The 2017 GMC Trucks Acadia Limited sits at an interesting point in GMC history, carrying forward the larger first-generation Acadia format even as the broader crossover market moved toward more space-efficient designs. For owners, that means balancing family-vehicle practicality with the need to keep ride height, stance, and road manners in line with the original setup. This Acadia Limited uses a 255/55R20 radial tire on a 20-inch rim, so the fitment question is straightforward. The real choice centers on selecting the right tire within that size and confirming compatibility if the vehicle has seen wheel or suspension changes. That approach helps preserve both appearance and everyday drivability.
Which Tire Size Is Right for The 2017 GMC Trucks Acadia Limited
The 2017 GMC Trucks Acadia Limited uses one primary tire size: 255/55R20 radial on a 20-inch rim. Fitment is consistent across the covered Base sub-model, so the main decision is not between multiple sizes, but between tire choices within 255/55R20 and making sure the current wheel and vehicle setup still match that specification.
A 255/55R20 size uses a 255-millimeter nominal section width, a 55-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2017 GMC Trucks Acadia Limited, this modern metric radial format reflects a contemporary crossover fitment rather than a vintage bias-ply sizing system. Because the vehicle uses a single primary size, selection usually comes down to choosing a tire that matches the intended road use, ride character, and overall setup. It is still worth confirming the actual wheel diameter and checking clearance if the Acadia Limited has aftermarket wheels, suspension changes, or previous size substitutions.
Sub-model fitment for the 2017 GMC Trucks Acadia Limited is straightforward. The covered Base model uses the same primary tire size, so the focus stays on selecting the right 255/55R20 tire and verifying that the vehicle still carries its correct 20-inch wheel setup.

2017 GMC Trucks Acadia Limited Base
The 2017 GMC Trucks Acadia Limited Base uses the 255/55R20 radial tire size. That makes tire selection relatively simple, with the main checks being wheel condition, current wheel diameter, and whether any previous modifications could affect clearance or overall fitment.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
Owners of a 2017 GMC Trucks Acadia Limited usually need quick answers on the 255/55R20 size, 20-inch rim fitment, tire selection, and what to inspect before regular road use or after any wheel and suspension changes.
Tire Size & Fitment
What tire size fits a 2017 GMC Trucks Acadia Limited?
The 2017 GMC Trucks Acadia Limited uses a 255/55R20 radial tire. That is the primary fitment for this vehicle and it is built for a 20-inch rim, giving the Acadia Limited a straightforward modern metric tire setup rather than multiple factory-era sizing conventions.
The practical next step is confirming that the vehicle still has the correct 20-inch wheels in place. If a previous owner changed the wheels, altered the suspension, or substituted another size, those changes should be checked before choosing a replacement tire in 255/55R20.
What size rim does a 2017 GMC Trucks Acadia Limited use?
The 2017 GMC Trucks Acadia Limited uses a 20-inch rim with its 255/55R20 tire size. In the size code, the final number, 20, identifies the wheel diameter the tire is designed to mount on.
Wheel diameter is the first fitment detail to confirm before replacing tires, especially on a used vehicle. A tire marked 255/55R20 is only intended for a 20-inch wheel, so checking the actual wheel size prevents ordering the right section width and profile for the wrong rim diameter.
Does the 2017 GMC Trucks Acadia Limited Base use the same tire size?
Yes. The 2017 GMC Trucks Acadia Limited Base uses the same 255/55R20 radial tire size. That keeps fitment simple at the sub-model level, since there is not a separate primary size to sort out for the covered Base configuration.
Even with shared sub-model fitment, it still helps to verify what is actually on the vehicle today. Replacement decisions should account for the current wheel diameter, any non-stock wheel package, and any suspension changes that could alter clearance or affect how a new 255/55R20 tire sits on the vehicle.
Choosing the Right Tire
What should I consider when choosing a 255/55R20 tire for a 2017 GMC Trucks Acadia Limited?
Start with the correct primary size, which is 255/55R20 radial on a 20-inch rim. From there, the main considerations are whether the tire suits the Acadia Limited's intended use, how closely it matches the existing wheel setup, and whether the vehicle remains in stock ride-height and wheel configuration.
Selection becomes easier once the basics are confirmed on the vehicle itself. Check wheel condition, verify that all four wheels are the same diameter, and compare the replacement tire to any current fitment issues such as rubbing, uneven wear, or steering clearance concerns.
How do I choose between available 255/55R20 tires for a 2017 GMC Trucks Acadia Limited?
The best way to compare 255/55R20 options for a 2017 GMC Trucks Acadia Limited is to begin with fitment, then narrow the choice by intended use and vehicle condition. A daily-driven crossover, a lower-mileage family vehicle, and a vehicle with prior modifications may not call for the same priorities.
Look closely at how the Acadia Limited is actually used before making the final decision. A tire that matches the existing wheel setup, clears properly at full steering lock, and supports stable road behavior on the vehicle's current suspension condition is the smarter choice than simply matching the size code alone.
Why does correct 255/55R20 fitment matter on a 2017 GMC Trucks Acadia Limited?
Correct 255/55R20 fitment matters because the 2017 GMC Trucks Acadia Limited was set up around that tire size and a 20-inch rim. Changing size without careful checking can affect wheel compatibility, clearance, stance, and the way the vehicle feels in normal road use.
Even when a substituted tire seems close on paper, small differences can create problems around struts, fenders, or steering travel. Staying with the proper primary size is the simplest path unless there is a clear reason to change, and any departure should be checked carefully against the actual wheel and vehicle setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 GMC Trucks Acadia Limited?
Yes. Wheel changes, suspension alterations, lowering, leveling, or previous tire substitutions can all affect tire fitment on a 2017 GMC Trucks Acadia Limited. Even though the primary size is 255/55R20, modifications can change how much room the tire has at the fender, suspension, and steering points.
A modified vehicle should be checked with the wheels turned lock to lock and with the suspension carrying normal weight. That helps reveal rubbing, close clearance, or uneven positioning before a new set of tires goes into service on a wheel and chassis setup that may no longer be standard.
What should I inspect before driving a 2017 GMC Trucks Acadia Limited on new tires?
Before road use, inspect the wheel condition, verify the 20-inch rim size, and make sure the new tires are all the correct 255/55R20 size. It also helps to check inflation, valve stems, lug torque, and whether any visible suspension or alignment issues were already affecting the previous tires.
A short initial drive can confirm that the tires track properly and clear at full steering input. Pay attention to vibration, pulling, unusual noise, or signs of contact inside the wheel opening, since those clues often point to wheel damage, alignment problems, or prior fitment changes that need attention.
How often should tires on a 2017 GMC Trucks Acadia Limited be inspected?
Tires on a 2017 GMC Trucks Acadia Limited should be inspected regularly, not just when tread looks worn. Frequent checks for pressure loss, uneven wear, cuts, bulges, and sidewall damage are especially important on a vehicle that sees mixed daily use, long highway trips, or extended periods of sitting.
Routine inspection helps catch fitment and maintenance issues before they become larger problems. Looking over the tires during washing, fueling, or service visits makes it easier to spot alignment changes, suspension wear, or slow air loss early, which protects both the tire investment and the vehicle's road manners.
