Reviews
Excellent product and appreciated FedEx overnight shipping.
Mounted and ready to go. Weather permitting they will get a testing, but fit, and ease of installation exceeded my expectations.
Great value
These are a true 90 degree valve stem with the valve stem being very near the center of the tube. These tubes work very well for the Azusa 2 piece experimental wheels. The Azusa 2 piece wheel is a split wheel with the with valve stem placement in the middle of the wheel. Meaning that each half of the wheels has a 180 degree cutout for the tube valve stem. A true 90 degree valve stem is required for this application. The rubber thickness is near heavy duty on these tubes as well. Be careful as some tubes that claim they have a 90 degree stem are actually 45 degrees and the stem is offset further tpo the side of the tube.
Nice tires they hold 80 PSI and roll my Bell 206 with ease (ground handling wheels)
100% accuracy regarding description of item. Great shipping time and packaging.
Tubes are okay. The manufacture has changed the model over the years. The latest model has the stem on a slight angle, they tend to rub against the opening in the rim, eventually causing a leak.

Nice little tire, but not very hardy. You get what you pay for..
This tire lasted over 100 landings, so for a cheap $10 tire its been great for the money. The problem I found was when I found that it was a touch low on air pressure on the preflight of last flight I did, maybe 30 lbs instead of 50 lbs, and I mistakenly decided fly it any way. Mistake. Upon post flight inspection, there was a large bald spot on the shoulder of the tire. Hmmm, I like that this tire is light for weight and balance purposes, but Im not so sure Im going to run this tire any longer. Its a bit fragile.
Tube is of good quality, good 90 degree bend but valve is not on center. I also had to modify rim to make them work.
