How We Reviewed The Discoverer ATT 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 21 sizes of the Discoverer ATT tyres by the European Union.

We then compare these to the same results for the following similar tyres, also rated for On-/Off-Road All-Terrain usage and sold in Australia.

Fuel Efficiency

EU GradeCompared to an A grade tyre?
Fuel Efficiency
(A - E)
C0.2L/100km extra fuel consumption. ~$53 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 ATT 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).

Relative to an A grade tyre, expect to use an extra 0.2L/100km. This works out to $53 extra spent on petrol per year, based on a typical 12,000 km driven per year.

Comparison

Here's how the Discoverer ATT compares to similar tyres for fuel efficiency (1 = Grade E, 5 = Grade A).

Based on the comparison tyres we've selected, the Discoverer ATT ranked # out of 0 tyres.

Grip & Handling

EU GradeCompared to an A grade tyre?
Wet Grip
(A - E)
C5 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 ATT tyres rank a C on a scale of A to E in the official fuel tests carried out by the EU.

Relative to an A grade tyre, expect these tyres to require about an extra 5 metres to come to a complete stop when braking at 80km/h.

Comparison

Here's how the Discoverer ATT compares to similar tyres for wet grip (1 = Grade E, 5 = Grade A).

For wet grip, they scored # out of 0 comparison tyres.

Noise

EU GradeCompared to an A grade tyre?
Noise
(A - C)
B (72 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 ATT tyres produce 72.3 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.

Expect these tyres to produce about 2 times as much noise as an A grade tyre (the decibel scale is logarithmic).

Comparison

Here's how the Discoverer ATT compares to similar tyres for noise (1 = Grade C, 3 = Grade A).

For noise, they ranked # out of 0 comparison tyres.

Treadwear

With a UTQG treadwear rating of 620, the Discoverer ATT would theoretically last 6.2 times longer than a tyre with a treadwear rating of 100.

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.

These tyres score a grade of A.

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.

These tyres score a grade of A.

Warranty

The Discoverer ATT tyres have a warranty of 80,000 kilometres.

Summary

The Discoverer ATT tyres are a solid choice for anyone looking to replace their SUV or truck rubber with some tyres designed for on-/off-road all-terrain action.

For fuel efficiency, they score a grade of C, which is more or less average, though this isn't a super important factor.

More important is the wet grip, which gives you an indication of their traction and handling. In this regard, they get a score of C, which is more or less average.

Finally, for road noise, they receive a B grade, which is about typical.

In terms of data out of the US, they have the following UTQG ratings:

  • Treadwear: 620
  • Traction: A (scale: AA, A, B, C)
  • Temperature Resistance: A (scale: A, B, C)
