215 tires mess up speedometer?
I just bought my jeep about a month ago and the guy just recently installed some 215/70r16's on my jeep. When im on the highway and going 120kph i usually pass all the cars infront of me with my girlfirends accord. But with this jeep im going 120 and everyone is passing me. Just wondering if smaller tires like that can throw of the speedometer and make it seem like im going faster when im not. Also can having smaller tires than recommended in the manual hurt anything on my jeep? Thanks
