The tubes are of obvious good quality but do not fit the valve stem hole. The rim is made for tubeless tires so I did not want to drill the hole out to fit the thicker and longer valve stem. If I did the length would interfere with the hub. So I went back to the heavy duty tubes that fit from Tractor Supply.

Replaced tire and inner tube with this new tube. Old one was just too old to keep on flying. Looks like this new one will last a long time too.

Product arrived and worked as expected. Great customer service.

What can I say? I received the usual excellent Aircraft Spruce service. Item was in stock, was shipped the same day, and arrived as expected.

Flawless transaction, as usual. Had a blowout on my nosegear so we decided to replace all the tubes and tires all the way around...I already had the tires in storage but needed tubes. Great packaging, timely service...it arrived when they said it would. A&P got them installed, they work perfectly.

Great tubes.

No issues appears tough

Very happy with them so far. As always Aircraft Spruce was fast on delivery.

Great tube

still holding pressure

I havent installed this one yet. Im carrying it as a spare. The service and shipping were very good. No problems. I thought the price was good too. Thanks Aircraft Spruce!

first tube came damaged in box. they shipped another one, and I had it the next day. no charge. thats great recovery.

Fantastic service.Ordered one day and it was here the next day. This was important since my plane was sitting on the ramp with a flat.

Second time to purchase this product, and I would buy it again. Easy installation.

Real fast service you can count on with AircraftSpruce.

Definitely got the tubes quickly so our students could finish their projects on time. Excellent charts for application data.

Purchased, have not used yet. Arrived quickly. There was a complementary flashlight offered with purchase, but I guess theyre on back order.

The tubes seem to be holding air, which is the main goal. For whatever reason, there was some unexplained ballpoint ink scribbling on one of the tubes near the valve. I cant explain this since it came in a sealed plastic bag. Easy installation. Not as easy to get the valve to accept compressor air (compared to my vehicles.)

The first one had 2 pin holes next to a seam by the valve stem!! I had to have the mechanic redo the installation! Not expected for the price! Then there is the trip to the post office. Spruce very good about the return stamp and sending out a new one quickly... Thank you!

The reason for the three stars is because the valve core on the new tube was leaking after the new tube was installed on the airplane. Thank goodness for the sealing metal valve cap. I put a bit of fuel lube on the valve cap threads to guarantee no leakage.

Ordered tire and tube together. Both were shipped the same day. Tire arrived in two days but the tube took an entire week. Little benefit to fast delivery of the tire. So far the Leakguard tube has yet to demonstrate that it can maintain tire pressure, let alone any significant amount of air pressure. First attempt to preflight indicated 12 pounds of air pressure. Second attempt indicated 8 pounds. Thanks to my leaking Leakguard tube I have missed two flying days already. I’ll try the Michelin brand next time.

My 600-6 TR-20 developed a slow leak after about 1.5 years of use. Looking at the removed tube, there was several square inches of the sidewalk with numerous pits in the rubber, one of which was slowly leaking air. There was no Foreign Object Damage on the tire sidewall. When I removed and replaced the tube with another TR-20, its valve leaked until I placed the metal valve stem cap on with a bit of fuel lube on the threads to guarantee the seal. Had I found the pitting before replacing the tube, I would have looked for a different product as as the replacement. I have closeup photos if interested.
