I currently run Michelin XZE LRH on the steer axle, but just discovered that both Michelin and Bridgestone have a 305/75R24.5 LRJ. These tire will carry more weight and though listed as low profile there is only about 8 Revs per mile difference. Would like to hear from tech support and any owners that may be using this tire. BTW with full fuel my front axle exceeds 15,000 pounds.
