Bridgestone Alenza 001 vs Michelin Primacy SUV [Test Data]

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 Alenza 001 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 Primacy SUV 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 Alenza 001 and Primacy SUV 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 Alenza 001 tyres rank a B on a scale of A to E in the official fuel tests carried out by the EU.

The Primacy SUV tyres, on the other hand, get a grade of B.

As their wet grip grade is the same, expect negligible differences in terms of braking distance.

Here's a graph comparing the Alenza 001 and Primacy SUV 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 Alenza 001 tyres produce 71.8 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 Primacy SUV tyres produce 69.8 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 Alenza 001 and Primacy SUV tyres stack up for noise (1 = Grade C, 3 = Grade A).

As per the UTQG guidelines, the Alenza 001 tyres have a treadwear rating of 300, whereas the Primacy SUV tyres have a rating of 440. This means that the Alenza 001 tyres will theoretically last only 68% as long as the Primacy SUV tyres.

As per the, the Alenza 001 and Primacy SUV tyres both have a traction grading of A.

As per the UTQG system of tyre grading, the Alenza 001 and Primacy SUV tyres both have a temperature resistance grading of A.

For fuel efficiency, Alenza 001 score a grade of C, which is more or less average. Primacy SUV 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, both the Alenza 001 and the Primacy SUV get a score 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, Alenza 001 get a score of B, which is about typical. Primacy SUV end up with a grade of B, which is about typical.
