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 86 sizes of these tyres by the European Union.

Fuel Efficiency

EU Grade
(A - E)
Compared to an A grade tyre?
Discoverer AT3 XLTE0.4L/100km extra fuel consumption. ~$96 extra per year
All-Terrain T/A KO2E0.4L/100km extra fuel consumption. ~$96 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 Discoverer AT3 XLT tyres rank a E 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 All-Terrain T/A KO2 tyres get a grade of E

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

Here's a graph comparing the Discoverer AT3 XLT and All-Terrain T/A KO2 tyres for fuel efficiency (1 = Grade E, 5 = Grade A).

Grip & Handling

EU Grade
(A - E)
Compared to an A grade tyre?
Discoverer AT3 XLTD7.5 metre greater stopping distance when braking at 80km/h
All-Terrain T/A KO2B2.5 metre greater stopping distance when braking at 80km/h

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 Discoverer AT3 XLT tyres rank a D on a scale of A to E in the official fuel tests carried out by the EU.

The All-Terrain T/A KO2 tyres, on the other hand, get a grade of B.

Expect the lower graded tyres to require about an extra 5 metres to come to a complete stop when braking at 80km/h.

Here's a graph comparing the Discoverer AT3 XLT and All-Terrain T/A KO2 tyres for wet grip (1 = Grade E, 5 = Grade A).

Noise

EU Grade
(A - C)
Compared to an A grade tyre?
Discoverer AT3 XLTB (73.0 dB)2 times as noisy
All-Terrain T/A KO2B (74.3 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 Discoverer AT3 XLT tyres produce 73.0 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 All-Terrain T/A KO2 tyres produce 74.3 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 Discoverer AT3 XLT and All-Terrain T/A KO2 tyres stack up for noise (1 = Grade C, 3 = Grade A).

Comfort

Based on the results of a number of tyre benchmarks, the Discoverer AT3 XLT scores 5 out of 5 for comfort and the All-Terrain T/A KO2 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 Discoverer AT3 XLT tyres have a treadwear rating of 620, which means that they would last 6.2 times longer than a tyre with a rating of 100. There's no treadwear data available for the All-Terrain T/A KO2 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 Discoverer AT3 XLT tyres have a traction grade of A (on a scale of AA, A, B, C). There's no UTQG traction grading data available for the All-Terrain T/A KO2 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 Discoverer AT3 XLT tyres have a temperature resistance grade of B (on a scale of A, B, C). There's no UTQG temperature resistance grading data available for the All-Terrain T/A KO2 tyres.

Warranty

The All-Terrain T/A KO2 tyres have a warranty of 6 years. There is no time-based warranty available for the Discoverer AT3 XLT.

In terms of distance, the Discoverer AT3 XLT tyres have a warranty of 80,000 kilometres. There is no distance based warranty available for the All-Terrain T/A KO2.
