Cooper Discoverer Stronghold AT LT245/75R16 120/116S MPN 170277048

Is the Cooper Discoverer Stronghold AT LT245/75R16 120/116S MPN 170277048 the wheel & tire clearance pick here, or just one of three?

Cooper Discoverer Stronghold AT LT245/75R16 120/116S MPN 170277048 is recorded as an exact MPN row, so shoppers can compare one tire size instead of a broad family label.

Put it next to the Continental TerrainContact A/T 245/65R17 107T MPN 15506800000 and the Falken Rubitrek A/T 265/70R16 112T MPN 28074121 and the Cooper Discoverer Stronghold AT LT245/75R16 120/116S MPN 170277048 leads for one kind of buyer while giving ground elsewhere. None of the three is the automatic answer, so read the package, fitment, and install rows before you read the price.

Workshop & DIY Guidelines

Cooper Discoverer Stronghold AT LT245/75R16 120/116S MPN 170277048 Installation & Fitment Protocol

Wheel fitment is governed by three interrelated geometric factors: bolt circle diameter, wheel offset (ET in millimeters), and backspacing (inches from the back lip to the mounting surface). Lower or negative offset wheels push the tire outward for an aggressive stance, which increases the scrub radius and swings the outer shoulder into bumper valances and cab mounts during steering.

Install Difficulty

Shop & Bench Specs

Difficulty: Beginner (1/5)

Estimated Install Time: 1.0 – 1.5 hours (Wheel Mounting & TPMS Pairing)

Required Tools

Installation Equipment

  • Floor jack & jack stands
  • 1/2" Drive calibrated torque wrench
  • Thin-wall protective lug nut socket set (prevent wheel finish damage)
  • Tire pressure gauge
Post-Install Safety

Post-Install Protocol

  • Torque lug nuts in a criss-cross star pattern to manufacturer spec in two stages (first 50%, then 100%).
  • Perform mandatory re-torque check after 50 to 100 driving miles.
  • Verify full steering lock-to-lock clearance at ride height and during full suspension compression.

Wear Triggers & Maintenance Checks

  • Wheel bearing stress and premature hub assembly wear when running extreme negative offset (-12mm to -44mm).
  • Cupping or feathering wear on oversized tires when run at incorrect cold inflation pressures.
  • Caliper bracket scoring if wheel inner barrel clearance is under 3mm.

Chassis Fitment Context

Tacoma IFS uses an approximate 1:2.0 motion ratio. A 1.0-inch physical top strut spacer provides 2.0 inches of net lift at the hub. Wheel fitment is sensitive to center bore (106.1mm) and backspacing (4.5" to 4.75" is the sweet spot for 285/70R17 tires to clear upper control arms while minimizing cab mount rub).

The 3rd Gen (2016-2023, N300) utilized the 3.5L Atkinson V6 and rear leaf springs. In 2024, the 4th Gen debuted on the TNGA-F boxed platform with the i-FORCE 2.4L Turbo / i-FORCE MAX Hybrid, multi-link rear coil suspension on most trims, disc brakes on all four corners, and modernized electrical architecture.

Pre-Installation Unboxing Verification Checklist

Step 01: Confirm Physical SKU & Labeling

Inspect outer box label against your order invoice and the manufacturer part number shown here before opening hardware bags.

Step 02: Dry-Fit & Hardware Inventory

Unpack fasteners, brackets, and instructions. Perform a preliminary dry-fit check against the vehicle before removing factory components.

Step 03: Review Torque & Thread Requirements

Identify critical torque values and whether thread locker (Blue Loctite) or anti-seize compound is required by the manufacturer.

Step 04: Plan Post-Install Calibration

For suspension, steering, or lighting parts, schedule a professional alignment and verify forward-facing ADAS sensor calibration.
