Kumho Ecowing ES01 KH27 vs ES31 - Which To Buy? [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 Ecowing ES01 KH27 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 Ecowing ES31 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 Ecowing ES01 KH27 and Ecowing ES31 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 Ecowing ES01 KH27 tyres rank a C on a scale of A to E in the official fuel tests carried out by the EU.

The Ecowing ES31 tyres, on the other hand, get a grade of B.

Expect the lower graded tyres to require about an extra 1 metres to come to a complete stop when braking at 80km/h.

Here's a graph comparing the Ecowing ES01 KH27 and Ecowing ES31 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 Ecowing ES01 KH27 tyres produce 70.0 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 Ecowing ES31 tyres produce 70.0 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 Ecowing ES01 KH27 and Ecowing ES31 tyres stack up for noise (1 = Grade C, 3 = Grade A).

Based on the results of a number of tyre benchmarks, the Ecowing ES01 KH27 scores 4 out of 5 for comfort and the Ecowing ES31 scores 4 out of 5.

As per the UTQG guidelines, the Ecowing ES01 KH27 tyres have a treadwear rating of 420, whereas the Ecowing ES31 tyres have a rating of 400. This means that the Ecowing ES01 KH27 tyres will theoretically last 1.1 times as long as the Ecowing ES31 tyres.

As per the, the Ecowing ES01 KH27 and Ecowing ES31 tyres both have a traction grading of A.

As per the UTQG system of tyre grading, the Ecowing ES01 KH27 and Ecowing ES31 tyres both have a temperature resistance grading of A.

For fuel efficiency, Ecowing ES01 KH27 score a grade of C, which is more or less average. Ecowing ES31 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, Ecowing ES01 KH27 get a score of C, which is more or less average. Ecowing ES31 end up with a grade of B, which is above average.

More important is the wet grip, which gives you an indication of their traction and handling. In this regard, Ecowing ES01 KH27 get a score of B, which is about typical. Ecowing ES31 end up with a grade of B, which is about typical.
