2020 McLaren Tire Fitment Guide

2020 McLaren vehicles use six sizes across four model lines, and the fitments are model-specific. The 570S and 600LT use 225/35R19 front and 285/35R20 rear. The 720S uses 245/35R19 front and 305/30R20 rear. The GT uses 225/35R20 front and 295/30R21 rear. Rim width guidance appears within the available product range for 245/35R19 at 8.0 to 9.5 inches and for 285/35R20 at 9.5 to 11.0 inches.

That means the first step is identifying the exact model, then confirming front and rear wheel diameters before choosing tires. A 19-inch front size from a 570S or 600LT does not automatically interchange with the GT's 20-inch front fitment, and a 20-inch rear on a 720S is different from the GT's 21-inch rear. Treat the car as a staggered setup and verify both axle sizes together, not one tire at a time.

On a 2020 McLaren, 225/35R19 is a metric radial size. The 225 is the section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. Within the 2020 McLaren range, this size is used as a front tire on the 570S and 600LT rather than across every model.

That decoding matters because modern high-performance sizes can look similar at a glance while fitting different wheels and serving very different axle positions. A 225/35R19 is not interchangeable with 225/35R20 simply because the width and profile match; the wheel diameter is different. When you confirm the size on the car, read the full sidewall code and make sure it matches the front or rear position you are replacing.

No. The 2020 McLaren range uses different front and rear tire combinations depending on the model. The 570S and 600LT share one staggered package, the 720S uses a wider front and rear combination, and the GT moves to a different front size and a 21-inch rear. Every size in this year and make is radial, but the dimensions are not universal.

That makes model identification essential before ordering. If you know only that you have a 2020 McLaren, you still have several possible front diameters and rear diameters in play. The quickest way to avoid a mismatch is to verify the model, then compare the sidewall code on both front and rear tires or confirm the wheel diameters directly on the car.

Sidewall appearance varies by size in the 2020 McLaren range. The 245/35R19 and 225/35R20 offerings are Blackwall only. The 285/35R20 size is available in Blackwall and RWL form, while 305/30R20 comes in Blackwall, RWL, and Redline. Those alternate sidewall treatments appear in a few rear sizes rather than across the full staggered set.

Most 2020 McLaren owners looking for an appearance close to modern exotic-car practice will stay with Blackwall tires, since that look aligns naturally with the era and the brand's understated wheel-and-body design language. RWL and Redline versions can change the visual character more dramatically, so they are best chosen intentionally rather than as a default replacement. If appearance matters, compare the front and rear sidewalls together so the car retains a consistent look.

BFGoodrich, Nitto, and Pro-Trac all appear in the 2020 McLaren product range. The 285/35R20 rear size for the 570S and 600LT is available from all three brands. The 245/35R19 front size for the 720S is available from BFGoodrich and Nitto, while 305/30R20 for the 720S is available from Nitto and Pro-Trac. The 225/35R20 front size for the GT appears from Nitto.

Brand choice matters most after the correct size and axle position are settled. Once you know the exact front and rear pair for your model, compare available sidewall treatments, wheel-width compatibility where stated, and the speed rating on the tire you are considering. On a modern McLaren, that is usually a more useful way to narrow the field than choosing by brand name alone.

For 2020 McLaren 720S front fitment in 245/35R19, BFGoodrich and Nitto both offer Blackwall radial tires with a W speed rating, which carries a 168 mph ceiling where marked. BFGoodrich appears in g-Force Comp 2 AS and g-Force Phenom T/A versions, while Nitto appears in the NT555 G2. Available rim-width guidance in this size spans 8.0 to 9.5 inches, and the BFGoodrich load figure shown reaches 1,433 pounds at 50 psi.

The practical comparison is less about construction, since all of them are radial, and more about the exact series, wheel-width suitability, and how closely you want to match the tire's intended character to your driving use. A buyer replacing only one axle should also pay attention to whether the front choice pairs sensibly with the rear tire already on the car. Matching ratings and general performance category across the staggered set is usually the safer path.

Rim-width guidance appears for two sizes in the 2020 McLaren range. The 245/35R19 size used on the front of the 720S fits wheels from 8.0 to 9.5 inches wide, and the 285/35R20 size used on the rear of the 570S and 600LT fits wheels from 9.5 to 11.0 inches wide. The other sizes here do not carry a wheel-width range in the available product details.

That information is especially useful when the car has aftermarket wheels or when you are confirming whether an existing wheel is suitable for a different tire brand in the same nominal size. The safest approach is to verify the actual wheel width stamped on the wheel or measured directly, then compare it with the tire's approved range. That check matters more on low-profile exotic fitments than it would on a taller sidewall collector tire.

The 2020 McLaren tire products shown here are tubeless radials where the sidewall marking identifies TL, and no tube-type fitment appears in this range. The BFGoodrich 285/35ZR20 100Y TL explicitly carries a tubeless marking, and the other modern high-performance radial sizes follow the same general construction style. Nothing in these applications points toward an inner-tube setup.

Even so, a tubeless tire still depends on wheel condition and valve-stem integrity to hold air properly. If the car has sat for long periods, inspect the bead seat areas, the valve stems, and the age of the current tires before assuming a simple size match is enough. Exotic cars often spend more time parked than driven, and sealing issues can show up long before tread wear becomes the reason for replacement.

A 2020 McLaren should be stored in a cool, dry, dark space with the tires protected from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment. Keep the tires clean, avoid long contact with standing moisture or petroleum products, and maintain inflation rather than letting the car sit on partially deflated tires. Low-profile radial tires resist flat-spotting better than old bias-ply designs, but long static periods can still create temporary shape change and stress the casing.

For a car that spends much of its life in a collection, periodic movement is helpful. Rolling the car occasionally changes the load patch and reduces the chance of one area of the tire carrying the weight for months at a time. If the storage period will be extended, some owners use stands or cradles as part of a broader preservation routine, but tire pressure and environmental control still matter either way.

On a 2020 McLaren, tire age is usually more important than mileage alone. Collector and exotic cars often cover very few miles, yet the rubber still ages from heat cycles, ozone, and time. A sound rule is to begin evaluating tires closely at about five to seven years from the DOT date code and to give serious replacement consideration by around ten years, even if the tread still looks serviceable.

That timeline becomes even more important on a high-performance car with low-profile tires, where handling precision and casing integrity matter as much as tread depth. The date code on the sidewall gives the week and year of manufacture, and that should be part of every inspection. If the car has spent time parked, age-related cracking or hardening can make an older tire a poor choice for spirited driving long before it appears worn out.

Tires on a 2020 McLaren should be inspected before every drive and again before any longer outing. Check pressure, tread condition, sidewall cracking, cuts, bulges, punctures, and any uneven wear that could point to alignment or suspension issues. Because these are low-profile radial fitments, it is also worth looking closely at the rim protector area and the inner sidewall after pothole contact or curb impact.

A routine inspection takes only a few minutes and can prevent much larger problems on an exotic car that may sit between drives. Pay special attention if the car has been stored for a season, recently detailed, or driven on rough pavement. The goal is not only to avoid a roadside failure, but also to preserve ride quality and steering response by catching small issues before they become expensive ones.

Yes, provided the tires are the correct size for the model, in sound condition, and used within their rated limits. The speed-rated products shown here include W and Y examples, with W rated to 168 mph and Y rated to 186 mph or higher where marked. Those ratings are well beyond ordinary U.S. highway speeds, and every size in this range is a modern radial rather than an older construction type.

In real use, the larger safety question on a 2020 McLaren is often tire age, inflation, and overall vehicle condition rather than the raw speed symbol on the sidewall. A modern supercar can expose a weak tire quickly if the car has been stored, underinflated, or driven on old rubber. For normal highway use, a fresh, correctly sized tire on a mechanically sound car is the foundation to focus on.

Inflation pressure on a 2020 McLaren should follow the vehicle manufacturer's recommendation for the exact model and axle, not a copied figure from another McLaren or another tire size. One 245/35R19 product in this range carries a maximum load of 1,433 pounds at 50 psi, but that is a tire rating reference rather than a blanket operating pressure for every 2020 McLaren application. Pressure targets can differ substantially front to rear on staggered exotic-car setups.

The best practice is to start with the factory placard or owner's manual for the car, then confirm that the tire's own load and pressure limits are respected. Do not transfer a figure from a 720S front tire to a 570S rear or to a GT, even if the aspect ratio looks similar. On a high-performance car, correct pressure affects steering, ride, wear, and stability all at once.

Before a longer drive in a 2020 McLaren, inspect all four tires for cracking, cuts, bulges, punctures, and uneven wear, then verify cold inflation pressures and look over the valve stems and wheel lips. Check the age of the tires if the car has been in storage, and make sure the spare or mobility kit situation is understood before departure. On a staggered setup, confirm that the front and rear sizes match the model exactly.

Tires are only one part of the pre-drive routine on a modern exotic, so it also makes sense to include brakes, fluids, battery condition, and any warning lights in the check. A McLaren that has been sitting can feel fine at low speed and still reveal problems once heat builds into the tires and driveline. A careful inspection before the trip is far easier than troubleshooting a preventable issue away from home.
