2023 The Best Electric Vehicle Tyres VS UHP Tyres

It's not often I'm completely shocked by a tyre test, but this years AMS EV tyre vs normal tyre test has me stumped.

Why? Let me run a few things past you. The Michelin e.Primacy was best in wet braking, beating both the Continental SportContact 7 and Bridgestone Potenza Sport, which usually ace that test. The Michelin e.Primacy also beat the Michelin Pilot Sport 4 SUV overall, which has won every other test it's featured in, and Continental won the test twice!

The concept for the test seems relatively straightforward - get a bunch of the best performance tyres on the market and test them against the newest ultra low rolling resistance / EV tyres, the Michelin e.Primacy, the Falken eZiex and the Pirelli Scorpion Elect.

Things get l little more complicated as AMS also included the Kia EV6 OE version of the Continental PremiumContact 6, and the acoustic foam version of the Michelin Pilot Sport SUV. And they used two test vehicles, an EV Kia EV6 and a diesel Kia Sorento. Quite which did what escapes me, so if you want to know you should go check out the full AMS test on their website or magazine.

Wet

Wet braking is the test that's raised the most eyebrows in the industry. Traditionally the wet performance of a tyre is an opposing requirement of rolling resistance / energy use, highlighted by the fact the the Michelin e.Primacy has never had a good wet braking result against its rivals. Don't believe me? Check out the other tests linked from here.

In this test, the e.Primacy was not only best of the other EV tyres, it was best of all the tyres! Perhaps it was something to do with the rather large 255/45 R20 tyre size tested, or perhaps it was due to a very high grip wet braking surface (look at the distances!) but the data had the e.Primacy at the top, and the new Falken eZiex in second, both ahead of their much higher rolling resistance counter parts, the Michelin Pilot Sport 4 SUV and Falken Azenis FK520.

Fortunately wet handling had the tyres in a more expected order, with the ultra low rolling resistance tyres struggling to get the Kia around the lap compared to the wet master, the Bridgestone Potenza Sport.

The ultra low rolling resistance tyres were also amongst the worst in the aquaplaning tests, which is often a feature of the shallower starting tread depth and less water channels of tyres designed to save energy.

Dry

Dry braking had both the Continental products at the front, with four tyres tied for fourth place!

The sport-bias UHP tyres led the way in the dry handling laps, with the Continental SportContact 7 having an impressive margin.

Environment

The magazine tested the rolling resistance of the tyres, which is a machine test, and the energy consumption in the real world using the Kia EV6.

The EV tyres led the real world test, with the Falken Azenis FK520 tying with the eZiex on the drum test. As we've seen before, the Bridgestone Potenza Sport isn't the tyre to buy if you care about your energy use!

The three EV tyres also had the lowest external passby noise, another feature of the low tread depth, BUT the testers did comment that the Michelin Pilot Sport 4 SUV with acoustic foam was noticeably quieter in the cabin meaning the sound deadening foam applied to the inside of the tyre was doing its job well.

There was quite a range in tyre prices, with Michelin being the two most expensive products in the test.

Results

Please note: Continental claim the SportContact 7 should have over 7mm of tread depth, but in the interest of fairness, I've databased what was listed in the magazine. Based on my own measurements in a different tyre size of the SC7, it seems most likely that the magazine is incorrect.

Continental SportContact 7

255/45 R20 105Y

• EU Label: C/A/73
• 3PMSF: no
• Weight: 12.44 kgs
• Tread: 5.87 mm

Maximum aquaplaning safety, very balanced wet safety with strong understeer, works well with the ESP control system. Very short braking distances dry.

Strong understeer even in the dry, increased tyre noise.

The SC7 is a sporty, efficient all-rounder with high safety reserves.

255/45 R20 101Y

• EU Label: B/A/72
• 3PMSF: no
• Weight: 13.42 kgs
• Tread: 6.33 mm

Very short dry braking, Safe balance, good handling in the wet and in the dry. Very low drive-by and interior noise.

Compared to the Conti SC 7, the steering behavior is more sluggish, the tendency to understeer is more pronounced and the level of grip is somewhat lower.

The Kia EV6 OE version of PC6 was tested in this test. It is very quiet on the EV6 - technically no longer up to date as the PC7 is on the market.

Outstanding cornering grip on wet and dry roads, combined with very precise handling characteristics - a very sporty tyre.

Long braking distances in the wet, sensitive to temperature. Increased rolling resistance and louder pass-by noise, somewhat rumbling in the cabin.

The Potenza Sport is the sportiest tyre in the field - the tyre to buy when efficiency isn't a priority.

Good aquaplaning protection, safe lane changes in the dry, very quiet and comfortable tyre in the car.

Too long braking distances in the wet (devaluation), poorly balanced wet handling with oversteer and understeer, seems a bit overwhelmed when driven in a sporty manner given the high vehicle weight.
