The 2007 Chevrolet Trucks Avalanche sits in the era when full-size sport utility trucks were expected to handle daily driving, cargo duty, and weekend use with equal ease. Its midgate design and Silverado-based platform gave it a distinct role among GM trucks, which makes tire selection more about the exact trim and wheel package than broad one-size-fits-all advice. This Avalanche uses radial tires, with 265/70R17, 265/65R18, and 275/55R20 fitments depending on sub-model. That means the real choice centers on confirming trim and rim diameter first, then comparing available tire options and load characteristics. For owners keeping an Avalanche road-ready, wheel setup, intended use, and overall tire condition all matter before replacement.
Which Tire Size Is Right for The 2007 Chevrolet Trucks Avalanche
Three tire sizes apply to the 2007 Chevrolet Trucks Avalanche, and the correct one depends on the exact sub-model and wheel package. All three are radial fitments, but they use different rim diameters, so the first step is confirming whether the truck has 17-inch, 18-inch, or 20-inch wheels before comparing tire choices.
In 265/70R17, the 265 identifies nominal section width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. On the 2007 Chevrolet Trucks Avalanche, this is one of the primary truck-oriented fitments and is used on 17-inch wheels. Available choices in this size include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls and differing load specifications. This size is worth close attention if the truck retains its 17-inch wheel setup and is expected to balance everyday driving with light truck or utility use.
In 275/55R20, the 275 is the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 20 identifies a 20-inch rim. This size belongs to specific 2007 Chevrolet Trucks Avalanche configurations equipped with 20-inch wheels rather than the smaller 17-inch or 18-inch packages. Its lower-profile metric format gives the buyer a different fitment path than the other Avalanche sizes, so wheel diameter confirmation is especially important here. Choose this size only after verifying that the truck actually carries the correct 20-inch wheel package and has the necessary clearance for its existing setup.
In 265/65R18, the 265 is the nominal section width in millimeters, 65 is the aspect ratio, R means radial construction, and 18 is the wheel diameter in inches. This size is tied to the 18-inch wheel fitment used on the 2007 Chevrolet Trucks Avalanche LT w/Z71 Pkg., making it a distinct sub-model-specific choice rather than a universal Avalanche size. Its dimensions place it very close in overall diameter to the other Avalanche fitments, but the wheel diameter is different and must match the truck. This is the size to evaluate when the truck keeps its 18-inch wheels and the goal is preserving the intended Z71 wheel-and-tire setup.
Tire fitment varies across the 2007 Chevrolet Trucks Avalanche lineup, so identifying the exact sub-model is the key first step. Some trims share a 17-inch setup, while others move to 18-inch or 20-inch wheels that require a different tire size.

2007 Chevrolet Trucks Avalanche LS
The 2007 Chevrolet Trucks Avalanche LS uses the 265/70R17 radial size on a 17-inch wheel setup. Tire selection here is more straightforward, with the focus shifting from fitment identification to choosing the right load specification and overall tire character for how the truck is driven.
The 2007 Chevrolet Trucks Avalanche LT can use either 265/70R17 or 275/55R20, depending on the wheel package on the truck. That makes wheel diameter confirmation essential before replacement, since the LT does not rely on one single tire size across all configurations.
The 2007 Chevrolet Trucks Avalanche LT w/Z71 Pkg. uses the 265/65R18 radial size. For this sub-model, the main consideration is keeping the correct 18-inch wheel-and-tire pairing in place before comparing replacement tires or evaluating any change from the current setup.
The 2007 Chevrolet Trucks Avalanche LTZ uses the 275/55R20 radial size on a 20-inch wheel package. That makes the selection process less about multiple size possibilities and more about confirming the existing wheels, overall condition, and intended use before replacement.
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 of a 2007 Chevrolet Trucks Avalanche usually need to sort out trim-specific tire size, wheel diameter, and practical replacement choices first. These FAQs focus on fitment, product selection, modifications, and the checks that matter before putting the truck back on the road.
Tire Size & Fitment
What tire size fits a 2007 Chevrolet Trucks Avalanche?
The 2007 Chevrolet Trucks Avalanche uses three possible tire sizes: 265/70R17, 265/65R18, and 275/55R20. The correct size depends on the specific sub-model and wheel package, with LS using 265/70R17, LT using either 265/70R17 or 275/55R20, LT w/Z71 Pkg. using 265/65R18, and LTZ using 275/55R20.
That makes trim and wheel confirmation more important than assuming every Avalanche uses the same tire. Checking the truck’s current wheel diameter and comparing it to the actual sub-model setup helps avoid ordering a tire that matches the truck generally but not the wheels currently on it.
What size rim does a 2007 Chevrolet Trucks Avalanche use?
A 2007 Chevrolet Trucks Avalanche can use 17-inch, 18-inch, or 20-inch rims, depending on sub-model. The 265/70R17 tire fits a 17-inch rim, the 265/65R18 fits an 18-inch rim, and the 275/55R20 fits a 20-inch rim.
Rim diameter is the first fitment check because none of these tire sizes cross over onto a different wheel diameter. Looking at the existing wheel, the tire sidewall, and the exact trim level is the simplest way to confirm whether the truck needs a 17-, 18-, or 20-inch replacement tire.
Do all 2007 Chevrolet Trucks Avalanche sub-models use the same tire size?
No, the 2007 Chevrolet Trucks Avalanche does not use one tire size across all sub-models. LS uses 265/70R17, LT can use 265/70R17 or 275/55R20, LT w/Z71 Pkg. uses 265/65R18, and LTZ uses 275/55R20.
That variation usually reflects the wheel package rather than a simple year-and-model rule. Anyone replacing tires should verify the exact sub-model and the wheels actually on the truck, especially if it is an LT, since that trim can appear with either a 17-inch or 20-inch fitment.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2007 Chevrolet Trucks Avalanche?
Start with the correct size, then compare load specification, intended use, and wheel compatibility. For the 2007 Chevrolet Trucks Avalanche, available 265/70R17 choices include BFGoodrich All-Terrain T/A KO2 tires in the same basic size but with different load capacities, inflation figures, and product weights.
A truck used for lighter everyday driving may lead the buyer in a different direction than one expected to carry more weight or see rougher service. It also helps to confirm that the wheel falls within the stated 7.0- to 9.0-inch rim-width range before choosing between products in this size.
What sidewall styles are available for 2007 Chevrolet Trucks Avalanche tires?
Among the currently available 265/70R17 options for the 2007 Chevrolet Trucks Avalanche, the sidewall style is RWL, or raised white letter. That gives the truck a more traditional light-truck appearance than a plain black sidewall and can play a role in the overall look as much as in specification matching.
Sidewall choice matters most when appearance is part of the decision, especially on a truck that mixes utility use with enthusiast ownership. Buyers should still treat sidewall style as a finishing detail after the basics are confirmed, including the correct size, load rating, and wheel compatibility.
What brands offer tires for the 2007 Chevrolet Trucks Avalanche?
Current product availability for the 2007 Chevrolet Trucks Avalanche includes BFGoodrich in the 265/70R17 size. The available tires in that fitment are part of the All-Terrain T/A KO2 line and give buyers a recognizable truck-oriented option within the proper 17-inch radial size.
Brand is only one part of the decision, since the truck may use more than one size across the model range and even the same size can carry different load specifications. Matching the tire to the exact wheel package and the truck’s real use matters more than choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Chevrolet Trucks Avalanche?
A period-style choice for a 2007 Chevrolet Trucks Avalanche starts with keeping the tire size and wheel diameter that belong to the truck’s actual sub-model. For an LS, that means 265/70R17, while LT w/Z71 Pkg. uses 265/65R18 and LTZ uses 275/55R20.
Appearance usually looks most natural when the truck keeps the same overall wheel-and-tire proportion it was built around. On a vehicle from this era, preserving the original-style stance often matters more visually than chasing a different size that may alter the look or require additional clearance checks.
Which sidewall style suits a period-style 2007 Chevrolet Trucks Avalanche?
Raised white letter sidewalls are available in the 265/70R17 fitment for the 2007 Chevrolet Trucks Avalanche, and that style suits the late-2000s truck and SUV look naturally. It gives the tire a more purposeful light-truck presentation than a plain blackwall and can complement the Avalanche’s body and wheel design.
The better choice still depends on the truck’s overall presentation and the exact wheel package in use. Owners aiming for a stock-style appearance should compare the existing tire look, wheel finish, and trim level so the replacement tire matches the truck’s character rather than standing out awkwardly.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Chevrolet Trucks Avalanche?
Yes, modifications can affect tire fitment on a 2007 Chevrolet Trucks Avalanche even when the tire size is correct for a stock sub-model. Aftermarket wheels, changes in wheel width, suspension lifts or lowering, and body or fender alterations can all change the space available for the tire.
An Avalanche with non-original wheels or suspension should be checked more carefully before replacement. Verifying rim diameter, wheel width, and clearance at full steering lock helps prevent rubbing or mismatch, especially on LT models where more than one original wheel-and-tire package was used.
What should I inspect before driving a 2007 Chevrolet Trucks Avalanche on new tires?
Before driving a 2007 Chevrolet Trucks Avalanche on new tires, inspect the wheels for damage, confirm proper inflation, and make sure the new tires match the truck’s actual wheel diameter and intended sub-model fitment. It is also smart to look over the suspension and steering components for obvious wear.
A fresh set of tires performs best when the rest of the setup is sound. Alignment condition, uneven wear on the old tires, and any signs of rubbing or contact inside the wheel wells are worth checking early so the replacement tires start out with the best chance of wearing evenly.
What should I check before a longer drive in a 2007 Chevrolet Trucks Avalanche?
Before a longer drive, check tire pressure, tread condition, visible cuts or bulges, and any signs of slow air loss on the 2007 Chevrolet Trucks Avalanche. The truck should also be wearing the correct size for its wheel package, whether that is 265/70R17, 265/65R18, or 275/55R20.
Longer trips put more heat and sustained load into the tires, so basic condition matters as much as fitment. It also helps to inspect for uneven wear that may point to alignment or suspension issues, since catching that before the trip is easier than dealing with accelerated wear on the road.
