Honda snowblower complaint center
The tires are good. Don't hold air.
There is a high possibility that the tires may have a hole that could be leaking out the air. You can have a mechanic take a look at it to be able to fix it for you. You may also contact Honda at http://powerequipment.honda.com/snowblowers.
