The 2018 GMC Vans Savana 3500 sits in the long-running tradition of full-size GM work vans built for hauling people, tools, cargo, and equipment with straightforward durability. For owners still using these vans as intended, tire choice is less about nostalgia and more about load support, road manners, and dependable fitment. This model uses a 245/75R16 radial tire on a 16-inch rim, and that consistency keeps the fitment decision simple across the covered Savana 3500 lineup. Available choices in this size focus on modern radial construction and truck-oriented design, including raised white letter styling. The main task is choosing a tire that matches the van's wheel setup, use, and load demands.
Which Tire Size Is Right for The 2018 GMC Vans Savana 3500
The 2018 GMC Vans Savana 3500 uses one primary tire size: 245/75R16, a radial fitment for a 16-inch rim. Base, LS, and LT models share that same size, so the decision is less about identifying different factory fitments and more about selecting the right tire within that size for load capacity, sidewall appearance, and the van's intended use.
A 245/75R16 tire uses a metric sizing format in which 245 is the nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 16 is the rim diameter in inches. On the 2018 GMC Vans Savana 3500, this is a modern radial fitment suited to the van's heavy-duty full-size role. Available choices in this size include BFGoodrich's All Terrain TA KO2 with raised white letter styling. It is the right size to evaluate when the goal is maintaining proper fitment while choosing a tread and sidewall presentation that matches how the van is used.
Tire fitment is straightforward across the covered 2018 GMC Vans Savana 3500 sub-models. Base, LS, and LT versions all share the same primary tire size, so checking the sub-model mostly helps confirm that the van has not been altered with a different wheel setup.

2018 GMC Vans Savana 3500 Base
The 2018 GMC Vans Savana 3500 Base uses the shared 245/75R16 radial fitment found across this covered lineup. Tire selection therefore centers on choosing the right product within that size and confirming wheel width, load needs, and overall condition before putting the van back into regular service.
The 2018 GMC Vans Savana 3500 LS uses the same 245/75R16 radial tire size as the other covered sub-models. That keeps sizing simple and shifts attention to practical details such as rim compatibility, tire construction, and whether the selected tire matches passenger, cargo, or mixed-use duty.
The 2018 GMC Vans Savana 3500 LT also uses the common 245/75R16 radial fitment. For this sub-model, the key step is selecting a tire in the correct size that aligns with the van's wheel specifications and the kind of road use, load carrying, or all-terrain service expected.
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.

Tire Size & Fitment
What tire size fits a 2018 GMC Vans Savana 3500?
The 2018 GMC Vans Savana 3500 uses a 245/75R16 radial tire. That primary fitment applies across the covered Base, LS, and LT sub-models, which keeps size selection much simpler than on vehicles that changed tire size by trim or package.
Choosing the correct size is only the first step. It still makes sense to confirm that the van is running the expected 16-inch wheels, especially if it has seen fleet service, wheel replacements, or commercial upfitting. Once size is confirmed, compare rim-width compatibility, load capacity, tread design, and intended use rather than looking for a different primary size.
What size rim does a 2018 GMC Vans Savana 3500 use?
The 2018 GMC Vans Savana 3500 uses a 16-inch rim with its 245/75R16 tire size. That rim diameter is part of the tire code itself, and it is the wheel diameter that must match before any tire in this size can be considered.
Rim diameter should not be confused with rim width. A tire may match the 16-inch diameter and still require a wheel width that falls within the tire's approved range. If the van has aftermarket wheels or a replacement wheel from another application, verify both diameter and width before mounting a new set.
Do all 2018 GMC Vans Savana 3500 sub-models use the same tire size?
Base, LS, and LT versions of the 2018 GMC Vans Savana 3500 all use the same 245/75R16 radial tire size. That shared fitment means the basic sizing question does not change across the covered sub-model range.
Even with one common size, the actual van should still be checked before replacement. Commercial vans are often modified with different wheels, suspension changes, or service-body equipment that can affect clearance and load demands. Shared factory sizing helps narrow the search, but the final choice should still match the van's present setup and work requirements.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 tire for a 2018 GMC Vans Savana 3500?
Start with the correct size, 245/75R16, and confirm that the tire is appropriate for a heavy-duty full-size van. Construction, load capacity, tread design, and wheel compatibility all matter more here than cosmetic differences alone, especially on a Savana 3500 that may carry passengers, cargo, or work equipment.
A useful comparison also includes the van's actual use. A highway-focused van may need a different tread character than one that sees gravel lots or mixed on-road and off-road conditions. Rim width should be checked carefully, and any tire choice should be evaluated against the van's usual load, service environment, and overall wheel condition.
What sidewall styles are available for 2018 GMC Vans Savana 3500 tires?
The available 245/75R16 product for the 2018 GMC Vans Savana 3500 uses RWL sidewalls, meaning raised white letters. That gives the tire a more aggressive light-truck appearance than a plain blackwall and may appeal to owners who want a more traditional all-terrain look.
Sidewall style is mostly an appearance decision, but it should come after confirming the correct size, construction, and wheel compatibility. On a work-oriented van like the Savana 3500, the more important questions are whether the tire meets the vehicle's load demands and whether its tread and casing match the van's day-to-day use.
What brands offer tires for the 2018 GMC Vans Savana 3500?
BFGoodrich is represented in the available 245/75R16 fitment for the 2018 GMC Vans Savana 3500. The current option is part of the All Terrain TA KO2 line, which places the focus on a truck-oriented radial tire rather than a broad spread of passenger-style choices.
Brand alone should not decide the purchase. A Savana 3500 owner should compare the tire's load rating, rim-width compatibility, sidewall style, and tread character against the van's actual use. For a vehicle that may spend long hours loaded or on varied surfaces, those details usually matter more than simply choosing by brand name.
Restoration & Appearance
Which tire should I choose for a period-style 2018 GMC Vans Savana 3500?
A period-style approach on a 2018 GMC Vans Savana 3500 still begins with the correct 245/75R16 radial size. Because this is a modern full-size van rather than an earlier collector-era application, the emphasis is less on vintage construction and more on keeping the overall look and stance consistent with the van's original-era roadgoing character.
Appearance choices should stay secondary to fitment and load requirements. A raised white letter sidewall can give the van a more traditional truck look, while the correct overall size helps preserve the visual balance of the wheel opening. Any owner pursuing a highly exact presentation should also compare against vehicle-specific photos or build documentation.
Does correct tire fitment matter for a 2018 GMC Vans Savana 3500 restoration?
Correct tire fitment matters because tire size shapes both the van's appearance and its real-world usability. On a 2018 GMC Vans Savana 3500, staying with the proper 245/75R16 size helps maintain the intended relationship between the wheel, body opening, and ride height.
Restoration-minded owners should also think beyond appearance. A full-size van places meaningful demands on its tires, so wheel diameter, wheel width, and load capacity deserve just as much attention as sidewall presentation. Even on a visually focused project, the tire should still suit the van's expected service rather than simply match a look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 GMC Vans Savana 3500?
Yes, modifications can affect tire fitment on a 2018 GMC Vans Savana 3500 even when the original size is 245/75R16. Aftermarket wheels, suspension changes, ride-height alterations, brake conversions, or commercial upfit equipment can all change the space available around the tire and wheel.
A van that still uses a 16-inch wheel may not automatically accept every tire in that size if wheel width or offset has changed. Clearance at the fender, steering components, and suspension should be checked carefully. Any modified Savana 3500 should be evaluated as it sits now, not only by its original factory sizing.
What should I inspect before driving a 2018 GMC Vans Savana 3500 on new tires?
Before road use, inspect wheel condition, lug hardware, valve stems, and tire pressure, then look over the suspension and steering for obvious wear. On a heavy-duty van like the 2018 GMC Vans Savana 3500, uneven wear or loose front-end parts can quickly affect how a new tire performs.
It also helps to confirm that the tires clear properly at full steering lock and under normal load. After the first miles, recheck inflation and look for any signs of rubbing or unusual wear. A short inspection routine is especially worthwhile on vans that have been parked for long periods or recently returned to service.
How should 245/75R16 tires on a collector or low-use 2018 GMC Vans Savana 3500 be maintained?
Low-use 245/75R16 tires on a 2018 GMC Vans Savana 3500 should be kept at proper pressure and inspected regularly for cracking, bulges, cuts, uneven wear, and signs of air loss. Even when tread looks good, a van that sits for long stretches can develop age-related tire issues that are easy to miss.
Storage conditions matter as much as mileage. Try to keep the van away from prolonged sunlight, excess heat, moisture, and ozone sources, and move it occasionally to avoid long-term flat spotting. Before any longer drive, check pressure again and give each tire a close visual inspection, especially on a vehicle used only seasonally.
