Nokian WetProof vs Michelin Primacy 4+
The Nokian WetProof and the Michelin Primacy 4+ have met in one independent test so far, and the Primacy 4+ finished ahead. The WetProof was stronger in wet, the Primacy 4+ in dry and value.
Performance profile
10 measurements from the one shared test, each tire shown as its share of the better figure.
Where each is furthest ahead
WetProof
Primacy 4+
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 96%: a point further in sits on the hub's edge, hollow.

Category scores are percentiles among tires of the same season and class: 90 means this tire out-performs 90% of them, measured across every test we hold, not only the ones it appeared in.
Where owners rate each higher
WetProof
Primacy 4+
Point at or tap any spoke for both tires' figures.
Owners rate the WetProof 81% from 25 reviews and the Primacy 4+ 79% from 40. Each spoke is one question owners answer out of 10; reviews are vetted by hand before publication.
Every measurement, side by side
Both tires' figures from the one test that ran them together, on the same car, in the same size, on the same day. The bar grows towards the tire that did better.

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.
Head to head in 1 test in 2023
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.

Your review is the part of this page no test can supply: how the tire wore, how it aged, what it was like in the rain in year three. It takes about five minutes.
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.
