Was just what I need to keep me flying.

The valve stem is exactly 90°. My old one was 45°. So I could not use the new one. Now I have two tubes that I have no use for. But it’s not worth the shipping cost to send them back.

Mounted and ready to go. Weather permitting they will get a testing, but fit, and ease of installation exceeded my expectations.

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 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.
