What size tires fit on 15-inch 6j rims?

[Leah]

15-inch 6j rims can accommodate tires with a width of 185mm, and the maximum width that can be used is 195mm. Here are the relevant details: 1. 15-inch rims: With a width of 7 inches, they are suitable for 205mm wide tires, with a maximum of 195mm. This size is generally used for track-oriented cars, offering higher performance limits. 2. Additional information: Avoid blindly increasing rim size. To enhance car performance by upsizing rims, while keeping the overall tire diameter unchanged, larger rims must be paired with wider and lower-profile tires. This reduces the car's lateral movement, improves stability, and allows for smoother cornering, making it feel as light as a dragonfly skimming the water.
