First off you should not install tires that are not the correct size. But if you do, make sure the tires on each axle are both the same size. Both front tires same size, and both rear tires same size.

To determine the size of mountain bike tires you need for your bike, you should check the current tire size on your bike's tires. The size is usually printed on the sidewall of the tire. Common sizes for mountain bike tires are 26 inches, 27.5 inches, and 29 inches. Make sure to get tires that match the size of your current tires to ensure they fit properly on your bike.
If all four tires on an MTB bicycle are 26 by 2.10, they are the same size.
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.
If the tires are the same size then yes.
Yes tires and rims are correlated based on the size of the tires you are looking for. While you can interchange rims and tires as long as they are the same size you will need to ask your mechanic or repair service center if you have an unusual size rim.
