Review of the Toyo Open Country Mud Terrain Tire

Toyo recently introduced its newest tire, the Toyo Open Country Mud Terrain (M/T) radial.  While this tire isn't the traditional hardcore rockcrawling or extreme mud tire; it will survive the toughest backcountry challenges and perform well.  The targeted market for the Open Country is those who need a comfortable, quiet, well mannered daily driven Mud Terrain tire that works as a weekend warrior on moderate to tough terrain, tackling serious trails.  To accommodate a wide range of buyers, the Open Country M/T was packed with technology to make it capable of handling severe heat and frequently changing loads. It has an aggressive tread for traction and good looks, deep siping and an open-shoulder design for improved grip, and tread-block stabilizers. The tire uses a three-ply polyester casing, two wide steel belts, and two spiral-wound nylon cap plies, all of which make handling comfortable and predictable, on dirt or asphalt. In addition to its durable construction, the Open Country M/T uses an abrasion-resistant compound in the sidewall, shielding its most vulnerable area. This tire has an excellent load rating, possibly the highest available in a mud terrain: the 38x15.50x18LT tire has a 128 rating, meaning it can handle up to 3960 pounds per tire. It's also capable of a 99-mph top speed.

Mike -

"Jeep Wrangler Rubicon - 35 x 12.50 x17 - I had a set of the Goodyear Wrangler MTr's and they were good but VERY LOUD!!. I love my Toyo's. they are awesome on the road and are very quiet as well compared to the wranglers. they do have a slight slight hum to them but nothing like the nobbyness of the wranglers. I have seem them perform off road as well with a friends jeep and they are awesome there as well. I haven't seen them in wet weather yet but I live in florida so its just a matter of time. Overall this tire is the best that I have ever had on my jeep. AWESOME TIRE!!!"
