California98Civic, the difference is about 4.83% and the overall diameter is about ~1'' difference according to this table https://www.1010tires.com/Tools/Tire...0R13/185-60R15
The engine seems to respond quickly due to the light weight flywheel, the wheels are not super heavy, they are 10 spokes from 2003 Civic Si EP3. |
That site's calculation of "speed variance" does not make sense. A larger tire/wheel will produce a slower indicated speed, not faster. But also, when you look at manufacturers size and weight data for tires at tirerack.com, you see that apparently actual tire size varies significantly within a given official size category. And then there is the variation auto manufacturers are allowed by the regulators as far as how accurate the odometers are. The only way to know how far off your odometer is, is to measure with a GPS over a significant distance, say 25 or 100 miles or more, and compare the odo reading to the GPS. Do it several times, like on your regular commute or something. You can probably find a good wheel weight figure at wheelweights.net ...
