Mobile Porsche Tyre Fitting in London, Matched to Your N-Rating

Reading N0, N1 and N2 before you order

Porsche says that only N-marked tyres are tested and approved by Porsche for their performance, handling and safety characteristics. The number after the N is not a quality grade. N0 is the first approved version of a particular tyre for that application, and higher numbers are later revisions of it. When the tyre maker launches a new model, the numbering starts again from zero, so an N0 on one tyre and an N2 on another tells you nothing about which is better.

The practical rule is simple: keep the same brand, the same tyre model and the same N-code across an axle, and ideally on all four wheels. Mixing an N1 and an N2 on the same axle puts two slightly different tyres side by side, and that shows up in how the car behaves at the limit. On four-wheel-drive models such as the Carrera 4, Cayenne, Macan and Taycan, a matched set on all four corners matters even more. When you ring us, read out the full sidewall of an existing tyre, or send a photo on WhatsApp, and we will match it.

Staggered sizes on the 911 and 718

The 911, Boxster and Cayman run staggered set-ups, with narrower tyres at the front and wider ones at the rear. That means you cannot move tyres from front to rear to even out wear. Rear tyres on these cars usually wear faster, so most owners end up replacing the rear pair on its own.

That is where generations catch people out. If your fronts are N0 and that version has since been replaced by N1, a new rear pair may come in a different generation from the fronts. With plenty of tread left on the fronts, keeping the same brand and model with a generation split front to rear is a reasonable short-term compromise. If the fronts are half worn, four new tyres on one code is usually the better answer, and we will tell you honestly which situation you are in.

Taycan, Cayenne and Macan: weight, noise and suspension

The Taycan was the first car to use Pirelli’s Elect-marked tyres, developed for electric cars with low rolling resistance to help range and reduced road noise. On the Taycan these carry an Elect marking alongside the Porsche N-code. Swapping to a non-Elect tyre will usually cost you some range and make the cabin noisier, so we recommend sticking with what the car was built around.

The Cayenne and Panamera are heavy cars, and many have air suspension. Some air-suspension Porsches need the self-levelling switched off, often called jack mode, before a wheel comes off the car. If yours has it, we will talk you through it or set it before we lift the car, so the suspension does not try to correct itself while the car is on the jack.

What a typical Porsche call-out looks like

Most of the Porsche calls we take in London fall into a handful of situations:

• A screw or nail in a low-profile rear tyre, found when the pressure warning comes on
• Kerbed or cut sidewalls on 20 and 21 inch wheels after tight parking
• Rear tyres worn to the limit on a 911 or Cayman ahead of an MOT or a trip
• A lost locking wheel bolt key when a tyre needs to come off
• A Taycan or Cayenne owner wanting the correct N-coded replacement rather than whatever is in stock nearby

Porsches use wheel bolts rather than nuts, and many have one locking bolt per wheel. If the key is missing, our locking wheel nut removal service handles the bolt versions too. Some GT and Turbo models use centre-lock wheels, which need a specific socket and a very high tightening torque, so mention this when you call and we will confirm what is needed before we set off.

Once the tyre is agreed, we drive to you, typically within 30 to 40 minutes across London. We lift the car at the correct points, protect the alloy during fitting, balance the wheel and set the pressures to the figures on your door pillar or fuel flap. Puncture repairs are only carried out where the damage is in the repairable area of the tread and the tyre has not been driven on flat, and we will show you the damage either way.
