Can I widen from 195 to 205 without changing the rims?

It is possible to widen from 195 to 205 without changing the rims because there are no national regulations prohibiting the use of tires one size larger. However, the size of the rims must not be altered and must match the original factory specifications. If the rim size is changed and discovered by traffic police, you may face penalties requiring mandatory restoration. Generally, 195 tires are paired with 15-inch rims, while 205 tires are paired with 16-inch rims. A 15-inch rim can accommodate up to a 205 tire, but it is still recommended to use a 16-inch rim. The numbers 195 and 205 represent the tire's cross-sectional width: 195 indicates a tire width of 195mm, and 205 indicates a tire width of 205mm.
