My 2012 Ram 2500HD Cummins came with Michelin tires. Saved me an immediate expense to instal those same tires.

I upgraded the 2014 Classic to the same 16" Michelin LT225/75R16/E LTX M/S2 tires and SenDel T03-66655T wheels Airstream installed on the Eddie Bauer models and the 31' Classics starting in 2015 model year.

They offer them for sale as you walk into the Service Center at the factory. The load capacity per Michelin LT225/75R16/E LTX M/S2 tire of 2,680 pounds @ 80 psi is greater than the stock GYM ST225/75R15D tire rated 2,540 pounds @ 65 psi and is limited to 65 mph which is lower than the posted speed limits on most interstates.

I knew that using the same factory installed tires and wheels would protect the warranty and solve any other issues regarding the appropriate tire.

Upgrading both the 25FB and the 23D to the 15" Michelin LTX (P) 235/75R15 XL tires was farther out on the curve. But the derated capacity of 1,983 pounds at 41 psi exceeds the individual tire loads at all four locations with a significant higher safety margin the the 15" GYM tires provided on the Classic.
