The 2020 Chevrolet Trucks Tahoe sits in the full-size SUV segment where towing, family use, fleet duty, and everyday road comfort all intersect. In this generation, Tahoe buyers could end up with very different wheel-and-tire packages depending on trim and intended use, so tire selection starts with identifying the exact setup on the vehicle. Primary fitments range from 17-inch to 22-inch radial sizes, including 265/65R18, 275/55R20, 285/45R22, 265/60R17, 255/70R17, and 265/70R17. That means the decision is less about vintage-style construction and more about matching the right metric radial size, wheel diameter, and tire character to the Tahoe’s specific sub-model and use.
Which Tire Size Is Right for The 2020 Chevrolet Trucks Tahoe
The 2020 Chevrolet Trucks Tahoe uses six primary tire sizes, and they are tied to specific sub-models and wheel packages rather than one universal fitment. Rim diameter varies across 17-inch, 18-inch, 20-inch, and 22-inch applications, so the first step is confirming the exact sub-model and wheel size currently on the vehicle before comparing tire choices.
265/65R18 is a metric radial size in which 265 is the section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2020 Chevrolet Trucks Tahoe, this size is one of the mainstream SUV fitments and belongs on an 18-inch wheel. It appears on LS, LT, and SSV applications, so it is not shared across the entire Tahoe lineup. This size is the right one to evaluate when the vehicle already carries the matching 18-inch wheel package.
275/55R20 is a metric radial size with a 275-millimeter nominal section width, a 55-series profile, and a 20-inch rim diameter. This fitment gives the 2020 Chevrolet Trucks Tahoe a larger wheel package than the 17-inch and 18-inch applications, so wheel confirmation matters before any tire purchase. It is used on LS, LT, and Premier configurations, which makes it common but still not universal across all Tahoes. Choose this size only when the vehicle is equipped with the corresponding 20-inch setup and the sub-model supports it.
285/45R22 is a metric radial size where 285 indicates nominal width in millimeters, 45 identifies the aspect ratio, and 22 marks the wheel diameter in inches. On the 2020 Chevrolet Trucks Tahoe, this is the largest wheel-and-tire package among the primary fitments and is used on selected LS, LT, and Premier configurations. Its lower-profile format makes it a distinct fitment choice rather than a casual substitute for smaller-wheel Tahoe sizes. This is the size to match when the vehicle already uses a 22-inch factory-style or equivalent wheel package.
265/60R17 is a metric radial size that combines a 265-millimeter nominal section width with a 60-series profile on a 17-inch rim. On the 2020 Chevrolet Trucks Tahoe, this size is tied to the PPV application, making it a configuration-specific fitment rather than a general Tahoe size. Its role in the lineup is different from the larger-diameter 18-inch, 20-inch, and 22-inch wheel packages used elsewhere. This is the size to confirm when working with a PPV Tahoe or a vehicle that still retains that exact 17-inch wheel setup.
255/70R17 is a metric radial size with a 255-millimeter nominal section width, a 70-series aspect ratio, and a 17-inch wheel diameter. On the 2020 Chevrolet Trucks Tahoe, it appears in the SSV range, where it serves a different role from the PPV’s 265/60R17 and the larger-wheel civilian Tahoe sizes. The taller-profile 17-inch format makes wheel diameter confirmation especially important before comparing alternatives. This is the size to evaluate when the vehicle is an SSV equipped with the corresponding 17-inch wheel package.
265/70R17 is a metric radial size that uses a 265-millimeter nominal section width, a 70-series profile, and a 17-inch rim. On the 2020 Chevrolet Trucks Tahoe, this size is used on SSV applications and has available BFGoodrich All-Terrain T/A KO2 choices with raised white letter sidewalls. Those products share the same All Terrain TA KO2 series but differ in load capacity, inflation-pressure pairing, weight, and supported rim-width range. This size is the one to review when the Tahoe uses the SSV 17-inch setup and a more truck-oriented tire presentation is part of the goal.
Tire fitment on the 2020 Chevrolet Trucks Tahoe varies meaningfully by sub-model and wheel package, so there is no single size that covers the entire lineup. Checking the exact trim matters because some versions share multiple optional sizes while PPV and SSV applications use their own distinct 17-inch fitments.

2020 Chevrolet Trucks Tahoe LS
The 2020 Chevrolet Trucks Tahoe LS uses multiple radial tire sizes depending on wheel package, including 18-inch, 20-inch, and 22-inch applications. Tire selection starts with confirming which wheel diameter is on the vehicle now, then comparing the correct metric radial size for that exact setup.
The 2020 Chevrolet Trucks Tahoe LT also spans several radial fitments across 18-inch, 20-inch, and 22-inch wheel configurations. That makes wheel confirmation more important than trim name alone when choosing a replacement tire for an LT.
The 2020 Chevrolet Trucks Tahoe PPV uses a single 17-inch radial fitment, which keeps size selection more straightforward than on trims with multiple wheel-package options. The main job here is verifying that the vehicle still carries the correct PPV wheel setup and has not been changed to another Tahoe size.
The 2020 Chevrolet Trucks Tahoe Premier uses radial tire fitments tied to larger wheel packages rather than the full spread seen elsewhere in the range. Choosing the right tire comes down to confirming whether the vehicle is on its 20-inch or 22-inch setup before comparing replacement options.
The 2020 Chevrolet Trucks Tahoe SSV has the widest variation among the 17-inch and 18-inch radial choices in this group. Because the SSV can use more than one size, the current wheel diameter and exact tire code on the vehicle should be checked before selecting a 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.
Best 2020 Chevrolet Trucks Tahoe Tires for Sale
Available product choices center on 265/70R17, with BFGoodrich All-Terrain T/A KO2 options in raised white letter form. Within that size, the main comparison points are load-capacity and pressure pairing, weight, and the shared 17-inch rim-width range.
Tahoe owners usually need to sort out exact tire size by sub-model and wheel package before comparing brands, sidewall style, or heavier-duty tire specs. These FAQs focus on fitment, product selection, and the checks that matter before road use.
Tire Size & Fitment
What tire size fits a 2020 Chevrolet Trucks Tahoe?
The 2020 Chevrolet Trucks Tahoe uses six primary radial tire sizes: 265/65R18, 275/55R20, 285/45R22, 265/60R17, 255/70R17, and 265/70R17. Those sizes do not apply across the entire model line equally, because different Tahoe sub-models and wheel packages use different fitments.
The practical first step is checking the exact sub-model and wheel diameter already on the vehicle. LS, LT, Premier, PPV, and SSV configurations do not all share the same setup, and 17-inch, 18-inch, 20-inch, and 22-inch wheels each require their matching tire size.
What size rim does a 2020 Chevrolet Trucks Tahoe use?
A 2020 Chevrolet Trucks Tahoe can use 17-inch, 18-inch, 20-inch, or 22-inch rims depending on sub-model and wheel package. Rim diameter is tied directly to the tire size, so a 265/60R17 or 265/70R17 belongs on a 17-inch wheel, while 265/65R18, 275/55R20, and 285/45R22 require their corresponding diameters.
Because this Tahoe has multiple factory-style wheel diameters, measuring or reading the current wheel and tire markings is more useful than assuming by trim name alone. A replacement tire must match the actual rim diameter on the vehicle before width, profile, or product differences are considered.
Do all 2020 Chevrolet Trucks Tahoe sub-models use the same tire size?
No, 2020 Chevrolet Trucks Tahoe sub-models do not all use the same tire size. LS and LT can use 265/65R18, 275/55R20, or 285/45R22, Premier uses 275/55R20 or 285/45R22, PPV uses 265/60R17, and SSV uses 255/70R17, 265/65R18, or 265/70R17.
That variation means the safest path is to identify the exact sub-model and confirm the wheel package currently installed. This matters even more on vehicles that may have been changed from their original service or trim configuration, since the correct tire size follows the wheel and application together.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2020 Chevrolet Trucks Tahoe?
For a 2020 Chevrolet Trucks Tahoe using 265/70R17, start with the correct SSV application and a true 17-inch wheel. Then compare the available product details that actually vary within the size, such as load-capacity and pressure pairing, tire weight, and supported rim-width range.
In this size, the available BFGoodrich All-Terrain T/A KO2 choices share the same series and raised white letter sidewall style, but they are not identical in specification. Matching the tire to the Tahoe’s intended use, wheel width, and load needs is more important than choosing by size code alone.
What sidewall styles are available for 2020 Chevrolet Trucks Tahoe tires?
Among the currently available Tahoe products in 265/70R17, the sidewall style is RWL, or raised white letter. That gives the tire a more truck-oriented appearance than a plain blackwall presentation and suits buyers who want a more visibly rugged look on an SSV-style setup.
Sidewall style should still come after the basics of correct size, wheel diameter, and wheel-width compatibility. On a Tahoe, appearance matters, but the tire still needs to match the exact 17-inch application and the vehicle’s intended use before sidewall treatment becomes the deciding factor.
What brands offer tires for the 2020 Chevrolet Trucks Tahoe?
For the available 265/70R17 Tahoe products, the brand is BFGoodrich. The options in that size use the All-Terrain T/A KO2 series, so the main differences are not brand-to-brand but product specification differences within the same family of tire.
That means the comparison is less about choosing among several manufacturers and more about selecting the version that matches the Tahoe’s wheel-width range, load requirements, and use. Buyers focused on the SSV 17-inch setup should read the specification details closely rather than assuming every 265/70R17 is the same.
Restoration & Appearance
How does tire construction affect the appearance of a restored 2020 Chevrolet Trucks Tahoe?
On a 2020 Chevrolet Trucks Tahoe, tire construction is straightforward because the primary fitments are radial. The visual difference comes less from choosing bias-ply versus radial and more from selecting the correct modern metric size, wheel diameter, and sidewall presentation for the trim and overall vehicle character.
Appearance still matters on newer collector-oriented SUVs, especially when wheel packages vary from 17 to 22 inches. A Tahoe kept close to its original look should stay with the proper size and proportion for its exact setup, since the wrong profile or wheel diameter can change the stance noticeably.
Does correct tire fitment matter for a 2020 Chevrolet Trucks Tahoe restoration?
Yes, correct tire fitment matters on a 2020 Chevrolet Trucks Tahoe restoration or preservation project because the vehicle used several distinct wheel-and-tire combinations. Using the right size helps maintain the intended stance, wheel relationship, and overall presentation of the specific LS, LT, Premier, PPV, or SSV configuration.
Exact originality questions should be checked against the vehicle’s own build information and marque-specific references, especially if wheel packages may have changed over time. Even on a modern SUV, the correct diameter and profile make a visible difference before any brand or sidewall preference enters the discussion.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Chevrolet Trucks Tahoe?
Yes, modifications can affect tire fitment on a 2020 Chevrolet Trucks Tahoe. Wheel changes, altered offsets, suspension lifts or lowering, and body or fender changes can all influence whether the original Tahoe tire size remains the right choice for steering clearance, suspension travel, and overall package compatibility.
A Tahoe that still uses its original-style wheel package is easier to match correctly by size code alone. Once changes have been made, the actual wheel diameter and width should be confirmed and the tire checked for clearance at full steering lock and through normal suspension movement.
What should I inspect before driving a 2020 Chevrolet Trucks Tahoe on new tires?
Before driving a 2020 Chevrolet Trucks Tahoe on new tires, inspect the wheel condition, confirm the tire size matches the vehicle’s actual wheel diameter, and make sure inflation is set correctly for the tire in use. It also helps to check for rubbing, uneven ride height, or any visible clearance issue right away.
A short initial drive should be followed by another look at sidewall clearance, tread wear pattern, and air retention. On a Tahoe with multiple possible wheel packages, that first inspection is especially important because a correct-looking tire can still be wrong if the wheel setup was misidentified.
How should 265/70R17 tires on a collector 2020 Chevrolet Trucks Tahoe be maintained?
265/70R17 tires on a collector 2020 Chevrolet Trucks Tahoe should be kept at appropriate inflation for their application, inspected regularly for cracking, cuts, bulges, and irregular wear, and monitored for air loss during storage. Even low-mileage vehicles need tire checks because age and storage conditions can matter as much as tread depth.
Storage habits also affect tire life on an infrequently driven Tahoe. Keeping the vehicle away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires, and occasional movement prevents long-term flat spotting from becoming a road-use annoyance.
