What is the corresponding tire size for a 5.5j rim?
2 Answers
The 'j' number in rims represents the width of the wheel rim in inches, with 5.5j being slightly narrower than 6j. Below is some relevant information about rims: 1. Introduction: The rim is the rotating part of the wheel that connects the tire's inner contour to the wheel hub via spokes, i.e., the metal component at the center that supports the tire and mounts onto the axle. It is also known as the wheel, wheel rim, or hubcap. Rims come in various types based on diameter, width, manufacturing method, and material. 2. Rim Types: Rims are also called wheel rims. Depending on the characteristics and requirements of different vehicle models, the surface treatment processes for rims vary, mainly categorized into painting and plating. For standard vehicle models, rims are less focused on appearance, with good heat dissipation being a basic requirement. The process typically involves painting, where the rim is first sprayed and then baked, offering a cost-effective solution with vibrant colors and long-lasting durability. Even when the vehicle is scrapped, the rim's color remains unchanged.
When I was changing rims, I researched the J-value issue. 5.5J refers to a rim width of 5.5 inches. The most suitable tire width falls between 175-195 millimeters, with 185 being the most common golden match. I remember helping a friend fit tires for his old Sylphy - the factory setup was 5.5J with 185/65R15 tires, and the steering felt exceptionally smooth. Within this range, the tire sidewall can perfectly fit the rim edge, providing better cornering support. However, you need to be careful with 195-width tires as the rim edge can barely hold the tire sidewall, making it prone to skidding in rainy conditions.
