Mastercraft Courser MXT 37/12.50R-20

Mastercraft Courser MXT is waiting to provide endless hours of extreme off-road, mud terrain performance. For light trucks and off-road adventurers, this tire bites into the ground with its wide, deep tread grooves and side biter design. The Courser MXT can handle off-road mud and snow. It was built to be driven hard and pushed to the limits of nature.

Features & Benefits

  • The Void to Rubber Ratio is optimized to give the maximum tire on the road surface, giving extreme terrain traction and a smooth driving feel.
  • Side Biter upper sidewall design helps increase off-road traction and make it harder for tires to wear along the sides.
  • Traction Edges and Large Shoulder Scallops offer a 'mud scoop' which increases traction - no more mud caked tires that slip and slide; the edges of the traction provide an additional grip for rough terrain.
  • Wide Shoulder Grooves placed between the outer tread blocks make it easy to clean your MXT tires.
  • Full-Depth and Variable Siping gives increased traction in wet conditions on the highway and enhance off-road driving.
  • Long-lasting tires can be half worn and 80% of the MXT sipes remain functional.
  • M+S Rated.

Ratings & Reviews

Mastercraft Courser MXT

Just had a set put on my H3 . Look Great! Heading out on a road trip on Wednesday, will see how they handle on wet roads. Love the " mean" look.
Chad Edwards
I have no complaints about these tires as of yet.
Cameron Sparks
I have around 6500 miles on the tires now, i have them on a chevy 1500 2wd. they work awesome! I dont do any extreme offroading, I will in some cases get in low to moderate mud and these tires seem like they say to me dude is that all you can get into. I mean i used to get stuck all the time in some All terrain tires, so i purchase the MT's and it like night and day. I actually try to get my truck stuck and it js aint happen in these tires on my 2wd. Road noise is low, all though i am starting to notice them more as the tread wear, but again the freak-in mud tires, what do you expect. I hit curves with these tires by accident, and the sidewall protection is pretty good to. So no complaints with this tire. if something crazy happens. then i will definitely write another review. As of now im running the tires again for sure once they wear out. Cheaper option compared to what EVERYBODY else is doing running TOYO tires. Mud: Excellent Wet road: Good, they will slip from time to time but they get traction REAL quick, plus i drive chevy with a rake on the back end. Snow: Not sure yet, i live in texas, lol so. Sand: Haven't tried yet Rock: Haven't tried, sorry. PS: I've had 3 random chicks say they like my truck, since I put the new tires on, lol js sayin.
