If the snow tires have a bigger diameter than the others, the odo and the speedo will read a bit low. If the snow tires have a smaller diameter the odo and speedo will read a bit high.
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.
Yes. with larger tires the odometer will show less mileage than actually travelled.
very minimal and not noticeable. tires only have a quarter to a half inch in height difference.
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.
Your tires reacting to a different speed and changing direction at the same time
wrong size tires.
Yes. If you put TALLER (width does not effect speed, only traction) tires on a vehicle it will increase your potential top speed, if you put SHORTER tires on a vehicle it will have a slower top speed. I say potential because if your vehicle does not have enough power, it will not be able to turn bigger tires at high speed. Also, a taller tire will lower your acceleration in most cases, and a shorter one will increase it, assuming you can maintain traction. Remember to have your speedometer calibrated if you get taller/shorter tires, otherwise it will not be accurate.
Jet Accu Speed Speedometer calibrator. It adjusts your speedometer for bigger tires or gear change. Only works on automatic transmissions.
Yes. Tires get hotter when speed is increased causing more wear. Example- Racing car tires wear out very quickly because of speed combined with high heat. Indy cars and cars used in Nascar may only get a few laps before needing changing. Addition: The effect isn't as drastic on passenger tires but speed does effect wear.
If the overall height is different, then yes.
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.
No because both cars are going the same speed. Changing the size of a tire effectively changes the gear ratio the car drives in. A larger tire will gear the car up and so it will have a higher top speed.
