Dupa cum stiti, am trecut de la jante de 15" echipate cu cauciucuri 195/65/R15 la jante de 17 echipate cu cauciucuri 215/45/R17.
Vitezometrul ma cam mintea si inainte, sunt curios in ce directie ma minte acum, cum influenteaza marimea jantei viteza afisata.
Si m-ar mai interesa cum poate fi calibrat, alexmirica povestea ceva pe un alt topic legat de etalonare prin GPS.. cum se poate realiza?

Este ceva ecuatie matematica pe site-ul asta ca sa calculezi eroarea.

10x pt informatii!
linkul lui WLF este cu adevarat Tyres Bible, drept pt care nu am avut rabdarea necesara de a citi totul pe acolo si nu am reusit sa gasesc exact ce ma interesa, iar linkul lui Alex_Alfa nu functioneaza, probabil foloseste un plug-in pe care eu nu il am instalat, caci nu mi se incarca. :?

Vezi ca pe link e un calculator cu doua dimensiuni de roti in paralel si cu niste sageti care vor duce catre eroare.

Pui rotzile standard intr-o parte si rotzile noi in cealalalta parte si iti va calcula ce eroare ai la 70 mph.

Merci WLF, de data asta am gasit!
Eroarea nu pare a fi foarte mare, "when your speedo reads 70mph, you're actually travelling at 68.99mph " si este in plus (indica viteza mai mare decat cea reala..)

Next: how can we fix this?
