Can 225/70R16 tires fit on rims that have 225/70r14 tires on them?

I have 225/70r14 tires on my Ford ranger.

I just got some 225/70r16 tires of the same brand, Cooper, given to me.

Will they fit on the 225/70r14 rims or do I need to get rims to fit the 225/70r16.

The last number of a tire size is the diameter of wheel it will fit on. Since one is a -14 and one is a -16, they will not fit on the same wheel.

Nope.

You need 16 inch rims
