2026 McLaren Tire Fitment Guide

2026 McLaren vehicles use six model-specific tire sizes rather than one shared fitment. The 750S uses 245/35R19 front and 305/30R20 rear, the Artura uses 235/35R19 front and 295/35R20 rear, and the GTS uses 225/35R20 front and 295/30R21 rear. Rim width guidance appears for some sizes: 245/35R19 works with 8.0 to 9.5-inch rims, and 235/35R19 works with 8.0 to 9.5-inch rims.

That staggered layout means the first fitment question is always the exact model, followed by the correct front and rear wheel diameters. A 19-inch front on one 2026 McLaren does not automatically mean the same front tire works on another, and rear sizes change as well. If your car has aftermarket wheels, compare the tire size and wheel width against the actual wheel before choosing a replacement.

On a 2026 McLaren, 245/35R19 is a metric radial tire size. The 245 is the nominal section width in millimeters, 35 is the aspect ratio, R means radial construction, and 19 is the wheel diameter in inches. For 2026 McLaren fitment, that size is used on the front of the 750S and works with an 8.0 to 9.5-inch rim range on the products that publish rim-width guidance.

Reading the code correctly matters because a 245/35R19 is not interchangeable with the Artura’s 235/35R19 front tire, even though both mount on 19-inch wheels. The width and profile affect how the tire sits on the wheel and how closely it matches the intended front-to-rear balance. If you are replacing only one axle, verify the remaining axle still carries the proper companion size for your exact model.

No, 2026 McLaren models do not use the same tire sizes. Each model has its own front and rear pairing: the 750S uses 245/35R19 and 305/30R20, the Artura uses 235/35R19 and 295/35R20, and the GTS uses 225/35R20 and 295/30R21. Every size in the range is tied to a specific model rather than shared across the whole 2026 McLaren lineup.

That distinction is especially important on modern McLarens because wheel diameter, width, and overall stance are tightly integrated into the car’s setup. A buyer who knows only the year and make still needs to identify the model before moving on to brand or sidewall preferences. Once the model is confirmed, the correct front and rear sizes narrow the choices quickly.

Most 2026 McLaren tire sizes are offered in Blackwall form, which matches the contemporary appearance expected on modern supercars. The one size with visible sidewall variety is 305/30R20 for the 750S rear, where Blackwall, RWL, and Redline treatments are available. The remaining covered sizes center on Blackwall styling only.

For a modern McLaren, Blackwall is usually the most visually natural choice because it preserves the clean, technical look of the car. RWL or Redline sidewalls can change the appearance significantly and may appeal more to a custom direction than a factory-style presentation. If appearance matters as much as fitment, compare sidewall style before settling on a product in the correct size.

2026 McLaren tire coverage here comes from BFGoodrich, Nitto, and Pro-Trac. The 245/35R19 front size for the 750S is available from BFGoodrich and Nitto, the 305/30R20 rear size for the 750S comes from Nitto and Pro-Trac, the 235/35R19 front size for the Artura comes from BFGoodrich and Nitto, and the 295/35R20 and 225/35R20 sizes are represented by Nitto. All of those offerings are radial tires.

Brand choice becomes a second-step decision after confirming the exact model and front or rear size. Some sizes offer only one brand path, while others let you compare a more mainstream Blackwall performance tire against an option with a different sidewall look. That makes it worth deciding whether your priority is factory-style appearance, a particular brand family, or a specific speed-rating detail within the proper size.

For 2026 McLaren applications where both appear in the same size, BFGoodrich g-Force Phenom T/A and Nitto NT555 G2 differ in published load and speed details. In 235/35R19, the BFGoodrich version carries a Y rating to 186 mph and a maximum load of 1,356 pounds at 50 psi, while the Nitto version carries a W rating to 168 mph. In 245/35R19, both carry W-rated markings to 168 mph, and the BFGoodrich Phenom T/A publishes a maximum load of 1,433 pounds at 50 psi.

Those differences do not change the need to match the correct McLaren model and axle position first, but they can matter when comparing one tire’s published specs against another in the same size. A buyer deciding between the two should look at the exact size, speed symbol, and any available rim-width or load information instead of assuming every 19-inch front option is identical. That approach keeps the comparison factual and size-specific.

Rim-width guidance is published for some 2026 McLaren tire sizes. The 245/35R19 used on the 750S front fits an 8.0 to 9.5-inch rim range, and the 235/35R19 used on the Artura front fits an 8.0 to 9.5-inch rim range as well. The other covered sizes do not all publish rim-width details in the same way, so fitment confirmation should be made against the actual wheel being used.

Rim width matters because the same nominal tire size can behave differently if mounted on a wheel outside the intended range. That is especially relevant on low-profile McLaren fitments, where sidewall height is short and wheel-to-tire proportion is more sensitive than on a taller collector-car tire. If the car has replacement wheels, verify both diameter and width before moving forward.

The 2026 McLaren tires covered here are modern radial sizes with no tube-type markings in their size designations. They are treated as tubeless fitments rather than traditional tube-type applications. That aligns with the low-profile 19-, 20-, and 21-inch supercar tire formats used on the 750S, Artura, and GTS.

Even with tubeless tires, wheel condition and valve-stem condition still matter. A bent wheel, damaged bead seat, or aging valve stem can create air-loss issues that have nothing to do with the tire’s nominal size. During installation, it is wise to inspect the wheel carefully and confirm that the mounting hardware and valve components are appropriate for the car’s current wheel setup.

A 2026 McLaren should be stored away from direct sunlight, standing moisture, and ozone sources such as electric motors, battery chargers, welders, or compressors. Keep the tires clean, maintain proper inflation, and move the car periodically if it sits for long intervals. Modern radial tires resist temporary flat-spotting better than old bias-ply designs, but long static storage can still affect ride quality and pressure retention.

Because McLaren fitments use very short sidewalls, they benefit from extra attention during long dormant periods. If the car will be parked for months, many owners reduce stress on the contact patch by rolling the car occasionally or using stands in a manner consistent with the chassis maker’s lifting guidance. A clean, climate-stable garage does as much for tire life as it does for the rest of the car.

Tires on a 2026 McLaren should be judged by age and condition as much as by tread depth. A useful collector-car rule is to begin evaluating tires closely around five to seven years and to treat the ten-year point as a strong replacement consideration, even if mileage is low. The DOT date code on the sidewall helps establish the tire’s actual age.

That guideline matters on low-mileage exotics because a tire can age out long before it wears out. Heat cycles, storage conditions, and long periods of inactivity all influence rubber condition, especially on high-performance low-profile radials. If a 2026 McLaren still has older tires with ample tread, sidewall age and hardening can still justify replacement before the next major driving season.

Tires on a 2026 McLaren deserve a quick inspection before every drive and a more thorough check before any extended outing. Look for sidewall cuts, bulges, curb damage, punctures, uneven wear, and pressure loss, especially because low-profile tires can hide internal or bead-area damage after an impact. Include the spare or mobility equipment check if the car is equipped with one.

Frequent inspection is worthwhile because performance cars can be sensitive to even small changes in tire condition or inflation. An issue that feels minor at parking-lot speed can become far more noticeable once the car is loaded at highway pace. If one tire keeps losing pressure, inspect the valve stem and wheel as closely as the tire itself before assuming the casing is the only cause.

Yes, the 2026 McLaren tire sizes covered here are modern radial designs intended for contemporary road use. Published speed ratings include W at 168 mph and Y at 186 mph on certain sizes, while some 305/30R20 options do not show a speed letter in the size marking and should be reviewed product by product. In ordinary highway use, the car’s alignment, suspension condition, and tire age matter at least as much as the raw speed symbol.

For a buyer, the main takeaway is to match the exact McLaren model and axle size first, then confirm the speed rating of the specific tire chosen. Highway safety also depends on condition: proper inflation, no impact damage, even tread wear, and wheels that are true and undamaged. On a modern supercar, small setup issues can affect stability more quickly than on a softer, taller-tired car.

Inflation pressure on a 2026 McLaren should start with the factory vehicle recommendation for the exact model and tire size, then be checked against the tire maker’s own sidewall and load guidance. Published load-pressure information appears on some sizes, including 235/35R19 at 1,356 pounds at 50 psi and 245/35R19 at 1,433 pounds at 50 psi. Those figures are maximum load references for those specific tires, not a universal running pressure for every 2026 McLaren size.

That distinction matters because front and rear tires differ by model, and tire pressure should never be copied from one size to another just because the car carries the same badge. Use the door-jamb, manual, or manufacturer guidance for routine operating pressure, then confirm the tire’s own rating as a separate reference point. Accurate cold-pressure checks are especially important on low-profile tires where small changes are easier to feel.

Before a longer drive in a 2026 McLaren, inspect all four tires for cracks, punctures, cuts, bulges, and uneven wear, and verify cold pressures carefully. Pay extra attention to sidewalls and inner shoulders, since low-profile performance tires can suffer damage from potholes or curb strikes that is not obvious from a quick glance. Check the condition of the valve stems and confirm that each wheel is free of visible bends or rash near the bead area.

Tires are only one part of a proper pre-drive check on a high-performance McLaren. It also makes sense to look at brakes, fluid levels, suspension feel, and any warning messages before committing to a longer route. If the car has sat for a while, a short local drive can reveal vibration or pressure-loss concerns before you are far from home.
