Bridgestone Blizzak WS90 vs Bridgestone Blizzak DM V2

Bridgestone Blizzak WS90 and Bridgestone Blizzak DM V2 are both winter tires built for optimized performance in winter conditions like cold temperature, icy roads or snow covered pathways. WS90 offer smooth drives over tracks covered with soft snow due to its higher evacuation capacity, it also provides firm steer handling over corners.

On the other side, DM V2 provides excellent grip on all kinds of roads whether dry, wet or icy owing to high contact patch and enhanced biting ability of its denser tread.

Vs

Bridgestone Blizzak WS90

WS90 exhibits a symmetrical tread design with a unique continuous, crisscross central rib having two massive grooves on its sides, zigzag sipes, notched edges and discontinuous groove passing through shoulders. Void ratio is relatively higher and minimizes contact patch which eventually cause reduction in grip of tread over dry roads. Open channels and sipes remove water and provide dependable aquaplaning resistance over wet tracks. High void ratio proves beneficial when it comes to dealing with light snow over the road, snow is effectively evacuated through its broad grooves while moving ahead.

DM V2 characterizes a symmetrical and directional tread pattern with two main wide, longitudinal grooves along with zigzag spacing among central ribs forming two narrow grooves, 3D zigzag sipes, triangular blocks with saw-tooth edges over central ribs and square shaped shoulder lugs. Denser arrangement of lugs and low void ratio in central ribs makes contact patch of tread higher, increasing its ability to hold on the surface tightly, as a result dry grip is maximized. Slanting voids and 3D zigzag sipes provide good aquaplaning resistivity and account for excellent grip on wet and icy roads, less angular shoulder lugs without traction notches/edges make handling a bit difficult as compared with its competitor. Relatively low void ratio decreases snow traction in comparison as soft snow evacuation capacity of its grooves is lesser than WS90.

Overall Grip Comparison

WS90 shows lesser grip on hard paved roads owing to its high void ratio. Broad grooves along the sides of central rib and dashed longitudinal grooves passing along shoulder lugs reduce contact patch of tread in comparison, as a result dry grip is minimized. Although lesser number of sipes on WS90 decrease traction over wet and icy roads as compared with its competitor yet its large grooves and zigzag sipes wipe away watery substances, providing reliable hydroplaning resistance. On the other hand, its high void ratio favors it while roaming about snow covered areas as its massive grooves can throw out snow and slush, cleaning tread and clearing its pathway as it rolls forward.

DM V2 has two major longitudinal grooves and spaces among blocks of central ribs, this arrangement leads to low void ratio and higher contact patch, resulting as superior grip of tread on dry tracks. Biting edges of its blocks further enhance its grip. Grip of DM V2 over wet roads and icy surfaces is better than its competitor as it has greater number of 3D zigzag sipes for wiping away slippery liquids efficiently. Thus, it shows lesser braking distances on all three; dry, wet and icy roads. However, this tire performs lesser in comparison when rolling over surfaces covered with soft snow. It has decreased efficiency to evacuate snow in backward direction due to lower void ratio.

Handling Comparison of the tires

WS 90 performs superior in terms of dry handling as its shoulder lugs are relatively larger, have more biting edges and maintain firm traction as the vehicle steers along the corners. Wide circumferential sipes along with thin horizontal sipes and a discontinuous groove provide enough space for removal of water and account for stable traction while cornering over wet and icy roads.

When it comes to handling the vehicle over tricky turns on dry roads, DM V2 loses the competition as its blocks have lesser contact patch and decreased biting ability. Small, squared shoulder lugs cannot maintain traction strongly while steering along corners over dry roads. The same story goes over wet and icy roads but frequent siping improves traction on wet/icy roads, to some extent.

Comparison of Hydroplaning Resistance

Both tires show excellence in terms of hydroplaning resistance due to their distinguished tread designs, however, DM V2 seems winning owing to higher number of sipes and angular grooves among blocks of central ribs. Numerous 3D zigzag sipes and slanting voids efficiently wipe off slippery liquids from the surface and allow the tread to grip firmly on paved area as a result of better aquaplaning resistance.

WS90 has reliable aquaplaning resistivity but its ability to wipe away disturbing fluids is slightly lesser in comparison as number of sipes is lesser and its lateral grooves are relatively straight and less angular. However, massive grooves, zigzag sipes and crisscross design of central rib account for wiping away watery substances and resist hydroplaning satisfactorily but the competitor takes the lead in this respect.

Comparison of Rolling Resistance

WS90 is fuel efficient in comparison as it needs less energy to roll over the roads. High void ratio reduces surface area of tread in contact with road, minimizing hysteresis produced and leading to lesser rolling resistance.

As DM V2 has low void ratio, its contact patch is markedly higher and the tread faces more rolling resistance as relatively large surface area require more energy for rolling over. The more surface area of tread is in contact with road, the more hysteresis (i.e. energy loss) is produced and more fuel is consumed to overcome high rolling resistance.

Comfort and Noise Comparison

WS90 is a louder tire comparatively due to its broad grooves. Its open voids offer more space for movement, reflection and resonation of wind particles leading to much noise while rolling along. Lesser traction due to lesser contact patch may make the rides little bit wobbly and less comfortable in comparison.

DM V2 produces lesser noise and offers more comfort than its competitor due to low void ratio of its tread. Narrow width and slanting arrangement of grooves not only allow limited space for wind collisions but also cancel out the effects of resonation of sound waves, leading to quieter rides. High contact patch with deep biting tread elements provide stable traction and comfortable driving experience on road.

Durability and tread wear

Like most winter tires, both of these tires do not come with any mileage warranty for tread wear. Moreover, as both of these tires come from Blizzak series from same manufacturer they employ similar tread composition characterizing dual compound  structure with first 55% being NanoPro Tech multicell compound with hydrophilic properties and enhanced traction capacity over snow while the remaining 45% features Bridgestone’s standard winter tire compound. After 55% wear a built in depth indicator points out that tread is reaching near its end.

Based on tread design we can say that DM V2 would wear out faster as more of its tread is in direct contact with surface and it faces more rolling resistance. On the other side high void ratio reduces rolling resistance and makes WS90 wear slower and last longer.

Price

DM V2 is more expensive than WS90 But it provides better grip over paved roads. However, WS90 have financial benefit of fuel efficiency and relatively longer tread life.
