I have another Aeroheat failure story. Back wheel of my recumbent, 20" (406) 32 hole. The rim flared out at the valve hole area. I put it down to running too high pressure in a large (20 X 1.90) Hookworm tire. The tire is rated to 110 psi, but that much pressure in such a large section tire puts a lot of strain on the rim sidewall. I never ran the pressure that high, but obviously too high none the less.
I made it sort of rideable by compressing the rim, but the resulting brake pulsing is unacceptable, so I'll have to replace it.
Thinking it will get a CR18.
