The 2023 AMS SUV winter tire test not only aims to answer what the best winter tire in 255/45 R20 is, but also to find out if swapping from a regular diesel Kia Sorento to a fully electric Kia EV6 will make a difference to the results.

The answer to the question about the tires is below, and the answer to the question about the IC vs EV is that it made no difference to the traction, braking or handling order of the results, but the tester did prefer the IC Kia Sorento on snow as they felt the traditional differentials were more predictable when the front and the rear was locked mechanically. The tested noted that the separate front and rear axle power units of the electric vehicle each had "individual motivation" when sliding around on snow.

255/45 R20 is quite frankly bonkers for a winter tire, so the results should be interesting, especially as they have new tires from Goodyear, Pirelli and Falken!

Dry

During dry braking, the Pirelli Scorpion Winter 2 and Bridgestone Blizzak LM005 are closely matched, with braking distances of 43M and 43.1M respectively. Bridgestone slightly edges out Goodyear, but both are strong contenders in dry conditions.

Bridgestone Blizzak LM005 and Continental WinterContact TS 870 P share the top spot with an average lap speed of 117.5 Km/H. Bridgestone shows its versatility here, excelling in both dry braking and handling.

Wet

Bridgestone Blizzak LM005 leads in wet braking with a 32.6M distance, reinforcing its strong all-around performance.

Goodyear UltraGrip Performance 3 slightly outperforms the rest during wet handling, with an average lap speed of 79.3 Km/H, closely followed by Bridgestone Blizzak LM005 at 79.2 Km/H. 

The best performer in the Wet Circle category is Bridgestone Blizzak LM005 with an average lateral acceleration of 7.31m/s. This tire also leads in wet braking, making it a strong choice for wet conditions.

Bridgestone Blizzak LM005 leads again with the highest float speed of 77.5 Km/H in straight aquaplaning, reinforcing its all-around strong performance in both dry and wet conditions.

The top performer in Curved Aquaplaning is again the Bridgestone Blizzak LM005. This adds to its strong performance in wet conditions, particularly in wet braking and wet circle.

Snow

Michelin Pilot Alpin 5 SUV leads in snow braking with an average stopping distance of 29.8M, and it also excels in snow handling, making it a strong performer in snowy conditions.

Michelin Pilot Alpin 5 SUV leads with in snow traction, reinforcing its strong performance in snowy conditions.

Michelin Pilot Alpin 5 SUV takes again the lead in snow handling with an average speed of 48.2 Km/H. It's a tire that performs well across various conditions, from dry to snowy.

The Pirelli Scorpion Winter 2 leads snow circle.

Comfort

Michelin Pilot Alpin 5 SUV is the quietest in the drive by external noise test of 71.2 dB, adding to its list of strong performances across multiple categories.

Value

Bridgestone Blizzak LM005 has a rolling resistance of 7.1 kg/t, making it the most eco-friendly option of the tires on test.
