Although wheelbarrow tyres are a good size, the walls of the tubes are very thick. Thin walls are better. A child's bicycle?
They may be a bit too thick. They are a good size if you have a unit that has very uneven weight distrobution and several tubes are needed, like some tube amps where all the iron is on the back of the amp or in my case a Well Tempered Labs table with the motor encased in a 12 lb.lead brick. It seems to work ok with the three tubes so far but my plan is to add a very high mass of sand between the table and the inner tubes. This might be able to negate some of the tubes thickness factor. Then again it may not. Any thoughts?
I have to say the best thing I have done so far for the sound of my table was to decouple my sub from my plywood floor. It was getting bombarded with vibration coming up through the floor. It helped everything in my system.

That's what I've had good success with. 18" x 1.75" inner tubes from a child's bicycle.
