So I did some digging online and read that I may need to change the gear size for my speedo, but I'm wondering if my issue is with the gauge or cable rather than size of gear. The original tires were 9.5x16.5s and I have 8.75x16.5s. Someone told me the 9.5s are slightly taller, but I was wondering if that slight of a tire size change could cause my speedo to be 8mph slow.
