2012 GMC Vans Tire Fitment Guide

2012 GMC Vans use two tire sizes across the Savana lineup: 245/70R17 for the Savana 1500, and 245/75R16 for the Savana 2500 and Savana 3500. Both are radial sizes, but they do not share the same wheel diameter. The 245/70R17 mounts on a 17-inch rim, while the 245/75R16 mounts on a 16-inch rim. Both available products fit rim widths from 6.5 to 8.0 inches.

That means identifying the van's series matters before anything else. A buyer with a Savana 1500 should start with 17-inch wheel fitment, while a Savana 2500 or 3500 owner should start with 16-inch wheel fitment. If the van has replacement wheels, confirm the actual wheel diameter and width on the van before choosing a tire, because the two sizes are not interchangeable across the full 2012 GMC Vans range.

On a 2012 GMC Vans tire, 245/70R17 means the tire is 245 millimeters wide, has a 70-series aspect ratio, and is built in radial construction for a 17-inch wheel. Within the Savana range, that size belongs to the Savana 1500. The available product in this size carries an S speed rating, which corresponds to a maximum speed capability of 112 mph under rated conditions.

For a Savana 1500 owner, that code tells you far more than width alone. It confirms both the sidewall profile and the wheel diameter the tire is built around, so matching only the width and ignoring the 17-inch rim requirement would be a mistake. It is also wise to confirm that your wheel falls within the tire's 6.5- to 8.0-inch rim width range before settling on a replacement.

On a 2012 GMC Vans tire, 245/75R16 means the tire is 245 millimeters wide, uses radial construction, carries a 75-series aspect ratio, and fits a 16-inch wheel. That size applies to the Savana 2500 and Savana 3500. The available product in this size also carries an S speed rating, which has a 112 mph ceiling under rated conditions.

The practical value of reading the code correctly is that it separates the heavier-duty Savana fitment from the lighter-duty 1500 fitment. Even though both sizes begin with 245, they are built for different wheel diameters and different sidewall proportions. If your 2500 or 3500 has stayed close to factory wheel sizing, 245/75R16 is the place to start; if the wheels have been changed, verify the actual rim before ordering.

BFGoodrich covers both tire sizes used on 2012 GMC Vans. The Savana 1500's 245/70R17 fitment is available in the BFGoodrich All-Terrain T/A KO2 series, and the Savana 2500 and 3500's 245/75R16 fitment is also available in the BFGoodrich All-Terrain T/A KO2 series. Both fitments are radial and use an RWL sidewall style.

That creates a straightforward choice for owners who want a consistent brand across different Savana series, but it does not eliminate the need to match the correct size to the van. A 1500 owner still needs the 17-inch fitment, while 2500 and 3500 owners need the 16-inch fitment. Once the size is confirmed, the remaining considerations are wheel width compatibility and how the tire's all-terrain character aligns with the van's use.

2012 GMC Vans tire options here use an RWL, or raised white letter, sidewall style in both available sizes. The 245/70R17 for the Savana 1500 and the 245/75R16 for the Savana 2500 and 3500 share that same sidewall treatment. That gives the lineup a more assertive truck-style appearance than a plain blackwall tire.

For many owners, sidewall style is partly about appearance and partly about how closely the tire matches the van's intended personality. An RWL sidewall tends to suit a utility-focused van, especially one with a more rugged visual theme. If presentation matters, check whether you want the white letters facing outward or inward, and confirm how that look fits the rest of the van before making the final choice.

The BFGoodrich All-Terrain T/A KO2 appears in two different sizes for 2012 GMC Vans, and the difference is fitment rather than brand or series. The Savana 1500 uses LT245/70R17/E with a 3,000-pound load capacity at 80 psi and a 47-pound tire weight. The Savana 2500 and 3500 use LT245/75R16/E with a 3,042-pound load capacity at 80 psi and a 48-pound tire weight.

In practical terms, the decision is driven by which Savana model you own and which wheel diameter is on the van. The 17-inch version belongs with the 1500, while the 16-inch version belongs with the 2500 and 3500. Since both sizes share the same 6.5- to 8.0-inch rim width range and the same S speed rating, the key is matching the tire to the correct wheel and vehicle series rather than comparing one as broadly superior to the other.

The two tire sizes used on 2012 GMC Vans share the same approved rim width range in the available products. Both 245/70R17 for the Savana 1500 and 245/75R16 for the Savana 2500 and 3500 fit rims from 6.5 to 8.0 inches wide. The difference between the sizes is rim diameter, not the width range they accept.

That makes wheel-width checking fairly simple, especially if your van still uses stock-style wheels. Even so, width should still be verified before mounting because aftermarket wheels can change both diameter and width. A buyer who confirms both dimensions up front avoids common fitment mistakes such as choosing the right tire size code for the van but pairing it with a wheel outside the approved width range.

The available 2012 GMC Vans tire products do not carry a tube-type marking, and both fitments are modern radial light-truck tires. That points to tubeless use in normal applications on suitable tubeless wheels. The 245/70R17 and 245/75R16 fitments are both part of that same modern radial pattern.

The practical check is not just the tire itself but the wheel condition and wheel type. If your Savana still has standard later-model van wheels in sound condition, tubeless fitment is the expected setup. If the van has specialty wheels, repaired wheels, or wheels of uncertain condition, inspect the bead seats and valve stem area carefully before mounting so the tire and wheel are working together as intended.

Original 2012 GMC Vans wheels cannot be treated as universal across all Savana models because the tire sizes use different rim diameters. The Savana 1500 size, 245/70R17, requires a 17-inch wheel, while the Savana 2500 and 3500 size, 245/75R16, requires a 16-inch wheel. Both sizes fit wheels in a 6.5- to 8.0-inch width range, but the diameter difference is decisive.

That means a 1500 owner should not assume a 2500 or 3500 wheel-and-tire package will interchange cleanly, or vice versa, without a full wheel and vehicle compatibility review. Start by verifying the wheel diameter actually on the van, then confirm width. If your Savana has had wheel changes over the years, checking the stamped wheel specs or measuring directly is the safest way to avoid a mismatch.

A stored 2012 GMC Vans should be kept away from direct sunlight, standing moisture, and ozone sources such as electric motors, battery chargers, and welders. Tire pressures should be maintained during storage, and the van should be moved periodically so the same tread area is not carrying the load month after month. These are modern radial tires, so they generally tolerate storage better than older bias-ply designs, but long static periods still age rubber.

Owners who store a Savana for seasonal use or low annual mileage should make tire care part of the storage routine rather than an afterthought. Clean the tires, keep them out of weather, and inspect them before the van goes back into service. If the van will sit for a very long period, reducing continuous load on one contact patch can help preserve shape and ride quality when it returns to the road.

Tires on a 2012 GMC Vans should be judged by age as much as by tread depth, especially on a van that sees limited seasonal or hobby use. A good rule is to begin careful evaluation around the five- to seven-year point and to treat about ten years from the DOT date code as a point where replacement deserves serious consideration, even if the tread still looks serviceable.

That approach matters because many low-mileage vans age out their tires before they wear them out. Sidewall cracking, hardening rubber, and loss of flexibility can appear long before the tread is gone. Check the DOT date code on each tire, not just the spare, and weigh age together with condition, storage history, and how confidently you expect the van to handle longer trips or sustained highway use.

Tires on a 2012 GMC Vans should be inspected before every drive and given a more thorough check before any extended outing. Look for sidewall cracking, cuts, bulges, irregular wear, embedded objects, and signs of pressure loss. Because these are tubeless radial light-truck tires, valve stem condition and bead-seat sealing are also worth checking closely on a vehicle that may sit for stretches.

A quick walk-around catches many problems before they become roadside issues. Heavier-duty vans such as the Savana 2500 and 3500 also benefit from close pressure checks because load-carrying ability depends on maintaining the correct inflation range for the tire. If a tire has lost pressure more than once, inspect the wheel and valve hardware along with the tire itself rather than simply airing it back up and moving on.

The available 2012 GMC Vans tires are radial light-truck tires with S speed ratings, which carry a 112 mph maximum speed capability under rated conditions. That is well beyond ordinary U.S. highway speeds, so the tires themselves are not the limiting factor for routine road use when they are in good condition and properly inflated. On a full-size van, loading, alignment, suspension condition, and brake condition often matter just as much as the speed symbol on the sidewall.

Highway safety comes from the whole package working together. Confirm that the tire size matches the van, that the load range suits how the van is used, and that inflation is appropriate for the service. A Savana used for cargo or passenger duty should also have its tires inspected for age and wear before longer trips, because an older tire can become the weak point even when its speed rating looks more than adequate on paper.

The available 245/70R17 tire for the 2012 GMC Vans Savana 1500 is rated at 3,000 pounds at 80 psi, and the available 245/75R16 tire for the Savana 2500 and 3500 is rated at 3,042 pounds at 80 psi. Those figures are tire ratings, not blanket instructions to run every van at maximum pressure in every driving condition. Factory vehicle pressure recommendations should still come from the van's placard or owner's manual.

Use the vehicle recommendation as the starting point, then confirm that the tire's own rated pressure and load range align with your intended use. Do not transfer a pressure figure from the 17-inch Savana 1500 fitment to the 16-inch 2500 and 3500 fitment, or the other way around, simply because the section width is similar. Matching pressure to the correct size and the van's real operating load is the sound approach.

Before taking a 2012 GMC Vans on a longer drive, inspect each tire for cracking, cuts, tread damage, punctures, bulges, and uneven wear. Check cold inflation pressure, look over the valve stems, and make sure the spare is present and serviceable. Since the Savana lineup uses two different wheel diameters depending on model, it is also worth confirming that the spare matches the van's actual fitment.

Tires are only one part of a longer-trip check, but they are one of the easiest places to catch trouble early. A van that has sat for a while can have aged tires even when the tread looks deep, and a work van can hide uneven wear if alignment or suspension parts are tired. Giving the tires a careful inspection before departure helps you decide whether the van is ready for miles or needs attention first.
