Every measurement, side by side
Averages of the figures both tires posted in the same tests. The gap is the average of each test's own gap, so figures from different cars and years are never mixed. Open a discipline for its measurements, and a measurement for every test's figure.

Braking distances and lap times are better when lower; speeds, wear and grip figures when higher. A test's figures are its own: sizes, cars, surfaces and temperatures differ from one to the next, which is why the averages here are only ever of tests the two tires shared. "Scored" rows are subjective driver ratings: each test uses its own scale, so only the wins are counted.

Hankook iON FlexClimate
- 88%from 11 reviews
- 91%would buy again
- 100,500 milesdriven by reviewers
Owners overwhelmingly rate the Hankook iON FlexClimate highly, with most highlighting very low road noise and a comfortable, refined ride. Many also report strong all-round grip, particularly in the wet, and several found it impressively capable in snow and on ice for an all-weather tire. The main recurring drawback is efficiency, with around one in five owners noting reduced EV range/rolling resistance, while isolated comments mention slightly weaker dry handling or a touch more noise as it wears.
- Very low road noise
- Comfortable, compliant ride
- Strong wet grip and confidence in rain
- Good dry grip
- Reduced efficiency / higher rolling resistance impacting range
- Slightly weaker dry handling than summer tires
- A little noisier as it wears

Vredestein Quatrac Pro EV

All 2 Quatrac Pro EV reviewsI have always trusted the Vredestein brand for their winter tires. I chose this brand for all-season tires in the UK. Overall, I find their performance to be excellent, but I was disappointed with the wear on the traction wheels. I fitted 255/45R19 tires on my ID.7 and mostly drive in Eco mode, with slow acceleration and braking through regenerative means. Unfortunately, the tires lasted less than 20,000 miles.

Reading the results
Written from the test results and owner reviews above. It is analysis, not a measurement: where it and the tables disagree, the tables are right.
Both the Hankook iON FlexClimate and Vredestein Quatrac Pro EV target the same brief: EV-specific, all-season tires that blend year-round safety with range efficiency for modern electric passenger cars. With identical intent but different executions, they've been measured in like-for-like sizes across two independent test programs, including Auto Bild's EV mini-test (245/45 R19) and a TÜV benchmark session (235/45 R18).
Across these shared tests, the Hankook consistently led every measurable safety metric-dry, wet, aquaplaning, and snow-often by meaningful margins. The Vredestein counters with a comfort-focused character and low noise, but its winter shortfall and weaker wet braking place it firmly behind the Hankook for all-weather security.
Conclusion
The pattern is unequivocal: Hankook's iON FlexClimate dominates the objective data, winning both shared tests and every key safety category, including wet braking (up to 16.7% shorter) and snow performance (up to ~18% shorter snow stops). It also delivers lower rolling resistance (Auto Bild) and sharper steering, making it the more rounded EV all-season option for real-world climates.
Vredestein's Quatrac Pro EV suits drivers who value ride comfort and quietness in milder regions, but its deficits in snow and wet stopping distance make it harder to recommend as a four-season safety net. For most EV owners, especially where rain and occasional snow are realities, the Hankook is the clear, confidence-inspiring choice. If you rarely see winter and prioritize cabin refinement, the Vredestein remains a viable, comfort-led alternative.

Where this data comes from
Finishing positions and measurements are transcribed from each published test. A test only counts here when both tires ran in it, so every figure was recorded on the same car, size and day as the one it is compared to.
About the TR Score
The Tire Reviews Score rates each tire out of 10 from every independent test result and vetted owner review we hold, so two tires can be compared even before a test has run them together.
Who does the testing
Every test published as a Tire Reviews test is run by Jonathan Benson, who has been testing tires independently since 2007.
