The 2014 McLaren P1 sits at the leading edge of the modern hypercar era, blending advanced aerodynamics, hybrid performance, and extreme road-car engineering in a way that quickly made it a benchmark for collectors and serious drivers alike. Tire fitment on a car with this level of capability is especially configuration-specific, with a 245/35R19 radial up front and a 315/30R20 radial in the rear. That staggered setup means the real choice is not between multiple primary fitments, but between the available radial tire options within each position, including differences in brand, series, and sidewall presentation. Wheel diameter, front-versus-rear placement, and overall setup should be confirmed before any replacement.
Which Tire Size Is Right for The 2014 McLaren P1
The 2014 McLaren P1 uses two primary tire sizes, with one dedicated front fitment and one dedicated rear fitment. The front tire is a 245/35R19 radial on a 19-inch rim, while the rear tire is a 315/30R20 radial on a 20-inch rim. The first step is confirming whether you are replacing a front or rear tire, since rim diameter and tire size differ by axle.
245/35R19 is a modern metric radial size in which 245 identifies the nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2014 McLaren P1, this is the front tire size, so it must be matched to the correct front wheel position rather than treated as a universal all-around fitment. Available options in this size include BFGoodrich and Nitto products, all in blackwall form, across series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. Choosing within this size comes down to matching the proper front fitment while comparing brand, series character, and wheel-width compatibility.
315/30R20 is a modern metric radial size where 315 represents the nominal section width in millimeters, 30 is the aspect ratio, R marks radial construction, and 20 identifies the rim diameter in inches. On the 2014 McLaren P1, this is the rear tire size, making axle position and wheel diameter central to correct selection. Available choices include Nitto and Pro-Trac offerings, with sidewall treatments that include blackwall, redline, and raised white letter styles in addition to differences in tire series. This size should be evaluated as a rear-specific fitment, especially on a staggered setup where appearance and wheel match both matter.
The covered sub-model fitment is straightforward, but it is split by front and rear position rather than by trim variation. Checking the exact axle matters because the P1 uses different tire sizes and different rim diameters at each end of the car.

2014 McLaren P1 Base Front
The 2014 McLaren P1 Base Front uses the 245/35R19 radial tire size. Front tire selection should focus on maintaining the proper 19-inch fitment while comparing available brands and tire series suited to the P1's front axle position.
The 2014 McLaren P1 Base Rear uses the 315/30R20 radial tire size. Rear tire selection should center on the 20-inch wheel fitment and the available sidewall and series choices, since the rear setup differs substantially from the front.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2014 McLaren P1?
The 2014 McLaren P1 uses a staggered radial tire setup with 245/35R19 at the front and 315/30R20 at the rear. Those are two different primary sizes, and they are tied to two different wheel diameters, so they are position-specific rather than interchangeable across the car.
The important next step is confirming whether the tire being replaced is on the front or rear axle. A P1 with changed wheels or prior tire substitutions should also be checked carefully, since the car's front 19-inch and rear 20-inch arrangement is a major part of correct fitment.
What size rim does a 2014 McLaren P1 use?
A 2014 McLaren P1 uses two rim diameters as part of its staggered setup: 19-inch wheels at the front and 20-inch wheels at the rear. The front 245/35R19 tire is matched to the 19-inch front wheel, while the rear 315/30R20 tire is matched to the 20-inch rear wheel.
That means rim diameter must be verified before choosing a replacement tire, especially if the car has had wheel changes. Tire size alone is not enough on a front-to-rear staggered setup, and wheel width should also be checked against the tire being considered.
Why does the 2014 McLaren P1 have more than one tire size?
The 2014 McLaren P1 uses more than one tire size because its fitment is split between the front and rear of the car. The front uses 245/35R19 and the rear uses 315/30R20, so the size difference is part of the vehicle's staggered performance-oriented wheel and tire arrangement.
For replacement purposes, that makes position the first decision rather than brand or sidewall style. A buyer should confirm which axle needs the tire, then verify wheel diameter, wheel width, and any changes from stock before selecting among the available radial options.
Choosing the Right Tire
What should I consider when choosing a 245/35R19 or 315/30R20 tire for a 2014 McLaren P1?
Start with the correct axle-specific size, since the 2014 McLaren P1 uses 245/35R19 in front and 315/30R20 in the rear. After size and wheel diameter are confirmed, compare the available radial choices by tire series, sidewall style where applicable, and any stated wheel-width or load details.
The front and rear should not be treated as interchangeable just because both are modern radial sizes. Wheel width, intended use, and the overall condition of the car's suspension and alignment are worth checking so the selected tire suits the position where it will actually be used.
What sidewall styles are available for 2014 McLaren P1 tires?
Sidewall style depends on the tire size being replaced. In the 245/35R19 front size, the available products are blackwall, while the 315/30R20 rear size includes blackwall, redline, and raised white letter options. That means appearance choice is broader at the rear than at the front.
A buyer deciding on sidewall presentation should still begin with the correct front or rear size before focusing on looks. On a car like the P1, appearance, wheel fitment, and the tire series itself all need to be considered together rather than choosing by sidewall style alone.
What brands offer tires for the 2014 McLaren P1?
Available tires for the 2014 McLaren P1 come from BFGoodrich, Nitto, and Pro-Trac, depending on the size and position. The 245/35R19 front size includes BFGoodrich and Nitto options, while the 315/30R20 rear size includes Nitto and Pro-Trac choices across more than one sidewall treatment.
Brand should be considered alongside the exact size, axle position, and tire series rather than by itself. The most useful comparison is how each available tire matches the front or rear wheel setup, the desired appearance, and any stated wheel-width or load specifications.
Restoration & Appearance
Which tire should I choose for a period-style 2014 McLaren P1?
A period-style approach for a 2014 McLaren P1 starts with preserving the proper staggered fitment: 245/35R19 in front and 315/30R20 in the rear. From there, the most relevant appearance decisions come from tire series and sidewall treatment, especially in the rear size where blackwall, redline, and raised white letter options are available.
Because the P1 is a modern collector car, visual presentation can matter almost as much as fitment. Buyers pursuing a highly specific presentation should compare the available sidewall styles carefully and confirm that any chosen tire still matches the wheel setup and intended road use.
How does tire construction affect the appearance of a restored 2014 McLaren P1?
On the 2014 McLaren P1, the primary fitment is already radial, so the appearance question is less about switching construction and more about choosing the right modern radial presentation. In practice, that means the visible difference comes more from sidewall styling and tire series than from bias-ply-versus-radial considerations.
That keeps the focus on selecting a tire that suits the car's visual character without disturbing the correct front and rear sizing. A restoration-minded owner should verify the exact wheel setup first, then compare blackwall, redline, or raised white letter options where they are offered.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 McLaren P1?
Yes. Any wheel, suspension, alignment, or ride-height change can affect tire fitment on a 2014 McLaren P1, especially because the car uses different front and rear sizes with different rim diameters. Even when the tire size remains 245/35R19 front and 315/30R20 rear, the actual clearance situation can change.
A modified car should be checked for wheel width, offset, steering clearance, and fender or suspension clearance before replacement tires are chosen. That is particularly important on a low, high-performance vehicle where small setup changes can matter more than they would on a conventional street car.
What should I inspect before driving a 2014 McLaren P1 on new tires?
Before driving a 2014 McLaren P1 on new tires, inspect the wheel and tire sizes front and rear, confirm proper inflation, and look over each tire for shipping damage, bead seating issues, cuts, or visible defects. It is also wise to verify that the front 19-inch and rear 20-inch tires were mounted in the correct positions.
A short initial check of steering response, vibration, and clearance can help catch fitment or installation issues early. On a collector-grade performance car, alignment condition, suspension health, and proper torque on the wheels are all worth confirming before regular road use.
How should tires on a collector 2014 McLaren P1 be maintained?
Tires on a collector 2014 McLaren P1 should be maintained with regular pressure checks, routine visual inspection, and attention to age even if tread wear is low. Cars that spend long periods parked can still develop problems such as sidewall cracking, flat spotting, air loss, or other age-related deterioration.
Storage conditions matter on a low-use hypercar. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve tire condition, and each front and rear tire should be inspected before driving if the car has been sitting for an extended period.
