It lowers your mpg
Yes. with larger tires the odometer will show less mileage than actually travelled.
It could make it better, but nost likely make it worse.
Yes.
Maybe, the manufacturer optimized the tire size to the vehicle, if your currently running larger than stock tires then you could be decreasing your mileage. Check the inside of your drivers side door for a placard with the correct tire size and inflation.
yes but it will so mess up the mileage.
How it rides, handles, fuel mileage and power are affected.
incorrect tire inflation
You can but it not a good swap. The 65 series tire will be 3.15% larger in overall diameter. It is never recommended to go over 3% difference. Your speedometer will read 58.1 at a true 60 mph. Performance and fuel mileage will be adversely effected.
Tires do not have oxygen sensors. They can have pressure sensors. The lack of pressure sensors would have no affect on fuel economy.
The size of the tyre affects top speed by altering the gearing. Assuming the engine has the power, a larger size wheel and tyre (diameter) will result in higher top speed.
Not quite. The 225/40 are 1 cm wider and 2.95cm larger diameter.
If the OEM size for the car is 205/55-16 then the 225/60-16 tires will NOT be a good choice as a replacement 60 series tires. They will be 7% larger in overall diameter and your handling, ride, fuel mileage, performance, and speedometer will be adversly effected. It is never recommended to go over or under 3%. If you wish to use a 60 series tire then you would need to install a set of 195/60-16 which wil be 1.35% larger in overall diameter and are acceptible.
