The 2010 Chevrolet Trucks Avalanche sits at the intersection of full-size pickup utility and SUV comfort, with the distinctive midgate layout that made this generation especially versatile. Buyers often keep these trucks in service for towing, daily driving, and light off-road use, so tire selection has a direct effect on both stance and capability. For this model year, primary fitment centers on radial tires in 265/70R17 or 275/55R20, depending on wheel setup and sub-model. That means the real decision is not just size, but also confirming rim diameter and choosing the right overall tire character for how the truck is used.
Which Tire Size Is Right for The 2010 Chevrolet Trucks Avalanche
The 2010 Chevrolet Trucks Avalanche uses two primary tire sizes, and the first step is confirming which wheel diameter is on the truck. Both sizes are radial fitments, but one uses a 17-inch rim and the other uses a 20-inch rim, so selecting the correct tire starts with matching the actual wheel setup and then narrowing the choice by sub-model and intended use.
265/70R17 is a metric radial size in which 265 represents nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 17 is the rim diameter in inches. On the 2010 Chevrolet Trucks Avalanche, this size suits trucks equipped with 17-inch wheels and keeps the selection focused on a modern radial layout. Available choices in this size include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls. This size makes sense for owners who want to stay with the 17-inch wheel fitment and compare load range, tire weight, and all-terrain character within that setup.
275/55R20 is a metric radial size where 275 is the nominal width in millimeters, 55 is the aspect ratio, R denotes radial construction, and 20 indicates the wheel diameter in inches. For the 2010 Chevrolet Trucks Avalanche, this size applies to trucks running the 20-inch wheel package rather than the 17-inch setup. Its role is tied directly to that larger rim diameter, so it should be evaluated as a separate fitment path rather than an interchangeable alternative to the 17-inch size. Choosing it starts with confirming the truck's actual wheels and then checking clearance and overall setup if any modifications have been made.
Sub-model fitment on the 2010 Chevrolet Trucks Avalanche depends partly on wheel package rather than trim name alone. LS and LT can use either primary size, while LTZ centers on the 20-inch fitment, so confirming the exact sub-model and actual wheels matters before selecting a tire.

2010 Chevrolet Trucks Avalanche LS
The 2010 Chevrolet Trucks Avalanche LS can use either of the two radial tire sizes, depending on whether the truck has 17-inch or 20-inch wheels. Tire selection starts with matching the wheel diameter, then comparing the available tire style and intended use within that fitment.
The 2010 Chevrolet Trucks Avalanche LT also appears with both primary radial sizes, which makes wheel confirmation more important than trim badge alone. Once the wheel diameter is verified, the next step is choosing a tire that matches how the truck is driven and whether a more all-terrain presentation is desired.
The 2010 Chevrolet Trucks Avalanche LTZ uses the 275/55R20 radial fitment, tying this sub-model to a 20-inch wheel setup. That keeps the size decision straightforward, but the owner should still confirm the actual wheels on the truck if it has been changed from its original configuration.
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 2010 Chevrolet Trucks Avalanche Tires for Sale

These FAQs focus on the exact tire sizes used on the 2010 Chevrolet Trucks Avalanche, along with wheel-diameter differences, sub-model fitment, product choice, and practical checks to make before putting the truck back on the road.
Tire Size & Fitment
What tire size fits a 2010 Chevrolet Trucks Avalanche?
The 2010 Chevrolet Trucks Avalanche uses two primary tire sizes: 265/70R17 and 275/55R20. Both are radial tire fitments, and the correct one depends on the wheel package and sub-model. LS and LT can appear with either size, while LTZ uses 275/55R20.
The key step is matching the tire to the wheel diameter already on the truck. A 17-inch tire does not belong on a 20-inch wheel, and the reverse is also true. If the Avalanche has aftermarket wheels or has changed hands several times, checking the tire sidewall and measuring the wheel before ordering is the safest approach.
What size rim does a 2010 Chevrolet Trucks Avalanche use?
A 2010 Chevrolet Trucks Avalanche uses either a 17-inch or 20-inch rim, depending on which primary tire size is on the truck. The 265/70R17 fitment uses a 17-inch rim, and the 275/55R20 fitment uses a 20-inch rim.
That makes rim diameter the first fitment checkpoint before comparing tires. Once the wheel diameter is confirmed, the next consideration is whether the current wheel width suits the tire being considered. Trucks that have been modified with different wheels, offsets, or suspension changes should also be checked for clearance before switching to a new tire.
Do all 2010 Chevrolet Trucks Avalanche sub-models use the same tire size?
No, not every 2010 Chevrolet Trucks Avalanche sub-model uses the same tire size. LS and LT can use either 265/70R17 or 275/55R20, while LTZ uses 275/55R20. That means trim level helps narrow the choice, but wheel setup still matters.
The practical takeaway is that the badge on the truck is only part of the answer. An LS or LT may have either wheel diameter, so the actual wheel on the vehicle needs to be confirmed before selecting a tire. This is especially important on used trucks, where wheels and tires are commonly changed from original-style configurations.
Choosing the Right Tire
What should I consider when choosing a tire for a 2010 Chevrolet Trucks Avalanche?
Start with the correct primary size for the truck's actual wheels: 265/70R17 for a 17-inch setup or 275/55R20 for a 20-inch setup. From there, consider construction, intended use, and product details such as load capacity, inflation rating, rim-width compatibility, and tire weight.
An Avalanche used for daily driving, hauling, or rougher surfaces may call for a different tire character than one driven mostly on pavement. Matching the tire to how the truck is actually used is just as important as choosing the correct size. Owners should also account for any suspension changes, wheel swaps, or added vehicle weight before making a final decision.
What sidewall styles are available for 2010 Chevrolet Trucks Avalanche tires?
The currently available 265/70R17 product selection for the 2010 Chevrolet Trucks Avalanche includes RWL, or raised white letter, sidewall styling. That gives the truck a more traditional light-truck appearance than a plain black sidewall and can matter just as much as tread pattern for owners who care about presentation.
Sidewall style should still be treated as a secondary decision after confirming the correct size and wheel diameter. It helps shape the truck's visual character, but it does not override fitment, load needs, or wheel compatibility. On a truck that mixes utility use with enthusiast ownership, appearance and functional requirements should be balanced rather than treated separately.
What brands offer tires for the 2010 Chevrolet Trucks Avalanche?
Current product coverage for the 2010 Chevrolet Trucks Avalanche includes BFGoodrich in 265/70R17, specifically within the All-Terrain T/A KO2 line. That keeps the brand choice focused, but there is still meaningful variation within the available options because load capacity and tire weight are not the same across every version.
Brand matters, but it should be considered alongside the actual specification of the tire being chosen. Two tires from the same brand and series can still differ in load rating and inflation requirement, which can influence how appropriate they are for the truck's use. Matching the product to the vehicle setup remains more important than choosing by name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Chevrolet Trucks Avalanche?
A period-style 2010 Chevrolet Trucks Avalanche starts with keeping the truck in the correct primary size for its wheel setup, either 265/70R17 or 275/55R20. Since this model year uses radial tires, the appearance decision is more about wheel-and-tire presentation than about choosing between vintage bias-ply and radial construction.
Owners aiming for an early-2010s light-truck look should pay attention to wheel diameter, sidewall profile, and whether a more rugged all-terrain presentation suits the truck. That approach keeps the overall look coherent without forcing a claim of exact factory originality. For exact restoration-level accuracy, vehicle-specific documentation and original sales literature are still the best references.
Does correct tire fitment matter for a 2010 Chevrolet Trucks Avalanche restoration?
Yes, correct tire fitment matters because the 2010 Chevrolet Trucks Avalanche used more than one primary size, and each one is tied to a specific wheel diameter. Staying with the proper size preserves the truck's proportions and avoids the mismatched look that can come from using a tire intended for a different wheel package.
Appearance is only part of the story. Correct fitment also helps keep steering clearance, wheel compatibility, and overall stance within a sensible range for the truck. Even on a modern collectible or preservation-minded Avalanche, tire selection should support both the visual goal and the mechanical realities of the wheel and suspension setup already on the vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Chevrolet Trucks Avalanche?
Yes, modifications can affect tire fitment on a 2010 Chevrolet Trucks Avalanche even when the tire size itself looks close to stock. Wheel changes, altered offsets, suspension lifts or drops, and body modifications can all influence how a 265/70R17 or 275/55R20 tire sits within the wheel opening.
A truck with aftermarket wheels should be checked for inner clearance, fender clearance, and steering travel before a new tire is selected. Small fitment changes can become more noticeable under load or at full lock. Verifying the actual wheel dimensions and the truck's present ride height helps avoid choosing a tire that works on paper but crowds the chassis in use.
What should I inspect before driving a 2010 Chevrolet Trucks Avalanche on new tires?
Before driving a 2010 Chevrolet Trucks Avalanche on new tires, inspect wheel condition, lug hardware, valve stems, and inflation pressure, then confirm that all four tires match the intended size and construction. It is also smart to look over suspension and steering components so the new tires are not being asked to mask an existing chassis problem.
A short initial drive should include attention to rubbing, vibration, pulling, and any sign that the truck is not tracking normally. Rechecking pressure after the first miles is worthwhile, especially on a truck used for hauling or towing. Uneven wear patterns or steering issues that show up early usually point to alignment, wheel, or suspension concerns rather than the tire alone.
How often should tires on a 2010 Chevrolet Trucks Avalanche be inspected?
Tires on a 2010 Chevrolet Trucks Avalanche should be inspected regularly, with pressure and visible condition checked often enough that slow air loss, cuts, bulges, or uneven wear do not go unnoticed. A truck that sees mixed use, towing, or rougher surfaces benefits from more frequent attention than one driven lightly on pavement.
Inspection should cover tread depth, shoulder wear, sidewall condition, and signs of rubbing that may suggest wheel or suspension issues. Age also matters, especially on a low-mile truck that looks fine at a glance but spends long periods parked. Consistent checks help catch problems early and make it easier to get full service life from the correct tire size.
