Old school BMX style Cheng Shin knobbies for sale. These C183 knobby tyres were standard equipment on many vintage BMX bikes. This pair of tyres is a fat and a skinny so that means one 20 x 2.125 and one 20 x 1.75.
These fit 20″ x 2.125 rims and as many of the older steel rims were 20 x 2.125 size there is no problem mounting the skinnier tyre. Even says on the black sidewall that the 1.75 will fit on the 2.125 rim!
A sold tyre and great for doing skids just like back in the day.
