Rugged Nitto Ridge Grappler tires in size LT275/65R20. The tires have a tread depth measuring approximately 08/32 to 11/32 of an inch as shown by the depth gauge. These come brand new 16/32 so about 50% life these tires were $425 each. The fronts have some outer ware due to a camber issue on my truck you can rotate that tire inward only asking $100 per tire since they are 4 years old and clearly not brand new.
