The 2020 GMC Vans Savana 2500 remains one of the last traditional full-size vans built for real commercial duty, passenger hauling, and upfit work rather than crossover-style compromise. Its long-running body and proven chassis make it a practical choice for owners who value durability and straightforward serviceability. For this exact Savana 2500, the primary tire fitment is 245/75R16 radial on a 16-inch rim, and that simplicity keeps the decision focused on tire type rather than size confusion. Available choices in this fitment lean toward a rugged radial with raised white letter styling. The right selection should match how the van is actually used, while still confirming wheel width, load needs, and overall condition before road use.
Which Tire Size Is Right for The 2020 GMC Vans Savana 2500
The 2020 GMC Vans Savana 2500 uses one primary tire size: 245/75R16 radial on a 16-inch rim. That fitment is shared across the covered Base, LS, and LT sub-models, so the main decision is not which size fits, but which tire within that size best matches the van's load demands, road use, and preferred sidewall style.
A 245/75R16 size uses a 245-millimeter section width, a 75-series aspect ratio, radial construction, and a 16-inch rim diameter. On the 2020 GMC Vans Savana 2500, this is the core fitment and it suits the van's full-size working role with a modern radial layout. In this size, the available option is a BFGoodrich All Terrain TA KO2 with raised white letter styling, giving the tire a more assertive truck-style appearance than a plain black sidewall. Choosing within this size means checking wheel width, intended cargo or passenger use, and whether an all-terrain tread matches how the van is driven.
Tire fitment is straightforward across the covered 2020 GMC Vans Savana 2500 sub-models because each one uses the same primary size and construction. Checking the exact sub-model still helps confirm that the van remains on its intended wheel setup and has not been altered for a different use case.

2020 GMC Vans Savana 2500 Base
The 2020 GMC Vans Savana 2500 Base uses the same 245/75R16 radial fitment as the other covered trims. That keeps tire selection focused on choosing the right tread style, sidewall presentation, and wheel-width compatibility rather than sorting through multiple factory sizes.
The 2020 GMC Vans Savana 2500 LS follows the same 245/75R16 radial tire setup used across this model range. For the buyer, that means the priority is comparing tire character and service demands, then confirming the van's wheels and overall setup still match the standard fitment.
The 2020 GMC Vans Savana 2500 LT also uses the shared 245/75R16 radial fitment on a 16-inch rim. Tire choice here comes down to how the van is used, whether the current wheels stay within the tire's approved width range, and whether the selected tread suits highway or mixed-use driving.
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 2020 GMC Vans Savana 2500?
The 2020 GMC Vans Savana 2500 uses 245/75R16 tires. This is a metric radial size built for a 16-inch wheel, and it is the primary fitment across the covered Savana 2500 range.
That makes the size question fairly simple, but the van should still be checked before replacement. Confirm that the current wheels are actually 16-inch rims, that the van has not been changed to an aftermarket wheel package, and that the tire selected matches the way the vehicle is used for cargo, passengers, or mixed-duty driving.
What size rim does a 2020 GMC Vans Savana 2500 use?
The primary tire fitment for the 2020 GMC Vans Savana 2500 uses a 16-inch rim diameter. With a 245/75R16 tire, the final number in the size confirms that the tire is made for a 16-inch wheel.
Rim diameter is only part of the fitment picture, so wheel width matters too. A 16-inch wheel that is outside the tire's approved width range can create problems with tire shape and service life, which is why wheel width should be confirmed before replacing worn tires or changing to a different tire design.
Do all 2020 GMC Vans Savana 2500 sub-models use the same tire size?
Yes. The covered 2020 GMC Vans Savana 2500 Base, LS, and LT sub-models all use the same 245/75R16 radial tire size. That shared fitment keeps tire selection more straightforward than on vehicles with trim-specific wheel packages.
Even with a common size across the range, it is still worth checking the van itself before ordering tires. Commercial vans are often repurposed, upfitted, or placed on replacement wheels during service life, so confirming the actual wheel diameter and width on the vehicle helps prevent ordering a tire that matches the model but not the current setup.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 tire for a 2020 GMC Vans Savana 2500?
Start with the correct 245/75R16 size, then look at construction, load specification, tread style, and wheel compatibility. For this Savana 2500, the available product is a radial all-terrain design, which gives the van a more truck-oriented character than a plain highway-style tire.
Selection should reflect how the van is actually used. A Savana that sees jobsite access, rough pavement, or mixed driving may suit an all-terrain tread, while a lightly used passenger or service van owner may be focused more on appearance, ride expectations, and keeping the tire within the proper rim-width range.
What sidewall styles are available for 2020 GMC Vans Savana 2500 tires?
The available 245/75R16 product for the 2020 GMC Vans Savana 2500 uses an RWL sidewall, meaning raised white letters. That gives the tire a more pronounced light-truck appearance than a plain blackwall presentation.
Sidewall style does not change the basic fitment size, but it does affect how the van looks once the tires are installed. Owners who want a more understated commercial appearance may pay close attention to sidewall treatment, while others may prefer the more aggressive visual character that raised white letters bring to a full-size van.
What brands offer tires for the 2020 GMC Vans Savana 2500?
BFGoodrich is available in the 245/75R16 fitment for the 2020 GMC Vans Savana 2500. The current product offering in this size is the All Terrain TA KO2, a radial tire with a light-truck-oriented design.
Brand is only one part of the choice, so it helps to compare the full tire package rather than the name alone. On a Savana 2500, wheel-width compatibility, load specification, tread character, and intended use all matter, especially if the van is expected to carry weight regularly or split time between pavement and rougher surfaces.
Restoration & Appearance
Which tire should I choose for a period-style 2020 GMC Vans Savana 2500?
A period-style approach on a 2020 GMC Vans Savana 2500 usually means staying with the original fitment size and avoiding visual changes that make the van look modified. In practical terms, that starts with a 245/75R16 radial on the correct 16-inch wheel.
Because this is a modern full-size van rather than a vintage restoration project, the visual goal is usually clean factory-inspired proportion rather than strict historical judging. The best approach is to keep the tire size consistent, confirm the wheel setup is still standard, and choose a tread and sidewall treatment that suit the van's intended character.
Does correct tire fitment matter for a 2020 GMC Vans Savana 2500 restoration or refresh?
Yes, correct tire fitment still matters on a 2020 GMC Vans Savana 2500, even if the goal is more of a clean refresh than a traditional restoration. The correct 245/75R16 size helps preserve the van's intended stance, wheel relationship, and overall visual balance.
Fitment also affects function, especially on a vehicle that may still see hauling or commercial use. A different size can change how the van looks in the wheel opening and may introduce clearance or wheel-compatibility issues, so matching the proper size and checking the current wheel package are worthwhile before replacing aging tires.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 GMC Vans Savana 2500?
Yes. Even though the primary fitment for a 2020 GMC Vans Savana 2500 is 245/75R16, modifications can change what works on the vehicle. Aftermarket wheels, suspension changes, lift or lowering work, and body alterations can all affect clearance and wheel compatibility.
A van that has spent time in commercial service may have been changed more than expected, so it is smart to inspect the actual setup before replacing tires. Check wheel diameter and width, look for rubbing marks near the wheel opening or suspension, and verify that the replacement tire still suits the van's working load and intended use.
What should I inspect before driving a 2020 GMC Vans Savana 2500 on new tires?
Before driving a 2020 GMC Vans Savana 2500 on new tires, inspect the wheels, valve stems, lug hardware, and basic suspension condition. Tire pressure should be set correctly, and the tires should be checked visually for proper seating and any signs of interference after installation.
A short initial road test is worthwhile on a full-size van, especially one used for hauling or fleet duty. Pay attention to vibration, pull, or rubbing during turns, then recheck inflation and look at the tread and sidewall after the first drive. That simple follow-up helps catch mounting or clearance issues before regular use.
How should 245/75R16 tires on a collector or low-use 2020 GMC Vans Savana 2500 be maintained?
245/75R16 tires on a low-use 2020 GMC Vans Savana 2500 should be inspected regularly for air loss, uneven wear, cuts, bulges, and sidewall cracking. Even when tread looks strong, a van that sits for long periods can develop age-related issues that are easy to miss.
Storage habits matter as much as mileage on infrequently used vehicles. Keep the van away from prolonged sunlight, excess moisture, and ozone sources when possible, maintain proper inflation, and check the tires before longer drives instead of assuming they are fine because the van has seen limited use since the last outing.
