This is a follow up to my earlier thread: Screw in Rear Tire - Advice Please - Harley Davidson Community Had the new rear tire put on today and had a nice discussion with the owner, who's been doing motorcycle tires for 15 years. He said the only issues with putting a tube into a tubeless tire were: 1) If you get another puncture that gets through to the tube, you cannot make a roadside repair (plug and go) and must call for a tow. 2) Slight increase in tire temperature - something about an inner liner on the tubeless tire - but nothing so significant to affect handling or wear. I brought up the issue of potential cord damage as the reason I was replacing the tire instead of having the tube installed. He said if it was only a screw or nail causing a small, straight puncture that cord damage is not an issue. Something larger like a bolt or anything causing a CUT vs. a puncture would be definite reason to replace the tire. Something to think about if you seem to be jinxed like me and find a screw in the road every 2500 miles or so.
