My bike is a 25 year old panasonic steel frame with a 80cc HT motor on it with 27 x 1 3/8" tires. I weigh about 215, the HT motor about 25lbs and the steel bike itself is not light. I am frustrated with flats on the rear. The last thing I tried was the old tire inside of a new tire for double thickness which worked for a while.
I was riding a few days ago when I heard that dreaded firecracker sound and the rear tire blew. I don't think I hit a hazard but I may have inadvertently put too much air in it. My front tire is at least 25 years old with no problems. However I've been through 5-7 flats since I built the bike last year on the rear tire. I've had mystery flats, snake bites and blow outs, one from a hole in the pavement.
Recommended tire pressure for the rear is 90 lbs. I put it there to avoid snake bites.
When the last blow out came I just slowed way down and coasted the last 1/4 mile home down a hill. I noticed the tire beads were completely outside the rim on both sides when I got back. I'm guessing that might happen riding on a flat to any tire or does it indicate anything?
I came across the Armadillo tires and am thinking of putting them on or possibly a solid tire. Is this wheel size just to narrow to expect good tire life?
I have been scouring the threads here and the Armadillos seem to get good reviews. Some solid tires seem to get mixed reviews and I assume are a bi-atch to put on or get off.
The roads can be pretty rough here in Brattleboro, VT and I hesitate to go any significant distance on this bike.
Any help would be appreciated, esp. opinions about tire size for this bike.
Under inflation vs full inflation?
Similar size bike results?
Thanks
