Impressive Tire

2023 Ford F-250 Super Duty XLT
By Chris
I have these tires on my 2023 super duty, with 1.5 inch leveling springs in the front. I am running between 60 and 65 psi and have around 10,000 miles on them. They are extremely smooth and quiet and have worn surprisingly well. I expect to get between 50 and 60,000 miles out of them. I shockingly saved over $1000 versus a set of Nitto Ridge Grapplers… I will look at Hercules for other vehicle needs too! Cars, trucks, SUVs, and ATVs.

2023 Ford F-250 Super Duty XLT
By Chris
Mounted on Ford stock wheels; tires sit even with the fenders. Perfect fitment with 2” level. Running 60 psi in the front and 55 psi in the rear. Very smooth and quiet. Track straight and true. Ample sidewall flexibility. Dual sidewall design and great tread pattern. Will buy them for other vehicles too, trucks, SUV’s. Impressive so far.
