No!. It is very unsafe to mix tire and rim sizes.
Probably not. The rim may not clear the brakes.
Yes, as long as the 14" tire/wheel combination is the same diameter as the 15" you are removing.
You destroy the tire trying to stretch it around the rim.
NoNo
That means it is a Radial tire to fit on a 14 inch rim
No
No, unfortunately, the rim will not fit that tire. This is because these two tires require different sized rims. One of these needs a?æ16-inch rim while the other needs a 14 inch rim.
No. You will not get the tire on the rim without tearing it.
no 15" tire will not bead up
No, the R15 means that it is a radial tire and the 15 is the rim size. Never try to mount a tire and a rim that are different sizes.
Only if the bolt pattern is identical, and not generally a good practice.
