The 1997 GMC Trucks K3500 comes from an era when heavy-duty pickups had to balance real work capability with everyday drivability, and the K3500 remains a practical choice for owners who still use these trucks for hauling, towing, and utility duty. Tire selection on this model centers on two 16-inch radial sizes, with 245/75R16 used on single-rear-wheel Sierra trims and 225/75R16 used on dual-rear-wheel front and rear positions. That makes the main decision less about era-correct styling and more about matching the truck's exact wheel setup, load needs, and intended use. For many owners, confirming whether the truck is SRW or DRW is the first and most important step.
Which Tire Size Is Right for The 1997 GMC Trucks K3500
The 1997 GMC Trucks K3500 uses two primary tire sizes, and the right one depends on the truck's exact wheel configuration. Both sizes are radial tires for 16-inch rims, but 245/75R16 applies to single-rear-wheel Sierra trims while 225/75R16 is used on dual-rear-wheel front and rear positions. Before selecting a tire, identify whether the truck is SRW or DRW and confirm the wheel setup currently on the vehicle.
245/75R16 is a metric radial size in which 245 identifies the section width in millimeters, 75 is the aspect ratio, R denotes radial construction, and 16 is the rim diameter in inches. On the 1997 GMC Trucks K3500, this size is used on single-rear-wheel Sierra SL, SLE, and SLT models. Available examples in this size use BFGoodrich's All-Terrain T/A KO2 series with a raised white letter sidewall. This size is the one to evaluate when the truck retains its SRW layout and the goal is to match the proper 16-inch heavy-duty pickup fitment.
Fit(s): Sierra SL (DRW) Front, Sierra SL (DRW) Rear, Sierra SLE (DRW) Front, Sierra SLE (DRW) Rear, Sierra SLT (DRW) Front, and Sierra SLT (DRW) Rear
Construction: Radial|Rim: 16 in
225/75R16 is also a metric radial size, with 225 representing section width in millimeters, 75 indicating the sidewall profile, R showing radial construction, and 16 identifying the wheel diameter. On the 1997 GMC Trucks K3500, this size is tied to dual-rear-wheel configurations and is used on DRW front and rear positions in Sierra SL, SLE, and SLT form. BFGoodrich offers this size in the All-Terrain T/A KO2 line with a raised white letter sidewall. It is the size to focus on when the truck has a dually wheel arrangement and needs the narrower tire that setup requires.
Sub-model fitment on the 1997 GMC Trucks K3500 depends primarily on whether the truck is single rear wheel or dual rear wheel. Trim level alone does not change the pattern, so the important check is the truck's actual wheel configuration before choosing a tire.

1997 GMC Trucks K3500 Sierra SL
The Sierra SL uses the 245/75R16 radial size in single-rear-wheel form. That keeps tire selection straightforward, with the main checks being 16-inch wheel fitment, load needs, and whether the truck still has its original SRW setup.
The Sierra SL (DRW) Front uses the 225/75R16 radial size. For a dually truck, that means confirming the front wheel still matches the original 16-inch DRW arrangement before selecting a tire in this narrower size.
The Sierra SL (DRW) Rear also uses 225/75R16 radial tires. Rear dually fitment makes wheel confirmation especially important, since the tire choice needs to suit the rear dual-wheel setup rather than a single-rear-wheel conversion.
The Sierra SLE uses 245/75R16 in radial construction on its single-rear-wheel configuration. Tire choice in this sub-model centers on staying with the correct SRW size and matching it to the truck's current wheel and usage requirements.
The Sierra SLE (DRW) Front uses 225/75R16 radial tires. That makes the key decision less about trim level and more about confirming the front dually wheel setup before comparing available tires.
The Sierra SLE (DRW) Rear uses the same 225/75R16 radial fitment as the front dually position. Owners should verify that the rear wheels and spacing still reflect the proper DRW configuration before choosing a replacement tire.
The Sierra SLT uses 245/75R16 radial tires in single-rear-wheel form. That points the selection process toward the correct SRW size first, then into practical details such as rim-width compatibility and intended truck use.
The Sierra SLT (DRW) Front uses 225/75R16 radial tires on a 16-inch dually wheel setup. Choosing the right tire starts with confirming that the front axle still carries the proper DRW wheel arrangement.
The Sierra SLT (DRW) Rear uses 225/75R16 radial tires as part of the rear dual-wheel arrangement. Rear tire selection should be made around the actual dually setup on the truck, not simply the trim badge.
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 1997 GMC Trucks K3500 Tires for Sale
Available 1997 GMC Trucks K3500 tires center on BFGoodrich All-Terrain T/A KO2 options in both 245/75R16 and 225/75R16. The current choices share radial construction and raised white letter sidewalls, with rim-width and load specifications that differ by size and wheel configuration.
These 1997 GMC Trucks K3500 tire FAQs focus on the key questions owners usually face: SRW versus DRW size selection, 16-inch rim fitment, available tire choices, and the checks that matter before putting a working or collector-era heavy-duty truck back on the road.
Tire Size & Fitment
What tire size fits a 1997 GMC Trucks K3500?
The 1997 GMC Trucks K3500 uses two primary tire sizes: 245/75R16 and 225/75R16. The 245/75R16 size is used on single-rear-wheel Sierra SL, SLE, and SLT models, while 225/75R16 is used on dual-rear-wheel front and rear positions for DRW versions of those same trims.
The practical question is not simply the model year and trim name, but whether the truck is set up as SRW or DRW. A K3500 that has had wheel or axle changes over the years should be checked carefully, because the correct size depends on the actual wheel arrangement on the truck today.
What size rim does a 1997 GMC Trucks K3500 use?
Both primary tire sizes for the 1997 GMC Trucks K3500 use a 16-inch rim diameter. That applies to the 245/75R16 size used on single-rear-wheel versions and the 225/75R16 size used on dual-rear-wheel configurations.
Wheel diameter is only part of the fitment picture on a heavy-duty truck like the K3500. Rim width also matters, and the available tires in these sizes have different rim-width ranges, so it is worth checking the actual wheel before selecting a replacement, especially on trucks that have seen work use or aftermarket wheel changes.
Do all 1997 GMC Trucks K3500 sub-models use the same tire size?
No. The 1997 GMC Trucks K3500 uses different tire sizes depending on whether the truck is single rear wheel or dual rear wheel. Sierra SL, SLE, and SLT SRW models use 245/75R16, while DRW front and rear positions use 225/75R16.
That means trim level by itself is not enough to choose a tire. A buyer should verify whether the truck is a dually or a single-rear-wheel setup, then confirm that the current wheels match that configuration, since many older work trucks have been modified or had replacement wheels installed during their service life.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 or 225/75R16 tire for a 1997 GMC Trucks K3500?
Start with the correct size for the truck's wheel configuration. A 1997 GMC Trucks K3500 in SRW form uses 245/75R16, while DRW front and rear positions use 225/75R16. Both are radial 16-inch sizes, but they are not serving the same application on the truck.
After size, compare practical details such as rim-width compatibility, load capacity, and the truck's intended use. A heavy-duty pickup used for towing, hauling, or occasional off-pavement driving places different demands on a tire than a lightly used collector truck, so the wheel setup and planned use should guide the final selection.
What sidewall styles are available for 1997 GMC Trucks K3500 tires?
The available 1997 GMC Trucks K3500 tires here use an RWL sidewall, meaning raised white letters. That sidewall treatment appears on both the 245/75R16 and 225/75R16 BFGoodrich All-Terrain T/A KO2 options.
Raised white letters give the truck a more traditional light-truck performance and utility look than a plain black sidewall. Appearance still needs to come second to proper fitment, though, so the better approach is to confirm the correct SRW or DRW size first and then decide whether the available sidewall presentation suits the truck's intended character.
What brands offer tires for the 1997 GMC Trucks K3500?
BFGoodrich is the brand represented in the current 1997 GMC Trucks K3500 tire selection, with All-Terrain T/A KO2 options available in both 245/75R16 and 225/75R16. Those cover the truck's SRW and DRW fitment needs within the supported 16-inch radial sizes.
That makes the buying decision more about choosing the right size and confirming wheel compatibility than comparing multiple brand personalities. Owners should still review details such as rim-width range, load rating at the stated pressure, and how the truck is used, since those factors matter more than brand variety on a work-oriented heavy-duty pickup.
Restoration & Appearance
Which tire should I choose for a period-style 1997 GMC Trucks K3500?
A period-style approach starts with the truck's correct original fitment pattern: 245/75R16 for single-rear-wheel models and 225/75R16 for dual-rear-wheel front and rear positions. Since this K3500 is already in the modern radial era, staying with the proper radial size is usually the right foundation for an authentic late-1990s heavy-duty truck presentation.
Appearance decisions then come down to details such as sidewall treatment and overall tire character. The available raised white letter all-terrain look can suit many trucks from this period, but owners focused on strict restoration standards should compare the truck against period photos, dealer literature, or marque-specific references before deciding on final appearance details.
Does correct tire fitment matter for a 1997 GMC Trucks K3500 restoration?
Yes, correct tire fitment matters on a 1997 GMC Trucks K3500 restoration because wheel configuration is part of the truck's visual stance and working character. A single-rear-wheel truck on 245/75R16 tires presents differently from a dually using 225/75R16 at the front and rear, and mixing those patterns can quickly change the truck's proportions.
Fitment also affects how convincing and usable the finished truck feels. Restoring the right size on the right 16-inch wheel helps preserve proper clearance and load-focused setup, while a casual size substitution can create avoidable issues in appearance or function. Confirming the truck's actual SRW or DRW configuration should come before cosmetic decisions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1997 GMC Trucks K3500?
Yes. Modifications can change tire fitment on a 1997 GMC Trucks K3500 even when the truck still appears stock at a glance. Aftermarket wheels, suspension lifts, ride-height changes, axle swaps, or a conversion between single-rear-wheel and dual-rear-wheel setups can all alter which tire size makes sense for the truck.
That is why wheel diameter, rim width, and actual wheel arrangement should be checked before replacing tires. On an older heavy-duty pickup, it is also smart to inspect for fender, steering, or suspension clearance changes that may have come from previous work-truck use rather than from a clearly documented modification.
What should I inspect before driving a 1997 GMC Trucks K3500 on new tires?
Before road use, inspect the wheels for damage, verify proper tire pressure, and make sure the installed tires match the truck's correct SRW or DRW configuration. It is also worth checking tread seating, valve stems, and general wheel condition, especially on a K3500 that has spent years in work service or long-term storage.
A short test drive should be used to watch for rubbing, unusual steering feel, vibration, or any sign that the wheel setup is not matched correctly to the tire size. Heavy-duty trucks also deserve a close look at suspension wear and alignment condition, since worn front-end parts can affect how a fresh set of tires performs.
How should 245/75R16 and 225/75R16 tires on a collector-era 1997 GMC Trucks K3500 be maintained?
Regular maintenance starts with keeping the tires properly inflated, inspecting them for cracking, cuts, bulges, and uneven wear, and checking for slow air loss during periods of storage. On a 1997 GMC Trucks K3500, that routine matters whether the truck runs 245/75R16 in SRW form or 225/75R16 in a DRW setup.
Older trucks that are driven infrequently still need scheduled inspections because tire condition can deteriorate with age even when tread looks usable. Storage away from prolonged sunlight, heat, and moisture helps, and a truck brought back into service should have its tires, wheels, and pressures checked carefully before any longer highway or towing trip.
