High-quality, high-performance tires at a very affordable price. I converted an old stainless steel frame plastic rim fertilizer cart into a cart for my canoe, except the tires were old, cracked and leaking. I bought these tires to keep my investment low. They are tubeless, but I went with tubes. They weren't easy to mount, but that's not due to the tires as they're heavy and should last a very long time with proper care.
