HOw soft is your rim

Dear all,

I hit a little piece of rock on the road that bented my front rim in a way I had to replace it. Seem to be very soft metal. Anyone same experiences?

I drove about 120 kmh and ran over it. Did not even feel that hard but it damaged both rim and tyre. Costs, total euro 650.

soft rim

BMW rims are made soft to lessen the impact in a crash or other. the logic is, that a rim is cheaper than a front end or bent triple clamp. been that way for a while now. sorry about the rim, don

Unhappy

Salt Lake BMW noticed my front rim was bent when they installed new tire at CCR 05. No one had noticed during two previous tire changes?

I did hit a chuck-hole 2 yrs ago when still on first set of tires hard enough to get the big "CLUNK" and knock loose a mirror. Pulled over and reinstalled mirror, checked tire and rode on. Now I know it is bent but can not feel any negative feed back at any speed.

Ignorance was bliss;

It's soft so it bends, rather than fracturing and causing sudden deflation. Could they be more rigid? Yep. Nonetheless, I prefer the design choice BMW made (i.e., erring on the safe side).

I've heard that if you keep the tire pressures near the maximum, it lessens the chance of bending a rim.

Higher pressure not neccessarily the answer

I run 46 psi front and 50 psi rear. I have recently had to replace a rim on my 05 LT with just over 68,000 miles on it. Was starting to notice some shake at around 40-45 mph. I believe that even with higher than recommended pressures a hard enough bump to remove one mirror may still bend a rim.

The wheels are easily straightened by a professional. There are several places in the US that specialize in straightening motorcycle wheels, especially BMW wheels (because they need it more often!). I've had it done before, no problems. Fortunately, haven't needed it on my current bike.
