Thanks for bringing this up, should be mentioned early in any Weinmann Concave thread. The Concave is not a hooked-bead rim, so you're pretty much limited to tire pressures not over 75psi. It that meets your needs, fine, but you should be knowing you are limiting your tire pressure options, and keep in mind that just a pound or two over the limit will greatly encourage blowoffs.
