Still have the original tires that came on my Ace 570, and they are pretty worn. Since much of my travel is on either asphalt or dry hard pack trail, I am thinking of a heavy duty 8 ply tire that is larger and will last a lot longer than the stock 25", as well as be more resistant to punctures.. Anyone have opinions on the 27 Terrabite, and how suitable it would be for the Ace? Is 27x9-12 workable with stock wheels? Would appreciate any helpful advice.
