Silverstone Wheel Ordering Guidelines. Help Us - Help You!

There are tens of thousands of different wheels available to fit machines in use today.
In order to help us help you get the wheel you need we need some information from you when you contact us. Here is a guideline to information you will need to consider:

1. Tire Information

Tire Size? _________
Radial or Bias Ply? ________
Tread style? __________
Tire application? _______________
Tire operating pressure? __________
Operating speed of the tire under load? ____________

You may be looking for a wheel or rim, but we need to know the tire size, radial or bias, tread style and application to figure out what kind or rim or wheel you need. Very important! The tire size and type dictates they style of rim or wheel that can be used to mount the tire.

Tire pressure and operating speed tells us more about the type of rim/wheel required for the machine and application. For example; there is a big difference between the kind of rim required for a 14.00-24 R1 tire used in a agricultural application or a 14.00-24 G2/L2 used on construction equipment or a 14.00R24 TG, or a 14.00R24 tire used on off the road truck or trailer application.

2. Rim style? How many pieces?

A. 1 piece rim/wheel. Could be one of many different rim profiles manufactured.
B. 2 piece (rim/wheel and side ring/lock rim combination)
C. 3 piece (rim/wheel, side flange and separate lock ring)
D. 4 piece (rim/wheel, (2) side flanges and separate lock ring)
E. 5 piece (rim/wheel, (2) side flanges, bead seat band, and separate lock ring, many also be driver key used)
F. Super Giant wheels used in very large mining trucks may be built with 6, 7 or 8 pieces.

3. Steel Stampings or labels?

This is very important. Are there any identifying part numbers or designations stamped or part number labels on the rim/wheel? These stampings can help us greatly in identifying the manufacturer, part number or a drawing, the style of the rim/wheel, material thickness or date and country of manufacture.

4. Rim or wheel?

Is the rim and open center with no disc? That would make it a “demountable” rim. If the rim has a disc welded to the rim then it would be a “wheel”.

5. How many bolt holes are in the disc?

How thick is the disc? Is the disc flat or is it formed in a particular shape?

6. Can you measure the disc offset

(where the disc is welded in the rim relative to the front of the wheel and the back of the wheel)? If it is a wheel (a rim with a disc welded to it) then count the holes. But, are the holes equally spaced around the disc or are they drilled in patterns (2 holes, space, 3 holes, space, etc…).

7. What is the bolt hole pattern?

Can you measure the bolt circle? Can you measure the pilot hole?

8. What is the diameter of the bolt holes?

Are the bolt holes drilled straight through with no chamfers or do they have chamfers machined into the holes? Are the chamfers on one side only or on both sides?

9. Where is the valve hole located on the rim?

Are there any valve guards welded on the rim/wheel?

10. Are they any other items welded to the rim/wheel such as flange reinforcements, driver pockets, special valve holders, driver blocks or other items not described here?

You can see from all the information we need that with all these items taken in aggregate, the number of wheel variations can number in the hundreds of thousands.

If all this seems like a foreign language to you, we have a document on our website that explains all this very easily and gives you some nice work sheets to record this information for when you contact us.
