What is the difference between wheel hub 8j and 85j

(`▽′)The difference between wheel hubs 8j and 85j. What width tires can be used with 8j and 85j wheels?

When it comes to the difference between wheel hubs 8j and 8.5j, I believe many friends are still not very clear, so that in After purchasing the tires, I discovered they didn’t fit. So, today we will give you an answer as to how wide tires can be equipped with 8j and 8.5j wheels.

The difference between wheel hubs 8j and 8.5j is undoubtedly the width of the wheel hub, and the cross-sectional width range suitable for the tires is different. Of course, some wheel hub width signs are not expre ssed in the form of 8.5J, but 81/2, but the amount of information contained is the same.

What width tires can 8j and 8.5j wheels be equipped with?

8j wheels - can be adapted to tire widths in the range of 225-245, with 235 being the optimal tire width.

8.5j wheels - can be adapted to tire widths ranging from 235-255, with 245 being the optimal tire width.

As for which tire section width to choose, although the largest width tire can indeed bring better grip performance and lateral force, due to the increase in contact area, the friction coefficient is definitely relatively small. High, so it will have an impact on the car's fuel economy. Therefore, in order to have more balanced tire performance, it is best to choose the optimal tire width corresponding to the wheel hub.

The main difference between wheel hubs 8j and 8.5j is the width of the wheel hub and the range of tire cross-section width it adapts to. The following is an introduction to the specific differences:
First of all, my country's wheel hub specification codes are basically in line with international standards, in which the nominal width and nominal diameter are expre ssed in inches. The 8j wheel refers to an overall wheel with a rim height of 8 inches and a height code of j. It can be used with tires with a diameter of 18 inches and a width of 225/235/245mm. The 8.5j wheel hub means that the width of the wheel hub is 8.5 inches.
Therefore, when selecting or replacing wheels, it is very important to understand these specification differences, because they directly affect the choice of tires and the driving performance of the vehicle. Different wheel width and tire width combinations will have an impact on vehicle handling, stability and comfort.

The key role of wheels in automobile construction cannot be ignored, and their specifications have a significant impact on vehicle performance and appearance. Among them, 8j and 8.5j are two common specifications:


First of all, there is a difference in wheel hub width: 8j repre sents a wheel hub width of 8 inches, while 8.5j repre sents a width of 8.5 inches . This subtle difference directly determines the width range of tire selection.


Secondly, their compatibility with tire widths is different: 8j can adapt to tire widths of 225-245 mm, while 8.5j can match tires from 235 to 255 mm, which will Directly affects the vehicle's driving stability and handling performance.


There are also various surface treatment processes for wheel hubs, common ones include baking paint and electroplating. Electroplated wheels are subdivided into silver electroplating, water electroplating and pure electroplating. These different treatments not only significantly affect the appearance design of the wheel hub, but also have a significant impact on durability.


In general, the 8j and 8.5j specifications of wheels are different in details. Choosing the appropriate specifications is crucial to improving the overall performance and visual effects of the car.
