Hi, I'm having problems when using my bike for bikepacking trips fully loaded 30kg + me at 80kg, while riding the tyre loses pressure and the rim is covered in sealant where it's leaking, this doesn't happen when I riding unladen. I'm running Stans rims which say max is 40 psi, I'm also running Maxxis Ikon 2.2 which say max 60 psi, I need to run at least 60psi to maintain the shape of the tyre and stop the rim from hitting. I really don't want to run tubes and my Hope hubs are bomb proof so wanna keep them if possible, so I guess i'm gonna have to change rims, so any suggestions please?
I don't have experience with your particular tire, but I think this is pretty clearly a problem with the tire. Out of spec/defective maybe? Many tires will seat and hold air without any sealant at all, and not leak or burp at low pressures.
Try pumping the tire up at the lower pressure and then see if you have any leaks. You probably could check for leaks with a soap slurry or dunking it in the bath tub. Just wait until the wife or GF is away though. 😃
Hi thanks for your replies,when I ride at 35-40 psi unladen the tyre is fine, the rim is the Stans flow ex and the sealant is Stans no leaks ;-) I had the same problem with the Conti trail king last year on the Tour Divide, so I think the tyre is fine it's just the rim can't take the load, just looking for a recommendation for a rim that will take a 2.1 tyre and 60 psi of pressure. Thanks
