The noise on roads/tar, gets generated by a lot of variables, including rolling friction, surface textures creating different tones/frequencies of sound waves, and then there’s in-groove resonance. Note: Snow to snow contact generated better results compared to snow to rubber. All of these features help in grabbing the snow particles, lodging them in, and making contact with it. Their outer circumferential grooves have “snow vices” in them, and their tread blocks are embedded with in-groove notches and numerous siping. It’s not related to handling and braking efficacy, as most folks think.Īnd so although both of these tires lack, when you compare them to dedicated winter tires, they are still above-average in mild snowy conditions. It only tells you that the tires with those symbols (on sidewalls) have 10% better acceleration capabilities, (on snowy roads) compared to average all season tires. Winter TractionĪlthough both tires aren’t 3 peak mountain snowflake (3PMSF) rated, they are both still pretty great. Moreover, the tire also makes proper sidewall lugs, unlike the TerrainContact A/T. They are equipped with notches, thicker siping, and their outer margins are serrated. ![]() ![]() These lugs have sharp in-groove notches, rectilinear sipes, off-set edges and saw-tooth biters facing the shoulders.Īnd together, they form 3 circumferential grooves in the middle.įurthermore, the shoulder lugs are sitting on a continuous running rib, (which is mostly seen with wear, as the image shows). The tread structure has 2 fat ribs in the middle containing a single block design, repeating itself longitudinally. ![]() Bridgestone Dueler AT Revo 3 features similar packed up shoulders, when compared to its counterpart.
