metric tire sizes?

Postby shawnee1952 » Tue Jul 24, 2012 7:41 pm



I have been cruizing the internet looking for tires for my 77 and find most of them are listed with metric sizes. Not being fluent in metric conversions, just what the heck am I looking at? Also, most tires are now tubeless and I don't want to give up my old wire spoke wheels. Can I put a tube in a "tubeless "tire? Any suggestions and advice are deeply appreciated. Thanks

Yes, tubes work just fine in a tubeless tire. One issue to note is that fixing a flat in a tube within a tubeless tire can be a pain, as you must break the tubeless bead on the rim and that can be impossible on the side of the road without a proper bead break tool.

Your rear can be a 130 90 17 MC, but 120 90 17 MC is closer to stock.

Your front can be 100 90 19 MC and be close to stock.
