Got a pair of Ukai 20 x 1.5 rims. Comp 3 20 x 1.75 tyres fit the rims okay I am told but struggling with inner tubes. Got a couple of old 20 x 1.75/2 knocking about but cant get the blighters on the wheels and then for the tyres over the top.
Am I going to need to get 20 x 1 1/8 tubes?
Thanks in advance.
