## Description

OTR Lawn Trac 18/8.5-8

Review: Giant increase in traction and directional stability for zero turn mower - I live in an area of the midwest that features steep realtively small hills (at least by comparison to Smokies or Rockies). Nonetheless you that own a zero turn know they are not at their best on steep terrain. I bought these for my Ryobi electric single joystick zero turn mower. I received abnormal amounts of rain in rapid succession this season and my lawn got way ahead of me ie it grew too long. Hills plus moist yard equal spirited mowing experiences. Not good. I finally investigated my choices and there is only one tire with an aggressive tread like this in the proper size for my mower. You are looking at it. The title of my review says it all. Noticeably better traction and stability while mowing. Way better than the OEM tires. No more gritting of the teeth when I first start my mow. If you own true turf, fancy pampered grass, this is not for you. If you turn too quickly you can mark your yard. Your ride will probably be bumpier like never before. That being said, if your like me, you live where its steep, you have a lawn of luxuriant weeds, grass, lots of clover, mole tunnels etc and you mow on a lower speed, there is only a barely perceptible loss of the evenness of your cut. But I now mow with way more confidence that I won't wind up at the bottom of my yard up to my axles in mud. I've received unsolicited compliments on how nice the yard looks. Works for me. I had my tires installed at a tire shop. I've seen other unverified reviews elsewhere from owners saying they were a tough self install. My shop had no problems. These are not a great value. They are expensive. They are the only game in my town. But I do consider them to be the realistic effective solution I needed. ZT owners with hills.....you know who you are.
Review: These tires are amazing - These tires are amazing. This is my second set of these. I put them on all my golf carts. A little bit of vibration at low speed but these tires will take you anywhere if you are doing any off-roading at all with your golf cart. These are the tires you need

### ⭐⭐⭐⭐⭐ Amazing Traction
*by F***S on March 10, 2021*

I purchased these tires for the rear of a club car golf cart. We use this card for backwoods working and around the ranch. Not wanting to do a lift kit but needed a more aggressive tire for snow mud and dirt. These tires will dig until they find something solid to move whatever you have them on. Even in 7 inch deep snow these tires allow our golf cart to travel uphill. I cannot recommend these tires enough. They are a bit more pricey than some other tires but I have not seen anywhere on these tires yet and I give them a good workout every day. They are a bit noisy on asphalt but that is to be expected as they are meant for off-road. That being said I do travel about 6 miles on asphalt every other day to visit the neighbor. Still no sign of deterioration on the tire. I did use a different tire for the front steering but I wanted something as aggressive as I could on the back. I could not find any reviews about putting them on golf carts so it was a risk that we were willing to take and we are glad we did it. They mounted up to the standard golf cart rim with no problem using a harbor freight tire changer for small tires. If you look at the photos you can see the back hills woods we take this cart into. These tires allow us to go places the 4x4 quads go With no trouble
