Cooper Discoverer S/T Maxx LT245/75R16 120/116Q MPN 170064004

Gladiator build that sees real dirt and rock?

The S/T Maxx is the hybrid, do-work tire here.

Cooper's Discoverer S/T Maxx in LT245/75R16 120/116Q is a rugged hybrid tire -- between all-terrain and mud-terrain -- on a tall, high-load LT-metric 16-inch fitment, checked against a Jeep Gladiator with a comfort-first Bridgestone Ascent and a Falken Rubitrek as peers. It is the most aggressive, highest-load option of the three. It leads when your Gladiator actually works off-road and you want LT toughness on smaller-diameter wheels.

Cooper Discoverer S/T Maxx LT245/75R16 120/116Q MPN 170064004 is an exact SimpleTire row promoted into the truck tire catalog for 2024 Jeep Gladiator Rubicon Crew Cab 4x4 planning with official tire-family docs and a current seller price snapshot.

Choose it if

  • Cooper Discoverer S/T Maxx LT245/75R16 120/116Q MPN 170064004 is tracked as an exact MPN row, so shoppers can compare one tire size instead of a broad family label.
  • The 2024 Jeep Gladiator Rubicon Crew Cab 4x4 route keeps offset, diameter, load, and rim-width checks visible before the offer is treated as a match.
  • Seller price, rating context, warranty resources, exact tire specs, and fitment checks are present, but final stock and shipping terms still belong in checkout.
  • Use these Gladiator tire rows when the exact tire diameter, load rating, rim width, service description, spare fit, and 5x127 wheel setup stay inside the checked Rubicon route limits.

Pass if

  • The Cooper Discoverer S/T Maxx LT245/75R16 120/116Q MPN 170064004 is not the right choice when your truck falls outside 2020-current Jeep Gladiator current midsize trucks, or its trim, engine, and package cannot be matched to the documented application.
  • Pass when this exclusion applies: Wrangler, Mojave, dealer-lift, non-Rubicon, or Ram crossover claims without exact route evidence
  • Choose another size or construction when load capacity, wheel width, offset, rubbing clearance, ride, or spare-tire needs point elsewhere.

Verify

  • Exact tire MPN, tire size, and four-tire price
  • Load range, service description, rim width, and tire diameter
  • Wheel offset, brake clearance, seller stock, shipping, returns, and installer requirements
  • The checked shelf is a 2024 Jeep Gladiator Rubicon Crew Cab 4x4 route; Mojave, Sport, Willys, dealer-lift, non-Rubicon axle, aggressive-offset, and aftermarket suspension setups need their own clearance and seller checks.
