I recently purchased a 2012 Grizzly 550 with about 1800 miles. It currently has almost new Deestone Swampwitch tires (25×8-12 and 25×10-12). I HATE them!!! They aren’t wearing out at all, and they dig into the ground well, but it feels like I’m riding on solid rubber wheels. I slowly let air out of them until they started to give a little, and when I checked the pressure, it was about .5 psi. I think these things are almost run-flats……My riding is mellow and on hard, rocky ground, and grass fields. I almost never see mud or snow. I’m looking for SOFT riding tires (for my old back), but all the reviews I see talk about mud and snow. Does anyone have a suggestion for soft riding tires that are not going to chew up the ground (I want to ride across my grassland without ripping it up). Thanks for your suggestions.
