First you have to ensure that the tire physically fits to your car. Beneath the diameter of the rim, there are these characteristics:
- Number of bolts and diameter of hole circle. The hole circle is the (virtual) circle on which the holes for the bolts are located. This is usually given in the form 4x100 meaning "4 bolts, 100mm diameter"
- Diameter of the hub / center hole of the rim
- Rim offset - The offset of the contact surface between car an rim from the center of the wheel (to the outside is positive)
I found this:
Peugeot 107 Ka(-2008) Ka (2009-)
bolts x center hole 4x100 4x108 4x98
center hole 54.1 63.4 58.1
offset 39 36 35
If these values are correct, rims are interchangeable between none of these cars.
But there is more: The lower limit of rim size is defined e.g. by the brakes. If they are too large, they may not fit inside a 13" rim. I haven't found any 13" rims for the peugeot 107 (but didn't search very much), so may be, they don't fit due to this constraint.
If a rim fits to your car, have a look at the wheel dimension and ensure it has enough clearance.
Finally, a different circumference leads do a different speed reading. Make sure your car isn't faster than it displays, and not too much slower.
