Kumho Ecsta HS51 vs Kumho Ecsta PS71 in Australia

The Ecsta HS51 has been around in Australia for about 9 years, whereas the Ecsta PS71 has been on the market for about 8 years

Both tyres are rated for ultra high performance summer action. 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. Both brands are considered to be in the mid-range part of the market.

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 156 sizes of these tyres by the European Union.

Fuel Efficiency

EU Grade
(A - E)
Compared to an A grade tyre?
Ecsta HS51D0.3L/100km extra fuel consumption. ~$61 extra per year
Ecsta PS71D0.3L/100km extra fuel consumption. ~$64 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 HS51 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 Ecsta PS71 tyres get a grade of D

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

Here's a graph comparing the Ecsta HS51 and Ecsta PS71 tyres for fuel efficiency (1 = Grade E, 5 = Grade A).

Grip & Handling

EU Grade
(A - E)
Compared to an A grade tyre?
Ecsta HS51B2.5 metre greater stopping distance when braking at 80km/h
Ecsta PS71AThis 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 HS51 tyres rank a B on a scale of A to E in the official fuel tests carried out by the EU.

The Ecsta PS71 tyres, on the other hand, get a grade of A.

Expect the lower graded tyres to require about an extra 2 metres to come to a complete stop when braking at 80km/h.

Here's a graph comparing the Ecsta HS51 and Ecsta PS71 tyres for wet grip (1 = Grade E, 5 = Grade A).

Noise

EU Grade
(A - C)
Compared to an A grade tyre?
Ecsta HS51B (69.7 dB)2 times as noisy
Ecsta PS71B (71.8 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 HS51 tyres produce 69.7 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 Ecsta PS71 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 Ecsta HS51 and Ecsta PS71 tyres stack up for noise (1 = Grade C, 3 = Grade A).

Comfort

Based on the results of a number of tyre benchmarks, the Ecsta HS51 scores 5 out of 5 for comfort and the Ecsta PS71 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

The Ecsta HS51 tyres have a treadwear rating of 320, which means that they would last 3.2 times longer than a tyre with a rating of 100. There's no treadwear data available for the Ecsta HS51 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.

The Ecsta PS71 tyres have a traction grade of AA (on a scale of AA, A, B, C). There's no UTQG traction grading data available for the Ecsta HS51 tyres.

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.

The Ecsta PS71 tyres have a temperature resistance grade of A (on a scale of A, B, C). There's no UTQG temperature resistance grading data available for the Ecsta HS51 tyres.

Warranty

Unfortunately, we don't have any warranty information available for either of these tyres.
