2014 McLaren Tire Fitment Guide

2014 McLaren vehicles use four sizes across two models. The MP4-12C uses 235/35R19 in front and 305/30R20 in the rear, while the P1 uses 245/35R19 in front and 315/30R20 in the rear. Front sizes mount on 19-inch wheels and rear sizes mount on 20-inch wheels. Rim-width guidance appears on some 19-inch front tire products, with 235/35R19 and 245/35R19 examples covering roughly 8 to 9.5 inches.

That means fitment starts with model identification, then with confirming whether you are replacing a front or a rear tire. A 2014 McLaren does not use one universal size across the range, and the two cars do not share the same front or rear measurements. If your car already wears aftermarket wheels or nonstandard tires, compare the existing sidewall markings and actual wheel diameters before choosing a replacement.

On a 2014 McLaren, 235/35R19 is a modern metric radial size. The 235 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 2014 McLaren applications, that size is used as the front tire on the MP4-12C rather than across the full model range.

Reading the code correctly helps prevent one of the most common supercar ordering mistakes: matching width and profile but missing wheel diameter or model application. A 235/35R19 belongs with a 19-inch front wheel and should be treated as one half of the MP4-12C’s staggered setup. If you are replacing only one tire, confirm that the opposite side and the rear axle still match the same fitment plan.

No. The 2014 McLaren MP4-12C uses 235/35R19 front and 305/30R20 rear, while the 2014 McLaren P1 uses 245/35R19 front and 315/30R20 rear. Both models follow the same 19-inch front and 20-inch rear wheel-diameter pattern, but the actual tire widths differ at both ends. Every size in the range is model-specific rather than shared across all 2014 McLaren vehicles.

That distinction matters because a tire that looks close on paper can still be the wrong choice for the car’s intended wheel and axle position. The safest starting point is the exact model name on the car, then the axle location, then the size molded into the current tire sidewall. Treat year and make as the beginning of the search, not the final fitment answer.

2014 McLaren front sizes appear in Blackwall form, while the rear sizes broaden the visual options. The 305/30R20 and 315/30R20 are available in Blackwall as well as RWL and Redline versions, depending on series and brand. Blackwall is the most visually restrained choice and aligns most naturally with the modern supercar look McLaren used in this period.

Sidewall style is mostly an appearance decision once the correct size is established. Owners aiming for a contemporary, factory-like presentation usually stay with Blackwall, while RWL or Redline can push the car toward a more customized visual theme. Because sidewall style can vary by size, it is worth confirming that the front and rear appearance will complement each other before making a final selection.

2014 McLaren sizes are covered by Nitto, BFGoodrich, and Pro-Trac. The 235/35R19 front size for the MP4-12C is available from Nitto and BFGoodrich, the 245/35R19 front size for the P1 is available from BFGoodrich and Nitto, and both 20-inch rear sizes are available from Nitto and Pro-Trac. Across the range, all of these are radial applications aimed at modern high-performance fitments.

Brand choice comes after model and size are nailed down. Some buyers will prioritize a subdued Blackwall appearance, while others may want one of the rear-size visual treatments from Pro-Trac. It also helps to compare details such as speed rating, load figures where available, and wheel-width guidance on the specific size you need rather than choosing only by brand familiarity.

On 2014 McLaren front sizes where both appear, the Nitto NT555 G2 and BFGoodrich g-Force Phenom T/A are both radial Blackwall choices, but they differ in some published details. In 235/35R19, the Nitto carries a 91W marking and weighs 23.81 pounds, while the BFGoodrich carries a 91Y marking, weighs 24 pounds, supports up to 1,356 pounds at 50 psi, and fits rims from 8 to 9.5 inches. In 245/35R19, the BFGoodrich carries a 93W marking with up to 1,433 pounds at 50 psi and the same 8 to 9.5-inch rim range, while the Nitto carries a 93W XL marking.

That makes the comparison less about broad category differences and more about the exact published characteristics of the size you need. If rim-width compatibility and stated load capacity are central to your decision, the BFGoodrich entries provide those figures on these front sizes. If you are matching an existing setup, compare the full sidewall code and your wheel dimensions before choosing between the two.

Rim-width guidance is available on the two 19-inch front sizes used by 2014 McLaren vehicles. The 235/35R19 appears with a rim-width range of 8 to 9.5 inches, and the 245/35R19 also appears with a rim-width range of about 8 to 9.5 inches. The rear 20-inch sizes, 305/30R20 and 315/30R20, are tied to 20-inch wheel diameter, though published rim-width figures are not attached to every rear product.

Wheel diameter and wheel width both matter on low-profile performance tires, especially on cars as sensitive to setup as a modern McLaren. If your car still has its original wheels, the correct size pair is usually straightforward once the model is confirmed. If it wears aftermarket wheels, measure wheel width or verify the wheel specification before moving ahead with a tire choice.

The 2014 McLaren tire sizes here are modern radial performance sizes and do not carry tube-type markings. Their size markings use ZR-format radial nomenclature associated with contemporary tubeless performance applications rather than vintage tube-type construction. That aligns with the kind of wheel and tire system expected on 2014 McLaren supercars.

Even so, the practical check is always the tire sidewall marking and the wheel itself. A damaged wheel, a specialty application, or a nonstandard setup can change what is appropriate in service. If the car has aftermarket wheels or any unusual bead-seat treatment, verify tubeless suitability before mounting rather than assuming every 19- or 20-inch performance wheel is identical.

Original 2014 McLaren wheel compatibility follows model-specific diameter and axle position, not a one-size-fits-all rule. Both models use 19-inch front wheels and 20-inch rear wheels, but the MP4-12C uses 235/35R19 and 305/30R20, while the P1 uses 245/35R19 and 315/30R20. A front tire cannot simply move to the rear, and a P1 rear size should not be treated as interchangeable with an MP4-12C rear size just because both fit 20-inch wheels.

That means original wheels can be retained when you stay within the correct model’s front and rear size pair. Diameter compatibility is clear, but width compatibility should still be checked if the car has been modified, repaired with replacement wheels, or fitted with a different wheel package at some point. On modern exotics, even small deviations can affect clearance and overall setup.

A 2014 McLaren should be stored in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can accelerate rubber aging. Keep the tires properly inflated, avoid long-term contact with standing moisture, and move the car periodically if possible so one part of the tread is not carrying the load for months at a time. Radial tires tolerate storage better than older bias-ply designs, but they still age from time, heat, and environment.

On a low-mileage supercar, tire condition can decline long before the tread is worn out. If the car will sit for an extended season, many owners use flat-free storage practices such as occasional rolling or properly placed stands to reduce stress on the carcass. A brief inspection before the next drive should include sidewalls, tread faces, and air pressure rather than assuming an indoor-stored tire is automatically road-ready.

Tires on a 2014 McLaren are usually judged more by age than by mileage, especially on collector-owned or low-use examples. A sound rule is to begin regular age-based evaluation around five to seven years and to treat around ten years as a serious replacement point regardless of tread depth. The DOT date code on the tire sidewall is the key reference for age, not the model year of the car.

That matters because a supercar can spend long periods parked, heat-cycle its tires hard on short outings, and still appear to have plenty of tread left. Rubber hardening, fine sidewall cracking, and reduced wet-weather confidence can show up before obvious wear bars become the issue. If the car’s service history is unclear, checking the date code is one of the quickest ways to judge whether replacement deserves priority.

Tires on a 2014 McLaren should be checked before every drive and more thoroughly before any longer trip or spirited outing. Look for cuts, punctures, bubbles, curb damage, unusual shoulder wear, and any signs of cracking in the sidewall or tread grooves. Pressure retention also matters on low-profile high-performance tires, because a small loss can change the way the car feels and wears.

A visual glance is not enough on a car with staggered, low-profile tires and very high performance potential. Use a quality gauge, inspect the inside sidewall when possible, and include the spare or mobility equipment in your routine if the car is so equipped. Catching early wear or damage is especially important when the front and rear sizes are unique to the model and cannot simply be swapped around.

Yes, the 2014 McLaren sizes here are modern radial performance tires suited to highway use when they are in good condition, properly inflated, and matched to the correct model and axle. Speed ratings shown in these sizes include W and Y, with W rated up to 168 mph and Y rated up to 186 mph. Those ceilings exceed normal U.S. highway speeds by a wide margin, so real-world safety usually depends more on tire age, condition, inflation, and the car’s overall mechanical state than on the rating itself.

For a supercar, that means the question is less about whether the tire category is highway-capable and more about whether the specific tires on the car are healthy and correctly fitted. A ten-year-old tire with plenty of tread is still a concern, and a mismatched front or rear size can upset the balance McLaren engineered into the chassis. Confirm the exact sidewall code and inspect every tire before any sustained highway run.

Inflation pressure for a 2014 McLaren should start with the vehicle manufacturer’s recommendation for the exact model and axle position, because the MP4-12C and P1 use different front and rear sizes. Tire-specific figures also matter: the BFGoodrich 235/35R19 shows a maximum load of 1,356 pounds at 50 psi, and the BFGoodrich 245/35R19 shows 1,433 pounds at 50 psi. Those figures are tire ratings, not a blanket instruction to run every 2014 McLaren tire at 50 psi.

Use the factory placard or owner’s manual for the operating pressure target, then confirm that the chosen tire is appropriate for that application. Never transfer a pressure assumption from a 19-inch front tire to a 20-inch rear tire, or from an MP4-12C to a P1, just because the cars are from the same year and make. On staggered supercar fitments, pressure is part of the overall setup.

Before a longer drive in a 2014 McLaren, inspect each tire for cracking, punctures, cuts, bulges, uneven wear, and any evidence of impact damage from potholes or curbs. Check cold pressures, confirm that the front and rear sizes match the model, and look closely at the valve stems and bead area for leakage concerns. If the tires are several years old, include the DOT date code in your review rather than relying on tread depth alone.

A longer trip is also the right moment to think beyond the tires themselves. High-performance cars place heavy demands on alignment, braking, and suspension, and those systems influence tire wear and stability just as much as the rubber does. A quick pre-drive inspection can prevent a small issue, such as a slow leak or sidewall bruise, from turning into a much larger problem once the car is at speed.
