The 2019 Toyota Trucks Tundra sits in the full-size pickup market as a durable, body-on-frame truck known for towing, work use, and everyday road duty. Its trim and wheel package matter because tire fitment is not the same across the lineup. This Tundra uses three primary radial sizes: 275/55R20, 275/65R18, and 255/70R18, depending on the sub-model and wheel setup. That means the real choice starts with confirming whether the truck has 18-inch or 20-inch wheels, then narrowing the selection by intended use, sidewall style, and tire design. For a stock truck, correct size and wheel match come before any comparison of tread character or appearance.
Which Tire Size Is Right for The 2019 Toyota Trucks Tundra
Three primary tire sizes apply to the 2019 Toyota Trucks Tundra, and they vary by sub-model and wheel setup. Two sizes use 18-inch rims, while one uses a 20-inch rim, so wheel diameter is the first thing to confirm before choosing a tire. Once that is settled, the decision becomes selecting the right radial tire for the truck's trim, intended use, and wheel configuration.
Fit(s): 1794 Edition w/aluminum wheels, Limited w/aluminum wheels, Platinum w/aluminum wheels, SR5 w/aluminum wheels, and TRD Sport w/aluminum wheels
Construction: Radial|Rim: 20 in
The size 275/55R20 uses a metric sizing system: 275 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2019 Toyota Trucks Tundra, this is a modern radial fitment used on certain aluminum-wheel trims. Its lower-profile look relative to the 18-inch options gives it a distinct wheel-to-tire presentation. This size is the right place to start when the truck already wears 20-inch wheels and the goal is to keep the original wheel diameter and overall fitment approach.
Fit(s): 1794 Edition w/aluminum wheels, Limited w/aluminum wheels, SR5 w/aluminum wheels, and TRD Pro w/aluminum wheels
Construction: Radial|Rim: 18 in
The size 275/65R18 is a metric radial tire with a 275-millimeter nominal section width, a 65-series profile, and an 18-inch rim diameter. For the 2019 Toyota Trucks Tundra, it appears on several aluminum-wheel sub-models, including trims where tire choice may lean toward a more truck-oriented look and use. Available product choices in this size include BFGoodrich, with an All Terrain T/A KO2 offering and raised white letter sidewall styling. This size deserves a closer look when the truck has 18-inch aluminum wheels and the owner wants to compare road use with a more all-terrain-oriented tire character.
The size 255/70R18 follows the same metric radial format, with 255 indicating nominal width in millimeters, 70 indicating aspect ratio, and 18 identifying rim diameter. On the 2019 Toyota Trucks Tundra, this size is tied to certain steel-wheel configurations rather than the broader aluminum-wheel group. That makes it more configuration-specific than the other sizes on this page. It should be evaluated by owners who want to keep the truck matched to its existing 18-inch steel-wheel setup instead of assuming every 18-inch Tundra uses the wider 275-section tire.
Sub-model fitment matters on the 2019 Toyota Trucks Tundra because tire size changes with trim and wheel type. Some versions share more than one approved size, while others are tied to one specific radial size, so confirming the exact sub-model and wheel setup avoids choosing the wrong rim diameter or section width.

2019 Toyota Trucks Tundra 1794 Edition w/aluminum wheels
The 2019 Toyota Trucks Tundra 1794 Edition w/aluminum wheels uses either of two radial tire sizes, which means wheel diameter must be confirmed before narrowing the tire choice. Once the 18-inch or 20-inch setup is verified, selection becomes a matter of matching the truck's current wheels and intended driving use.
2019 Toyota Trucks Tundra Limited w/aluminum wheels
The 2019 Toyota Trucks Tundra Limited w/aluminum wheels can use two different radial sizes, so it is not enough to identify the trim alone. Checking whether the truck has 18-inch or 20-inch wheels is the key first step before comparing available tire designs and specifications.
2019 Toyota Trucks Tundra Platinum w/aluminum wheels
The 2019 Toyota Trucks Tundra Platinum w/aluminum wheels uses a single primary radial size tied to its 20-inch wheel setup. That makes tire selection more straightforward, with the main focus shifting from size confirmation to choosing the right tire style and use pattern within that fitment.
The 2019 Toyota Trucks Tundra SR w/steel wheels uses one primary radial size associated with its 18-inch steel-wheel configuration. For tire selection, the priority is staying with that wheel-based fitment rather than assuming the wider aluminum-wheel sizes apply to this version.
The 2019 Toyota Trucks Tundra SR5 w/aluminum wheels spans two radial sizes, so the sub-model alone does not settle the fitment question. Confirming the actual wheel diameter on the truck is essential before comparing tire options or moving toward a more road-oriented or truck-oriented tread style.
The 2019 Toyota Trucks Tundra SR5 w/steel wheels uses a single 18-inch radial tire size tied to that steel-wheel setup. That helps simplify selection, especially for owners trying to keep the truck matched to its current wheel type without crossing over into aluminum-wheel fitments.
2019 Toyota Trucks Tundra TRD Pro w/aluminum wheels
The 2019 Toyota Trucks Tundra TRD Pro w/aluminum wheels uses one 18-inch radial tire size. Since this fitment is size-specific, the main decision is choosing an appropriate tire within that size while confirming the truck still has its intended wheel setup.
2019 Toyota Trucks Tundra TRD Sport w/aluminum wheels
The 2019 Toyota Trucks Tundra TRD Sport w/aluminum wheels uses a single 20-inch radial tire size. That means the fitment question is usually straightforward, and the next step is comparing tire type and appearance within the correct size for the existing wheels.
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.

These FAQs focus on the tire sizes used on the 2019 Toyota Trucks Tundra, how fitment changes by sub-model and wheel type, and what to consider when comparing radial tires for road use, truck duty, and routine inspection.
Tire Size & Fitment
What tire size fits a 2019 Toyota Trucks Tundra?
The 2019 Toyota Trucks Tundra uses three primary radial tire sizes: 275/55R20, 275/65R18, and 255/70R18. The correct one depends on the truck's exact sub-model and wheel setup, so there is not one universal size across the entire Tundra lineup.
The most important first step is checking whether the truck has 18-inch or 20-inch wheels, then matching that to the specific trim and wheel type. Steel-wheel and aluminum-wheel configurations do not always use the same size, and some sub-models can use more than one fitment, so the actual wheel package matters before comparing tires.
What size rim does a 2019 Toyota Trucks Tundra use?
The 2019 Toyota Trucks Tundra uses either an 18-inch or 20-inch rim, depending on the sub-model and wheel package. The 275/55R20 size fits a 20-inch rim, while both 275/65R18 and 255/70R18 fit 18-inch rims.
Rim diameter should be confirmed before anything else because two of this truck's tire sizes share an 18-inch wheel, while another uses a 20-inch wheel. Even among 18-inch setups, the tire width and profile are not always the same, so checking the actual wheel and the exact trim prevents a mismatch.
Why does the 2019 Toyota Trucks Tundra have more than one tire size?
Multiple tire sizes appear on the 2019 Toyota Trucks Tundra because fitment changes by sub-model and wheel type. Some aluminum-wheel trims can use either 275/55R20 or 275/65R18, while certain steel-wheel versions use 255/70R18, and single-size trims stay tied to one setup.
That means the tire decision is really a configuration decision first. A Tundra owner should confirm the exact trim, wheel material, and wheel diameter already on the truck before selecting a replacement tire. That approach keeps the search focused on the size that matches the current wheel package rather than the broader model name alone.
Choosing the Right Tire
What should I consider when choosing a tire for a 2019 Toyota Trucks Tundra?
Start with the correct size for the truck's sub-model and wheel setup, because the 2019 Toyota Trucks Tundra uses 275/55R20, 275/65R18, or 255/70R18 depending on configuration. After size, the main factors are radial tire design, rim compatibility, intended use, and how aggressive or road-focused the tire needs to be.
A truck used mainly on pavement may call for a different tread character than one that sees dirt, gravel, or heavier work use. It also helps to compare sidewall styling, load capacity figures, and wheel-width suitability where those specs are available, especially if the truck no longer has its original wheel package.
What sidewall styles are available for 2019 Toyota Trucks Tundra tires?
Among the currently visible product choices for the 2019 Toyota Trucks Tundra, 275/65R18 includes an RWL sidewall option, meaning raised white letters. That style gives the tire a more traditional truck presentation than a plain black sidewall.
Sidewall style does not change the need to match the correct tire size, rim diameter, and wheel setup. Once those basics are confirmed, appearance becomes a secondary choice that can help the truck lean more toward a classic truck look or a cleaner, more understated presentation depending on the tire selected.
What brands offer tires for the 2019 Toyota Trucks Tundra?
Current product coverage for the 2019 Toyota Trucks Tundra includes BFGoodrich in 275/65R18. The available example is from the All Terrain T/A KO2 line, giving that size a clearly truck-oriented option within the correct radial fitment.
Brand is only one part of the decision, especially on a Tundra with several possible sizes across the model range. It still makes sense to confirm the exact size first, then compare construction, sidewall treatment, rim-width compatibility, and load-related specs so the tire suits both the wheel package and the truck's intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Toyota Trucks Tundra?
For a period-style 2019 Toyota Trucks Tundra, the best starting point is the original size family used by the truck's exact sub-model and wheel setup. Because this is a modern full-size pickup with radial fitments only, keeping the correct size and rim diameter usually does more for the truck's authentic appearance than chasing unusual alternative sizing.
Appearance choices then come down to tire design and sidewall presentation within the proper fitment. A raised white letter option can give certain trims a more truck-oriented look, while a more understated sidewall keeps the presentation cleaner. Owners focused on strict originality should also compare the tire choice against photos, window-sticker references, or marque-specific documentation.
Does correct tire fitment matter for a 2019 Toyota Trucks Tundra restoration?
Correct tire fitment matters because the 2019 Toyota Trucks Tundra does not use one universal size across the range. A restoration-minded owner should match the truck's trim and wheel package to the right tire size first, since an 18-inch steel-wheel setup and a 20-inch aluminum-wheel setup create different visual and fitment outcomes.
Using the proper size helps preserve the truck's intended stance and keeps the wheel-to-tire relationship in line with the original configuration. Even on a newer collector-era truck, details like wheel diameter, tire profile, and sidewall style affect the finished look, so fitment accuracy supports both appearance and practical compatibility.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Toyota Trucks Tundra?
Yes. Wheel changes, suspension modifications, leveling kits, lowering, or body alterations can all affect tire fitment on a 2019 Toyota Trucks Tundra, even when the tire size matches a factory-style size used somewhere in the lineup. Offset, wheel width, and available clearance can change the result.
A truck with aftermarket wheels or altered ride height should be checked for steering clearance, fender clearance, and suspension travel before settling on a tire. That is especially important on a Tundra with both 18-inch and 20-inch fitments in the same model year, because matching the size code alone does not account for wheel and chassis changes.
What should I inspect before driving a 2019 Toyota Trucks Tundra on new tires?
Before driving a 2019 Toyota Trucks Tundra on new tires, inspect the wheel condition, confirm the tire size matches the truck's actual wheel diameter, and check that inflation is set appropriately for the installed tire. It also helps to look over the suspension, alignment condition, and lug hardware before regular road use.
After installation, watch for any rubbing at full steering lock, unusual vibration, or uneven contact that could point to alignment or wheel-fitment issues. A short test drive followed by a second visual inspection is worthwhile, especially if the truck has seen wheel changes, off-road use, or previous tire wear patterns that suggest other problems.
How often should tires on a 2019 Toyota Trucks Tundra be inspected?
Tires on a 2019 Toyota Trucks Tundra should be inspected regularly, not just when tread looks worn. Frequent visual checks for uneven wear, cuts, punctures, sidewall damage, bulges, and air loss are especially useful on a truck that tows, hauls, or sees mixed road conditions.
Monthly pressure checks are a smart habit, and a closer inspection before longer trips adds another layer of caution. It also helps to look for signs of age-related cracking on trucks that sit for extended periods. Catching those issues early can prevent vibration, irregular wear, and avoidable fitment or handling problems on the road.
