The Nitto Mud Grappler 395/65R20, the metric version of a 40x15.50R20, is a 40 inch extreme mud-terrain for the biggest truck builds. If your truck is built to go where the mud gets deep, this is the tire Nitto made for it.
The Mud Grappler is Nitto's most aggressive extreme mud-terrain. Massive tread blocks, wide voids and heavy sidewall lugs throw mud out of the tread and keep digging where other tires pack up and spin. It is louder on the highway than the Trail or Ridge Grappler, so it suits a dedicated off road rig or anyone who lives in deep mud.
In 395/65R20, this is a load range D light truck tire with a 130 load index, rated for 4,190 lb per tire, with a deep 21/32 inch tread. Expect to need a 6 inch or larger lift, trimming and re-gearing, plus a wide 20 x 11 to 20 x 13 inch wheel.
