What are the wheel specifications for the Mondeo?

The 18-inch wheel model for the Mondeo is 235/45R18. Here, 235 represents the tire's section width of 235 millimeters, 45 indicates the aspect ratio (the percentage of the tire's section height divided by its width), R stands for radial tire, and 18 denotes the rim diameter of 18 inches. The new Mondeo uses aluminum alloy wheels for the following reasons: The new Mondeo employs aluminum alloy wheels, which have gained increasing popularity among private car owners due to their aesthetic appeal, safety, and comfort. Maintenance methods for aluminum alloy wheels: When the wheel temperature is high, allow it to cool naturally before cleaning. Never use cold water for cleaning, as this can damage the aluminum alloy wheel and even deform the brake disc, affecting braking performance. Additionally, using cleaning agents on hot wheels can cause chemical reactions on the surface, leading to loss of luster and reduced aesthetics. For stubborn tar stains on wheels, try using a brush if regular cleaners are ineffective. A home remedy for removing tar: Apply medicinal "Huoluo Oil" for surprisingly effective results—worth a try. In humid environments, clean the wheels frequently to prevent salt corrosion on the aluminum surface. If necessary, apply wax after cleaning to maintain the wheel's shine.
The original wheel specs for my Mondeo are 5×108 bolt pattern, 63.4mm center bore, with an offset between 45 to 55. When buying new wheels, be careful not to get the wrong center bore size—my friend once overlooked this when ordering wheels online and had to return them because they didn’t fit. Common wheel widths are 7.5J to 8J, and the tire size depends on the configuration, with the sport version typically starting at 17 inches. Choosing the wrong offset is the most troublesome during modifications, as the wheels can easily rub against the fenders, causing noise from the chassis while driving. I usually have the mechanic check the wheel bolt torque during seasonal maintenance, since loose bolts can lead to serious issues. Wheel parameters for different model years of the Mondeo might have slight adjustments, so it’s best to check the manual after purchasing to confirm.
With over a decade of modification experience, I can tell you the core specs for Mondeo wheels are straightforward: 5×108 bolt pattern, and the center bore must be 63.4mm to match the factory hub. Don't randomly change the wheel's J value—switching from the stock 7.5J to 8J is relatively safe, but anything wider requires suspension adjustments. Based on my tests, the ET value should stay within 45 to 55; beyond that range, you'll definitely scrape the fender liners at full lock. Last year, I helped a fellow enthusiast pick 19-inch forged wheels and specifically chose an ET52 offset, which perfectly cleared the brake calipers. Remember, the wheel's stamped parameters on the back are the most reliable—give them a clean during car washes for accuracy, far better than online searches.
