Are ceva daca se pune pe o masina de 1480kg niste cauciucuri cu indice de greutate 90/91 (suporta 600-615kg) in loc de unele 94 xl (extra load - suporta 670kg) ?

Asta nu inseamna ca fiecare cauciuc poate suporta 600 kg ? Adica masa masinii impartita la 4, ar rezulta o valoare de 370 kg/cauciuc (sau pe acolo, tinand cont de repartitia greutatii, sa zicem)...

da, greutatea e pe cauciuc, deci teoretic ar merge  (masina are 50-50 repartitia greutatii  )

QUOTE (florin83 @ Apr 22 2008, 10:39 AM)  da, greutatea e pe cauciuc, deci teoretic ar merge (masina are 50-50 repartitia greutatii )Parca greutate indicate la cauciuc se refere la greutate suportate maxima la viteza maxima admisa de cauciuc. Deci chiar pot sa depastesti greutate indicata, cu conditia ca nu mergi cu o viteza mare. E un trade-off. Cred ca are legatura cu caldura generate din cauza frecare / deformare de un cauciuc cu o viteza respectiva si o sarcina respectiva. Si, inca ceva, la viteze mari forta pe cauciucuri e mai mare decat greutate masinei, ca apare si downforce din cauza aer-flow. Poate mai stie cineva mai exact cum e.. -------------------- Black heart scarring darker still

Florine, cred ca iti faci prea multe griji cu greutatea asta...
Totul e sa fii atent sa umfi/dezumfli cauciucurile in raport cu incarcarea masinii si gata. Esenta este sa nu dai voie talonului sa se deformeze prea mult in mers (cauciucuri moi cu incarcarea masinii mare). Asta produce foarte multa caldura in cauciuc (explozie) si poate rupe si cordajul. In rest, daca e prea umflat are aderenta mai proasta si confort redus. Incadreaza-te in valorile presionale inscrise pe cauciuc si raporteaza-le la incarcarea masinii. Daca ai grija de astea, sunt convins ca nu vor fi probleme. -------------------- You only need two tools in life: WD-40 and "Duck" Tape.
For everything that doesn't move and it should, use WD-40. For everything that shouldn't move and it does, use the duct tape. |

ok, mersi de raspunsuri..
cauciucurile originale ale masinii (205/55/16) au indice 91, deci cred ca e ok
