Komparativna analiza karakteristika pneumatika putničkih vozila u Srbiji

Abstract

U radu su predstavljeni rezultati istraživanja stanja i karakteristika pneumatika koji se voze u Srbiji. Prikupljeni su podaci o pohabanosti dezena, dimenzijama, starosti, marki, tipu više od 700 pneumatika kao i podaci o vozilima na kojima su montirani. Osnovni zaključak je da je stanje pneumatika dobro, odnosno znatno bolje nego što je sanje voznog parka u Srbiji. Prosečna izmerena dubina šare protektora bila je oko 5 mm, a prosečna starost kontrolisanih pneumatika oko 3 godine. Značajan deo pregledanih vozila bio je opremljen zimskim pneumaticima. Prva istraživanja (Beograd, novembar 2009) o korišćenju zimskih dala su dobre rezultate sa oko 25% automobila opremljenih sa takvim gumama. Tokom drugog istraživanja (Beograd, juli 2010) uočen je pad od oko 5%. U Užicu, gde su sprovedena istraživanja u novembru 2010 godine utvrđeno je da se taj procenat popeo na 50%. Struktura i starost voznog parka u Srbiji su ocenjeni kao nezadovoljavajući. Sa sadašnjim stepenom obnove voznog parka, takvo stanje će se veoma polako menjati na bolje što će uticati i na strukturu i karakteristike pneumatika koje će vozači u Srbiji kupovati u narednim godinama.

The paper presents the results of the condition and characteristics of tires that are in use in Serbia. Data on wear patterns, sizes, ages, brand, type, more than 700 tire and vehicle information to which they are mounted. Data about tread depth, dimensions, tire age, brand and type of more then 700 tested tires were gathered, as well as information about vehicles to which they are mounted on. Primary conclusion on tire condition is positive, notably better then than the Serbian vehicle fleet condition. Average age of tires was around three years and measured tread depth about 5 mm. A significant part of the examined vehicles was equipped with winter tires. First survey (Belgrade, November 2009) for winter tire usage had good showings with around 25% cars equipped with such tires. During the second survey (Belgrade, July 2010) decline of about 5% was found. In Užice, where survey was conducted in November of 2010 it was found that the percentage of winter tires increased up to 50%. Structure and age of the passenger cars fleet in Serbia have been assessed as unsatisfactory. With the current level of fleet renewal such a situation will be very slowly changing for the better and that will affect both the structure and characteristics of tires that will be bought in Serbia in the coming years. With the current level of renewal of the fleet, such situation will be very slowly changed for the better that will affect the structure and characteristics of tires that that will be purchased in the coming years in Serbia.
