The letter “J” means a tyre bead profile. This is the marking used to define the wheel collar profile you should never ignore. Wheel collars and tyres must be compatible.

What does 7.5 J mean on wheels?

The wheels width is usually written beside the flange shape marking – e.g: 7j, 7.5j, 8.0j. The width of the wheel is basically the area shown on the photo above and it is measured in inches. In other words, the bigger the number, the “thicker” your wheels are.

What does 6.5 J mean on a rim?

The first half (15) is your wheel diameter, simple enough, while the second half (the 6.5J) is the wheel width. By width we mean the section between the mounting flanges on the wheel.

What does ET43 mean?

What is 7J wheel size?

The rim labelling indicates the width in the first place as well. In 7J x 17 H2 ET38, 5x112 LK it is 7 inches. Now you have to know that a rim of this width fits on a tyre with a width of 195 to 225 mm. 205 up to 215 mm are ideal.

What is the PCD of a wheel?

Pitch Circle Diameter On any trailer wheel assembly or rim, the Pitch Circle Diameter (PCD) is the diameter of the circle which passes through the centre of all the wheel bolts or wheel rim holes. The center of every bolt hole lies along the edge of the pitch circle and are evenly spaced.

What is 7J rim width?

The rim labelling indicates the width in the first place as well. In 7J x 17 H2 ET38, 5x112 LK it is 7 inches. Now you have to know that a rim of this width fits on a tyre with a width of 195 to 225 mm.

What does PCD mean?

Pitch Circle Diameter The Pitch Circle Diameter (PCD) is the diameter of the circle which passes through the centre of all the studs, wheel bolts or wheel rim holes. The easiest way calculate the PCD is as follows: 1) Measure the distance S between two adjacent studs from the centre of each hole.

What does 8.5 J mean on wheels?

Typically, the alloy wheel size conforms to the following format: 20 x 8.5J. The first number, in this instance 20, is the wheel diameter. The second part, 8.5J, is the wheel width.

Can you put 225 tires on 245 rims?

Re: 225 tyre on a 245 rim? No. They are completely wrong. The width is unacceptably small for the standard 9 rims.

What speed rating is R?

Tires with a maximum speed capability higher than 300 km/h (186 mph), require a ZR in the size designation .Tire Speed Rating Chart.SPEED SYMBOLSP15094Q160100R170106S18011225 more rows

How do you read a rim size?

Locate the stamped size on the back of the hub on the rim. This is the assigned measured size of the rim, and it is broken into three sizes: diameter, width and bolt pattern. For example, a 14 by 6 by 4.5 reading on the rim indicates that the diameter of the rim is 14 inches, and it will accommodate most 14-inch tires.

What does PCD 100 mean?

100 is the simplest. So lets say you have an alloy with 4×100 PCD. It means it has four holes and the distance between one bolt hole and the one opposite to it is 100 mm. It simple means the circumference on which all 5 holes are drilled, it has a diameter of 114 mm. Same way 6 bolt wheel PCD is measured.

What does PCD stand for?

Pitch Circle Diameter Measuring a PCD On any trailer wheel assembly or rim, the Pitch Circle Diameter (PCD) is the diameter of the circle which passes through the centre of all the wheel bolts or wheel rim holes. The center of every bolt hole lies along the edge of the pitch circle and are evenly spaced.

What does it mean when a wheel is offset?

Wheel offset is simply the distance between the wheels hub-mounting surface and its center plane. Positive offset means the hub-mounting surface is closer to the wheels outboard side. Conversely, negative offset means its closer to the inboard side.

Are offset wheels bad?

If the offset is negative you will get more aggressive strain in return. It will help in increasing the steering wheel back with kick along with placing additional stress on the vehicle suspension. It will greatly affect the wheel rub which will damage the flange located in the inner part.

What does PCD mean in jail?

PCD is pre-trial court diversion. This is diversion before the arraignment so there is no filing against you
