Lifted Grenadier: Tire Fitment, Driveline Risk & Height Math

Treat lift, tire, roof hardware, and garage clearance as one measured system. Published kit fitment does not prove tire clearance or driveline durability on every build.

Quick answer: Do not add catalog lift height, nominal tire diameter, and rack height to a brochure number and call the result guaranteed. Measure the exact vehicle before and after installation, at the roof's highest point, with operating pressures and the normal load.

Separate Four Different Questions

  • Suspension fitment: Does the kit maker list the exact Grenadier variant?
  • Tire clearance: Does the exact wheel offset, tire model, pressure, steering angle, and suspension travel clear?
  • Driveline geometry: Has the installer checked shafts, joints, hoses, wiring, and alignment through travel?
  • Overall height: What is the measured highest point after the roof system and cargo are installed?

Use Manufacturer Fitment as the Starting Point

Eibach publishes a Grenadier Pro-Lift product release for the application. That confirms the listed suspension product's intended vehicle fitment; it does not certify every wheel, tire, roof system, garage, alignment setting, or driveline combination. Use the current kit instructions and a qualified alignment/inspection process.

Tire Size Is Not a Clearance Guarantee

Nominal size does not capture measured tire diameter, section width, wheel offset, production tolerance, pressure, load, steering sweep, or articulation. Verify static clearance, full steering lock, compression and droop, brake-hose and wiring clearance, and contact marks on the exact vehicle.

Measure Garage Clearance

Measure floor-to-highest-point height after the build, on level ground, with the tires at operating pressure and the vehicle loaded as it normally enters the garage. Then measure the lowest part of the opening and any door, track, seal, sprinkler, or slope transition. Maintain a deliberate margin for load, pressure, snow, and floor variation.

Owner Reality Check

My Grenadier lifted on Eibach springs, factory wheels on BFG KO2 295 70 18’s.

Read the cited owner discussion. Owner reports identify practical questions; the OEM or product documentation establishes specifications and procedures.

Pre- and Post-Install Measurement Sheet

Record before Repeat after
Hub-to-fender height at all four corners Same surface, load, and tire pressure
Floor-to-highest-roof point Add each permanent roof component
Clearance at full steering lock Repeat through practical compression and droop
Driveline boots, joints, hoses, and wiring condition Inspect for fresh contact, heat, leakage, or movement

Stop-and-Inspect Symptoms

After a geometry change, new vibration, clunking, boot distortion, grease leakage, polished contact marks, tire rub, steering interference, or a changed alignment reading warrants inspection before more highway or trail use. These symptoms do not diagnose a component by themselves; they identify a condition that needs measurement.

I can confirm that the Mickey Thompson 255/85r17 fits without rubbing on factory wheels and factory suspension even under full articulation and at full steering lock.

This is a useful owner report for that exact tire, wheel, and stock-suspension combination—not a universal fitment specification. Read the thread.

My front driveshaft is toast, the joint at the diff is what failed. Setup: +30mm Eibach lift, OME shocks.

The same discussion later notes similar retention failures on stock vehicles, so it cannot prove that lift alone caused the failure. It does show why post-install driveline inspection matters. Read the full report.

DVA Roof Hardware in the Height Stack

The current DualTrack-T MAX Gen 2 page is the source for rail configuration and fitment. Add the actual rail, bracket, accessory, and cargo height to the measurement—not an old article price or retired product identity. Use the L-Track collection and Grenadier collection for current compatible hardware.
