Looking for advice from those that mow hillsides. I need to replace the tires on my DDS52 and Hydrowalk36. Both had different tires, the Hydrowalk had Titan TurfSavers good for hills. The DDS52 had Carlisle TurfTrac R/S, horrible on hills. What tires have worked for you guys and what haven't? I kind of like the looks of the Carlisle Turf-Master or Multi-Trac but know nothing of them. Any help would greatly be appreciated, thank you.
