This is the correctly sized inner tube for the 11-400 lamb tire. The Aero Classic tube may NOT be the correct size (eg, too big by ~40%)

Looks like reasonable quality for a good price. Unfortunately I pinched the tube (my fault during installation) so had to throw it out. So cant comment on how well its working or holding up.

fast international delivery

It is what they said is is.

Works

Sidewall punctured at 127 hrs, I initially patched it, but then decided to replace the tire and tube as a set due to the tire having only 10-20% tread left. Not the greatest life but pretty cheap to replace.

Fast service, but delivery was expensive. I would buy my next tubes from aircraftspruce. Excellent company to do business with.

Ive bought numerous front tire and tube sets for my Glasair from Aircraft Spruce. Im really concerned about the most recent tube I purchased. Years ago used to be able to buy a tire with Lamb printed on it. Then those went away and it was Cheng Shin with a Cheng Shin tube. Never had an issue to date. The most recent tube was manufactured in Vietnam, manufactured by somebody called Makuro (or something similar). It is noticeably lighter construction - one ounce lighter (5 7/8 versus 6 7/8). I debated about putting back in the old Cheng Shin tube but decided to put the new one in. It will be a bad day if I ever have a nose tire tube give out on landing. I need to remember to look for a better quality tube on the next change.

Held up for 2yrs, then tore along a seam while in flight. Touched down and had a flat nosewheel.

These tubes seem weak at best, but they are the only ones available in this size
