The 2006 Chevrolet Trucks Suburban 1500 sits in the long-running full-size SUV tradition that made the Suburban a go-to choice for families, towing, and heavy everyday use. By this point, the Suburban 1500 balanced truck-based durability with a more refined road-going role, so tire fitment can vary noticeably by trim and wheel package. This model uses radial tires, with primary sizes ranging from 245/75R16 and 265/70R16 to 265/70R17 and 275/55R20. That means the real choice is not just size, but whether the vehicle is set up for a more traditional all-terrain look or a larger-wheel appearance. Confirming the exact sub-model and wheel diameter should come before comparing tire options.
Which Tire Size Is Right for The 2006 Chevrolet Trucks Suburban 1500
Four primary tire sizes are used on the 2006 Chevrolet Trucks Suburban 1500, and they vary by sub-model and wheel package rather than by construction, since all of them are radial tires. The first step is confirming the exact sub-model and wheel diameter, because this Suburban can be equipped with 16-inch, 17-inch, or 20-inch rims. Once that is settled, the decision becomes selecting the right tire within that fitment and intended use.
245/75R16 is a metric radial size in which 245 identifies the nominal section width in millimeters, 75 is the aspect ratio, R marks radial construction, and 16 is the rim diameter in inches. On the 2006 Chevrolet Trucks Suburban 1500, this size is part of the 16-inch wheel fitment group and suits vehicles using that wheel setup. Available options in this size include BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. It is the right size to evaluate only after confirming that the Suburban is actually equipped with the corresponding 16-inch wheel package.
265/70R16 is a metric radial size with a 265-millimeter nominal section width, a 70-series profile, radial construction, and a 16-inch rim diameter. This size appears across several 2006 Chevrolet Trucks Suburban 1500 sub-models, making it one of the more common fitments within the range. BFGoodrich offers this size in the All-Terrain T/A KO2 series with raised white letter styling, giving it a more truck-oriented presentation. It is a useful fitment for owners who want to stay with the original wheel diameter while matching the Suburban's heavier-duty SUV character.
275/55R20 is a metric radial size where 275 is the nominal section width in millimeters, 55 is the aspect ratio, R denotes radial construction, and 20 is the wheel diameter. On the 2006 Chevrolet Trucks Suburban 1500, this fitment belongs to vehicles equipped with 20-inch wheels and appears on several upper trims and wheel-package combinations. The larger wheel diameter makes wheel confirmation especially important before tire selection. This size should be considered when the Suburban already has the proper 20-inch setup, not simply because another sub-model in the same year and model line used it.
265/70R17 is a metric radial size that combines a 265-millimeter nominal section width with a 70-series profile on a 17-inch rim. Within the 2006 Chevrolet Trucks Suburban 1500 range, this size is tied to the 17-inch wheel fitment and gives the buyer a distinct setup from the 16-inch and 20-inch options. BFGoodrich offers it in the All-Terrain T/A KO2 series with raised white letter sidewalls, and there are multiple load-capacity versions in this size. It is the fitment to review when the Suburban has the corresponding 17-inch wheel package and the owner wants an all-terrain-oriented tire choice.
2006 Chevrolet Trucks Suburban 1500 Sub-Model Tires
Tire fitment on the 2006 Chevrolet Trucks Suburban 1500 is not the same across every sub-model, so trim level and wheel package matter before choosing a tire. Several versions share sizes, but others move to different rim diameters, making sub-model confirmation the key first step.

2006 Chevrolet Trucks Suburban 1500 Base
The 2006 Chevrolet Trucks Suburban 1500 Base uses 16-inch tire fitments, with either 245/75R16 or 265/70R16 radial tires depending on the setup. Tire selection here starts with confirming which 16-inch wheel and size the vehicle actually carries, then comparing available options within that fitment.
The 2006 Chevrolet Trucks Suburban 1500 LS can use either 265/70R16 or 275/55R20, so the correct choice depends on whether it has 16-inch or 20-inch wheels. That makes wheel diameter the most important check before comparing tire style, load specification, or overall tire character.
The 2006 Chevrolet Trucks Suburban 1500 LT also spans two distinct fitments, using either 265/70R16 or 275/55R20 radial tires. Owners should confirm the actual wheel package on the vehicle first, since the larger 20-inch setup calls for a different tire size rather than a simple variation within the same rim diameter.
The 2006 Chevrolet Trucks Suburban 1500 LTZ uses the 275/55R20 radial fitment. That keeps tire selection focused on the existing 20-inch wheel setup and makes it especially important to verify wheel condition, rim size, and clearance before moving to any replacement tire.
The 2006 Chevrolet Trucks Suburban 1500 Z71 can use either 265/70R17 or 275/55R20, depending on its wheel package. Choosing the correct tire means confirming whether the vehicle has the 17-inch or 20-inch setup first, then selecting the tire that matches the intended road and light off-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.

Owners usually need to sort out exact tire size, wheel diameter, trim-specific fitment, and how available all-terrain radial options compare. These answers focus on the real questions that come up before replacing tires on a 2006 Chevrolet Trucks Suburban 1500.
Tire Size & Fitment
What tire size fits a 2006 Chevrolet Trucks Suburban 1500?
The 2006 Chevrolet Trucks Suburban 1500 uses four primary tire sizes: 245/75R16, 265/70R16, 265/70R17, and 275/55R20. All are radial sizes, and the correct one depends on the sub-model and wheel package rather than a single universal fitment across the whole Suburban 1500 range.
The practical step is to verify the exact sub-model and wheel diameter already on the vehicle before selecting a tire. A Base, LS, LT, LTZ, or Z71 Suburban 1500 may not use the same rim size, and a tire that matches one trim's setup is not automatically right for another.
What size rim does a 2006 Chevrolet Trucks Suburban 1500 use?
The 2006 Chevrolet Trucks Suburban 1500 can use 16-inch, 17-inch, or 20-inch rims, depending on the sub-model and wheel package. The tire sizes tied to those diameters are 245/75R16 and 265/70R16 on 16-inch rims, 265/70R17 on 17-inch rims, and 275/55R20 on 20-inch rims.
Rim diameter is the first thing to confirm because it determines the tire size family you can use. Checking the actual wheel on the vehicle matters even more on older SUVs, since aftermarket wheel changes are common and can make trim-based assumptions less reliable than a direct inspection.
Do all 2006 Chevrolet Trucks Suburban 1500 sub-models use the same tire size?
No, the 2006 Chevrolet Trucks Suburban 1500 sub-models do not all use the same tire size. Base models use 245/75R16 or 265/70R16, LS and LT models can use 265/70R16 or 275/55R20, LTZ uses 275/55R20, and Z71 can use 265/70R17 or 275/55R20.
That variation means sub-model identification is important, but it is not the only check. Two vehicles with the same trim name may still have different wheel packages, so matching the tire size to the wheel already installed is the safest way to narrow the correct replacement choices.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 Chevrolet Trucks Suburban 1500?
Start with the correct size for the vehicle's actual wheel setup: 245/75R16, 265/70R16, 265/70R17, or 275/55R20. Since this Suburban 1500 uses radial tires, the next factors are rim compatibility, load-capacity needs, and whether the vehicle is being used more for highway driving, utility work, or a more truck-oriented all-terrain look.
It also helps to compare the tire's rim-width range and the load figure at its stated inflation pressure. A Suburban used for passengers, cargo, or towing places different demands on its tires, so matching the tire to the wheel and the vehicle's real use matters as much as matching the size code.
What sidewall styles are available for 2006 Chevrolet Trucks Suburban 1500 tires?
The available products in the covered Suburban 1500 fitments use RWL sidewalls, meaning raised white letters. That styling appears on the BFGoodrich All-Terrain T/A KO2 options offered in the supported 16-inch and 17-inch sizes and gives the SUV a more traditional truck and utility-oriented appearance.
Sidewall style affects appearance more than fitment, but it can strongly influence the overall look of the vehicle. Owners trying to preserve a clean stock-style presentation may evaluate that differently than owners who want a more rugged all-terrain visual, so sidewall treatment is worth considering alongside size and load rating.
What tire series are available for the 2006 Chevrolet Trucks Suburban 1500?
The available products for the covered sizes on the 2006 Chevrolet Trucks Suburban 1500 are in the BFGoodrich All-Terrain T/A KO2 series. That series appears in 245/75R16, 265/70R16, and 265/70R17 fitments, including multiple load-capacity versions in the 265/70R17 size.
Because the series is consistent, the bigger comparison points become size, rim-width specification, load capacity, and vehicle setup rather than choosing between very different tire families. The best way to narrow the choice is to confirm the Suburban's wheel diameter first, then match the tire version to how the SUV is actually used.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Chevrolet Trucks Suburban 1500?
A period-style choice for a 2006 Chevrolet Trucks Suburban 1500 starts with keeping the correct tire size and wheel diameter for the specific sub-model and wheel package. For the available products in the covered sizes, the BFGoodrich All-Terrain T/A KO2 gives a truck-oriented look that suits the Suburban's full-size SUV character.
Appearance should still follow fitment, not the other way around. A 16-inch, 17-inch, or 20-inch setup changes the stance and visual balance of the vehicle, so matching the tire to the wheel actually installed is essential before deciding whether the overall presentation should lean more toward utility, street use, or a larger-wheel look.
Which sidewall style suits a period-style 2006 Chevrolet Trucks Suburban 1500?
Raised white letter sidewalls are the available sidewall treatment in the covered Suburban 1500 tire options, and they suit the era well if the goal is a traditional truck and SUV appearance. On a 2006 Chevrolet Trucks Suburban 1500, that style can complement the vehicle's utility-focused character without looking out of place.
The final choice depends on the look the owner wants the vehicle to project. A Suburban with all-terrain tires and RWL sidewalls tends to read more rugged, while buyers pursuing a very specific original-era presentation may want to compare surviving examples, factory literature, or marque references before settling on appearance details.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Chevrolet Trucks Suburban 1500?
Yes, modifications can affect tire fitment on a 2006 Chevrolet Trucks Suburban 1500 even when the tire size is correct for a stock setup. Aftermarket wheels, changes in wheel width or offset, suspension lifts or lowering, and body or fender changes can all alter the clearance available around the tire.
That is especially important on a vehicle that already spans 16-inch, 17-inch, and 20-inch fitments across its model range. Any time the Suburban has been changed from its original wheel and suspension setup, checking steering clearance, fender clearance, and full-travel suspension clearance should happen before assuming the same size will still work properly.
What should I inspect before driving a 2006 Chevrolet Trucks Suburban 1500 on new tires?
Before road use, inspect wheel condition, verify lug hardware is correct, and confirm the new tires match the wheel diameter and approved rim-width range for that size. It is also smart to look over suspension and steering components, because worn parts can affect how a full-size SUV tracks and wears its tires.
A second check should include tire pressure, visible clearance at lock-to-lock steering, and any signs of rubbing once the vehicle is on the ground. On an older Suburban 1500, a short local test drive can reveal vibration, contact, or handling issues early, before the vehicle is taken on a longer trip.
How often should tires on a 2006 Chevrolet Trucks Suburban 1500 be inspected?
Tires on a 2006 Chevrolet Trucks Suburban 1500 should be inspected regularly, not only by mileage. A quick visual check before routine driving and a more careful inspection at service intervals is a sensible approach, especially on a heavier SUV that may see passenger loads, cargo, or occasional towing duty.
Focus on tread wear, uneven wear patterns, cracking, cuts, bulges, and signs of air loss. Vehicles that sit for longer periods still need tire checks, since age, storage conditions, and underinflation can damage a tire even when mileage is low, and those issues may not be obvious until the Suburban is back on the road.
