2018 GMC Vans Tire Fitment Guide

The 2018 GMC Vans lineup carried forward one of the last true full-size American work van formulas, with the Savana continuing as a familiar choice for commercial fleets, passenger hauling, and utility conversions. In this model year, GMC kept the range straightforward, focusing more on payload and chassis capability than styling changes. For 2018 GMC Vans, both covered models share the same 245/75R16 tire size, so the main decision is less about model-to-model fitment and more about choosing the right tire type and sidewall character for how the van is actually used. Confirm whether you have a Savana 2500 or 3500 first, then verify the tire size and wheel specifications before choosing a replacement.

Which Tire Size Is Right for Your 2018 GMC Vans

One tire size covers the 2018 GMC Vans models here, and both the Savana 2500 and Savana 3500 use the same 245/75R16 size. That simplifies fitment, but it still helps to understand the size code, radial construction, and wheel requirements before choosing a tire. Getting that distinction clear up front saves time and helps match the tire to the van's intended use.

Year(s): 2018Fit(s): Savana 2500, Savana 3500Construction: RadialRim: 16 in

245/75R16 is a metric radial size with a 245-millimeter section width, a stated 75-series aspect ratio, radial construction, and a 16-inch rim diameter. In this size, BFGoodrich is available with an RWL sidewall, and the tire carries an S speed rating with a 112 mph ceiling. This size fits both covered 2018 GMC Vans models rather than a single trim or body style. It suits owners who want a modern radial tire for regular road use, utility duty, or a more truck-oriented appearance.

2018 GMC Vans Models

Two 2018 GMC Vans models are covered here. Both use the same tire size, so fitment does not change from one model to the other at the size level; the real difference is how each van is equipped and used, whether for heavier commercial work, passenger service, or general utility. Select a model below for model-specific fitment history and products.

2018 GMC Vans Savana 2500

The 2018 GMC Vans Savana 2500 sits in the middle of the Savana range, balancing full-size van space with substantial carrying capability for work or passenger use. Its 245/75R16 tires mount on 16-inch wheels, keeping it in the heavy-duty light-truck tire category rather than a passenger-car fitment.

Frequently Asked Questions

These answers focus on the shared 245/75R16 fitment used across 2018 GMC Vans models, along with wheel requirements, sidewall style, highway use, and the tire care points that matter on full-size vans that may spend long periods parked between heavier-duty trips.

Size Basics & Fitment

What tire sizes fit 2018 GMC Vans vehicles?

2018 GMC Vans vehicles covered here use one tire size: 245/75R16. That same size fits both the 2018 GMC Vans Savana 2500 and the 2018 GMC Vans Savana 3500. The tire mounts on a 16-inch rim, and the available product in this size fits rim widths from 6.5 to 8.0 inches.

That shared fitment makes the year-and-make question simple, but it does not eliminate the need to confirm the actual wheel before replacing tires. A Savana that has been used in commercial service may have had wheels changed over time, so checking the sidewall on the current tire and measuring or verifying the wheel width is still the right first step.

What does 245/75R16 mean on a 2018 GMC Vans tire?

On a 2018 GMC Vans tire, 245/75R16 means the tire is 245 millimeters wide, has a 75-series aspect ratio, uses radial construction, and fits a 16-inch wheel. The available example also carries a 120S service description in the size marking, with S indicating a 112 mph speed rating ceiling.

That decoding matters because every part of the code affects compatibility. Width and aspect ratio shape the overall profile, the R confirms radial construction, and the 16 ties the tire to the wheel diameter. When replacing tires on a Savana 2500 or 3500, matching the complete size marking is more useful than matching only the wheel diameter.

Do all 2018 GMC Vans models use the same tire size?

Yes. The 2018 GMC Vans Savana 2500 and 2018 GMC Vans Savana 3500 both use 245/75R16 tires in the coverage here. There is no split between the two models at the basic size level, so year and make alone get you close to the correct fitment.

Even with that shared size, owners should still verify the van's actual configuration before replacing tires. Full-size vans often see fleet use, wheel swaps, or load-specific tire changes, and those practical changes matter more than the model badge alone. Confirm the sidewall marking already on the van and compare it to the wheel dimensions before moving ahead.

Buying the Right Tire

What sidewall styles are available for 2018 GMC Vans tires?

The 245/75R16 tire available for 2018 GMC Vans here uses an RWL sidewall, meaning raised white letters. That sidewall treatment gives the tire a more aggressive light-truck look than a plain blackwall, which fits well with utility vans, camper conversions, and owners who prefer a more rugged appearance.

Sidewall style is partly cosmetic, but it can change the overall look of a Savana more than many buyers expect. A work-focused cargo van may lean toward a subdued appearance, while a recreational or off-pavement-oriented build may suit raised white letters better. Decide how original, commercial, or truck-like you want the van to look before choosing among products in the correct size.

What brands make tires for 2018 GMC Vans vehicles?

BFGoodrich offers a tire for 2018 GMC Vans in the 245/75R16 size. The available example is part of the All-Terrain T/A KO2 line, a well-known light-truck radial with a strong visual presence and a utility-minded character that fits the full-size van market well.

Brand choice matters because it often signals the tire's intended personality as much as its dimensions. On a Savana 2500 or 3500, a truck-oriented brand and series can make sense for owners who use the van for mixed pavement, work, or adventure-oriented duty. The best approach is to match the tire's character to how the van is really driven, not just to the size alone.

What is the difference between the BFGoodrich All-Terrain T/A KO2 and a typical highway-style tire for the 2018 GMC Vans?

For 2018 GMC Vans, the BFGoodrich All-Terrain T/A KO2 in LT245/75R16/E is a radial light-truck tire with an RWL sidewall, a 120S service description, a 3,042-pound maximum load at 80 psi, a 16-inch rim diameter, and a 6.5- to 8.0-inch rim width range. Those details place it firmly in the heavy-duty light-truck category rather than a softer passenger-oriented pattern.

That matters most for owners deciding how their Savana is used day to day. A tire with light-truck construction and all-terrain character can make sense on vans that carry gear, tow, or see rougher surfaces. If the van is mainly a road-going passenger or service vehicle, the right choice still starts with correct size, load range, and wheel fit rather than appearance alone.

Fitting & Setup

What rim width do 2018 GMC Vans tires require?

The 245/75R16 tire used on 2018 GMC Vans fits a 16-inch rim and works with rim widths from 6.5 to 8.0 inches in the available product. That gives the Savana platform a useful range, but the wheel still needs to be checked as an actual component rather than assumed from the model name alone.

Rim width affects how the tire sits, how the sidewall stands, and whether the tire is operating within its intended profile. Before replacing tires on a Savana 2500 or 3500, verify the wheel diameter and width on the van itself. That is especially important on commercial vans, which may have had replacement wheels installed during their service life.

Do 2018 GMC Vans tires require inner tubes?

The available 245/75R16 tire for 2018 GMC Vans is a modern radial truck tire, and nothing in the size marking points to a tube-type fitment. That places it in the tubeless light-truck category commonly used on modern full-size van wheels, unlike earlier collector-vehicle sizes that may require separate tubes.

Even so, tube use is never something to assume from age or appearance alone. The wheel itself must be suitable for tubeless service, and the valve stem condition matters just as much as the tire. If a Savana has seen fleet maintenance, camper conversion work, or wheel replacement, inspect the wheel and stem carefully before mounting new tires.

Maintenance, Storage & Longevity

How should I store a 2018 GMC Vans when the tires are fitted?

A 2018 GMC Vans should be stored on clean, properly inflated tires, away from direct sunlight, standing moisture, and ozone sources such as electric motors, battery chargers, and welders. Long periods of static storage can age the rubber even when tread wear is minimal, especially on vans that sit loaded or parked in one position for months at a time.

Moving the van periodically helps prevent flat-spotting and uneven stress on the carcass. If the Savana will be parked for an extended season, keep weight off one contact patch when possible, maintain inflation, and avoid storing it on contaminated concrete or dirt. Simple storage discipline often does more for tire life than low annual mileage.

How long do tires on a 2018 GMC Vans typically last?

Tires on a 2018 GMC Vans should be judged by age as much as by tread depth. A good rule is to begin evaluating them closely once they reach the five- to seven-year range and to consider replacement as they approach about ten years, even if they still look usable. The DOT date code on the sidewall is the starting point for that decision.

That guideline is especially important for full-size vans that are driven infrequently or only seasonally. Low mileage can make a tire seem healthy when the real concern is age hardening, internal degradation, or sidewall cracking. If a Savana carries passengers, cargo, or towing loads, conservative age-based replacement is a smarter approach than waiting for the tread to wear out.

How often should tires on a 2018 GMC Vans be inspected?

Tires on a 2018 GMC Vans should be inspected before every drive and again before any longer highway trip. Look for sidewall cracking, cuts, punctures, bulges, irregular wear, and pressure loss, and make sure the valve stems are in good condition. A full-size van can hide tire problems because load and body height sometimes mask early warning signs.

That quick inspection routine becomes even more important on vehicles used for work or carrying people. Check the inner sidewalls as well as the outer faces, since curb contact and underinflation damage are not always visible at a glance. Catching a problem in the driveway is far easier than discovering it after the van is fully loaded and already on the road.

Safety & Road Use

Are 2018 GMC Vans tires safe for highway driving?

Yes, the available 245/75R16 tire for 2018 GMC Vans is suitable for highway use when it is correctly matched, properly inflated, and in sound condition. The tire carries an S speed rating, which corresponds to a 112 mph ceiling. In normal real-world use, a Savana's condition, loading, alignment, braking system, and suspension health matter at least as much as the speed symbol on the sidewall.

Highway safety comes from the whole setup working together rather than from a size code alone. A full-size van places significant demands on its tires, especially when loaded, towing, or driven long distances in summer heat. Confirm the load capacity matches the vehicle's actual use, inspect the tires before travel, and avoid assuming that acceptable tread depth automatically means the tire is road-ready.

What inflation pressure should I use for 2018 GMC Vans tires?

For 2018 GMC Vans, the available 245/75R16 tire carries a maximum load rating of 3,042 pounds at 80 psi. That figure is the tire's maximum rated pressure and load point, not a universal instruction to run every van at 80 psi in normal use. Factory pressure recommendations belong to the van's placard or owner's manual and should be followed first.

Pressure should be matched to the exact tire, wheel, and service conditions rather than copied from another size or another vehicle. A lightly used passenger van and a heavily equipped work van may both wear the same tire size but need different real-world attention to inflation. Check pressures cold, use an accurate gauge, and revisit them any time load or seasonal temperatures change.

What should I check before taking a 2018 GMC Vans on a longer drive?

Before a longer trip in a 2018 GMC Vans, inspect each tire for cracking, embedded debris, cuts, bulges, uneven wear, and proper cold inflation. Check the valve stems, verify the spare is serviceable, and make sure the tread is wearing evenly across the axle. On a full-size van, tire condition should be part of a broader pre-drive check that includes brakes, steering, fluids, and lights.

That routine matters because vans are often asked to carry more weight, more passengers, or more equipment than a typical passenger car. A tire that seems acceptable for short local use may become a weak point on a sustained highway run in heat or under load. Giving the van a deliberate inspection before departure is one of the simplest ways to reduce roadside trouble.
