The 1998 Mercedes-Benz E420 sits in the W210 era, a period when Mercedes balanced traditional E-Class comfort with V8 power and a more modern chassis feel. It appeals to owners who want a refined late-1990s sedan that still carries strong road presence and understated performance character. Tire fitment depends on configuration, with the Base using 215/55R16 radials and the Sport using 235/45R17 radials. That creates a real choice not just in size, but in wheel diameter, sidewall appearance, and tire series. For an E420 that is driven, shown, or preserved, the right starting point is confirming whether the car is a Base or Sport model and matching the tire to that setup.
Which Tire Size Is Right for The 1998 Mercedes-Benz E420
The 1998 Mercedes-Benz E420 uses two primary tire sizes, and the correct one depends on sub-model and wheel diameter. The Base model uses a 16-inch radial tire, while the Sport model uses a 17-inch radial tire. Before comparing brands or tread styles, confirm whether the car is a Base or Sport and verify the wheel diameter currently on the vehicle, especially if wheels have been changed over the years.
A 215/55R16 tire is a metric radial size with a 215-millimeter section width, a 55-series profile, and fitment for a 16-inch rim. On the 1998 Mercedes-Benz E420, this size is used on the Base model and keeps the fitment in a modern radial format suited to the car's original late-1990s design era. Available choices include BFGoodrich blackwall performance styling as well as American Classic radial options with redline or wide whitewall sidewalls. This size makes sense for owners who want to stay with the Base model wheel setup while choosing between a sportier or more restoration-inspired visual presentation.
A 235/45R17 tire is a metric radial size with a 235-millimeter section width, a 45-series profile, and fitment for a 17-inch rim. On the 1998 Mercedes-Benz E420, this size belongs to the Sport model and reflects a lower-profile, larger-diameter wheel package than the Base setup. Product choices in this size center on blackwall radials from BFGoodrich and Nitto, with distinctions between tire series and rim-width compatibility. This is the size to evaluate when the car retains its Sport configuration and the goal is preserving the correct wheel-and-tire relationship for that version.
Tire fitment changes between the covered 1998 Mercedes-Benz E420 sub-models, so identifying the exact version matters before selecting a tire. The main difference is wheel diameter, with one sub-model using a 16-inch setup and the other using a 17-inch setup.

1998 Mercedes-Benz E420 Base
The 1998 Mercedes-Benz E420 Base uses a 215/55R16 radial tire. That keeps the selection focused on the correct 16-inch fitment while leaving room to choose between blackwall, redline, or wide whitewall presentation depending on how the car is used and shown.
The 1998 Mercedes-Benz E420 Sport uses a 235/45R17 radial tire. Tire selection here starts with confirming the 17-inch wheel setup, then comparing available blackwall radial choices by tire series and wheel-width compatibility.
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 1998 Mercedes-Benz E420?
The 1998 Mercedes-Benz E420 uses two tire sizes depending on sub-model. The Base model uses 215/55R16, while the Sport model uses 235/45R17. Both are radial tire fitments, but they are tied to different wheel diameters and should be treated as separate setups rather than interchangeable starting points.
The first step is confirming whether the car is a Base or Sport model and checking the wheel diameter currently installed. A car that has been modified with different wheels should be measured directly before choosing a tire, since the correct tire must match both the vehicle configuration and the actual rim on the car.
What size rim does a 1998 Mercedes-Benz E420 use?
A 1998 Mercedes-Benz E420 uses either a 16-inch or 17-inch rim, depending on sub-model. The Base model is paired with a 16-inch wheel and 215/55R16 tires, while the Sport model uses a 17-inch wheel with 235/45R17 tires. The tire size and rim diameter need to stay matched.
Checking the wheel itself matters because tire size cannot be selected by model name alone when two rim diameters are possible. Look at the existing tire sidewall or wheel markings, and confirm that the tire being considered matches the actual rim diameter before comparing tread pattern, sidewall style, or tire series.
Why does the 1998 Mercedes-Benz E420 have more than one tire size?
The 1998 Mercedes-Benz E420 has more than one tire size because the Base and Sport sub-models use different wheel-and-tire packages. The Base model uses 215/55R16, while the Sport model uses 235/45R17. Both belong to the same model year, but they are not the same fitment configuration.
That difference affects tire selection immediately, since each size fits a different rim diameter and creates a different visual and handling setup. Anyone replacing tires should start by identifying the sub-model and verifying the wheels now on the car, especially if it has changed hands or may have received aftermarket wheels at some point.
Choosing the Right Tire
What should I consider when choosing a tire for a 1998 Mercedes-Benz E420?
Start with the correct tire size for the sub-model: 215/55R16 for the Base or 235/45R17 for the Sport. From there, compare construction, brand, tire series, sidewall style, and wheel-width compatibility where it is stated. On this E420, the real choice is not bias-ply versus radial, but which radial best suits the car's setup and use.
A Base model owner may also weigh appearance, since that size includes blackwall, redline, and wide whitewall options. Sport model owners are choosing among blackwall performance-oriented radials, so the key checks become proper rim match, intended driving use, and whether the car still retains its original wheel configuration.
What sidewall styles are available for 1998 Mercedes-Benz E420 tires?
Sidewall style depends on the tire size used on the 1998 Mercedes-Benz E420. In 215/55R16 for the Base model, available styles include blackwall, redline, and wide whitewall. In 235/45R17 for the Sport model, the available choices are blackwall radials, which keep the appearance more contemporary and performance-oriented.
That makes sidewall choice especially important for a Base model owner who wants to influence the car's presentation without changing the primary size. The best approach is to select the correct fitment first, then choose the sidewall treatment that matches the car's look, whether the goal is understated road use or a more distinctive show-oriented appearance.
What brands offer tires for the 1998 Mercedes-Benz E420?
Tires for the 1998 Mercedes-Benz E420 are available from BFGoodrich, American Classic, and Nitto, depending on the size. BFGoodrich appears in both 215/55R16 and 235/45R17, American Classic covers 215/55R16 with appearance-focused sidewall options, and Nitto is available in 235/45R17 for the Sport setup.
Brand choice should be considered alongside the size and type of tire rather than by name alone. Some options lean toward traditional styling, while others focus on modern blackwall radial presentation, so the right comparison is between the available tires that match the car's sub-model, wheel diameter, and intended use.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Mercedes-Benz E420?
A period-style 1998 Mercedes-Benz E420 tire choice starts with the correct sub-model fitment. The Base uses 215/55R16, while the Sport uses 235/45R17, and both are radial sizes appropriate to the car's era. For appearance, the Base model offers the widest visual range because that size is available in blackwall, redline, and wide whitewall form.
Selecting among them depends on how closely the car is being preserved versus personalized in period style. Owners pursuing strict originality should compare the car against marque references, archived photos, or model-specific documentation, while owners focused on era-appropriate presentation can use the correct size as the foundation and then choose the sidewall look that suits the build.
How does tire choice affect the appearance of a restored 1998 Mercedes-Benz E420?
Tire choice has a noticeable effect on a restored 1998 Mercedes-Benz E420 because the sidewall and wheel relationship strongly influence how the car sits visually. A 215/55R16 Base model can be shown with blackwall, redline, or wide whitewall styling, while the 235/45R17 Sport setup stays within a lower-profile blackwall presentation.
That means appearance decisions should follow fitment, not replace it. Staying with the proper size for the sub-model preserves the intended proportions, and then the sidewall treatment can be used to shape the final look. On a late-1990s Mercedes, even a subtle change in sidewall style can shift the car from factory-inspired understatement to a more customized visual statement.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Mercedes-Benz E420?
Yes, modifications can affect tire fitment on a 1998 Mercedes-Benz E420 even when the tire size sounds close to the original specification. Wheel changes, different rim widths, altered offsets, suspension changes, or body modifications can all influence whether a given tire clears properly and sits correctly on the car.
That matters even more here because the E420 already has two distinct factory-style fitment paths: 16-inch Base and 17-inch Sport. A modified car should be checked directly for wheel diameter, width, and available clearance before replacement tires are chosen, since the model name alone does not guarantee that the car still retains its original setup.
What should I inspect before driving a 1998 Mercedes-Benz E420 on new tires?
Before driving a 1998 Mercedes-Benz E420 on new tires, inspect the wheels for correct diameter and condition, confirm that the tire size matches the sub-model setup, and check inflation carefully. It is also wise to look over suspension and steering components, since worn parts can affect how a fresh set of tires behaves on the road.
A short, careful road test should follow installation so any rubbing, vibration, or pull can be caught early. After the first miles, recheck pressure and give the tires another visual inspection. That simple routine helps confirm that the new tires are seated properly, clearing the car correctly, and working with the vehicle's present wheel-and-suspension condition.
How often should tires on a 1998 Mercedes-Benz E420 be inspected?
Tires on a 1998 Mercedes-Benz E420 should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Look for pressure loss, irregular wear, cuts, bulges, and age-related cracking. On a collector-minded or lightly used E-Class, visual condition can matter as much as tread depth.
Monthly pressure checks are a smart baseline, and a closer inspection before longer drives is worthwhile. Cars that sit can develop issues without accumulating many miles, so the owner should not rely on appearance alone from a distance. A hands-on check of tread, sidewall condition, and valve areas helps keep the correct Base or Sport tire setup road-ready.
