I have put new avons on my car this last week and have noticed that my speedo is out by 7mph compared to my snooper +gps ,,i no that a cars speedo is a % on the + side to help prevent speeding and other tyre issues , but if my speedo says 60 gps says 53 ,,i changed tyres like for like being 215/45/17s only brand was diffrent, had pirelli,s on before and it was fine
Went back to tyre fitters and they tell me that fiat do not reccomend avons on the stilo 2.4 but could not say why ,but he did point to this being the reason why the speedo was so far out
So went home pulled out the owners handbook only to find he was right they reccomend pirelli,s /michelin/bridgestone/goodyear
It actually says "size only certified and admitted only if "the above are fitted
Has anyone noticed this much diffrence ,,,i suppose i should be glad speedo is not the opposite way
