The 1996 GMC Vans G3500 comes from the final era of the traditional full-size rear-drive GMC van, a platform valued for its work capability, conversion-van appeal, and durable long-wheelbase utility. Buyers looking at one today are often balancing practical road use with the need to keep the van's stance and load-carrying character appropriate to the exact configuration. Tire fitment centers on two 16-inch radial sizes, 225/75R16 and 245/75R16, with the larger size tied to a specific Vandura variant. Available choices focus less on vintage-style presentation and more on correct size, load capacity, and wheel compatibility for the way the van is actually equipped and driven.
Which Tire Size Is Right for The 1996 GMC Vans G3500
The 1996 GMC Vans G3500 uses two primary tire sizes, and the correct choice depends on the exact sub-model. Both are radial tires for 16-inch rims, but most Rally and Vandura versions use 225/75R16, while the Vandura (GMT 600) uses 245/75R16. The first step is confirming the van's specific trim and wheel setup before comparing load capacity, rim-width compatibility, and product details.
225/75R16 is a metric radial size in which 225 represents the section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 16 is the rim diameter in inches. On the 1996 GMC Vans G3500, this is the primary fitment for most covered Rally and Vandura sub-models. Available tires in this size include a BFGoodrich All-Terrain T/A KO2 with raised white letter styling. This size is the right starting point when the van retains the standard 16-inch setup used on the majority of G3500 configurations shown here.
245/75R16 follows the same metric radial format, but with a wider 245-millimeter section width paired with a 75-series profile on a 16-inch rim. For the 1996 GMC Vans G3500, this size is associated with the Vandura (GMT 600) rather than the full range of sub-models. The available BFGoodrich All-Terrain T/A KO2 in this size also uses raised white letters and carries a higher stated load capacity than the smaller size. It is the size to evaluate when the van is the GMT 600 variant or already equipped with the corresponding wheel and tire package.
Sub-model fitment matters on the 1996 GMC Vans G3500 because most versions share one tire size, while one covered Vandura variant uses a larger alternative. Checking the exact sub-model helps separate a straightforward replacement from a size decision that affects wheel compatibility and overall tire dimensions.

1996 GMC Vans G3500 Rally
The 1996 GMC Vans G3500 Rally uses the 225/75R16 radial tire size on a 16-inch rim. Tire selection here is mainly about staying with the correct metric radial fitment and comparing product details such as load specification, sidewall appearance, and rim-width compatibility.
The 1996 GMC Vans G3500 Rally STX also uses the 225/75R16 radial size. That keeps replacement straightforward, with the main task being confirmation that the van still has the intended wheel setup before choosing among available tires in that size.
The 1996 GMC Vans G3500 Rally STX w/H.D. Suspension uses the same 225/75R16 radial fitment. Even with the heavy-duty suspension designation, the tire decision remains centered on the correct size, 16-inch wheel compatibility, and the load-carrying characteristics of the tire being considered.
The 1996 GMC Vans G3500 Rally w/H.D. Suspension is fitted with 225/75R16 radial tires. That means the key buying considerations are proper replacement sizing, wheel-width suitability, and making sure the current wheels and suspension setup have not been changed from the intended configuration.
The 1996 GMC Vans G3500 Vandura uses the 225/75R16 radial size rather than the larger alternative found on one specific variant. For this sub-model, tire selection is mostly a matter of keeping the correct overall fitment while comparing available load and rim-width specifications.
The 1996 GMC Vans G3500 Vandura (G-Classic) uses 225/75R16 radial tires. That keeps fitment consistent with most other covered G3500 versions, so the buyer's attention can stay on wheel compatibility, intended use, and the character of the available tire choice.
The 1996 GMC Vans G3500 Vandura (G-Classic) H.D. uses the 225/75R16 radial size. Choosing a tire for this version means confirming the van still carries the proper 16-inch wheel setup and selecting a tire whose specifications suit the van's working or passenger-carrying role.
The 1996 GMC Vans G3500 Vandura (GMT 600) uses the larger 245/75R16 radial size. That makes this sub-model the one that needs the closest size verification, especially if the van has seen wheel changes or mixed service over time.
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.
Best 1996 GMC Vans G3500 Tires for Sale
Available 1996 GMC Vans G3500 tires center on BFGoodrich All-Terrain T/A KO2 options in both primary sizes. Comparison points are straightforward: 225/75R16 versus 245/75R16, raised white letter sidewalls, radial construction, and the different rim-width and load specifications tied to each size.
Owners of a 1996 GMC Vans G3500 usually need clear answers on the correct tire size by sub-model, 16-inch rim fitment, available radial choices, and what to inspect before putting a heavy full-size van back on the road.
Tire Size & Fitment
What tire size fits a 1996 GMC Vans G3500?
A 1996 GMC Vans G3500 uses either 225/75R16 or 245/75R16, depending on the sub-model. Most covered Rally and Vandura versions use 225/75R16, while the 1996 GMC Vans G3500 Vandura (GMT 600) uses 245/75R16. Both are radial tires sized for 16-inch rims.
The practical step is identifying the exact van configuration before ordering tires. A G3500 that has had wheel changes, suspension work, or years of mixed service may no longer match its original setup, so the current wheel diameter, wheel width, and tire clearance should be checked along with the sub-model name.
What size rim does a 1996 GMC Vans G3500 use?
The covered tire fitments for the 1996 GMC Vans G3500 use a 16-inch rim diameter. That is true for both 225/75R16 and 245/75R16, even though the two tire sizes differ in section width and overall dimensions.
Rim diameter is only part of the fitment picture, especially on a heavy-duty full-size van. Wheel width also matters, and the available tires in these sizes are paired with different rim-width ranges, so a 16-inch wheel should still be measured and confirmed rather than assumed correct solely from diameter.
Why does the 1996 GMC Vans G3500 have more than one tire size?
The 1996 GMC Vans G3500 has more than one tire size because fitment changes by sub-model. Most covered versions use 225/75R16, while the Vandura (GMT 600) uses the wider 245/75R16, so the size difference reflects configuration rather than a universal choice for every G3500 van.
That distinction matters because two 16-inch tires can still place different demands on wheel width and clearance. A buyer should confirm the exact sub-model first, then compare the current wheel setup and the tire already on the van before treating one size as an acceptable substitute for the other.
Choosing the Right Tire
What should I consider when choosing a 1996 GMC Vans G3500 tire?
Start with the correct primary size for the van's exact sub-model: 225/75R16 for most covered versions or 245/75R16 for the Vandura (GMT 600). From there, the main considerations are radial construction, 16-inch rim compatibility, load capacity, and whether the tire's intended use matches a working, hauling, or mixed-use full-size van.
A useful comparison goes beyond the size molded on the sidewall. Wheel width, the van's current stance, and how much weight it carries should all be checked, especially on an older G3500 that may have had replacement wheels or suspension work during its service life.
What sidewall styles are available for 1996 GMC Vans G3500 tires?
The available products for the covered 1996 GMC Vans G3500 tire sizes use an RWL sidewall, meaning raised white letters. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options offered in both 225/75R16 and 245/75R16.
Raised white letters give the van a more truck-oriented appearance than a plain blackwall, which may matter on a Rally, Vandura, or conversion-style build. Sidewall style does not override fitment, so the size, wheel compatibility, and intended use should still be settled first before appearance becomes the deciding factor.
What brands offer tires for the 1996 GMC Vans G3500?
The available tire choices for the covered 1996 GMC Vans G3500 fitments come from BFGoodrich. Both primary sizes, 225/75R16 and 245/75R16, are represented by the BFGoodrich All-Terrain T/A KO2 in radial construction.
With a single brand represented here, the real comparison shifts to size selection, load specification, and wheel-width suitability rather than cross-shopping multiple brand lines. That makes it especially important to verify which G3500 sub-model is being fitted and whether the van still carries the correct 16-inch wheel package.
Restoration & Appearance
Which tire should I choose for a period-style 1996 GMC Vans G3500?
A period-style approach for a 1996 GMC Vans G3500 still begins with the correct primary size for the exact sub-model. Most covered versions use 225/75R16, while the Vandura (GMT 600) uses 245/75R16, and both fitments are radial rather than bias-ply.
Because this is a 1990s full-size van, appearance decisions are usually more about maintaining the right stance and utility-focused look than recreating an early collector-car tire treatment. Keeping the proper size and wheel relationship matters more than forcing a different tire profile that changes how the van sits.
How does tire construction affect the appearance of a restored 1996 GMC Vans G3500?
On a 1996 GMC Vans G3500, the primary fitments are radial tires, so the overall look is already tied to a modern radial profile on a 16-inch wheel. That gives the van a more contemporary commercial or utility appearance than an earlier vintage vehicle built around bias-ply proportions.
Visual character comes more from correct sizing and sidewall treatment than from a bias-ply-versus-radial decision on this application. A tire that is too wide, too tall, or paired with the wrong wheel can change the van's stance noticeably, even when the construction type remains appropriate to the era.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1996 GMC Vans G3500?
Yes. Modifications such as aftermarket wheels, suspension changes, ride-height adjustments, or body alterations can affect tire fitment on a 1996 GMC Vans G3500 even when the tire size sounds close on paper. That matters with both 225/75R16 and 245/75R16 because each size has its own width and dimensional profile.
A van that has been lowered, lifted, or fitted with different wheels should be checked for steering clearance, wheel width, and room at the fenders and suspension components. Older full-size vans often accumulate changes over time, so present-day measurements are more useful than assumptions based on model name alone.
What should I inspect before driving a 1996 GMC Vans G3500 on new tires?
Before driving a 1996 GMC Vans G3500 on new tires, inspect the wheels for the correct 16-inch diameter and suitable width, then confirm the tires are the right size for the sub-model. Lug hardware, valve stems, inflation pressure, and visible clearance at the steering and suspension should also be checked.
An older G3500 may also need attention beyond the tire itself. Uneven wear patterns, wandering, or rubbing can point to alignment issues, worn steering parts, tired springs, or brake and bearing concerns, so a short inspection drive and a careful recheck after installation are worthwhile.
How should 225/75R16 or 245/75R16 tires on a collector 1996 GMC Vans G3500 be maintained?
225/75R16 and 245/75R16 tires on a collector 1996 GMC Vans G3500 should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long periods of sun, moisture, and ozone exposure during storage. Regular movement also helps prevent long-term flat spotting on low-use vehicles.
Maintenance should match how the van is actually used. A G3500 that carries weight, tows, or sees highway travel deserves closer attention to air loss and tread condition than one that appears only occasionally, and any sign of vibration or pull should prompt a wheel, balance, and front-end check.
