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 104 sizes of these tyres by the European Union.

Fuel Efficiency

EU Grade
(A - E)
Compared to an A grade tyre?
Crugen HP71C0.2L/100km extra fuel consumption. ~$58 extra per year
Crugen HP91D0.3L/100km extra fuel consumption. ~$61 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 Crugen HP71 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 Crugen HP91 tyres get a grade of D

Expect the lower grade tyre to consume an extra 0.0L/100km. This works out to $3 extra spent on petrol per year, based on a typical 12,000 km driven per year.

Here's a graph comparing the Crugen HP71 and Crugen HP91 tyres for fuel efficiency (1 = Grade E, 5 = Grade A).

Grip & Handling

EU Grade
(A - E)
Compared to an A grade tyre?
Crugen HP71C5 metre greater stopping distance when braking at 80km/h
Crugen HP91B2.5 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 Crugen HP71 tyres rank a C on a scale of A to E in the official fuel tests carried out by the EU.

The Crugen HP91 tyres, on the other hand, get a grade of B.

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 Crugen HP71 and Crugen HP91 tyres for wet grip (1 = Grade E, 5 = Grade A).

Noise

EU Grade
(A - C)
Compared to an A grade tyre?
Crugen HP71B (71.3 dB)2 times as noisy
Crugen HP91B (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 Crugen HP71 tyres produce 71.3 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.

On the other hand, the Crugen HP91 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 Crugen HP71 and Crugen HP91 tyres stack up for noise (1 = Grade C, 3 = Grade A).

Comfort

Based on the results of a number of tyre benchmarks, the Crugen HP71 scores 4 out of 5 for comfort and the Crugen HP91 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 Crugen HP71 tyres have a treadwear rating of 640, whereas the Crugen HP91 tyres have a rating of 420. This means that the Crugen HP71 tyres will theoretically last 1.5 times as long as the Crugen HP91 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 Crugen HP71 tyres have a traction grading of A, whereas the Crugen HP91 tyres have a grading 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.

As per the UTQG system of tyre grading, the Crugen HP71 tyres have a temperature resistance grading of A, whereas the Crugen HP91 tyres have a grading of A (on a scale of A, B, C).

Warranty

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