Ne govorim o vi?ini profila ampak vi?ini gume - boka Verjemi da se dr?ijo ve? kot dobro, stestirano, opisal sem zgolj primer v klanec gor, ko je te?a avta zadaj, z res polno vode na cesti, pa ?e to pod obrati in je parkrat cuknilo (sistem kompenziral) pri vo?nji narvnost. No pa tudi stara cesta je ?e kanalasta v iber....na avtocesti pod istimi pogoji no way da bi se to zgodilo. Pri mojih konkretno je sedaj razlika 205/16 proti 225/18. sicer pa bi lahko bil pameten le da bi ob istih pogojih nataknil ?e 16 in videl razliko Navsezadnje pa imam celo malo prav http://www.smartmotorist.com/driving-guide...quaplaning.html The 3 main factors that contribute to hydroplaning: Vehicle speed. As speed increases, wet traction is considerably reduced. Since hydroplaning can result in a complete loss of traction and vehicle control, you should always reduce speed, paying attention to the traffic around you. Tire treads depth. As your tires become worn, their ability to resist hydroplaning is reduced. Water depth. The deeper the water, the sooner you will lose traction, although even thin water layers can cause a loss of traction, including at low speeds. Tu sem mislil na vi?ino gume - je isto, vi?ja ko je bolje odvaja preko kanalov in globina vode na cesti je v bistvu to pri 5cm vode na cesti je 18 zalita isto kot 16 pri 8cm na primer
