Tires and Odometers and Gas Mileage

Post by Fkyx » Thu Sep 03, 2015 4:49 am

Okay so I'm not here to bring up the topic of whether taller tires give better gas mileage or whatever.

Here's what I'm wondering, and I'm having trouble wrapping my head around it.

Let's say I'm running taller tires than stock, and I haven't done any adjustments to the odometer or anything like that.

If I'm calculating 25MPG from the odometer reading, am I actually getting more than that, or less than that?

more. you're going faster, further on the taller tires. I always use a site, tacomatirecalculator for the mph but I never thought about the MPG being affected. It is.

Yes, taller tires will cover more ground than your odometer measured, so gas mileage will be better than calculated from the odometer.
