rim tire selection

I would like to consult you. I am looking for a tire for my new Peugeot 206 1.4 xr vehicle I bought. thanks in advance.

There are dimensions on the tire. In the form of 175 / 65r14. It refers to the rim size in inches after R. The original rim size of your vehicle is 175/65/14. If the rims are small, the cheeks are thick, it is normal for you. You can wear 195 / 45r16.
195 base size in mm
45 cheek size, 45% of 195 ie 87 mm
16 is the size of the rim. In inches

For some friends, this visual is not enough. They wear 205/40/17. Not recommended. This wide base and large rim negatively affect the vehicle's performance, comfort and fuel consumption.

The original size is 175/65/14 in 206. Generally this is not very strange, but I see sometimes they wear 13 rims, which makes the 206's that look really bad too. Maybe they could have worn 13 for sale. Spring torsion etc. If you want to play with parts, 14 is ideal.15,16,17 fine tuning does not taste like it is. Tire costs increase, when the diameter grows, some things should be compromised.
