What size tires can be fitted on 7.5j rims?

[SanJulia]

7.5j rims can be fitted with tires of specifications 215/45R17 and 225/55R17. Each J value has a recommended tire width. During the rim modification process, many issues may arise. For example, if the original rim is 6JX15 inches and the original tire is 195/65/15, and you see a rim with a width of 8JX17 inches, the standard tire for this modification should be 235/45/17. The introduction to tire aspect ratio and the impact of rim modification are as follows: Introduction to tire aspect ratio: In the entire process of rim modification, the tire aspect ratio is also an important piece of data. The tire aspect ratio refers to the ratio of the height from the rim to the tread and the maximum measured width of the tire's cross-section, expressed as a percentage, i.e., the height as a percentage of the width. Impact of modified rims: If the ET value of the modified rim remains unchanged while the J value increases, the rim will protrude outward on both sides. For example, if the original rim is 7J and is modified to 9J, the rim will protrude outward on both sides.
