Ok, I dont keep track, tire size doesnt matter for fuel use. It just seems I need to fill up more than before.
Tire size does in fact change the gas mileage you'll get on a vehicle. How could it not?
It changes the apparent gas mileage, not so much the actual gas mileage.
Again, its been years since the tire change.
A bigger tire has an increased circumference. For every rotation, the vehicle travels further. But it still registers the same on your dash, because the mileage shown is based on the number of wheel rotations. When it says you've traveled 1 mile, you may actually have traveled 1.2 miles. You may think you re getting, for example, 18 miles per gallon, when you are actually getting 22 miles per gallon.
I suggest you find a measured mile, drive it at exactly 60 MPH with a stop watch running, and see how many seconds you are off a minute when you complete the distance. Don't start from a standing start, enter the mile at 60 MPH. It should take you exactly one minute. Bigger tires throw out your speedometer reading as well as your odometer reading.
Fuck yall, do you read? I know what bigger tires do and have had them for years. That has nothing to do with using more gas lately! Fuck do you even have gps? Fucking watch!
Bigger tires on your drive axle will certainly up you better gas mileage .lLittle slower off the line though I used to put high profile tires on all of my pre computer cars You can do it on computer cars to but only slightly bigger profile or it will throw the computer off. C'mon man
Its been years with the same size tires man.
