For those of you that have not ridden a mower that has bar/lug tires. It can be a very bumpy ride. I had a set of them on the front of my first Toro 117 Groundsmaster. The ride was very bumpy on hard surfaces and less so on a lawn depending on how wet the ground was. If I still had those tires I would consider shaving down the foreward part of the lugs so the ride was better. It would be great if one of those tire companies ran a continious rib down the center of the tire to soften the ride.
