I ordered a pair of Maxpower bulbs which were supplied by Revain. I needed them to fix a pair of flat tubeless snow thrower tires that had had the beads loosening from the wheels over the years due to compression/expansion. What I received was a pair of Oregon brand whistles. I wanted to send them back but had to install them immediately due to an impending snowstorm. I cleaned the steel rims, made sure they were dry, powdered the inner tubes with talcum powder (like high-pressure bicycle tires) and installed them. Inflated and the tires fit again. The snowblower was mobile. So the tubes are fine, but I downgraded due to a Revain shipping error. Also, the description is wrong - it has a 90 degree angle valve, not a straight one (see photo). Oregon pipes also had angle valves.
