The 2018 GMC Vans Savana 2500 is a full-size work van built for cargo duty, passenger hauling, and fleet use where durability matters more than trends. Its long-running platform has made it a familiar choice for owners who value straightforward utility and proven road manners. For this model, the primary tire fitment is 245/75R16 radial on a 16-inch rim, keeping the decision focused on choosing the right tire within that size rather than sorting through multiple factory sizes. Available options in this fitment lean toward truck-oriented radial construction, so the key is matching load capability, rim compatibility, and intended use before putting the van back into regular service.
Which Tire Size Is Right for The 2018 GMC Vans Savana 2500
The 2018 GMC Vans Savana 2500 uses one primary tire size: 245/75R16, and it is a radial fitment for a 16-inch wheel. That same size is shared across the covered Base, LS, and LT sub-models, so the main decision is not which size fits, but which tire in that size best matches the van's load demands, road use, and wheel specifications.
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 2018 GMC Vans Savana 2500, this is the standard fitment format, so the focus shifts from decoding size to choosing the right radial tire for the van's real workload. In this size, the available product uses a raised white letter sidewall and the BFGoodrich All Terrain TA KO2 series, giving the tire a more truck-oriented look and character. It is a practical size to evaluate by rim width, load capacity, and whether the van spends more time on pavement or mixed surfaces.
Tire fitment is straightforward across the covered 2018 GMC Vans Savana 2500 sub-models, with the same primary size used throughout. Checking the exact sub-model still helps confirm that the wheel and tire setup on the van has not been changed from its standard configuration.

2018 GMC Vans Savana 2500 Base
The 2018 GMC Vans Savana 2500 Base uses the same 245/75R16 radial tire size as the other covered trims. That keeps selection centered on the tire's load capacity, rim-width compatibility, and intended duty rather than on trim-specific size differences.
The 2018 GMC Vans Savana 2500 LS shares the 245/75R16 radial fitment used across this model range. Tire choice here comes down to selecting the right product in that size and confirming that the van still has the expected 16-inch wheel setup.
The 2018 GMC Vans Savana 2500 LT also uses 245/75R16 radial tires, so trim level does not introduce a separate primary size. That makes product comparison more important than size comparison, especially for owners balancing appearance, load demands, and regular road use.
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 2500?
The 2018 GMC Vans Savana 2500 uses a 245/75R16 radial tire size. That fitment applies across the covered Base, LS, and LT sub-models, so there is one primary size to focus on rather than separate trim-specific sizes.
A single-size fitment makes the choice more about selecting the right tire within 245/75R16 than about sorting through multiple factory options. It is still smart to confirm that the van still has 16-inch wheels and has not been changed with aftermarket wheels, suspension modifications, or a non-standard commercial setup.
What size rim does a 2018 GMC Vans Savana 2500 use?
The 2018 GMC Vans Savana 2500 uses a 16-inch rim with its 245/75R16 tire size. The available tire in this fitment is intended for a rim-width range of 6.5 to 8.0 inches, which gives a useful reference point when checking wheel compatibility.
Rim diameter and rim width both matter when replacing tires on a full-size van. A 16-inch diameter alone is not enough if the wheel width or wheel type has been changed, so checking the actual wheel before installation helps avoid clearance, wear, and handling issues.
Do all 2018 GMC Vans Savana 2500 sub-models use the same tire size?
Yes. The covered 2018 GMC Vans Savana 2500 Base, LS, and LT sub-models all use the same 245/75R16 radial tire size. That keeps fitment consistent across the main trim levels covered here.
Shared fitment simplifies tire shopping, but trim consistency does not override changes made over the life of the van. A work van may have replacement wheels, heavy-duty service modifications, or mixed tire history, so confirming the wheel size and current setup remains an important final check.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 tire for a 2018 GMC Vans Savana 2500?
Start with the correct 245/75R16 size, radial construction, and 16-inch wheel fitment. From there, compare practical details such as load capacity, rim-width compatibility, sidewall style, tire weight, and whether the van is used mainly for cargo duty, passenger service, or mixed on-road and light off-pavement use.
A full-size van places more importance on suitability than appearance alone. Matching the tire to how the Savana 2500 is actually used helps avoid compromises, especially if it carries tools, equipment, or regular payload. The wheel width and the van's current setup should be checked before settling on any one tire.
What sidewall styles are available for 2018 GMC Vans Savana 2500 tires?
The available 245/75R16 option for the 2018 GMC Vans Savana 2500 uses an RWL sidewall, meaning raised white letter styling. That gives the tire a more truck-oriented visual character than a plain blackwall sidewall.
Sidewall styling does not change the tire's basic size fitment, but it does affect how the van looks once installed. Some owners prefer a utility-focused appearance, while others want a more traditional white-letter presentation. The better choice depends on whether the Savana is used as a work van, personal hauler, or mixed-use vehicle.
What brands offer tires for the 2018 GMC Vans Savana 2500?
The available tire offering for the 2018 GMC Vans Savana 2500 in 245/75R16 comes from BFGoodrich. It is part of the All Terrain TA KO2 series and uses radial construction in a truck-duty format suited to the van's size class.
Brand is only one part of the decision. It still helps to compare the tire's sidewall style, rim-width specification, weight, and maximum load figure against how the van is used. A Savana 2500 that spends most of its time carrying cargo may call for different priorities than one used more lightly.
Restoration & Appearance
Does correct tire fitment matter for a 2018 GMC Vans Savana 2500 restoration?
Yes, correct tire fitment still matters on a 2018 GMC Vans Savana 2500, even though it is a modern full-size van rather than an older collector vehicle. Staying with the proper 245/75R16 size preserves the intended relationship between tire, wheel, and body proportions.
Appearance is only part of the picture on a vehicle like this. Correct size also supports proper clearance and keeps the van looking appropriate for its original design. If a restoration includes replacement wheels or trim changes, checking actual wheel dimensions helps keep the finished result visually balanced and mechanically sound.
Which sidewall style suits a period-style 2018 GMC Vans Savana 2500?
A raised white letter sidewall can suit a period-style 2018 GMC Vans Savana 2500 if the goal is a truck-oriented late-model appearance. In the current 245/75R16 offering, RWL is the available sidewall treatment, giving the tire a more assertive visual presence than a plain commercial-looking sidewall.
The right look depends on how the van is being presented. A cleaner, fleet-like build may call for a more subdued appearance, while a personal-use or recreation-focused Savana can wear raised white letters naturally. The main thing is to keep the correct size and wheel compatibility ahead of appearance preferences.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 GMC Vans Savana 2500?
Yes, modifications can affect tire fitment on a 2018 GMC Vans Savana 2500 even when the intended tire size remains 245/75R16. Aftermarket wheels, changes in wheel width, altered offset, suspension work, or body modifications can all change clearance and how the tire sits on the van.
A van used for work is especially likely to have seen changes over time, so it helps to inspect what is actually on the vehicle before replacing tires. Wheel diameter, wheel width, steering clearance, and fender clearance are worth confirming so the new tires match the van's real-world setup.
What should I inspect before driving a 2018 GMC Vans Savana 2500 on new tires?
Before driving on new tires, inspect the wheel condition, lug hardware, valve stems, and tire pressure, then make sure the tires clear the body and suspension through normal steering range. It also helps to confirm that all four tires match in size and general service type for predictable road behavior.
A Savana 2500 often sees heavier use than a passenger car, so a quick check of suspension wear, alignment condition, and brake condition is worthwhile as well. Early inspection after installation can catch rubbing, uneven wear, or inflation issues before they become larger problems in regular service.
How often should tires on a 2018 GMC Vans Savana 2500 be inspected?
Tires on a 2018 GMC Vans Savana 2500 should be inspected regularly, especially if the van carries cargo, sits for stretches between uses, or runs long service miles. Pressure, tread wear, cuts, punctures, bulges, and sidewall cracking are all worth checking as part of normal maintenance.
A full-size van can mask tire problems until they become more serious, particularly when it is loaded or used in commercial duty. Frequent visual checks and periodic hands-on inspection help catch uneven wear or air loss early. That is especially important when the tire is supporting heavier loads and daily utility use.
