FIRST: SimpleTire's service is phenomenal! I made a small purchase for 2 of these tires for my ZTR and they treat me like I ordered Michelin's for a fleet of trucks. THE REVIEW: These Carlisle knobby tires are amazing!! My Cub Cadet RZTL is now able to do so much more. It mows without slipping at all now. It actually doesn't tear my lawn up like my original tires did (even though those tires were very smooth, 'lawn-safe' tires. It's also able to easily push large logs out of the way now without me having to dismount the mower.
