The 2009 Chevrolet Trucks Suburban 1500 sits in the long-running full-size SUV tradition, built for families, towing, cargo duty, and the kind of everyday road use that asks a lot from its tires. On a vehicle this large, tire fitment is tied closely to trim level and wheel package rather than a single one-size answer. This Suburban 1500 uses radial tire fitments in 265/70R17, 265/65R18, or 275/55R20 depending on sub-model. The main choice is confirming the correct wheel diameter first, then comparing the available tire style within the right size. That matters whether the goal is stock-style replacement, dependable road use, or matching an existing wheel setup.
Which Tire Size Is Right for The 2009 Chevrolet Trucks Suburban 1500
Three tire sizes apply to the 2009 Chevrolet Trucks Suburban 1500, and they vary by sub-model and wheel package rather than by tire construction. All are radial fitments, but they use different rim diameters: 17, 18, or 20 inches. The first step is identifying the exact Suburban 1500 trim and confirming the wheel diameter currently on the vehicle before comparing tire choices.
The 265/70R17 size uses a 265-millimeter section width, a 70-series aspect ratio, radial construction, and a 17-inch rim. On the 2009 Chevrolet Trucks Suburban 1500, it is one of the primary factory-style radial fitments and is used on specific sub-models with 17-inch wheels. Available options in this size include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls. This size is worth focusing on if the Suburban has 17-inch wheels and the goal is to keep the proper overall fitment while choosing between load and specification differences within the same size.
The 275/55R20 size indicates a 275-millimeter section width, a 55-series profile, radial construction, and fitment on a 20-inch rim. For the 2009 Chevrolet Trucks Suburban 1500, this size belongs to specific higher-wheel-package configurations rather than every sub-model. Its lower profile relative to the 17-inch and 18-inch fitments means the wheel diameter becomes the key confirmation point before selecting tires. This is the size to evaluate when the vehicle already carries 20-inch wheels and the owner wants to maintain the intended wheel-and-tire proportion for that setup.
The 265/65R18 size combines a 265-millimeter section width with a 65-series profile, radial construction, and an 18-inch rim. On the 2009 Chevrolet Trucks Suburban 1500, it applies to a specific sub-model configuration rather than the full range. It sits between the 17-inch and 20-inch fitments in wheel diameter while keeping a similar overall tire height, so wheel confirmation still matters more than appearance alone. This size should be considered when the Suburban is equipped with 18-inch wheels and the buyer wants to stay aligned with that trim-specific fitment.
2009 Chevrolet Trucks Suburban 1500 Sub-Model Tires
Sub-model fitment matters on the 2009 Chevrolet Trucks Suburban 1500 because tire size changes with trim and wheel package. Some versions share the same 17-inch fitment, while others move to 18-inch or 20-inch wheels, so identifying the exact sub-model is the safest starting point.

2009 Chevrolet Trucks Suburban 1500 LS
The 2009 Chevrolet Trucks Suburban 1500 LS uses a single radial tire fitment tied to its 17-inch wheel setup. Tire selection here is mostly about staying with the correct size and then comparing product details such as load specification and sidewall presentation within that fitment.
The 2009 Chevrolet Trucks Suburban 1500 LT can use either a 17-inch or 20-inch radial fitment depending on how the vehicle was equipped. Wheel diameter should be confirmed before shopping, since the decision is not just trim level but the actual wheel package currently on the Suburban.
The 2009 Chevrolet Trucks Suburban 1500 LT w/Z71 Pkg. uses its own radial tire fitment on an 18-inch wheel. That makes size confirmation straightforward, and the main task becomes matching the tire to the existing wheel setup and the vehicle's intended mix of road and utility use.
The 2009 Chevrolet Trucks Suburban 1500 LTZ uses the 20-inch radial fitment rather than the smaller wheel sizes found elsewhere in the range. Tire selection should center on retaining that wheel diameter and choosing a tire that matches the Suburban's current setup and use expectations.
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 2009 Chevrolet Trucks Suburban 1500?
A 2009 Chevrolet Trucks Suburban 1500 can use 265/70R17, 265/65R18, or 275/55R20 depending on sub-model and wheel package. The LS uses 265/70R17, the LT can use either 265/70R17 or 275/55R20, the LT w/Z71 Pkg. uses 265/65R18, and the LTZ uses 275/55R20.
The important next step is matching the tire size to the actual wheels on the vehicle, not just the model name on the badge. A used Suburban may have different wheels than it left the factory with, so checking the size on the current tire sidewall and confirming wheel diameter before ordering helps avoid an expensive mismatch.
What size rim does a 2009 Chevrolet Trucks Suburban 1500 use?
The 2009 Chevrolet Trucks Suburban 1500 uses 17-inch, 18-inch, or 20-inch rims depending on trim and wheel package. The 265/70R17 fitment uses a 17-inch rim, 265/65R18 uses an 18-inch rim, and 275/55R20 uses a 20-inch rim.
Rim diameter is the first fitment detail to verify because the three tire sizes are not interchangeable across those wheel diameters. Looking at the final number in the tire size makes this easy: 17, 18, or 20. Once that is confirmed, the buyer can compare the correct tire options for that wheel rather than sorting through sizes that cannot mount on the vehicle's current rims.
Why does the 2009 Chevrolet Trucks Suburban 1500 have more than one tire size?
The 2009 Chevrolet Trucks Suburban 1500 has more than one tire size because different sub-models and wheel packages use different wheel diameters. The range includes 17-inch, 18-inch, and 20-inch setups, so tire size follows the wheel package rather than remaining the same across every LS, LT, LT w/Z71 Pkg., and LTZ.
That means tire selection starts with configuration, not guesswork. An LT is the clearest example, since it can use either a 17-inch or 20-inch fitment. Checking the existing wheel and reading the tire sidewall are the quickest ways to narrow the choice. Once the actual setup is confirmed, the buying decision becomes much simpler and more accurate.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2009 Chevrolet Trucks Suburban 1500?
For a 2009 Chevrolet Trucks Suburban 1500 that uses 265/70R17, start with the correct wheel size and then compare the product's load specification, rim-width compatibility, and overall tire character. Available 265/70R17 choices include BFGoodrich All-Terrain T/A KO2 tires in radial construction with raised white letter sidewalls.
The two available 265/70R17 options differ in details such as maximum load capacity, pressure rating, and weight, even though they share the same size. That matters on a full-size SUV because cargo use, towing habits, and wheel specifications can influence which version makes more sense. Checking the existing wheel width and how the Suburban is used helps narrow the decision within the correct size.
What sidewall styles are available for 2009 Chevrolet Trucks Suburban 1500 tires?
Among the currently available products for the 2009 Chevrolet Trucks Suburban 1500, the visible sidewall style is RWL, or raised white letter, in 265/70R17. That gives the tire a more traditional truck-and-SUV appearance than a plain black sidewall while keeping the fitment in the correct radial size.
Sidewall style mostly affects presentation, but it can still influence the overall look of the Suburban, especially on a vehicle that blends utility with enthusiast appeal. Buyers trying to match an existing set should confirm what is already mounted on the truck. If appearance consistency matters, compare the sidewall treatment alongside load rating and wheel compatibility rather than treating style as the only selection factor.
What brands offer tires for the 2009 Chevrolet Trucks Suburban 1500?
Current product availability for the 2009 Chevrolet Trucks Suburban 1500 includes BFGoodrich in 265/70R17. The tire series represented is the All-Terrain T/A KO2, offered in radial construction with raised white letter sidewalls and more than one load specification within that size.
Brand is only one part of the choice on a large SUV like the Suburban. After confirming the correct tire size and wheel diameter, compare the exact version of the tire, including its maximum load capacity, pressure relationship, weight, and approved rim-width range. That approach keeps the focus on fitment and intended use rather than selecting by brand name alone.
Restoration & Appearance
Does correct tire fitment matter for a 2009 Chevrolet Trucks Suburban 1500 restoration?
Correct tire fitment matters on a 2009 Chevrolet Trucks Suburban 1500 restoration because wheel diameter and tire proportions are part of the vehicle's finished look. Using the right size for the trim or wheel package helps preserve the intended stance, especially since this Suburban can appear on 17-inch, 18-inch, or 20-inch wheel setups.
Appearance goals should be balanced with the actual equipment on the vehicle today. A restored LS, LT, Z71-equipped LT, or LTZ may no longer have its original wheels, so confirming the current setup is essential before buying tires. For buyers chasing a highly accurate presentation, trim-specific references and original vehicle documentation are useful alongside size confirmation.
Which tire should I choose for a period-style 2009 Chevrolet Trucks Suburban 1500?
A period-style 2009 Chevrolet Trucks Suburban 1500 should start with the correct size for its trim and wheel package: 265/70R17, 265/65R18, or 275/55R20. Because this is a modern full-size SUV from the late 2000s, the period-appropriate foundation is a radial tire that matches the proper wheel diameter and overall visual proportion.
From there, the right choice depends on the look being pursued. A raised white letter all-terrain tire can give a more assertive truck-style presentation on a 17-inch setup, while larger wheel packages carry a different visual balance. The safest way to keep the result convincing is to match the tire to the Suburban's actual wheel package rather than choosing by appearance alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Chevrolet Trucks Suburban 1500?
Yes, modifications can affect tire fitment on a 2009 Chevrolet Trucks Suburban 1500. Aftermarket wheels, changes in wheel width, suspension lifts or lowering, and body or fender alterations can change how a 265/70R17, 265/65R18, or 275/55R20 tire sits and clears during turning and suspension travel.
That is especially important on a Suburban because it is a large SUV that may have seen years of wheel-package changes. Measuring the existing wheel diameter and width, then checking tire clearance at full steering lock, is smarter than assuming a stock-size tire will always behave the same way. Any modified setup should be reviewed carefully before replacement tires are chosen.
What should I inspect before driving a 2009 Chevrolet Trucks Suburban 1500 on new tires?
Before driving a 2009 Chevrolet Trucks Suburban 1500 on new tires, inspect wheel condition, valve stems, lug hardware, and the basic suspension and steering components that influence tire wear and tracking. Tire pressure should be set correctly, and the installed size should match the vehicle's actual wheel diameter and intended position on the truck.
A close visual check after installation is just as important. Look for even bead seating, adequate clearance to suspension parts and fender liners, and any sign of rubbing while turning lock to lock. On a heavier SUV, a short test drive followed by a recheck for air loss, unusual vibration, or contact marks can catch small issues before they become larger ones.
What should I check before a longer drive in a 2009 Chevrolet Trucks Suburban 1500?
Before a longer drive in a 2009 Chevrolet Trucks Suburban 1500, confirm tire pressure, inspect the tread and sidewalls, and make sure all four tires match the intended size for the wheel setup on the vehicle. Also check for cuts, bulges, cracking, punctures, or uneven wear that may suggest an alignment or suspension issue.
Longer trips put more sustained heat and load into the tires, so small problems show up faster on a full-size SUV. It also helps to verify that the spare is usable and that the wheels are properly secured. A Suburban used for passengers, cargo, or towing should be checked more carefully than a short local-use vehicle, even when the tires look good at a glance.
