How it rides, handles, fuel mileage and power are affected.
Your transmission shifts according to the speed you are traviling. Different tire size rotate different speeds according to how big or small they are, small tire will rotate 2 times as a big tire rotates 1 so the ratio is 2to1 so if u have bigger tires u will travel further and faster than a smaller tire so it will affect when transmission shifts
No you do not. Bigger tires and wheels have nothing to do with it stopping.
Yes you can put bigger tires on your existing wheels up to a point. Talk to your local tire dealer and they can advise you on the biggest tires you can use.
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.
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.
for traction
Yes. Odometers don't measure the distance directly, they count the number of turns. Usually somewhere in the drive train, after the gear box. A bigger tire will have a bigger circumference. And bigger circumference means that you get a longer travelled distance for each turn.
ones bigger ones smaller
Yes.
Increasing tire size from the OEM tires will increase the stress load induced on the driveline. The planetary gears and carriers have to work harder than they were designed for and that creates a problem that leads to premature wear on planetary gears and on many other Automatic transmission components alike.
The speedometer in a car runs based off the speed of the transmission. The gears in the transmission spin at a known rate for the speed the vehicle is traveling at. The faster the gears spin the more the speedometer goes up. If a person replaces stock tires with larger tires, then the tires will spin slower, which will cause the speedometer to read at a value that is less than the actual speed.
