looking at tires ....can tubless tires be fitted to the old 70s tube tire rims.Thinking of a better tire selection .

motard dudes do some silicone treatment to the area over the nipples to keep them airtight. i have never seen this first hand, but i have seen a lot of motards running tubeless tires.

The tires I run (Dunlop KR825) are tubeless design, I run them with tubes on spoke rims.

Bull,
I am running them on new Excel dirt bike rims though. Not sure about mounting them on the old steel rims. Bead flange on some of those old steel rims is pretty short.

I know cb750 stock rims will take a tubless tire provided you use a tube inside it (the bead is wide enough). Can't speak for other bikes.
