McLaren P1 Tires

McLaren P1 uses two tire sizes for both 2014 and 2015: 245/35R19 at the front and 315/30R20 at the rear. The front size mounts on a 19-inch rim, while the rear size mounts on a 20-inch rim. All listed McLaren P1 products in these sizes are radial tires, which matches the modern high-performance nature of the car.

The practical point is that year alone does not tell the full story, because the car uses a staggered setup with different sizes and wheel diameters at each axle. Start by identifying whether you are replacing front tires, rear tires, or a complete set, then confirm the wheel diameter on the car before matching the tire size. Keeping the correct front-to-rear relationship is important on a hypercar with this level of chassis and aero sensitivity.

On McLaren P1, 245/35R19 breaks down into four parts: 245 is the section width in millimeters, 35 is the aspect ratio, R means radial construction, and 19 is the rim diameter in inches. That makes it a modern low-profile front fitment rather than an older numeric or alphanumeric collector-car size. The listed products in this size are blackwall radials intended for 19-inch wheels.

Understanding that code helps prevent one of the most common mistakes on staggered exotic fitments: matching the width but missing the wheel diameter or axle position. If you are standing beside the car, verify that the tire being replaced is on the front axle and that the wheel itself is 19 inches before choosing among the available options. Width, profile, and rim diameter all need to stay in balance on McLaren P1.

McLaren P1 uses two rim diameters rather than one: 19-inch rims at the front and 20-inch rims at the rear, and that arrangement applies across the 2014 and 2015 model years. The front tire size is 245/35R19 and the rear tire size is 315/30R20. There is no year-to-year wheel diameter change in the listed range, but there is a permanent front-to-rear split.

That means the key check is axle position, not just model year. A buyer replacing only one pair should verify whether the tires needed are front or rear before comparing products, because a 19-inch front tire will not interchange with a 20-inch rear wheel. If the car has aftermarket wheels, measure and confirm the wheel diameter directly before selecting a replacement tire.

For both 2014 and 2015, McLaren P1 uses 245/35R19 on the front axle and 315/30R20 on the rear axle. The year range does not change the size pairing, so the main fitment step is identifying which axle you are servicing. Front and rear tires also use different wheel diameters, with 19 inches up front and 20 inches at the rear.

The easiest way to confirm the correct choice is to inspect the tire sidewall already on the car and compare it to the wheel position. If the existing tires are not original to the car or the wheels have been changed, verify the wheel diameter directly and compare overall setup side to side before replacing anything. On a car like McLaren P1, replacing by axle pair rather than one tire at a time is often the cleaner fitment approach.

McLaren P1 tire options in the listed range include Blackwall, Redline, and RWL sidewall styles. Blackwall appears in both the 245/35R19 front size and the 315/30R20 rear size, while Redline and RWL appear in the 315/30R20 rear size. That gives buyers a standard modern performance look as well as more appearance-driven alternatives at the rear.

For a factory-like modern hypercar appearance, blackwall is the most restrained visual choice and the easiest way to keep the car’s look contemporary. Redline or raised white letter styling changes the presentation noticeably and may suit a personalized build more than a stock-style presentation. If appearance matters as much as fitment, compare the front and rear sidewall look together so the full stance feels intentional.

The listed McLaren P1 tire options come from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in the 245/35R19 front size, Nitto appears in both front and rear sizes, and Pro-Trac appears in the 315/30R20 rear size. All of the products listed for McLaren P1 are radial tires.

Brand choice on McLaren P1 is less about finding a single universal option and more about matching the correct size, axle position, and visual style. If you want the same brand front and rear, Nitto is the listed brand that spans both sizes. If you are mixing brands by axle, keep the tire sizes and intended front-to-rear setup correct first, then compare sidewall style and overall appearance.

McLaren P1 tire options in the listed range include the BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III series. All are radial tires, but they represent different product families and visual presentations within modern performance sizing. Street Pro III also appears with multiple sidewall styles in the 315/30R20 rear size.

For the buyer, series selection comes after the fitment basics are settled. Start by separating front 245/35R19 needs from rear 315/30R20 needs, then compare series by brand continuity, sidewall appearance, and the way you intend to use the car. A McLaren P1 kept mostly for display, occasional driving, or a more personalized look may point you toward a different series choice than a car kept visually close to a standard modern blackwall presentation.

McLaren P1 should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, ozone sources, and long exposure to heat. Tire pressures should be checked regularly during storage, because a low-profile staggered setup can develop flat spotting or sidewall stress if the car sits underinflated for long periods. Clean tires and wheels before storage so road debris and chemical residue do not remain on the rubber.

If the car will sit for an extended period, move it periodically or use appropriate storage supports to reduce one-point loading. A modern hypercar with 19-inch front and 20-inch rear tires benefits from careful storage discipline because the tires are a structural part of the car’s overall feel. Keeping the car on a stable surface and avoiding months of static weight in one position helps preserve ride quality when it returns to service.

Tires on a McLaren P1 should be visually inspected before each drive and more thoroughly at regular service intervals, even if the car covers very low annual mileage. Check for cracking, bulges, punctures, uneven wear, sidewall damage, and any sign that the front and rear tires are aging differently. Pressure condition matters just as much as visible wear on a high-performance radial setup like this one.

A collector-owned McLaren P1 often spends more time parked than driven, which makes aging and storage-related changes easy to miss. Pay special attention after the car has sat for weeks or months, and inspect the inner sidewalls as well as the outer visible face. Because the front and rear tires are different sizes and loads, comparing wear patterns axle to axle can also reveal alignment or suspension issues early.

McLaren P1 tires should be replaced when age, hardening, cracking, impact damage, or structural deterioration appears, even if tread depth still looks acceptable. Collector cars and low-mileage exotics can age out their tires before they wear them out, especially when they spend long periods parked. Any tire that shows visible weathering, deformation, or repeated pressure loss deserves immediate evaluation.

The practical rule is to judge McLaren P1 tires by condition and service life, not tread alone. A hypercar can place heavy demands on rubber that appears lightly used, so an old tire may no longer behave like a fresh one under braking, acceleration, or cornering. Checking date codes and having the tires assessed during routine service is a sensible part of preserving both the car’s performance and its road manners.

The listed McLaren P1 tire options are modern radial tires in the correct front and rear sizes, which makes them appropriate starting-point fitments for public-road use when they are mounted correctly, in good condition, and matched to the proper wheel diameters. McLaren P1 uses 245/35R19 in front and 315/30R20 in the rear, so basic safety begins with preserving that staggered arrangement. Tire age, condition, and proper inflation remain just as important as size.

Safe road use depends on the complete condition of the car, not only the sidewall size. Before driving, confirm that the tires are free of damage, pressures are correct, and the front-to-rear setup has not been mixed up during replacement. On a car with McLaren P1 performance levels, a small fitment mistake can have a much larger effect than it would on an ordinary passenger car.

Before driving a McLaren P1, check tire pressure, visible condition, tread surface, and any sign of cuts, punctures, or sidewall damage. Confirm that 245/35R19 tires are fitted to the front axle and 315/30R20 tires are fitted to the rear axle, and make sure the wheel diameters match those sizes. A quick walkaround should also look for uneven ride height or a tire that appears lower than the others.

That pre-drive habit matters especially on a low-use exotic, where a car may sit long enough for pressures to drift or for age-related issues to become visible only when the car is about to move. If anything looks unusual, inspect more closely before rolling the car out. Hypercar performance leaves little margin for neglect, so a two-minute check can prevent a much larger problem on the road.

A McLaren P1 should only be driven at speeds appropriate to the condition, age, and specification of the tires currently fitted, not to the car’s theoretical capability. The listed McLaren P1 options are modern radial products, but even a correctly sized tire cannot be assumed to perform like a new tire if it is aged, damaged, or improperly stored. Tire condition always governs safe speed more than the badge on the car.

For practical use, treat any newly acquired McLaren P1 conservatively until tire age, inflation, and overall condition have been checked. Smooth inputs and gradual speed buildup are wise any time tire history is uncertain. A car of this caliber can exceed the comfort zone of compromised rubber very quickly, so the responsible approach is to let the condition of the tires set the pace.
