I had been wondering what people did to calibrate the odo specifically on civics. I'll have to check my numbers now. I just replaced my 175 70 R 13s Prime Wells with a set of LRR Michelin Defenders 175 65 R 14 with aluminum rims from an 04 Civic hybrid.

Old were about 917 rev/mile
New are rated 905 rev/mile

wich gives a 1.31% difference

I always just use the stock calibration on my scan gauge for its numbers however my fuel econ numbers come from the stock odometer versus gallons pumped with no correction and no scangauge data. Perhaps I should do some analysis on my new and old setups to see if any big adjustments are in the cards for me. I still have the old tires so it would be easy. A 5.5% bump would be huge even if it is only an arbitrary number at that point with no actual bearing on consumption.
