By ratio if you mean size, the answer is no unless the car comes from the factory with a different size rear tires than front tires like some sports cars. In that case you would have 2 tires the same size on the front and 2 tires another size on the rear. You should never ever run 2 different size tires on the same axle. Therefore you would never have a situation where you would have 3 tires one size and then 1 tire another size.
The new tires have to match what the automobile manufacturer requires for that vehicle.
yes
While it is good to use tires with the same tread and sizes, it is possible to use tires with different tread patterns, though you should be careful as the performance of the two tires may be different, causing your car to be unbalanced, endangering your passengers.
Depends what tires they are because different tires have different densities...
No, not less one of the tires is out of balance. But it is never, ever, a good idea to have two different size tires on the same axle. This is a big no-no.
Thousands of different car tires are made in America.
No, they can't fit on the same car.
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.
The driver could use different sized tires or reduce the amount of friction.
You can, but it isn't recommended. Idenctical tires, not merely tires from the same manufacturer, are preferred.Different tires, even from the same manufacturer, have differing tread patterns to achieve different purposes. Some tires are designed for rain performance, some for high-performance handling, and others for fuel efficiency. Installing different tires, and thus differing patterns, mean different handling, performance, and even fuel efficiency characteristics under varying road conditions. You get the best out of none of your tires when you mix-and-match.Ideally, all four wheels should have identical tires. If that's not possible, ensure that you have identical tires at least on the same axle (pairs on the front or the back).
Yes, just be sure all the tires are the same size and put winter tire on drive axils, never use different size tires on a 4x4 all four must be the same size, or you will damage transmission.Answeryes
rubber Rubber is used with many other things to make different tires, depending on what they will do, once on a car.
