Mercedes-Benz CLE300 Tires

Mercedes-Benz CLE300 uses five tire sizes across the 2024, 2025, and 2026 model years: 245/45R18 on 18-inch rims, 245/40R19 on 19-inch rims, 275/35R19 on 19-inch rims, 245/35R20 on 20-inch rims, and 275/30R20 on 20-inch rims. Every listed size is a radial metric fitment, and each of the three model years shows the same group of available sizes rather than a year-by-year size change.

The practical step is to match the tire to the wheel that is actually on the car, not just to the model year. Mercedes-Benz CLE300 may use different wheel packages and may also use a staggered arrangement, so front and rear tires are not always the same size. Read the sidewall on the tires already fitted, confirm the wheel diameter, and compare front and rear before replacing a single tire or a full set.

On a Mercedes-Benz CLE300, 245/35R20 means the tire is 245 millimeters wide, has a sidewall height equal to 35 percent of that width, uses radial construction, and fits a 20-inch rim. The same format applies to the other CLE300 sizes as well, including 245/45R18, 245/40R19, 275/35R19, and 275/30R20. Modern Mercedes-Benz CLE300 fitments use this metric radial code rather than older numeric or alphanumeric sizing systems.

That breakdown matters because each part of the code affects fit, handling, and overall tire height. A 245/35R20 is not interchangeable with a 245/40R19 even though both are 245 mm wide, because the sidewall profile and rim diameter differ. When checking a Mercedes-Benz CLE300, confirm the complete sidewall code rather than matching only the width, since profile and wheel diameter are just as important as section width.

A 2024 Mercedes-Benz CLE300 has five tire sizes listed because the model range includes multiple wheel packages and wheel diameters within the same model year. The full set of listed sizes is 245/45R18, 245/40R19, 275/35R19, 245/35R20, and 275/30R20. That is a rim-diameter split rather than a simple one-size-fits-all arrangement, and some of those sizes are clearly wider companion fitments used with staggered setups.

The key takeaway is that year alone is not enough to choose tires for a Mercedes-Benz CLE300. Start by checking whether the car has 18-, 19-, or 20-inch wheels, then verify whether the front and rear sizes match or differ. If the car has wider rear tires than front tires, replace by axle pair or complete matched set so the handling balance and appearance stay consistent.

Mercedes-Benz CLE300 uses three rim diameters in the listed range: 18 inches, 19 inches, and 20 inches. The 245/45R18 size fits an 18-inch rim, the 245/40R19 and 275/35R19 sizes fit 19-inch rims, and the 245/35R20 and 275/30R20 sizes fit 20-inch rims. Those diameters appear across all three model years, so wheel diameter is tied to configuration rather than to a change from one year to the next.

That makes rim verification the first fitment check on any Mercedes-Benz CLE300 tire replacement. Do not estimate by overall wheel appearance, because low-profile tires can make different diameters look similar at a glance. Read the size on the existing tire sidewall or confirm the wheel specification directly, especially if the car has been optioned with larger wheels or if front and rear tire sizes are different.

To confirm the correct tire size for a 2025 Mercedes-Benz CLE300, start with the wheel diameter on the car and then verify the full size code on each axle. The listed 2025 sizes are 245/45R18, 245/40R19, 275/35R19, 245/35R20, and 275/30R20. Because Mercedes-Benz CLE300 uses multiple wheel packages within the same year, the correct answer depends on the actual wheel-and-tire combination fitted to that specific car.

Use the tire sidewall and wheel measurement as your primary guide, then make sure front and rear match what is already installed unless you are intentionally changing the full setup. A staggered Mercedes-Benz CLE300 may use narrower front and wider rear tires, so replacing only one position without checking the other can create a mismatch. Confirming the complete size at each corner prevents ordering by year alone and getting the wrong diameter or profile.

Mercedes-Benz CLE300 tires in the listed range are offered in Blackwall sidewall style. That applies across all five fitments: 245/45R18, 245/40R19, 275/35R19, 245/35R20, and 275/30R20. The available products are contemporary radial performance tires, so the sidewall presentation is straightforward and consistent with the modern character of Mercedes-Benz CLE300.

For a Mercedes-Benz CLE300 owner, that means the main buying decision is not sidewall appearance but rather size, wheel diameter, and tire series. Blackwall styling keeps the look correct for a modern performance-luxury coupe and avoids the appearance mismatch that would come from vintage-style sidewall treatments. Once the cosmetic choice is simplified, you can focus on selecting the right combination for ride quality, steering response, and front-to-rear fitment.

Mercedes-Benz CLE300 tires in the listed range come from two brands: BFGoodrich and Nitto. Across the five sizes, the available series include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. Product counts vary by size, with some fitments offering several choices and others having a narrower selection.

That gives a Mercedes-Benz CLE300 owner room to compare tire character within the correct size rather than searching for a single brand-specific solution. When choosing among them, keep the wheel diameter and exact size as the fixed requirement, then compare the available series within that fitment. If the car uses staggered sizing, it is wise to make sure the front and rear tires belong to a compatible family so the car maintains a balanced feel.

Mercedes-Benz CLE300 fitments are offered in four tire series: BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. All of them are radial tires and all are listed in Blackwall form, but they represent different product families within the modern performance category. Availability depends on the exact CLE300 size, with some sizes carrying more series choices than others.

For the buyer, the important point is to choose the series only after the correct size has been established. A Mercedes-Benz CLE300 on 18-inch wheels cannot use a 19- or 20-inch series option, even if the tread family is appealing. Once fitment is settled, compare the available series within that one size and keep the front and rear selection consistent if the car uses staggered widths.

A Mercedes-Benz CLE300 should be stored on clean, properly inflated tires in a cool, dry, dark space away from direct sunlight, electric motors, welders, and ozone-producing equipment. Low-profile radial tires like those fitted to Mercedes-Benz CLE300 can develop flat spotting if the car sits for long periods without movement. Keeping the car on a smooth surface and avoiding prolonged contact with petroleum products or solvents will help preserve the rubber.

If the Mercedes-Benz CLE300 will be parked for an extended season, increase attention to inflation pressure and move the car periodically so one contact patch is not carrying the same load for months at a time. Many owners also use tire cradles or lift the load slightly during long storage. Good storage habits matter as much as tread depth on a lightly used car, because age and environment often determine tire condition before wear does.

Tires on a Mercedes-Benz CLE300 should be inspected regularly even if the car is driven only occasionally. Check inflation, tread condition, sidewall condition, and any signs of impact damage or irregular wear at least monthly and again before any longer drive. On a Mercedes-Benz CLE300 with staggered sizing, inspect front and rear separately because the wider rear tires may show different wear patterns than the fronts.

Frequent inspection helps catch the issues that matter most on modern low-profile tires: edge wear, punctures, sidewall scuffing, and uneven wear from alignment or pressure problems. A Mercedes-Benz CLE300 can mask early tire problems because the car is refined and stable, so visual checks are important even when the ride feels normal. If wear appears uneven from side to side or axle to axle, have the wheel alignment and suspension checked before fitting another set.

Tires on a Mercedes-Benz CLE300 should be replaced when age-related deterioration, sidewall cracking, impact damage, or hardening appears, even if the tread depth still looks usable. Collector and enthusiast cars often age out their tires before they wear them out, especially when annual mileage is low. Any Mercedes-Benz CLE300 tire that shows bulges, cuts, repeated air loss, or visible structural distress should be treated as ready for replacement regardless of remaining tread.

That is especially important on Mercedes-Benz CLE300 because low-profile tires work with less sidewall height and can be more vulnerable to road and curb damage. Do not judge condition by tread alone; evaluate the whole casing and the tire’s service life in real-world use. Replacing tires on age and condition rather than waiting for them to become visibly worn is one of the best ways to preserve ride quality, handling confidence, and wheel protection.

The listed Mercedes-Benz CLE300 tires are modern radial road tires in the correct general size families for this model range, so they are intended for public-road use when fitted in the proper size and kept in proper condition. Safety depends on matching the exact wheel diameter, maintaining even front-to-rear fitment where required, and keeping the tires properly inflated. A 19-inch Mercedes-Benz CLE300 fitment should not be substituted with an 18- or 20-inch size simply because the width appears similar.

Road safety also depends on the condition of the individual tires and wheels already on the car. Inspect for curb damage, punctures, uneven wear, and age-related deterioration before regular use. If a Mercedes-Benz CLE300 has recently changed wheel packages or had suspension work, confirm that the installed sizes still match the car correctly and that there is no interference at full steering lock or under compression.

Before driving a Mercedes-Benz CLE300, check tire pressure, visible tread and sidewall condition, and confirm that each tire size matches its wheel position. The listed fitments include both narrower 245-width sizes and wider 275-width sizes, so a staggered Mercedes-Benz CLE300 should be checked carefully to make sure front and rear tires are installed where they belong. Also look for any fresh cuts, bubbles, or impact marks that could have come from potholes or curb contact.

Those checks matter because a modern performance-luxury car can feel composed even when the tires are not in ideal shape. Make a quick walkaround part of the routine, especially after the car has been parked for some time or after driving on rough pavement. If the Mercedes-Benz CLE300 pulls, vibrates, or shows warning signs after startup, stop and investigate rather than assuming the issue will clear up on its own.

A Mercedes-Benz CLE300 should be driven at legal, road-appropriate speeds that respect the condition, inflation, and exact specification of the tires currently fitted. The listed offerings are modern radial tires in performance-oriented sizes, but real-world safe speed is always limited by tire age, road surface, load, weather, and the overall condition of the vehicle. An older or damaged tire on a Mercedes-Benz CLE300 should never be treated as if it can safely deliver the same margin as a fresh, properly maintained one.

The sensible approach is to think of tire speed potential as a system question, not just a sidewall-code question. Keep the Mercedes-Benz CLE300 on matching, properly inflated tires and avoid sustained high-speed use if there is any doubt about age, wear pattern, or impact history. Smooth, conservative driving is especially wise until you know how the current set behaves and whether the car’s alignment and balance are fully sorted.
