The 2020 Toyota Avalon sits at the full-size end of Toyota’s sedan lineup, blending everyday comfort with a more contemporary, low-slung design than earlier Avalons. Trim level matters on this generation because tire fitment changes with the car’s intended character, from efficiency-minded hybrid and XLE models to the more aggressive TRD, Touring, and XSE variants. This Avalon uses radial tires in three primary sizes: 215/55R17, 235/45R18, and 235/40R19. Available choices center on BFGoodrich performance-oriented radial lines with blackwall styling. The key step is matching the exact sub-model and wheel diameter before comparing tire series, load details, and overall road-use priorities.
Which Tire Size Is Right for The 2020 Toyota Avalon
The 2020 Toyota Avalon uses three different tire sizes, and the right one depends on the exact sub-model and its wheel diameter. All three are radial fitments, but they span 17-inch, 18-inch, and 19-inch rims, so confirming the car’s current wheel size is the first step before comparing tire series or selecting a replacement.
In 215/55R17, the 215 is the section width in millimeters, 55 is the aspect ratio, R means radial, and 17 identifies the rim diameter in inches. On the 2020 Toyota Avalon, this size belongs to sub-models using the smaller 17-inch wheel package rather than the larger 18-inch or 19-inch setups. BFGoodrich offers blackwall choices here in the g-Force Comp 2 AS and g-Force Phenom T/A lines. This size is the one to focus on for XLE and Hybrid XLE applications, where wheel diameter confirmation matters more than visual similarity to the other Avalon sizes.
In 235/40R19, the 235 denotes tire width in millimeters, 40 is the aspect ratio, R stands for radial construction, and 19 is the rim diameter in inches. This size is used on the 2020 Toyota Avalon trims equipped with the largest wheel package, giving those versions a distinctly different fitment path than 17-inch and 18-inch models. The available product choice in this size is a BFGoodrich g-Force Phenom T/A blackwall radial. It is the size to confirm for TRD, Touring, and XSE cars, particularly if wheel or suspension changes have altered the car from its original setup.
Tire fitment on the 2020 Toyota Avalon varies by sub-model, so selecting tires starts with identifying the exact trim and wheel package. Some versions share the same size, but the overall range spans 17-inch, 18-inch, and 19-inch fitments.

2020 Toyota Avalon Hybrid Limited
The 2020 Toyota Avalon Hybrid Limited uses an 18-inch radial tire fitment rather than the 17-inch setup found on some other hybrid trims. That makes wheel confirmation important before choosing among available blackwall BFGoodrich tire series in the matching size.
The 2020 Toyota Avalon Hybrid XLE uses the 17-inch radial fitment, separating it from Hybrid Limited and Hybrid XSE models. Tire selection here centers on staying with the correct wheel diameter and then comparing the available BFGoodrich blackwall options in that size.
The 2020 Toyota Avalon Hybrid XSE uses an 18-inch radial tire size shared with certain non-hybrid trims. The practical decision is less about construction and more about confirming the wheel package, then choosing the tire series that best fits the car’s intended road use.
The 2020 Toyota Avalon Limited uses the same 18-inch radial fitment found on several other trims. Replacement tire shopping should focus on the correct 18-inch size first, followed by comparison of the available BFGoodrich series and load-related specifications.
The 2020 Toyota Avalon TRD uses the 19-inch radial fitment, placing it with the larger-wheel Avalon configurations rather than the 17-inch or 18-inch versions. Tire choice depends on keeping that 19-inch setup in mind and checking wheel width and clearance if the car has been modified.
The 2020 Toyota Avalon Touring uses the same 19-inch radial tire size as other larger-wheel trims. For replacement purposes, the main step is matching that wheel diameter exactly and then reviewing the available product’s rim-width and load specifications.
The 2020 Toyota Avalon XLE uses the 17-inch radial fitment shared with the Hybrid XLE. That keeps tire selection straightforward as long as the original wheel size is still on the car and replacement choices stay within the correct 17-inch format.
The 2020 Toyota Avalon XSE uses the 19-inch radial setup rather than the 17-inch or 18-inch Avalon fitments. Choosing tires for this trim starts with confirming the existing 19-inch wheels, then matching the tire’s intended use to the available blackwall radial offering.
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 2020 Toyota Avalon?
The 2020 Toyota Avalon uses three primary tire sizes: 215/55R17, 235/45R18, and 235/40R19. The correct size depends on the exact sub-model, since XLE and Hybrid XLE use 17-inch fitment, several Limited and Hybrid trims use 18-inch fitment, and TRD, Touring, and XSE models use 19-inch fitment.
Choosing the right tire starts with matching the car’s trim and actual wheel diameter, not just the model name on the trunk. If the Avalon has aftermarket wheels or a previous owner changed the tire package, check the wheel size on the car before ordering a replacement.
What size rim does a 2020 Toyota Avalon use?
A 2020 Toyota Avalon can use 17-inch, 18-inch, or 19-inch rims, depending on the sub-model. The 215/55R17 tire mounts on a 17-inch wheel, 235/45R18 fits an 18-inch wheel, and 235/40R19 fits a 19-inch wheel.
Rim diameter is the first thing to confirm because a tire for one Avalon wheel size will not work on another. It also helps to verify wheel width, especially on cars with replacement wheels, since the available tire options in each size carry their own rim-width ranges.
Do all 2020 Toyota Avalon sub-models use the same tire size?
No, 2020 Toyota Avalon sub-models do not all use the same tire size. Fitment varies across the lineup, with 215/55R17, 235/45R18, and 235/40R19 all used depending on whether the car is an XLE, Limited, Hybrid variant, TRD, Touring, or XSE.
That variation means trim identification matters before comparing products. Two Avalons may look similar but still need different wheel diameters and tire sizes, so checking the sub-model and the tire placard or current wheel setup is the safest way to narrow the choices correctly.
Choosing the Right Tire
What should I consider when choosing a 2020 Toyota Avalon tire?
Start with the correct Avalon tire size for the car’s sub-model and wheel diameter, then compare the available radial options within that exact fitment. For this application, choices vary by tire series, rim-width specification, weight, and in some cases maximum load information.
A sensible next step is to match the tire to how the car is actually used. A stock daily-driven Avalon may simply need the right size and rim compatibility, while a modified or larger-wheel car deserves extra attention to wheel width, suspension clearance, and the intended balance of comfort and responsiveness.
What sidewall styles are available for 2020 Toyota Avalon tires?
The available tire choices for the 2020 Toyota Avalon use blackwall sidewalls. That gives the car a clean modern appearance consistent with the Avalon’s contemporary full-size sedan character rather than a vintage-style whitewall or raised-letter presentation.
Since sidewall appearance is straightforward here, the real comparison shifts to tire size, series, and wheel compatibility. Once the correct 17-inch, 18-inch, or 19-inch fitment is confirmed, the buyer can focus on product specifications instead of choosing between multiple sidewall treatments.
What tire series are available for the 2020 Toyota Avalon?
Available 2020 Toyota Avalon tire series include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, depending on size. The 18-inch fitment has the broadest series selection, while the 17-inch size has two series and the 19-inch size is represented by the g-Force Phenom T/A.
That spread means some Avalon trims offer more product comparison than others. Once the correct size is confirmed, it helps to review the series alongside rim-width range, load details where given, and the car’s intended use rather than assuming every series is available in every Avalon fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Toyota Avalon?
Yes, modifications can affect tire fitment on a 2020 Toyota Avalon, especially because the car already spans 17-inch, 18-inch, and 19-inch wheel packages from the factory. Aftermarket wheels, altered offsets, suspension changes, or lowering can all change the clearance relationship between the tire and the car.
Even when the replacement tire matches one of the original Avalon sizes, a modified setup should still be checked for steering clearance, fender space, and wheel-width suitability. That matters most on 19-inch applications, where less sidewall height leaves less room for assumptions about wheel and suspension changes.
What should I inspect before driving a 2020 Toyota Avalon on new tires?
Before driving a 2020 Toyota Avalon on new tires, inspect air pressure, wheel lug torque, visible bead seating, and basic clearance at full steering lock if applicable. It is also worth checking the old tires for uneven wear, since that can point to alignment or suspension issues that may affect the new set.
A short first drive should be used to confirm smooth tracking, no rubbing, and no vibration. Any pull, shake, or contact with the inner fender or suspension is a sign to recheck wheel fitment, balance, and alignment before putting more miles on the car.
What should I check before a longer drive in a 2020 Toyota Avalon?
Before a longer drive, check the 2020 Toyota Avalon’s tire pressure, tread condition, and sidewalls for cuts, bulges, or cracking. It also helps to look for slow air loss, confirm the tires match side to side on each axle, and make sure the wheel size and tire size are appropriate for the trim.
Longer highway use places more importance on basic condition than appearance alone. A tire that is the correct size but underinflated, unevenly worn, or mounted on an unsuitable wheel can compromise ride quality and confidence, so a careful inspection is worthwhile before the trip begins.
