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.
No!. It is very unsafe to mix tire and rim sizes.
14 inch
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.
