Yeah back when I had my repair shop. I bought a bunch and resold them at basically my cost. Wishing I would have kept some. But I had sold both the snow tracks I had. I did not foresee buying more. Live and learn. Lol. I was hoping somebody knew where there were five or six. Small tires. I could purchase. The large tires are not as bad as the bombardier tires work for those.there was a run of tires. they are all distributed many came to north america, a FF member here made it happen. I was able to source 30 tires from MN outdoors 5 years ago or so. I am not selling as I need more for my collection of weasels. I do know there are others hoarding tires as well, the T522 tires are around. I may be able to share some usable spares........
I bought 8 of these: SKU: TK70918693 4.00-4/2.50 Rib Trelleborg Black Kargo Rubber Kargo Solid Pneumatic (2.50 Standard Rim) from Cascadia Tire in Burnaby B.C. They were very helpful.
Because they are 2.5" wide, I had to buy eight new wheels from Carefree Tire in California: 4" x 2.50", 3 Piece Rim - WHITE Color FOR SOLID TIRES W2162-41212
