Gume za sva godišnja doba

Gume za sva godišnja doba kombinuju osobine zimskih i ljetnih guma, pa su primjenjive tijekom cijele godine. Predstavljaju optimalan izbor za one koji malo koriste vozilo tijekom godine i ne izlažu ih ekstremnim vremenskim uslovima kao što su velike vrućine ili snježne padavine.

Gume za gospodarske mašine

Razlikujemo pune i šuplje pneumatike, u zavisnosti da li vertikalno opterećenje gume apsorbuje guma ili vazduh. Po vrsti primjene postoje pneumatici za utovarivače i za male radne mašine(bobcat).

PR(ply rating) vrijednost.

Određuje stepen mogućnosti opterećenja pneumatika. Što je PR vrijednost veća, guma je otpornija na spoljne utjecaje. U slučaju teških terena ili zahtjevnih uslova eksploatacije preporučljivo je kupiti gume sa većom PR vrijednosti.

Struktura gume

Po strukturi razlikujemo dvije vrste guma.

Dijagonalne gume su takva vrsta guma, gdje kordovi zatvaraju ugao od 45 stepeni u odnosu na rub gume. Između gazećeg sloja i bočnice pneumatika nalaze se jastučasti ulošci koji su napravljeni od rjeđih vlakana, formirajući prijelaz između bočnice i gazećeg sloja.

Kod radijalnih pneumatika se ove dvije funkcije razdvajaju i optimizirana je konfiguracija vlakana na radijalne sile. U slučaju radijalnih pneumatika kordovi su vertikalni u odnosu na uzdužnu osu pneumatika pa samim tim trpe dva puta veća opterećenja u poređenju sa dijagonalnim pneumaticima. Kord radijalnih penumatika se sastoji od upola manjeg broja vlakana nego kod dijagonalnih što proističe iz pravca primjene. Zid pneumatika je tanji, što doprinosi bržem hlađenju pneumatika kao i većoj otpornosti uticaju centrifugalne sile nastale pri velikim brzinama. Zahvaljujući krućoj strukturi, bolje je prianjanje na kolovoz. Takođe je smanjena pokretljivost gazećeg sloja što smanjuje otpor pri rotaciji. Prilikom nailaska na kamen, nastaju veća opterećenja na rastezanje, što doprinosi razdvajanju ili cijepanju slojeva pneumatika; radijalni pneumatici brže propadaju na neravnom kolovozu (kaldrmi) nego dijagonalni pneumatici.

Oznaka strukture pneumatika. Oznaka R označava radijalni pneumatik. Ostale mogućnosti: ukoliko je oznaka samo srednja crta (-) ili slovo D, to označava dijagonalni pneumatik.
