Title: tubes in K75 wheels?
Post by: mac on June 11, 2013, 12:07:49 PM

Call me crazy (you're crazy!), but I'm looking to put some dual sport tires on the K.

Hard finding options in the right sizes (particularly an 18" front). Some of the better options in terms of size and tread pattern are tube-type tires.

Anyone have any experience running tube-type tires (with tubes) on these wheels?

Its probably okay. the one thing to pay attention to is that you may need long stem tubes.

Thanks to both of ya. I would also think it's OK. I know of people running tubes in tubeless tires as an emergency repair, and continuing for thousands of miles, but some of the fun police make it sound like tubes in tubeless wheels is a death trap. I guess i was hoping for someone to say "I've done it and I'm still here."

TUBES WARNING!!
I hope my experience helps you decide. I have a '91 K75S and got a staple through the back tyre. The tyre was nearly done but still had a bit of life so I decided to fit a tube. A few months and approx. 700 miles later I went to the local garage to check/adjust pressures. Pressure ok so I moved forward to the pumps and BANG - rear tyre blew out. On inspection the valve stem on the tube had sheared where it pokes out through the rim. I had not done anything daft, like leave the airline attached and I've been told that as they are not designed to take tubes a fitted tube can move about under load and possibly caused a fatigue crack in the valve stem. I consider myself a lucky boy because  a few days earlier I had been whizzing down the motorway at 90mph . . . .

Running tubes in a tubeless rim is kinda like dancing with the devil.  You're either gonna have no issues or it'll got ugly at the worst time and the worst place.  I'd suggest you keep looking for a good tubeless option or be prepared to be changing tubes in the middle of nowhere.
