my Hardrock Sport (HRS) came with alexrims 26" rims with the nomenclature of 599 X 22 6061 - T6 on the sticker. the guy at the LBS shop sold me a set of "the same rims, laced to stock HR Disk hubs." it turns out, these rims are marked 599 X 18 6061 - T6. the only reason i got the same rim with a disk hub is because i have never had to true these wheels after i got them set. will this 4mm difference make the wheel weaker? will i still be able to mount my 2.1 width tires? should i re-lace my 22mm wide rims to the new hubs, or what?
