Putting new tires on, can't find inner tubes

Ok, as we speak my bike is in the shop, and I can't find inner tubes for my new tires. the front is 90/90x19 and the rear is 130/90x16. any help?

The mechanic told me i could eliminate the inner tubes by buying a certain kind of valves, but i don;t know if thats a good idea. Let me know, i'm not sure what the best route is here.

Thanks

Any bike shop should have inner tubes You can find them all over ebay for cheap.

the only bike shop around me only had the front. I'm really curious about the valve stems. whether or not that is a bad idea


This is what he says i need.

It look's to me that the valve stem's in your link are for tubless tire's.

My 82 DOHC run's tubless.

Otherwise, most tube's will fit a number of different size tire's as long as they are the same actual diameter size ie 18" or 19" or 21"

The wheel will say if it is tubeless. If it doesn't say tubeless it isn't tubeless. Just buy a tube. I wouldn't want to gamble with the wheel holding air when it isn't designed to.

Most shops generally carry a huge variety of tubes because they service a lot of dirt bikes. If you're having problems consider shopping around. If I was a shop owner or whatever I would be concerned with liability when doing a conversion like that.

Do the tires right. It's what keeps you on the road.
