The 2015 McLaren P1 sits at the leading edge of the modern hypercar era, blending advanced aerodynamics, hybrid performance, and track-focused engineering in a way that made tire fitment especially critical to the car’s balance. On this model, tire selection is a front-and-rear decision rather than a single-size choice, with 245/35R19 used up front and 315/30R20 at the rear, both in radial construction. That opens up practical differences in brand, tire series, and sidewall presentation, especially on the rear size where blackwall, redline, and raised white letter options appear. The key is matching the correct size to the correct axle while keeping wheel diameter, appearance, and intended road use in mind.
Which Tire Size Is Right for The 2015 McLaren P1
The 2015 McLaren P1 uses two primary tire sizes, with one dedicated to the front and the other to the rear. Both are radial metric sizes, but they use different rim diameters, so the first step is confirming whether you are replacing a front or rear tire and making sure the wheel diameter matches before comparing brands, series, or sidewall treatments.
The 245/35R19 size identifies a metric radial tire with a 245-millimeter nominal section width, a 35-series profile, and fitment on a 19-inch rim. On the 2015 McLaren P1, this is the front tire size, so its role is tied directly to steering response and front-end fitment. Available choices in this size include BFGoodrich and Nitto, with blackwall sidewalls and tire series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This size should be selected when replacing the front axle tires and after confirming the actual wheel setup on the car.
The 315/30R20 size is a wide metric radial, using a 315-millimeter nominal section width, a 30-series profile, and a 20-inch rim diameter. On the 2015 McLaren P1, this is the rear tire size, where width, wheel fitment, and overall stance matter just as much as tread choice. Available options include Nitto and Pro-Trac, with sidewall treatments that include blackwall, redline, and raised white letter in the Street Pro III and NT555 G2 series. This is the size to evaluate when replacing rear tires or refining the car’s visual presentation without changing the primary fitment.
Fitment on the 2015 McLaren P1 is straightforward once the axle position is identified. The front and rear are treated separately, so selecting the correct tire depends on matching the proper size to the proper wheel diameter at each end of the car.

2015 McLaren P1 Base Front
The 2015 McLaren P1 Base Front uses a dedicated radial front tire size on a 19-inch wheel. That makes front tire selection more about choosing among the available brands and tire series while keeping the correct front fitment and wheel setup intact.
The 2015 McLaren P1 Base Rear uses its own wider radial rear tire size on a 20-inch wheel. Rear tire selection is where sidewall style becomes more visible, so this is the area to compare appearance options along with the correct rear sizing.
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.
Best 2015 McLaren P1 Tires for Sale
Available 2015 McLaren P1 tire choices center on radial front and rear fitments from BFGoodrich, Nitto, and Pro-Trac. The product grid is where to compare tire series, blackwall versus redline or raised white letter styling on the rear size, and rim-width details where they are stated.
Tire questions for the 2015 McLaren P1 usually come down to front-versus-rear sizing, wheel diameter, product selection, and how appearance choices like blackwall, redline, or raised white letter affect the final look. The FAQs below focus on those exact fitment and ownership decisions.
Tire Size & Fitment
What tire size fits a 2015 McLaren P1?
The 2015 McLaren P1 uses two primary tire sizes rather than one all-around fitment. The front size is 245/35R19 and the rear size is 315/30R20, and both are radial tires.
That means tire replacement starts by confirming which axle needs tires, since the front and rear do not share the same size or rim diameter. A buyer should also confirm that the car still has its intended wheel setup, because aftermarket wheels or other changes can complicate an otherwise straightforward front-and-rear fitment.
What size rim does a 2015 McLaren P1 use?
The 2015 McLaren P1 uses two rim diameters. The front tire size mounts on a 19-inch rim, while the rear tire size mounts on a 20-inch rim.
Those diameters matter because tire selection for this car is tied directly to axle position as well as wheel size. Before choosing a replacement tire, check the actual wheel on the car and make sure the front and rear have not been changed, swapped, or replaced with a different diameter that alters the original staggered setup.
Why does the 2015 McLaren P1 have more than one tire size?
The 2015 McLaren P1 uses a staggered tire arrangement, with 245/35R19 at the front and 315/30R20 at the rear. The sizes are different because the front and rear of the car serve different roles in steering, traction, and overall chassis balance.
For the buyer, that means the correct tire is determined by location on the car, not simply by year, make, and model alone. Any replacement plan should preserve the front-and-rear distinction unless the vehicle has been intentionally reconfigured, and even then wheel diameter, width, and clearance need to be checked carefully before changing fitment.
Choosing the Right Tire
What should I consider when choosing tires for a 2015 McLaren P1?
Start with the correct axle-specific size: 245/35R19 for the front and 315/30R20 for the rear. From there, compare radial tire options by tire series, brand, sidewall style, and any stated rim-width or load details that apply to the size you are replacing.
The right choice depends on how the car is used and how closely you want to preserve its intended look. A front replacement may focus on matching the existing setup, while the rear size adds visible style choices such as blackwall, redline, or raised white letter, so appearance can become part of the decision as well.
What sidewall styles are available for 2015 McLaren P1 tires?
Sidewall style depends on the tire size and product chosen. The available front 245/35R19 options are blackwall, while the rear 315/30R20 size includes blackwall, redline, and RWL, which is a raised white letter sidewall treatment.
That makes the rear tire the more appearance-sensitive choice on this car. Buyers trying to maintain a subdued modern look may stay with blackwall, while those wanting a more custom or standout presentation may consider redline or raised white letters, provided the chosen tire still matches the correct rear size and wheel diameter.
What brands offer tires for the 2015 McLaren P1?
Tire options for the 2015 McLaren P1 include BFGoodrich, Nitto, and Pro-Trac, depending on the size. BFGoodrich and Nitto appear in the front 245/35R19 fitment, while Nitto and Pro-Trac are available in the rear 315/30R20 size.
Brand comparison should be done within the correct front or rear size rather than across the vehicle as a whole. It also helps to compare the tire series attached to each brand, since the available choices vary by axle and may carry different visual treatments or stated specifications even when the construction remains radial.
Restoration & Appearance
Which tire should I choose for a period-style 2015 McLaren P1?
A period-style approach on a 2015 McLaren P1 usually starts with keeping the correct staggered radial sizing in place: 245/35R19 front and 315/30R20 rear. That preserves the car’s modern performance-era stance while leaving room to choose among available tire series and sidewall presentations.
Appearance matters most when the rear tires are being selected, because that size includes blackwall, redline, and raised white letter options. Buyers aiming for a more restrained, contemporary presentation may lean toward blackwall, while a more customized visual statement points toward the other rear sidewall treatments without changing the basic fitment.
How does tire construction affect the appearance of a restored 2015 McLaren P1?
On the 2015 McLaren P1, the primary fitment is already radial, so construction choice is less about switching between eras and more about preserving the car’s intended modern presentation. The visible appearance difference comes more from tire series and sidewall treatment than from changing construction type.
That puts greater emphasis on matching the correct front and rear sizes and choosing a sidewall look that suits the car’s finish and overall theme. A blackwall rear tire keeps the visual tone cleaner, while redline or raised white letters create a more assertive look without altering the basic radial layout.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 McLaren P1?
Yes, modifications can affect tire fitment on a 2015 McLaren P1 even when the factory-style tire sizes are known. Changes to wheels, ride height, suspension components, or body clearance can alter whether a 245/35R19 front or 315/30R20 rear tire remains the right practical choice.
A car with aftermarket wheels should be checked for actual wheel diameter and width before replacement tires are chosen. Clearance at the fender, suspension, and steering range also matters, especially on a staggered setup, so modified cars deserve a careful measurement-based inspection rather than a simple size match.
What should I inspect before driving a 2015 McLaren P1 on new tires?
Before road use, inspect the tires for proper mounting, correct front and rear placement, visible damage, and stable air pressure. It also makes sense to check the wheels, valve stems, and tread surfaces so the new tires start service on sound hardware.
The rest of the inspection should include basic clearance checks and a close look at suspension and steering condition. A staggered high-performance setup depends on each tire being in the correct position, so confirming front 19-inch and rear 20-inch wheel locations before a drive is just as important as the condition of the tires themselves.
How often should tires on a 2015 McLaren P1 be inspected?
Tires on a 2015 McLaren P1 should be inspected regularly, especially before spirited driving, longer trips, or any period after the car has been stored. The inspection should cover tread condition, cuts, punctures, sidewall damage, and any signs of uneven wear or air loss.
Low-use collector cars can develop tire issues even when mileage stays low, so age and condition deserve as much attention as tread depth. A good routine is to check pressures and visible condition frequently, then take a closer look anytime the car has sat for an extended period or the wheel and suspension setup has changed.
