The 2000 GMC Trucks Sierra 1500 comes from a period when full-size pickups were expected to balance daily usability, towing confidence, and a more refined highway ride than earlier generations. That makes tire selection especially important, because this Sierra 1500 uses several 16-inch radial sizes depending on trim and driveline, including 235/75R16, 255/70R16, 245/75R16, and 265/75R16. Available choices here center on BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls. The key is confirming whether the truck is a 4x2 or 4x4, then choosing the size and tire character that match the truck's current wheel setup and intended use.
Which Tire Size Is Right for The 2000 GMC Trucks Sierra 1500
The 2000 GMC Trucks Sierra 1500 uses four primary tire sizes, and the right one depends on the truck's exact sub-model and whether it is a 4x2 or 4x4. All of these are radial tires for 16-inch rims, so the main job is identifying the truck's configuration first, then confirming which of the two applicable sizes belongs on that setup before comparing tire details.
A 235/75R16 tire uses a 235-millimeter nominal section width, a 75-series aspect ratio, radial construction, and a 16-inch rim diameter. On the 2000 GMC Trucks Sierra 1500, this size is one of the primary 4x2 fitments and reflects a traditional light-truck sizing format with a relatively tall sidewall. It should be evaluated as part of the correct 4x2 setup rather than as a universal Sierra 1500 size. This is the right place to start if the truck remains on its original-style 16-inch wheel diameter and has not been changed to a different wheel or suspension package.
A 255/70R16 tire has a 255-millimeter nominal section width, a 70-series profile, radial construction, and it mounts on a 16-inch wheel. For the 2000 GMC Trucks Sierra 1500, this is another 4x2 fitment, offering a wider modern metric size while staying on the same rim diameter. In the available product selection, this size appears in the BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. It is best suited to owners who have confirmed that their 4x2 truck uses this wider 16-inch size rather than the narrower 235/75R16 alternative.
A 245/75R16 tire combines a 245-millimeter nominal section width with a 75-series sidewall, radial construction, and a 16-inch rim diameter. On the 2000 GMC Trucks Sierra 1500, this size belongs with 4x4 applications and keeps a taller sidewall profile than a lower-series alternative. Available products in this size include the BFGoodrich All-Terrain T/A KO2 with raised white letter styling. This size makes the most sense after the truck's 4x4 configuration and actual wheel setup have been confirmed, especially if the truck has seen changes in wheels, ride height, or suspension components.
A 265/75R16 tire uses a 265-millimeter nominal section width, a 75-series profile, radial construction, and a 16-inch wheel diameter. For the 2000 GMC Trucks Sierra 1500, it is one of the 4x4 tire sizes and represents the largest primary fitment used across the covered sub-models. In the current product range, this size is available as a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. It is worth considering only after confirming that the truck's 4x4 trim and wheel width match this size, since not every Sierra 1500 configuration uses it.
Tire fitment for the 2000 GMC Trucks Sierra 1500 varies by sub-model, and the biggest dividing line is 4x2 versus 4x4. Confirming the exact trim and driveline matters because each covered sub-model uses one of two different 16-inch radial size pairs.

2000 GMC Trucks Sierra 1500 SL 4x2
The 2000 GMC Trucks Sierra 1500 SL 4x2 uses the same pair of 16-inch radial sizes found on the other 4x2 trims. That makes tire selection a matter of confirming which of those two 4x2 sizes is on the truck now, then matching the wheel setup and intended use.
The 2000 GMC Trucks Sierra 1500 SL 4x4 shares its tire-fitment pattern with the other 4x4 sub-models, using one of two 16-inch radial sizes. Tire choice should start with the exact size already fitted to the truck and a quick check for any wheel or suspension changes that could affect selection.
The 2000 GMC Trucks Sierra 1500 SLE 4x2 follows the same 16-inch radial fitment pattern used by the other 4x2 versions. The practical decision is choosing the correct current size on the truck, then comparing tire style and intended use within that fitment.
The 2000 GMC Trucks Sierra 1500 SLE 4x4 uses the same two 16-inch radial fitments shared by the covered 4x4 trims. That means the important step is verifying which of those sizes belongs on the truck's present wheel setup before selecting a tire.
The 2000 GMC Trucks Sierra 1500 SLT 4x2 uses the same 16-inch radial size pattern as the other 4x2 models in this range. Buyers should confirm the exact size mounted on the truck, then choose the tire that best suits its road use and appearance preferences.
The 2000 GMC Trucks Sierra 1500 SLT 4x4 shares the same 16-inch radial fitments used across the listed 4x4 Sierra 1500 trims. Selecting the right tire starts with confirming the truck's current 4x4 size and making sure the wheels still match that specification.
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 2000 GMC Trucks Sierra 1500?
The 2000 GMC Trucks Sierra 1500 uses four primary tire sizes: 235/75R16, 255/70R16, 245/75R16, and 265/75R16. All are radial tires for 16-inch wheels, but they do not apply across every Sierra 1500 configuration. The correct choice depends on whether the truck is a 4x2 or 4x4 and which sub-model you are matching.
A quick look at the tire sidewall and the truck's exact trim is the best starting point before ordering replacements. Trucks that have had wheel changes, leveling kits, or suspension work may no longer be running the original fitment, so the mounted size and actual wheel width should both be verified.
What size rim does a 2000 GMC Trucks Sierra 1500 use?
The covered tire sizes for the 2000 GMC Trucks Sierra 1500 all use a 16-inch rim diameter. That includes 235/75R16, 255/70R16, 245/75R16, and 265/75R16, so the common fitment point across the range is a 16-inch wheel rather than multiple rim diameters.
Rim diameter is only one part of the fitment picture, so it should not be the only check. Wheel width also matters, especially when moving among the wider Sierra 1500 sizes, and any aftermarket wheels should be measured carefully before choosing a replacement tire.
Do all 2000 GMC Trucks Sierra 1500 sub-models use the same tire size?
No. The 2000 GMC Trucks Sierra 1500 sub-models do not all use the same tire size, even though they all stay on 16-inch radial tires. The 4x2 models use 235/75R16 or 255/70R16, while the 4x4 models use 245/75R16 or 265/75R16.
That means the trim badge alone is not enough unless the driveline is also confirmed. A Sierra 1500 SL, SLE, or SLT can point you in the right group, but the final check should always be the truck's 4x2 or 4x4 configuration and the size already mounted on the wheels.
Choosing the Right Tire
What should I consider when choosing a tire for a 2000 GMC Trucks Sierra 1500?
Start with the correct primary size for the truck's exact 4x2 or 4x4 configuration, since the 2000 GMC Trucks Sierra 1500 uses four different 16-inch radial sizes. After that, compare the tire's intended character, rim-width compatibility, load capacity, and whether the truck's current use is more highway, mixed-duty, or all-terrain oriented.
It also helps to confirm whether the truck still has its original wheel setup or has been modified over time. A Sierra 1500 that has aftermarket wheels, suspension changes, or a different tire size already installed should be checked carefully so the replacement tire matches both the vehicle's fitment needs and its real-world use.
What sidewall styles are available for 2000 GMC Trucks Sierra 1500 tires?
The available products for the covered 2000 GMC Trucks Sierra 1500 sizes use RWL sidewalls, which is the familiar raised white letter look. That gives the truck a more traditional light-truck appearance than a plain blackwall and pairs naturally with an all-terrain tire presentation.
Sidewall style is mostly an appearance choice once the correct size and wheel fitment have been settled. Raised white letters can suit a truck with a more period-truck or utility-oriented look, but the size, wheel compatibility, and intended driving conditions still matter more than sidewall styling alone.
What brands offer tires for the 2000 GMC Trucks Sierra 1500?
The available products for the covered 2000 GMC Trucks Sierra 1500 sizes come from BFGoodrich. The current selection centers on the All-Terrain T/A KO2 series in the applicable 16-inch radial truck sizes, making brand choice straightforward but still leaving important fitment and specification differences between sizes.
Since the available brand selection is focused, the real comparison becomes size, rim-width range, weight, and load capacity rather than brand-versus-brand shopping. Matching the truck's exact 4x2 or 4x4 fitment remains the first step, especially because not every Sierra 1500 size has the same wheel-width needs.
Restoration & Appearance
Which tire should I choose for a period-style 2000 GMC Trucks Sierra 1500?
For a period-style 2000 GMC Trucks Sierra 1500, the best starting point is the truck's correct original-type size category within its 16-inch radial fitment. A 4x2 truck should stay within its 235/75R16 or 255/70R16 group, while a 4x4 should remain within its 245/75R16 or 265/75R16 group.
That approach keeps the truck visually grounded in the proportions GMC used for this generation rather than chasing a dramatically altered stance. If exact restoration details matter, compare the truck's current wheels and historical references for that configuration before deciding whether a wider or more aggressive-looking tire changes the overall presentation too much.
How does tire construction affect the appearance of a restored 2000 GMC Trucks Sierra 1500?
On the 2000 GMC Trucks Sierra 1500, construction is straightforward because the primary fitments are radial tires. That means the appearance question is less about bias-ply versus radial and more about the exact size, sidewall profile, and whether the tire uses a traditional raised white letter presentation.
A restored truck can look noticeably different if the tire becomes much wider, taller, or more aggressive in tread style than the size group intended for that sub-model. Staying with the correct 16-inch radial fitment and a sidewall style that suits the truck's era usually preserves a cleaner, more coherent finished look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2000 GMC Trucks Sierra 1500?
Yes. Modifications can change tire fitment on a 2000 GMC Trucks Sierra 1500 even when the truck still uses a 16-inch wheel. Aftermarket wheels, different wheel widths, suspension lifts, leveling kits, lowered ride height, and body or steering changes can all alter the clearance relationship around the tire.
That is especially important on a truck with multiple factory size paths between 4x2 and 4x4 models. Before replacing tires, check the actual size on the truck now, inspect for rubbing marks at full steering lock and suspension travel, and confirm that the wheel dimensions still suit the intended replacement size.
What should I inspect before driving a 2000 GMC Trucks Sierra 1500 on new tires?
Before road use, inspect the wheel condition, lug hardware, valve stems, and the tire's basic installed clearance on the 2000 GMC Trucks Sierra 1500. Tire pressure should be set correctly, and the tires should be checked for any visible mounting damage, uneven seating at the bead, or contact points near suspension and steering components.
A short local drive followed by a second inspection is a smart habit on a truck that may have seen wheel changes over the years. Watching for vibration, pull, unusual noise, or fresh rubbing marks helps catch fitment problems early before the truck is put back into regular highway or work duty.
How often should tires on a 2000 GMC Trucks Sierra 1500 be inspected?
Tires on a 2000 GMC Trucks Sierra 1500 should be inspected regularly, not just when tread looks worn. A monthly visual check is a sensible routine for pressure loss, cuts, bulges, cracking, uneven wear, and debris damage, especially on a truck that alternates between daily use, towing, and longer periods of sitting.
Inspection should also happen before any longer trip or heavier-duty use. Full-size pickups can hide developing issues until the truck is loaded or driven at speed, so keeping an eye on tread wear patterns and air retention can reveal alignment, suspension, or wheel-related concerns before they become larger problems.
