298 The New Tyre Update Episode

Hankook Ion Evos are an EV-focused tire line from Hankook. The key idea is that EV tires are designed to reduce rolling resistance and noise while supporting the specific demands of electric vehicles.

The Polestar 2 is an electric liftback from Polestar, and it’s a good example of how tire choice can affect real-world EV behavior. In this episode, the host uses the Polestar 2 to compare road noise and efficiency before and after swapping tires.

Davanti is a tire brand, and in this episode the host describes Davanti tires as “budget tyres.” The comparison matters because the host says the Davanti tires produced more road noise on the Polestar 2 than the EV-focused Hankook set.

Road noise is the sound generated when tires interact with the road surface. EVs are often quieter than gas cars, so tire noise can become more noticeable, making tire tread and construction a major factor in perceived cabin quietness.

Formula E is a top-level electric racing series, and it’s used here as a credibility link for tire development. The host is saying the Hankook Ion tires are based on rubber technology from Formula E racecars, implying they’re optimized for EV-style traction and energy use.

Ion Flex Climate tyres are an all-weather EV tire variant from Hankook’s Ion line. The host contrasts them with his own summer-style Ion Evos, which helps explain why the episode compares efficiency and noise across different seasonal tire types.

All-season tires are designed to provide acceptable traction in a wide range of temperatures, aiming to balance dry/wet grip with moderate cold-weather performance. In this segment, the speaker credits all-seasons with better confidence on icy roads compared with what they’d seen other drivers do.

Ion Flex Climate SUV is a tire model described as an all-season option in the segment. The speaker says they chose it because their previous tires were also all-season, and they’re evaluating changes in handling, noise, and efficiency.

The Ford Flex is a full-size, family-oriented crossover/MPV-style vehicle known for its roomy interior and practical layout. It’s the kind of vehicle that often gets discussed in the context of tires and everyday usability, especially when people talk about all-season options for year-round driving. In this podcast context, it’s mentioned alongside specific tire types and fitment for a “climate” all-season setup.

Goodyear Vector four-seasons is a tire model line aimed at providing year-round traction. In the segment, it’s the previous tire the speaker had, and they choose the new tires to “swap like for like” to keep the comparison fair.

The Volkswagen Eos is a compact luxury car that was produced with a focus on comfort and style, including a distinctive retractable roof design on many models. In the podcast context, “EOS” is being used as a tire/model name associated with electric-vehicle fitment rather than describing the car’s powertrain. That’s why it comes up alongside “Ion Flex” and “Climate SUV” tire references.

“EOS” is referenced as an EV-specific tire line associated with Ion, and the speaker contrasts it with all-season tires. The key point is that some tires are marketed specifically for electric vehicles, often targeting rolling resistance and noise characteristics that affect real-world efficiency.

Summer tires use rubber compounds and tread designs optimized for warm temperatures, typically delivering stronger dry and wet grip than all-seasons—but they generally lose performance in cold weather. The speaker notes they still use them year-round, while acknowledging they’re “summer” tires in name.

In tire discussions, “handling” refers to how the car responds to steering inputs—especially grip and stability during cornering and on slippery surfaces. The speaker evaluates whether the new tires changed the e-Niro’s feel, concluding there was little difference because both sets were already good in bad weather.

“Driving more efficient” in an EV context usually means improving energy use—how many miles you get per unit of battery energy. Tire choice can affect this through rolling resistance and how much grip is needed to maintain speed, which is why EV-specific tire lines are marketed as efficiency-focused.

The Kia e-Niro is an electric compact crossover built around a comfort-focused, everyday driving setup rather than track-style handling. In the segment, it’s used as a baseline to explain that the car wasn’t expected to be a handling “master” even before the tire change.

Braking distance is the length of road a car needs to slow down and stop after the brakes are applied. It’s influenced by tire grip, tread condition, and road surface conditions—especially in wet weather. The host claims they didn’t notice any increase in braking distance with the new tires.

Aquaplaning is when a tire loses contact with the road because there’s too much water under it, so the tire can’t channel water away effectively. That loss of traction can make braking and steering feel suddenly unreliable. New tires can improve resistance to aquaplaning by maintaining better tread depth and water evacuation.

Decibels (dB) are a logarithmic unit used to measure sound level. Here, the hosts use an app to record average/high decibel readings during the same journey so they can compare tire noise between old and new tires.

Hankook (spoken here as “Hankooks”) is a tire brand. In this segment, the hosts compare tire noise using an app, reporting lower average decibel readings on the Hankook tires versus the older tires.

Goodyear is a major tire brand. The hosts use decibel readings from repeated drives to compare the older Goodyear tires against newer Hankook tires, with the Goodyear set measuring slightly higher noise.

In an EV context, “efficiency” usually means how much energy the car uses to travel a given distance. Tires can affect this because rolling resistance changes how much power the drivetrain needs, which in turn impacts how far the battery can take you.

“Miles per kilowatt-hour” (mi/kWh) is an EV energy-consumption metric: how many miles you can drive per unit of electrical energy from the battery. Higher mi/kWh means the car is using less energy per mile, often reflecting lower rolling resistance and/or better overall tire behavior.

“Miles per kilowatt hour” (mi/kWh) is an EV efficiency metric that tells you how far the car can travel on one unit of battery energy. Higher mi/kWh means the EV is using less energy per mile, which usually improves range.

“handcooks” appears to be a misspoken reference to Hankook tires. The host credits the new Hankook tires with a measurable efficiency and noise improvement compared with their previous tires.

A “kilowatt hour” (kWh) is a unit of electrical energy, and EV battery capacity is commonly measured in kWh. When the host multiplies mi/kWh by “78 kilowatt hours,” they’re estimating how many miles the full battery could cover at that efficiency.

“Goodyers” is almost certainly a reference to Goodyear tires, which the host says are similar to the new tires in feel and noise. The point is that the tire swap didn’t drastically change the driving experience beyond improved quietness.

Hancock is mentioned as the person who fitted the tires, implying they handled the installation. In this segment, the brand name is used as a service/installer reference rather than a tire model.

Rolling resistance is the energy lost as a tire deforms while rolling. Lower rolling resistance generally improves efficiency for EVs because the car needs less energy to maintain speed.

A control group is a baseline set of conditions used to compare against the “test” group. Without a control group, it’s harder to prove that the tire change caused the efficiency/noise differences rather than weather, traffic, or driving style.

EV-specific tires are designed for electric vehicles, typically prioritizing low rolling resistance to help range and often tuning noise and ride comfort for EV weight and torque delivery. They may use different rubber compounds and tread designs than conventional tires to reduce energy loss as the tire rolls.
