Larger tires increase traction, reduce drivablity and increase noise inside the car.
Mostly they look neat
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.
for traction
ones bigger ones smaller
Yes.
definatley.
Yes, the tires will ruin your gas mileage overall. Bigger tires weigh more and they're harder to rotate on the vehicle even though they gain greater traction.
You recalibrate it because bigger tires mean different speeds... for example, lets say your car had 14 inch tires... and your speedometer is saying that you are going 50, if you add 20 inch tires which is 6 inches bigger, you might be going around 60-70. No need to get a speeding ticket. Bigger tires cover more road then smaller tires, for example for ever 1 turn from a 20 inch tire is like 1 and ahalf turns from a 14 inch... Hope Ive helped you understand why :)
Yes, they do.
GP stands for General Purpose They had tires so they could be operated on roads.
The purpose of an air compressor is to air up tires. This can be bike tires but also car tires. Because it is a small model, it takes some time to fill a car tire, but it works.
SUV tires do cost more than car tires. There is more material used in the bigger SUV tires. Keep an eye out in the newspaper, sometimes you can find a sale on tires at places like Big O Tires.
