4-day weekend and a hard 500 mile 2-day weekend (all off road) so I'm ordering more MT21's for Friday. The front MT21 is pretty rounded off and cupped and the rear has less than 1/8" center knobs. I'll let you know how the rimlock installs.

I was down at 12psi and pulled the valve stem out, on the highway, at 60mph. I managed to direct it to the right ditch,at full lock into the slide, before laying it down. Much better than going into the opposing lane as it was during a high traffic time.
Whoever told you about the double wall rims obviously was "mistaken".

My local shop may have not been familiar with these rims when they told me I couldn't install a LiteLock. If they ARE double walled I'll drill out the interior wall larger than the exterior wall and insert an aluminum bushing, then tig weld it into place. Ill do my best to keep the heat to a minimum so that only the material around the new rim lick hole will be annealed (softer)
Hi Mike!
Hmmm... I'll be thunkin they're mistookin'!! I bought my 2011 new, no double wall. I haven't taken the tire off my 2003 yet so I can't say for sure but....
