Comparison: Hankook ION Evo vs. Firestone Roadhawk 2 (2026)

No valid head-to-head average wet braking distance is available because the data supplies no measured Hankook distance. Firestone recorded 38.3 metres in one wet-braking test and 51.1 metres in another, averaging 44.7 metres across those two measured results; that is a Firestone-only average, not a direct comparison. Its wet-braking score is 66.7, whereas Hankook's is 97. The ION Evo is consequently the much stronger emergency-stopping proposition, supported by its short-braking test feedback and EU wet-grip distribution of 95% A-rated sizes, 3% B and 2% C.

Firestone's wet character is unusually split. Almost every size, 99%, carries an EU A wet-grip label, yet the independent results show that this label does not guarantee class-leading wet braking or handling. Wet handling scores 79.7 and wet-circle cornering 76, while testers found restricted adhesion reserves, weak steering information and unstable behaviour during load changes, particularly on wet asphalt. From 100 km/h, its 44.7-metre two-test average represents roughly nine car lengths of stopping space. The practical message is to preserve a larger gap even though the label and normal-speed behaviour appear reassuring.

Standing water is where the Roadhawk 2 becomes exceptional. It scores 91.2 in longitudinal aquaplaning and 94 across transverse aquaplaning, won both aquaplaning disciplines in one comparison and produced a class-leading 2.44 m/s² in the curved-water test. Wide shoulder lugs, chamfered sipes and optimized void-to-rib proportions give displaced water an efficient escape path. Hankook is also strong, scoring 82 for aquaplaning and receiving praise for good safety reserves, but Firestone is the specialist choice in cloudbursts and deep motorway ruts. On a merely wet, twisting road, however, Hankook's 88.8 overall wet score and superior braking authority provide the more coherent, confidence-building package.

A comparable average dry braking distance cannot be calculated from the supplied results: no measured Hankook distance is provided, while the Firestone's available evidence includes 35.4 metres in one test, where it finished last, plus a seventh-place dry-braking result elsewhere. It would therefore be misleading to manufacture a two-tyre average or claim a precise stopping gap. The scoring nevertheless separates them clearly: Hankook records 91 for dry braking and 91.5 overall dry performance, against 66.5 and 61.5 respectively for Firestone.

That difference should be most apparent during emergency braking and fast direction changes. The ION Evo's aramid reinforcement is designed to limit tread deformation at speed, while its extended outer shoulder blocks resist the slip generated by an EV's instant torque. More uniform contact pressure also helps keep a larger, more consistent footprint working under braking. The result indicated by the tests is not merely greater peak grip but better-managed grip: short braking, excellent dynamics and enough structure to keep a heavy car settled through rapid steering inputs.

The Roadhawk 2 remains secure enough for normal road use, with a 73.8 dry-handling score, 80 for the dry lane-change discipline and positive evidence of good cornering safety. Its weakness is the transition from everyday pace to the limit. Steering response can be delayed, feedback weak and ultimate adhesion limited; long dry stopping distances reinforce that impression. Connected shoulder blocks distribute pressure effectively, but its efficiency-led lightweight construction and touring priorities do not produce the Hankook's braking authority or immediacy. Drivers will feel this as an extra pause before the tyre takes a set and less information as grip runs out.

Firestone has the numerical advantage in refinement, scoring 79.8 for comfort and 83.2 for noise, compared with Hankook's 72 and 66. It was the quietest tyre in one test, so its broad touring brief is more than marketing. There are qualifications: another assessment identified slightly poorer impact comfort, and passing noise was not always outstanding. Even so, its general character is calm and unobtrusive. That suits long trips, family cars and drivers who rarely approach the adhesion limit.

Hankook counters with technology tailored to the near-silence of an EV cabin. Its internal i Sound Absorber foam is intended to suppress the hollow cavity resonance that becomes conspicuous without engine noise, while Opti Pitch varies tread-block sequencing to reduce tonal noise. Tests describe its comfort as good, but the aggregate noise score shows that the claimed refinement is not universally dominant. Owners are divided too: some call it quiet and comfortable, while others regard its grip as only average beside Michelin Pilot Sport 4 or 5 and markedly below Bridgestone Potenza Sport. Reports of slip during acceleration or cornering remind buyers that an EV-specific balance is not the same as maximum sports-tyre grip, despite the strong controlled-test scores.

Running-cost evidence is more complicated. Hankook scores 82 for mileage against Firestone's low 38, and its ProDurable compound plus Round Even Technology directly target the approximately 20% faster uneven wear that Hankook associates with EV use. Its fuel labels are also excellent: 52% of sizes achieve A, 45% B and only 3% C. Firestone's range is predominantly B-rated for efficiency at 70%, with 27% C and just 3% A. It nevertheless recorded a best-in-test 8.0 kg/t rolling resistance in one comparison and has a higher aggregate rolling-resistance score, 74.8 versus 69. Conflicting feedback elsewhere found high resistance and consumption, illustrating how size, vehicle and test method matter.

Firestone's lower purchase position is tangible: one test listed it at €132, and its 108-size range makes fitment easier. Yet low entry price does not automatically mean low lifetime cost. Although Firestone claims 20% more mileage than the original Roadhawk, independent evidence still flags distinctly restricted longevity. Hankook's better mileage score, more consistently strong fuel labels and ability to control EV wear make it the stronger long-term value for a powerful or heavy electric car. Firestone offers attractive immediate value for moderate-mileage drivers, particularly where purchase price and quiet cruising matter more than replacement interval.
