In 2021 McLaren offered a focused range of modern supercars, from the highly capable 720S to the more extreme 765LT and the grand-touring GT. Each model carried McLaren’s familiar emphasis on light weight, sharp chassis tuning, and staggered tire fitments that play a major role in the way these cars look and drive. Across the 2021 McLaren lineup, three models use four radial sizes, with the 720S and 765LT sharing one front-and-rear pairing while the GT uses a different pair altogether. Before choosing a tire, the first step is confirming your exact model, since the front and rear sizes change with the model and wheel diameter.
Which Tire Size Is Right for Your 2021 McLaren
Four tire sizes are used across 2021 McLaren vehicles, and they vary by model rather than being shared across the full lineup. The real decision starts with identifying whether you have a 720S or 765LT versus a GT, because the sizes use different front and rear rim diameters depending on the model. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 2021|Fit(s): 720S, 765LT|Construction: Radial|Rim: 19 in
The 245/35R19 is a radial size with a 245-millimeter section width, a 35-series aspect ratio, and a 19-inch rim diameter. This front size is specific to the 720S and 765LT, and it is available from BFGoodrich and Nitto in Blackwall form with W-rated products to 168 mph. It suits owners of those two models who need the correct front fitment and want a modern radial tire matched to the car’s contemporary performance character.
Year(s): 2021|Fit(s): 720S, 765LT|Construction: Radial|Rim: 20 in
The 305/30R20 is a radial size with a 305-millimeter section width, a 30-series aspect ratio, and a 20-inch rim diameter. This rear size is specific to the 720S and 765LT, and it comes from Nitto and Pro-Trac with Blackwall, RWL, and Redline sidewall styles; Nitto carries a W speed rating to 168 mph, while the Pro-Trac versions do not show a speed letter in the size marking. It is the correct rear size for buyers sorting tires for those two supercar models and deciding between a more understated blackwall look or a more custom sidewall treatment.
Year(s): 2021|Fit(s): GT|Construction: Radial|Rim: 20 in
The 225/35R20 is a radial size with a 225-millimeter section width, a 35-series aspect ratio, and a 20-inch rim diameter. This front size belongs only to the McLaren GT, and it is available from Nitto in Blackwall form with a W speed rating to 168 mph. It is the straightforward choice for GT owners who want the proper front size for McLaren’s grand-touring model without crossing over into 720S or 765LT fitment.
Year(s): 2021|Fit(s): GT|Construction: Radial|Rim: 21-in rim
The 295/30R21 is a radial size with a 295-millimeter section width, a 30-series aspect ratio, and a 21-inch rim diameter. This rear size is exclusive to the McLaren GT and pairs with the GT’s 20-inch front fitment rather than the 19-inch front and 20-inch rear arrangement used by the 720S and 765LT. GT owners should choose this size only when confirming the car’s rear wheel fitment, since it is not interchangeable with the other 2021 McLaren rear size.
Three McLaren models are covered for 2021. Tire sizing varies by model, so year and make alone are not enough; the 720S and 765LT share one staggered setup, while the GT uses a different front-and-rear combination with a larger rear rim diameter. Select your model below to narrow the fitment history and tire choices correctly.
2021 McLaren 720S
The 2021 McLaren 720S was the core Super Series car, known for dramatic aerodynamics, very high speed capability, and a light, rigid carbon-fiber structure. Its tires mount on 19-inch front and 20-inch rear wheels, giving it the staggered setup expected of a mid-engine McLaren. That wheel pairing is shared with the 765LT, so identifying the model matters more for vehicle context and intended use than for basic size selection.
The 2021 McLaren 765LT took the 720S formula further with a sharper, more track-focused character and the longtail approach McLaren reserves for its most intense road cars. Like the 720S, it uses 19-inch front and 20-inch rear wheels with a staggered tire arrangement. Because the sizes mirror the 720S, the tire decision usually comes down to confirming front versus rear position and choosing the product style that suits how the car is used.
The 2021 McLaren GT was designed as the more relaxed, road-trip-oriented McLaren, blending supercar performance with added luggage space and touring manners. Its tire setup differs from the Super Series cars, using 20-inch front and 21-inch rear wheels. That makes model identification essential before choosing tires, since the GT does not share either of its sizes with the 720S or 765LT.
Seven products are available across four tire sizes for 2021 McLaren vehicles. The 245/35R19 has three radial choices from BFGoodrich and Nitto in Blackwall form, the 305/30R20 has three radial choices from Nitto and Pro-Trac in Blackwall, RWL, and Redline styles, and the 225/35R20 has one radial Blackwall option from Nitto.
These answers focus on the staggered tire sizes used across the 2021 McLaren range, the difference between 720S and 765LT fitment versus GT fitment, sidewall style choices in certain sizes, and the care high-performance collector cars need between drives.
Size Basics & Fitment
What tire sizes fit 2021 McLaren vehicles?
2021 McLaren vehicles use four sizes across three models. The 720S and 765LT use 245/35R19 in front and 305/30R20 in the rear, while the GT uses 225/35R20 in front and 295/30R21 in the rear. Rim diameter changes with those pairings: 19 and 20 inches for the 720S and 765LT, and 20 and 21 inches for the GT. Where rim-width guidance appears, 245/35R19 fits 8.0 to 9.5-inch rims.
That means model identification comes first, and front-versus-rear position comes second. A 305/30R20 rear for a 720S or 765LT is not the same fitment as a 295/30R21 rear for a GT, even though both are low-profile radial performance sizes. Confirm the exact model and check the wheel currently on the car before narrowing down sidewall style, brand, or tire series.
What does 245/35R19 mean on a 2021 McLaren tire?
On a 2021 McLaren, 245/35R19 is a metric radial size. The 245 is the nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. For 2021 McLaren applications, that size is used on the front of the 720S and 765LT. Available products in this size carry W speed ratings, which correspond to a 168 mph ceiling.
That decoding matters because it tells you the tire’s basic dimensions and confirms that the size belongs to a specific position on specific models, not to the whole 2021 McLaren range. It also helps you compare modern performance options without confusing front and rear fitments. If your wheel is 19 inches and your car is a 720S or 765LT, this is the front size to verify against the sidewall before moving ahead.
Do all 2021 McLaren models use the same tire size?
No. The 2021 McLaren 720S and 765LT share the same staggered setup, using 245/35R19 fronts and 305/30R20 rears, but the 2021 McLaren GT uses a different pair: 225/35R20 fronts and 295/30R21 rears. Every size in this lineup is radial, but the actual dimensions and wheel diameters vary by model. The GT stands apart most clearly because of its 21-inch rear fitment.
That separation is important because many buyers know the year and make before they know the exact model fitment details. On a 2021 McLaren, choosing by year alone can put you into the wrong front or rear diameter. If the car has been modified or the wheels have been changed, compare the sidewall size currently fitted and the actual wheel diameter before selecting a replacement.
Buying the Right Tire
What sidewall styles are available for 2021 McLaren tires?
Most 2021 McLaren tire options here are Blackwall radials, which is the expected look for a modern supercar. The 245/35R19 front size for 720S and 765LT is offered in Blackwall, and the 225/35R20 front size for the GT is also Blackwall. The 305/30R20 rear size for 720S and 765LT expands the visual options with Blackwall, RWL, and Redline versions, all in radial construction.
For an owner focused on a contemporary factory-style appearance, Blackwall is the natural choice across the lineup. RWL and Redline in the 305/30R20 rear size push the look in a more personalized direction and may appeal to a modified build or a more expressive visual theme. Since sidewall style can change the car’s overall presentation without changing the basic size, it is worth deciding on appearance before narrowing the brand or series.
What brands make tires for 2021 McLaren vehicles?
2021 McLaren fitments here are covered by BFGoodrich, Nitto, and Pro-Trac. The 245/35R19 front size for the 720S and 765LT is available from BFGoodrich and Nitto, the 305/30R20 rear size for those same models is available from Nitto and Pro-Trac, and the 225/35R20 front size for the GT is available from Nitto. All of those offerings are radial performance tires suited to modern wheel diameters and low-profile applications.
Brand choice on a 2021 McLaren often comes down to the exact size you need first, then the sidewall presentation you want. BFGoodrich and Nitto cover the 19-inch front fitment for the Super Series cars, while Pro-Trac enters the picture on the 20-inch rear with alternate sidewall styling. Once the model and tire position are confirmed, compare the available series within that size rather than assuming every brand covers every 2021 McLaren fitment.
What is the difference between BFGoodrich and Nitto in the 245/35R19 size for 2021 McLaren vehicles?
In 245/35R19 for 2021 McLaren 720S and 765LT front fitment, BFGoodrich and Nitto both offer Blackwall radial tires with W speed ratings. BFGoodrich covers the size with g-Force Comp 2 AS and g-Force Phenom T/A, while Nitto offers the NT555 G2. Weight varies among those products, with the BFGoodrich examples at 28 and 26.34 pounds and the Nitto at 25.79 pounds. Rim-width guidance is also shown on the BFGoodrich products at 8.0 to 9.5 inches.
For the buyer, that makes this less about basic compatibility and more about which series characteristics and presentation fit the car’s use. All three remain within the same essential size and speed category, so the more useful comparison is product-by-product rather than brand name alone. Check the exact wheel width, then compare the sidewall markings and series identity before deciding which front tire best suits your 720S or 765LT.
Fitting & Setup
What rim width do 2021 McLaren tires require?
Rim-width guidance appears for the 245/35R19 size used on the front of 2021 McLaren 720S and 765LT models. In that size, BFGoodrich products fit 8.0 to 9.5-inch rims. The other 2021 McLaren sizes here do not carry rim-width guidance in the same way, so the strongest direct wheel-width reference within this range is tied to that 19-inch front fitment.
That makes wheel confirmation especially important on any 2021 McLaren that may have aftermarket wheels or non-original wheel packages. Rim diameter alone is not enough; wheel width affects how the tire seats and how the sidewall sits on the wheel. Compare the wheel’s actual width against the tire maker’s approved range for the exact product you are considering rather than assuming one front or rear McLaren size behaves like another.
Do 2021 McLaren tires require inner tubes?
The available 2021 McLaren fitments here are modern radial performance sizes, and their sidewall markings do not indicate tube-type construction. The 245/35R19, 305/30R20, and 225/35R20 offerings all appear as contemporary tubeless-style products, with no TT marking in the size. That matches what most buyers would expect in late-model 19-, 20-, and 21-inch McLaren applications.
Even so, wheel condition still matters. If a wheel has been repaired, refinished, or changed from original specification, verify that the wheel is suitable for tubeless service and that the valve stem and bead seats are in proper condition. On a 2021 McLaren, tire selection is only part of the setup; a high-performance tire also depends on a correctly prepared wheel to seal and perform as intended.
Maintenance, Storage & Longevity
How should I store a 2021 McLaren when the tires are fitted?
A 2021 McLaren should be stored on clean, properly inflated tires in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment. Low-profile radial tires hold their shape better than older bias-ply designs, but they still age from heat, UV exposure, and long static periods. Rolling the car slightly from time to time can help avoid one spot carrying the load continuously.
If the car sits for long stretches, many owners also use tire cradles or stands to reduce stress at the contact patch, especially on expensive staggered supercar fitments. Keep the storage surface clean and free of petroleum products that can migrate into the rubber. Before the next drive, bring pressures back to the proper setting and inspect every tire visually instead of assuming a climate-controlled garage has prevented all aging.
How long do tires on a 2021 McLaren typically last?
On a 2021 McLaren, tire age usually matters more than tread mileage because many of these cars see limited annual use. A sensible collector-car rule is to begin evaluating tires closely around five to seven years from the DOT date code and to treat roughly ten years as a point where replacement deserves serious consideration, even if tread remains. Heat cycles, storage conditions, and exposure to sun or ozone can shorten that timeline.
That approach is especially important on ultra-low-profile performance sizes, where the tire has a major role in steering response and high-speed stability. A lightly used set can still harden, crack, or lose confidence on the road as it ages. Check the date code on every tire, including the spare if one is present, and judge the set by age and condition rather than by remaining tread alone.
How often should tires on a 2021 McLaren be inspected?
Tires on a 2021 McLaren deserve a quick inspection before every drive and a more careful inspection before any longer outing. Look for pressure loss, cuts, bulges, shoulder wear, punctures, and any cracking in the sidewall or tread grooves. Because these cars use staggered fitments, it is also important to confirm that each tire remains in its correct front or rear position and that no mismatched size has been fitted on one axle.
A more thorough inspection every few months is also worthwhile, even if the car is not being driven often. Pay attention to wheel damage, embedded debris, and any vibration or steering change that might suggest an impact issue. Catching a problem early matters on a 2021 McLaren because the combination of low profile, wide rear tires, and very high performance leaves less room for neglect than on an ordinary touring car.
Safety & Road Use
Are 2021 McLaren tires safe for highway driving?
Yes, the available 2021 McLaren sizes are modern radial performance tires suitable for highway use when they are correctly sized, properly inflated, and in sound condition. The 245/35R19 and 225/35R20 options shown here carry W speed ratings, which correspond to 168 mph. In the 305/30R20 rear size, Nitto also carries a W rating, while the Pro-Trac versions do not show a speed letter in the sidewall size marking. Tire condition and proper application matter as much as the rating itself.
On a road-going McLaren, the tire is only one part of the safety picture. Suspension condition, alignment, brakes, and wheel condition all affect stability at normal highway speeds, and a supercar that has sat unused can need attention in all of those areas. Match the tire to the correct model and axle, confirm the sidewall marking on the exact product, and avoid using a speed rating as a substitute for a full pre-drive mechanical check.
What inflation pressure should I use for 2021 McLaren tires?
Inflation pressure on a 2021 McLaren should follow the vehicle’s factory recommendation first, because pressure is tied to the model, axle position, and intended loading. The available tire details here include one load-and-pressure reference in 245/35R19, where a BFGoodrich g-Force Phenom T/A is rated at 1,433 pounds at 50 psi. That figure is the tire’s rated load reference, not a blanket setting for every 2021 McLaren tire size.
Use the owner’s manual or the vehicle’s tire-information placard for the operating pressure McLaren intended, then compare that with the tire maker’s guidance for the exact product. Front and rear pressures often differ on staggered mid-engine cars, and one McLaren model should not borrow a pressure assumption from another. Recheck pressures when the tires are cold, especially after storage or seasonal temperature swings.
What should I check before taking a 2021 McLaren on a longer drive?
Before a longer drive in a 2021 McLaren, inspect each tire for cracking, punctures, sidewall bubbles, uneven wear, and signs of impact damage from potholes or curbs. Confirm cold inflation pressures, verify that front and rear sizes match the correct axle, and look closely at the valve stems and wheel lips. On cars with low-profile performance tires, even small wheel damage can affect sealing and ride quality.
A longer-trip inspection should also extend beyond the tires. Brake condition, fluid levels, battery health, and the operation of TPMS or warning systems all matter on a modern high-performance car that may spend time parked between uses. If the car has been stored, take a short test drive first and pay attention to vibration, pull, or steering change before committing to highway miles.
