Wins count every measurement the shared tests recorded for both tires; a tick marks the tire ahead on that line. Subjective driver scores count as wins but are never averaged, because each test uses its own scale.
Head to head in 4 tests, 2024 to 2025
Each row is one published test in which both tires ran on the same car, in the same size, on the same day. The line is the whole field, winner on the left.

Point at or tap any spoke for both tires' figures.
In each test the better of the two figures counts as 100% and the other as its share of it, so a 118 ft stop against 112 ft is 95%; each spoke averages the shared tests that recorded it. The scale stops at 95%: a point further in sits on the hub's edge, hollow. 10 measurements recorded in only one shared test are left off; every measurement is in the table further down.

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.
Scores beyond the shared tests

Dunlop All Season 2
- 70%from 7 reviews
- 43%would buy again
- 47,065 milesdriven by reviewers
Drivers' feedback on the Dunlop All Season 2 is mixed but generally favorable, with the highest-scoring reviews strongly praising confident all-season traction-especially in wet and colder conditions-and good real-world mileage. Several users also describe it as good value and secure in everyday driving. A smaller but recurring set of comments mentions noticeable noise/squeal and less satisfying handling/understeer on warmer, dry roads; one very low score reports poor sidewall durability but this is not widely echoed.
- Strong grip/traction in wet and cold conditions
- Good all-season versatility (including light snow capability)
- Good tread life/mileage when maintained
- Good value for money
- Noticeable road noise/squeaking
- Less precise handling on warm/dry roads (can feel like understeer)
Summarised by AI from 7 vetted reviews; the reviews themselves are on the tire page.
All 7 All Season 2 reviewsFrom my experience tire is very good in cold, wet and damp condition. On dry and warmer asphalt not so great at handling.
Wear is expetional, they wear very little.

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.
Dunlop All Season 2 and Viking Fourtech Plus target the same all-season touring brief, but they go about it differently. Across four shared tests in 2024-2025, Dunlop consistently posts shorter dry stops and markedly stronger longevity, while Viking counters with better aquaplaning resistance and flashes of wet braking speed.
In objective rankings, Dunlop generally finishes ahead (three comparative wins to Viking's one), driven by superior wear, abrasion, and value. Viking, however, proves competent in dynamic wet safety margins thanks to stronger straight-line and curved aquaplaning results and competitive handling feel in some sizes.
Conclusion
Overall, Dunlop All Season 2 is the more rounded, higher-value option. It brakes shorter on dry in every shared test, is materially better on snow/ice braking and traction, and dominates durability: +40% to +63% higher projected mileage and lower abrasion. Those advantages translate into fewer replacements and lower running costs, reinforced by Dunlop's better price/value scores.
Viking Fourtech Plus earns its case with wet-road security reserves: it edges Dunlop in aquaplaning and posts a couple of wet-braking wins, with safe, predictable manners. If your priority is wet-weather standing-water performance over the long haul, Viking is a sensible budget-leaning pick. For most drivers seeking balanced safety year-round and long service life, Dunlop is the clear choice.

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.
