Yes. with larger tires the odometer will show less mileage than actually travelled.
If the overall height is different, then yes.
yes by the same amout it throws off your speedo
Larger tires will affect the speedometer. There may not be a large difference in your application, but there will be a difference. You may be reading 45mph, and really be going 48mph. the worst problem will be in your odometer after a few thousand miles. your odometer will be WAY off once you have traveled a few K miles. I would suggest going to a local transmission shop to have your speedo re-calibrated for the larger tires. If you go much larger than that, check with your local mechanic on how well your transmission will be able to turn such a large tire. you may need to be re-geared.
It lowers your mpg
YesPutting larger diameter tires on any vehicle will affect the speedometer and odometer readings. If you know the revolutions per mile for the original tires and the larger tires, you could calculate the speed difference. If they are already on the vehicle, you can also drive down the highway, set the speed at 60 MPH and measure the time it takes to drive between mile markers. One mile at 60 MPH takes 60 seconds. If it is not 60 seconds between mile markers, the difference is the speedometer error. AnswerYour tires are 10% larger than the car thinks. Therefore, you travel 10% more than your car recognizes. This has two effects: Your actual speed is 10% MORE than what your speedometer is reflecting. (When your speedometer reads 60, you are actually traveling 66)10=11, 40=44, 100=110 etc.Your actual mileage is 10% MORE than what your odometer is reflecting. (When your odometer reads 100 miles, you have actually traveled 110)So when you see a cop doing a speed trap, remember to slow down accordingly.When you sell your car, don't forget to disclose that you have larger tires and that the odometer should read more miles than it does.
TS = OR * CTD / STD Where: TS = True Speed OR = Odometer Reading CTD = Diameter of the current tires on your car STD = Diameter of the Standard Tire for your car.
wrong size tires.
if the rear tires are turning the odometer does go up. but you can pull the drive shaft out and it will not matter the odometer will stay the same.
It could make it better, but nost likely make it worse.
First off I am assuming the larger tires and wheels fit with adequate clearance. The 15" tires are likely taller than the 14" tires, that means they have a larger circumference, thus a longer rolling distance. It will make the car sit slightly higher. Most likely the biggest difference will be that the speedometer and odometer will read incorrectly, I don't know just how much.
Kinda-sorta, but not really.Speedos are usually set to register a little high, as car manufacturers don't want the drivers to blame them for getting a speeding ticket - but that planned error doesn'taffect the odometer.But if you've change the tires or something which has thrown the speedo off, that change will also affect the odometer.
Putting larger tires on your car will give you higher top spee with less torque. However, changing the tire size will make your speedometer inaccurate.
