The 2026 Mercedes-Benz EQS 450 sits firmly in the modern luxury EV space, where quiet cruising, substantial curb weight, and large-diameter wheel packages all shape tire selection more than nostalgia or restoration concerns. On this exact model, tire fitment centers on two radial sizes, 255/45R20 and 265/40R21, so the first step is confirming which wheel package is on the car. Within the 20-inch fitment, choices include different radial series and sidewall presentations ranging from blackwall to raised white letter and redline. For an EQS used on the road as intended, wheel diameter, tire profile, and the car's current wheel setup matter more than simply matching the brand name.
Which Tire Size Is Right for The 2026 Mercedes-Benz EQS 450
The 2026 Mercedes-Benz EQS 450 uses two primary tire sizes, and the difference comes down first to wheel diameter. Both are radial metric sizes, but one fits a 20-inch rim and the other fits a 21-inch rim, so confirming the actual wheel package on the car is the key first step before comparing tire options.
A 255/45R20 tire uses a 255-millimeter nominal section width, a 45-series profile, radial construction, and a 20-inch rim. On the 2026 Mercedes-Benz EQS 450, this is a modern radial fitment that suits the car's contemporary wheel-and-tire layout rather than an older bias-ply sizing system. Available choices in this size include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments across several tire series. This size is the one to evaluate if the car is equipped with 20-inch wheels and the goal is to compare style and product character within that wheel package.
A 265/40R21 tire uses a 265-millimeter nominal section width, a 40-series profile, radial construction, and a 21-inch rim. For the 2026 Mercedes-Benz EQS 450, this size represents the larger wheel fitment, so it should be matched to an actual 21-inch wheel rather than chosen by appearance alone. Its lower-profile metric format signals a modern performance-oriented tire shape typical of large-diameter luxury applications. This size is the right one to check when the EQS carries 21-inch wheels and the main fitment question is wheel compatibility rather than deciding between vintage-style sidewall treatments.
Sub-model fitment is straightforward here, but wheel choice still matters. The EQS 450 4Matic uses the same two radial size paths, so selecting tires starts with confirming whether the car is running 20-inch or 21-inch wheels.

Tire Size & Fitment
What tire size fits a 2026 Mercedes-Benz EQS 450?
The 2026 Mercedes-Benz EQS 450 uses two primary tire sizes: 255/45R20 and 265/40R21. Both are radial metric sizes, so the correct choice depends on which wheel package is on the car rather than on a bias-ply-versus-radial decision.
The practical step is to confirm the actual wheel diameter before ordering tires. A 20-inch wheel requires the 255/45R20 fitment, while a 21-inch wheel requires 265/40R21, and those are not interchangeable simply because both belong to the same model family.
What size rim does a 2026 Mercedes-Benz EQS 450 use?
The 2026 Mercedes-Benz EQS 450 uses either a 20-inch or 21-inch rim, depending on the tire size fitted to the vehicle. The 255/45R20 size matches a 20-inch rim, and the 265/40R21 size matches a 21-inch rim.
Checking the wheel itself is important because the tire's final number only works with that matching rim diameter. Once the wheel diameter is confirmed, compare the tire's width and profile with the car's current setup, especially if the EQS has been fitted with different wheels than it left the showroom with.
Do all 2026 Mercedes-Benz EQS 450 sub-models use the same tire size?
The covered 2026 Mercedes-Benz EQS 450 4Matic follows the same overall fitment pattern, using 255/45R20 and 265/40R21 as the applicable radial sizes. That means the fitment path stays consistent across the sub-models shown for this vehicle.
Even with that shared pattern, the exact tire to buy still depends on the wheels currently installed on the car. Verifying the wheel diameter on the specific EQS matters more than relying on the sub-model name alone, especially if optional wheels or later wheel changes are part of the vehicle's history.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2026 Mercedes-Benz EQS 450?
Start with the basic fitment details: the tire must match the 255/45R20 size and a 20-inch wheel. From there, the meaningful differences are the tire series, sidewall style, construction details within the radial category, and any rim-width specifications that apply to the product.
This size is available in several distinct product styles, so the real choice is how the tire will be used and how you want it to look on the car. A blackwall presentation keeps things understated, while raised white letter or redline versions create a more custom visual effect on the EQS.
What sidewall styles are available for 2026 Mercedes-Benz EQS 450 tires?
Within the available 255/45R20 products for the 2026 Mercedes-Benz EQS 450, sidewall choices include blackwall, raised white letter, and redline. Those options create a noticeably different appearance even when the tire size itself remains the same.
Sidewall treatment is mainly an appearance decision, but it helps define whether the car looks more subtle or more customized. Once the correct size and wheel diameter are settled, sidewall style becomes one of the easiest ways to narrow the field without changing the core fitment.
What brands offer tires for the 2026 Mercedes-Benz EQS 450?
For the 255/45R20 fitment on the 2026 Mercedes-Benz EQS 450, available brands include BFGoodrich, Nitto, and Pro-Trac. Those choices cover several radial tire series rather than a single uniform product type.
Brand alone should not be the only filter. It makes more sense to compare the exact tire series, sidewall presentation, and wheel-compatibility details within the correct size, especially on a large luxury EV where the installed wheel package determines the fitment before any styling preference comes into play.
Restoration & Appearance
Which tire should I choose for a period-style 2026 Mercedes-Benz EQS 450?
A period-style approach is not really the main concern with a 2026 Mercedes-Benz EQS 450, since it is a current-era luxury EV with modern radial metric sizing. The better starting point is choosing the correct wheel diameter first, then selecting a tire that matches the car's intended appearance and road use.
Within the available 255/45R20 choices, appearance differences come more from sidewall treatment and tire series than from vintage construction cues. Blackwall options keep the look contemporary, while raised white letter or redline versions move the car toward a more personalized presentation without changing the underlying size.
How does tire construction affect the appearance of a restored 2026 Mercedes-Benz EQS 450?
On a 2026 Mercedes-Benz EQS 450, tire construction is less about restoration authenticity and more about staying within the modern radial format the car uses. Both primary sizes are radial, so visual differences come from profile, wheel diameter, and sidewall styling rather than from a choice between bias-ply and radial construction.
That makes appearance decisions more straightforward than on older collector vehicles. Once the correct 20-inch or 21-inch fitment is confirmed, the owner can focus on whether the car should keep a clean blackwall look or take on a more distinctive custom touch through raised white letter or redline sidewalls.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2026 Mercedes-Benz EQS 450?
Yes. Wheel changes, suspension alterations, and body-clearance changes can all affect tire fitment on a 2026 Mercedes-Benz EQS 450, even when the tire size looks close to the original setup. That matters especially on a vehicle using 20-inch and 21-inch wheel packages with relatively low-profile radial tires.
A modified EQS should be checked for actual wheel diameter, wheel width, and clearance at full steering lock and suspension travel before tires are selected. Large modern wheels leave less room for casual substitutions, so the current setup on the car matters more than assuming every EQS 450 uses the same wheel-and-tire package.
What should I inspect before driving a 2026 Mercedes-Benz EQS 450 on new tires?
Before road use, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure the tires are seated and inflated properly. It is also smart to look over the valve stems, tread surface, and sidewalls for any cuts, bulges, or shipping damage before the car goes back into regular service.
On a heavy, modern luxury EV, alignment condition and suspension health matter almost as much as the tires themselves. Uneven wear patterns, vibration, or a steering pull should be addressed early, since those issues can shorten tire life quickly and make it harder to judge whether the fitment is working as intended.
How often should tires on a 2026 Mercedes-Benz EQS 450 be inspected?
Tires on a 2026 Mercedes-Benz EQS 450 should be inspected regularly, not just at replacement time. A quick check for pressure loss, uneven tread wear, cuts, punctures, or sidewall damage is worthwhile every month and again before longer trips or after any impact with road hazards.
Routine inspection matters because low-profile radial tires can show wear or damage quickly if alignment, inflation, or road conditions are working against them. Looking over all four tires on a schedule also helps catch wheel-damage or clearance issues early, especially if the car has optional wheels or any changes from its original setup.
