The 2018 Chevrolet Trucks Tahoe sits in the modern full-size SUV class where family hauling, towing, fleet duty, and long-wheelbase road comfort all meet. By this point, the Tahoe had evolved into a highly versatile platform, so tire fitment is tied closely to trim level and intended use rather than a single across-the-board size. Depending on sub-model, the 2018 Chevrolet Trucks Tahoe uses radial tire sizes ranging from 17-inch applications up to 22-inch fitments. That makes the real decision less about bias-ply versus radial and more about confirming the exact wheel setup, then matching the right profile, load capability, and overall look for everyday driving or utility-focused use.
Which Tire Size Is Right for The 2018 Chevrolet Trucks Tahoe
The 2018 Chevrolet Trucks Tahoe uses six primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All of these fitments are radial, but they span 17-inch, 18-inch, 20-inch, and 22-inch rims, so the first step is confirming the Tahoe's actual wheel setup before comparing tread style, load specification, or product details.
265/65R18 is a metric radial size in which 265 identifies the nominal section width in millimeters, 65 is the aspect ratio, R designates radial construction, and 18 is the rim diameter in inches. On the 2018 Chevrolet Trucks Tahoe, this size belongs to wheel packages that use an 18-inch rim and reflects a modern SUV fitment rather than a vintage sizing system. It is a useful size to confirm carefully on LS, LT, and some SSV configurations, especially if the vehicle has changed wheels over time. Matching the size to the actual wheel remains more important than choosing by trim name alone.
275/55R20 is a metric radial size with a 275-millimeter nominal section width, a 55-series profile, radial construction, and a 20-inch rim requirement. For the 2018 Chevrolet Trucks Tahoe, this size appears on certain higher-wheel-diameter configurations and gives the vehicle a distinct fitment path from the 17-inch and 18-inch applications. It is relevant on LS, LT, and Premier models that carry 20-inch wheels. Buyers considering this size should verify the Tahoe's present wheel diameter first, since trim overlap means the same model line may appear with more than one factory-style wheel setup.
285/45R22 is a metric radial size where 285 is the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 22 is the wheel diameter in inches. On the 2018 Chevrolet Trucks Tahoe, this is the largest primary wheel-diameter fitment in the range and is tied to specific sub-model and wheel-package combinations. It appears on certain LS, LT, Premier, and RST applications. This size should be chosen only after confirming that the Tahoe is actually equipped with 22-inch wheels, since moving between wheel diameters is not simply a tire-selection decision.
265/60R17 is a metric radial size with a 265-millimeter nominal width, a 60-series profile, and a 17-inch rim diameter. Within the 2018 Chevrolet Trucks Tahoe lineup, this size is associated with the PPV configuration and stands apart from the other 17-inch sizes by combining the same nominal width as some larger-diameter options with a shorter sidewall. That makes exact sub-model confirmation especially important here. Anyone selecting this size should confirm both the PPV designation and the actual wheel setup before comparing other 17-inch Tahoe tires.
255/70R17 is a metric radial size in which 255 gives the nominal section width in millimeters, 70 is the aspect ratio, and 17 is the required rim diameter in inches. On the 2018 Chevrolet Trucks Tahoe, this size appears on certain SSV applications and shares the same wheel diameter as other Tahoe fitments while using a different width and profile combination. That makes it important not to assume every 17-inch Tahoe tire is interchangeable. This size is best evaluated by confirming the exact SSV setup and then checking the wheel specification already on the vehicle.
265/70R17 is a metric radial size with a 265-millimeter nominal section width, a 70-series profile, radial construction, and a 17-inch rim requirement. For the 2018 Chevrolet Trucks Tahoe, this size is used on certain SSV applications and is the one 17-inch fitment here with currently available BFGoodrich All-Terrain T/A KO2 options in raised white letter form. Those products differ in load specification, rim-width compatibility, and weight, which matters for utility-oriented or more rugged-use Tahoes. It is the right size to evaluate only after confirming that the vehicle's wheel and sub-model setup matches this particular 17-inch application.
Sub-model fitment matters on the 2018 Chevrolet Trucks Tahoe because tire size changes across the lineup and, in some cases, within the same trim family. Confirming the exact sub-model and wheel diameter is the clearest way to narrow the correct tire before comparing available product choices.

2018 Chevrolet Trucks Tahoe LS
The 2018 Chevrolet Trucks Tahoe LS uses more than one tire size, spanning 18-inch, 20-inch, and 22-inch wheel applications. Tire selection starts with confirming the actual wheel diameter on the vehicle, since the trim name alone does not point to one single Tahoe LS fitment.
The 2018 Chevrolet Trucks Tahoe LT also carries multiple tire-size paths, with fitments tied to 18-inch, 20-inch, and 22-inch wheels. That means the practical first step is checking the current wheel setup before comparing tire profile, appearance, or other product-specific details.
The 2018 Chevrolet Trucks Tahoe PPV uses one primary tire size, making its fitment more straightforward than several other Tahoe sub-models. Selection is centered on staying with the correct 17-inch radial size and verifying that the vehicle still retains its intended PPV wheel setup.
The 2018 Chevrolet Trucks Tahoe Premier uses either a 20-inch or 22-inch tire fitment depending on the wheel configuration. Buyers should confirm which wheel diameter is on the vehicle first, then compare tires within that exact size rather than treating all Premier models as identical.
The 2018 Chevrolet Trucks Tahoe RST uses a single 22-inch radial tire size, which simplifies size identification. The main decision then becomes choosing the right tire within that fitment and making sure the Tahoe still has its correct 22-inch wheel arrangement.
The 2018 Chevrolet Trucks Tahoe SSV has the widest spread of 17-inch and 18-inch size possibilities in this group. Exact tire selection depends on confirming the vehicle's current wheel diameter and matching the specific SSV setup before looking at tread style or load-related product differences.
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.

Tahoe tire questions usually come down to exact size by sub-model, wheel diameter, and choosing the right radial tire for the vehicle's intended use. The FAQs below focus on fitment, product selection, maintenance, and road-use checks for the 2018 Chevrolet Trucks Tahoe.
Tire Size & Fitment
What tire size fits a 2018 Chevrolet Trucks Tahoe?
The 2018 Chevrolet Trucks Tahoe uses several primary tire sizes: 265/65R18, 275/55R20, 285/45R22, 265/60R17, 255/70R17, and 265/70R17. All are radial sizes, but they do not apply across every Tahoe configuration, because fitment changes by sub-model and wheel package.
The practical step is to confirm the exact sub-model and then check the wheel diameter already on the vehicle. A Tahoe LS, LT, Premier, PPV, RST, or SSV may not share the same tire, and 17-inch, 18-inch, 20-inch, and 22-inch wheels each point to different size requirements.
What size rim does a 2018 Chevrolet Trucks Tahoe use?
A 2018 Chevrolet Trucks Tahoe may use 17-inch, 18-inch, 20-inch, or 22-inch rims depending on the sub-model and wheel setup. Those rim diameters correspond to the six primary tire sizes used on this Tahoe range, so wheel diameter is one of the first fitment details to verify.
The rim diameter should be matched to the tire size exactly, not estimated by appearance. Checking the stamping on the wheel, the sidewall on the current tire, and the sub-model together helps prevent ordering a tire for the wrong wheel package, especially on trims that were offered with more than one size.
Why does the 2018 Chevrolet Trucks Tahoe have more than one tire size?
The 2018 Chevrolet Trucks Tahoe has more than one tire size because the lineup includes several sub-models and multiple wheel packages. LS and LT can use 18-inch, 20-inch, or 22-inch fitments, Premier uses 20-inch or 22-inch sizes, and PPV, RST, and SSV each follow their own fitment paths.
That variation means trim name alone is not always enough to choose a tire. Wheel diameter, present equipment, and any later wheel changes all matter, so the safest approach is to confirm the actual tire size on the vehicle and match it to the correct Tahoe configuration before comparing brands or tread styles.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2018 Chevrolet Trucks Tahoe?
For a 2018 Chevrolet Trucks Tahoe using 265/70R17, the first priorities are confirming that this is the correct SSV fitment and matching the tire to the 17-inch wheel. Available options in this size include BFGoodrich All-Terrain T/A KO2 products with raised white letter sidewalls and different load specifications.
Selection becomes more specific once the size is confirmed. Compare rim-width range, maximum load at the stated pressure, tire weight, and the vehicle's intended use, especially if the Tahoe sees utility duty or rougher surfaces. A more aggressive tire choice should still be checked against wheel compatibility and clearance.
What sidewall styles are available for 2018 Chevrolet Trucks Tahoe tires?
Current product availability for the 2018 Chevrolet Trucks Tahoe includes raised white letter sidewalls in 265/70R17. That style appears on BFGoodrich All-Terrain T/A KO2 options and gives the tire a more traditional truck-oriented appearance than a plain black sidewall presentation.
Sidewall style is mostly an appearance choice unless it comes with a different tire line or specification. Once the correct size is confirmed, a raised white letter tire may appeal to buyers who want a more rugged visual character, but the fitment decision should still center on the Tahoe's wheel size and intended use.
What brands offer tires for the 2018 Chevrolet Trucks Tahoe?
Current product coverage for this 2018 Chevrolet Trucks Tahoe fitment includes BFGoodrich in 265/70R17. The available tires are from the All-Terrain T/A KO2 series, giving buyers an option aimed at truck and SUV use within that specific size.
Brand choice only matters after the right tire size has been confirmed for the exact Tahoe sub-model and wheel diameter. A buyer looking at 17-inch SSV fitment can then compare the BFGoodrich options by sidewall style, load specification, weight, and rim-width compatibility rather than choosing on brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Chevrolet Trucks Tahoe?
A period-style 2018 Chevrolet Trucks Tahoe starts with using the correct size for the exact sub-model and wheel package, since this SUV was offered with several modern radial fitments. On a utility-oriented SSV using 265/70R17, an all-terrain tire with raised white letters can reinforce a more truck-focused presentation.
Appearance should be matched to how the Tahoe is being preserved or presented. Some owners may want a cleaner stock-style look, while others may prefer a more assertive SUV or service-vehicle character, but the tire should still stay within the proper size and wheel-diameter range for the vehicle's setup.
How does tire construction affect the appearance of a restored 2018 Chevrolet Trucks Tahoe?
On the 2018 Chevrolet Trucks Tahoe, the primary fitments are already radial, so construction choice is less about vintage bias-ply versus radial appearance and more about the style of the radial tire itself. Sidewall treatment, tread character, and wheel diameter have a stronger visual effect than construction type here.
That means a restoration-oriented or collector-minded Tahoe owner should focus on getting the size and wheel package right first. After that, the appearance decision usually comes down to whether the vehicle should look more stock, more upscale, or more utility-focused, especially on 17-inch SSV applications with raised white letter choices.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Chevrolet Trucks Tahoe?
Yes, modifications can affect tire fitment on a 2018 Chevrolet Trucks Tahoe. Aftermarket wheels, changes in wheel width, suspension alterations, leveling or lowering, and body modifications can all change the space available around the tire even when the vehicle still appears to use a stock-style size.
A Tahoe that has been altered should be checked at the wheel, not just by trim designation. Steering clearance, fender clearance, and the actual wheel diameter all matter, especially because this model range already spans 17-inch through 22-inch fitments. Small setup changes can turn a correct size on paper into a poor match.
What should I inspect before driving a 2018 Chevrolet Trucks Tahoe on new tires?
Before driving a 2018 Chevrolet Trucks Tahoe on new tires, inspect wheel condition, valve stems, lug hardware, and the wheel's actual diameter and width. The tire itself should be checked for correct size, proper inflation, and even seating on the rim before the vehicle goes back into regular road use.
It also helps to look over suspension and steering components, especially on a heavier full-size SUV where worn parts can affect tire wear and handling. A short, careful test drive should include checking for rubbing, vibration, pulling, or unusual noise so any fitment issue is caught early.
How often should tires on a 2018 Chevrolet Trucks Tahoe be inspected?
Tires on a 2018 Chevrolet Trucks Tahoe should be inspected regularly, not just at replacement time. Pressure, tread wear, cuts, bulges, and sidewall cracking are worth checking often, and low-use vehicles still need attention because time and storage conditions can affect tire condition even when miles stay low.
A quick visual inspection before longer drives is especially useful on an SUV that may carry passengers, cargo, or towing loads. Uneven wear can also point to alignment, suspension, or inflation issues, so routine checks help protect both tire life and overall road manners in daily or occasional use.
