We tow our 2021 Montana 3121RL rig with a 2021 GMC Sierra 2500 Diesel 4WD truck. This is the first time we’ve owned a truck and want to keep it properly serviced. The truck is 3 years old with almost 30,000 miles of which 13,000 are towing miles. What is the minimum tire tread depth you would not allow your tires to go below to ensure safe towing with the truck. Tires are now at 4/32 front and 5/32 rear.

Thoughts and recommendations?? TIA!
