Michelin Pilot Sport 4 vs 4S (PS4/PS4S) - Test Data [2024]

Fuel Efficiency

The US Department of Energy estimates that around 25% of the fuel consumption of a vehicle is attributable to the tyres. That's a lot, and it means that choosing fuel efficient tyres can save you quite a bit of money.

The Pilot Sport 4 tyres rank a C on a scale of A to E in the official fuel efficiency tests carried out by the EU (they call these rolling resistance tests).

The Pilot Sport 4S tyres also get a grade of C.

As their fuel efficiency grade is the same, expect negligible differences in fuel consumption between them.

Here's a graph comparing the Pilot Sport 4 and Pilot Sport 4S tyres for fuel efficiency (1 = Grade E, 5 = Grade A).

Grip & Handling

We'll now take a look at how these tyres compare in terms of grip and handling.

A good measure of this is 'wet grip', which is an indication of how well the tyres will allow the vehicle to come to a stop in wet conditions.

The Pilot Sport 4 tyres rank a A on a scale of A to E in the official fuel tests carried out by the EU.

The Pilot Sport 4S tyres, on the other hand, get a grade of A.

As their wet grip grade is the same, expect negligible differences in terms of braking distance.

Here's a graph comparing the Pilot Sport 4 and Pilot Sport 4S tyres for wet grip (1 = Grade E, 5 = Grade A).

Noise

Another key factor to consider when choosing a tyre is road noise. Once you're over about 40 km/h, the dominant source of noise you hear is from the contact of your tyres on the road.

There is a surprisingly wide variation in the amount of noise each tyre makes.

The Pilot Sport 4 tyres produce 71.0 dB of road noise, which corresponds to a rank of B on a scale of A to C in the standardised testing done by the EU.

On the other hand, the Pilot Sport 4S tyres produce 71.8 dB of road noise, which means a grade of B.

As their noise grade is the same, don't expect many differences in terms of cabin noise.

Here's a visual representation of how the Pilot Sport 4 and Pilot Sport 4S tyres stack up for noise (1 = Grade C, 3 = Grade A).

Based on the results of a number of tyre benchmarks, the Pilot Sport 4 scores 3 out of 5 for comfort and the Pilot Sport 4S scores 5 out of 5.

As per the UTQG guidelines, the Pilot Sport 4 tyres have a treadwear rating of 320, whereas the Pilot Sport 4S tyres have a rating of 300. This means that the Pilot Sport 4 tyres will theoretically last 1.1 times as long as the Pilot Sport 4S tyres.

As per the, the Pilot Sport 4 and Pilot Sport 4S tyres both have a traction grading of AA.

As per the UTQG system of tyre grading, the Pilot Sport 4 and Pilot Sport 4S tyres both have a temperature resistance grading of A.

For fuel efficiency, Pilot Sport 4 score a grade of C, which is more or less average. Pilot Sport 4S end up with a grade of C, which is more or less average.

More important is the wet grip, which gives you an indication of their traction and handling. In this regard, both the Pilot Sport 4 and the Pilot Sport 4S get a score of A, which is outstanding.

More important is the wet grip, which gives you an indication of their traction and handling. In this regard, Pilot Sport 4 get a score of B, which is about typical. Pilot Sport 4S end up with a grade of B, which is about typical.
