I am replacing the stock Bridgestone Excedras on my 2013 Voyager with Michelin Commander II's. My research says they provide a better ride and traction while lasting twice as long. The rear doesn't come in the stock 170/70 size but does come in a 180/65. I know it will fit but was wondering has anyone put these tires on their Voyager and experienced any speedometer issues, i.e, reads fast or slow? I think the circumference between the two is similar but haven't been able to find that number for comparison.
