I just installed tires called Semeiqi 26 x 4 on two Rads along with brake jobs. They look fine. Getting them on is tricky because of the packing folds and setting the bead evenly. Put them in the sun for an afternoon, flip and leave them in the sun for another day. Only pressure up to 15 pounds or they will come off the rim the first two weeks. Having a front tire come off the rim is very bad. I know it is the back, just saying. Use caution. I am in Sonoma, Co.
