ask your tire professional about recommended load ratings, how much equipment or load do you plan to haul daily.
The "harder" the tire compound, the longer it lasts, but with less grip. - The "softer" the compound, the better grip & ride, but less longevity.
For my purposes, a 40,000 mile tire is about right. Too hard & the wet weather traction disappears, which is not fun in a truck full of tools.
