What would you suggest as a ratio? the majority of my driving is local and highway.
Thanks.

depends what gearbox you have, auto, six speed, five speed, as the ratios are different
for example a 6 speed has similar rpm's at 100kph as an auto even though the stock diff ratio for a 6 speed is 3.07 and the auto is 3.73
and as pointed out, probably the speedo gear wasn't upgraded with the increased tyre size so you maybe travelling further than whats indicated on the odometer
