My old 2380 had turf tires as I thought would be better for my lawn mowing needs. We have mainly sandy soil so the turf is more on the loose side and at times when making turns the turf tires kind of tore up the grass. Yesterday was the first mow with my new 2380 that has R4 tires, and I was pleasantly surprised to see they didn't tear things up. I was afraid that the more aggressive tread would do damage. I'm a believer now.
