Kumho Ecsta PS91 vs Michelin Pilot Sport 4 in Australia

The Ecsta PS91 has been around in Australia for about 11 years, whereas the Pilot Sport 4 has been on the market for about 9 years

The Ecsta PS91 is rated for extreme performance summer action, however the Pilot Sport 4 tyres are classified as max performance summer. Both tyres are designed for use with regular passenger (non-SUV) vehicles.

Both of these are considered summer tyres. Neither of them are runflat tyres. Kumho is considered to be a mid-range brand in the tyre market, whereas Michelin is a premium manufacturer.

Read on to see how each of these tyres stack up against each other!

How We Reviewed These Tyres

Unlike the Australian government, the European Union carries out standardised tests on all tyres sold in Europe. These tests are carried out in identical conditions, making them a reliable way to compare tyres.

For this review, we use averaged results from tests done on 214 sizes of these tyres by the European Union.

Fuel Efficiency

EU Grade
(A - E)
Compared to an A grade tyre?
Ecsta PS91D0.3L/100km extra fuel consumption. ~$72 extra per year
Pilot Sport 4C0.2L/100km extra fuel consumption. ~$52 extra per year

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 Ecsta PS91 tyres rank a D 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 4 tyres get a grade of C

Expect the lower grade tyre to consume an extra 0.1L/100km. This works out to $20 extra spent on petrol per year, based on a typical 12,000 km driven per year.

Here's a graph comparing the Ecsta PS91 and Pilot Sport 4 tyres for fuel efficiency (1 = Grade E, 5 = Grade A).

Grip & Handling

EU Grade
(A - E)
Compared to an A grade tyre?
Ecsta PS91AThis is an A grade tyre for wet grip
Pilot Sport 4AThis is an A grade tyre for wet grip

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 Ecsta PS91 tyres rank a A on a scale of A to E in the official fuel tests carried out by the EU.

The Pilot Sport 4 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 Ecsta PS91 and Pilot Sport 4 tyres for wet grip (1 = Grade E, 5 = Grade A).

Noise

EU Grade
(A - C)
Compared to an A grade tyre?
Ecsta PS91B (72.2 dB)2 times as noisy
Pilot Sport 4B (71.0 dB)2 times as noisy

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 Ecsta PS91 tyres produce 72.2 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 4 tyres produce 71.0 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 Ecsta PS91 and Pilot Sport 4 tyres stack up for noise (1 = Grade C, 3 = Grade A).

Comfort

Based on the results of a number of tyre benchmarks, the Ecsta PS91 scores 4 out of 5 for comfort and the Pilot Sport 4 scores 4 out of 5.

UTQG Data

Introduced by the National Highway Traffic Safety Administration (NHTSA) in the USA, the Uniform Tire Grading System (UTQG), is a system for comparing one tyre product to another on the basis of some standardised tests.

Treadwear

As per the UTQG guidelines, the Ecsta PS91 tyres have a treadwear rating of 260, whereas the Pilot Sport 4 tyres have a rating of 320. This means that the Ecsta PS91 tyres will theoretically last only 81% as long as the Pilot Sport 4 tyres.

Traction

The UTQG system measures traction as straight-line braking in dry conditions. The scale is AA, A, B, C, with AA being the best grade, and C the worst.

As per the UTQG system, the Ecsta PS91 tyres have a traction grading of AA, whereas the Pilot Sport 4 tyres have a grading of AA.

Temperature Resistance

The UTQG temperature resistance tests measure how well tyres can dissipate heat that builds up due to friction with the road. The scale is A, B, C, with A being the highest grade.

As per the UTQG system of tyre grading, the Ecsta PS91 tyres have a temperature resistance grading of A, whereas the Pilot Sport 4 tyres have a grading of A (on a scale of A, B, C).

Warranty

The Pilot Sport 4 tyres have a warranty of 6 years. There is no time-based warranty available for the Ecsta PS91.
