4in Spiky Wheel Tread Evaluation
The 4in Spiky Wheel Tread is designed to be very durable and last for several matches of play. Determining when to replace the tread is highly dependent on the use case of the wheel. If you notice flat spots or uneven wear, we recommend replacing your tread right away. For general use, replace once the wheel's diameter has decreased by 1/8in.
Traction Wheel Evaluation
Axial vs. Radial Wear
In this section, we will describe different features wear patterns as Axial or Radial. Here are some descriptions of what these terms mean on a REV ION Traction Wheel.
Radial - Describes features that occur radiating from the center of the wheel towards the tread
Axial - Describes features that occur side to side along the wheel’s axle
Wheel Rating Guide
Green Wheels - Okay to keep using this wheel because it is still in good shape. There is minor wear or damage to the tread but no signs of too much axial force or scrub.
Yellow Wheels - The affected wheel should be monitored closely because it is showing signs of wear that could lead to delamination of the tread. Please be sure to check the wheel again after your next match!
Red Wheels - Red Wheels need to be replaced right away and before the next match if possible. Delamination is very likely to occur with continued use beyond this state.
Green Wheels
Green wheels show early signs of wear that will eventually lead to the tread delaminating from the core of the wheel. When evaluating green wheels it is important to note that tread depth is something to be aware of, but it will not affect the rating of the wheel.
Green wheels have little to no radial separation (or peeling) of the tread. Also, the tread is still resilient enough to spring back quickly if it is stretched along the separation.
Small cuts or gouges in the wheels do not disqualify it from being rated as green. You will also see no axial separation on green wheels.
Sometimes looking at your wheel from the top down along the tread can help you identify radial separation easily. Green wheels will have straight borders since they have not had any axial separation yet.
Yellow Wheels
Yellow wheels show moderate signs of wear that will eventually lead to the tread delaminating from the core of the wheel. When evaluating yellow wheels it is important to note that tread depth is something to be aware of, but it will not affect the rating of the wheel. Even if a MAXSwerve Wheel has near-perfect tread grooves, if there is any axial separation from the core it should be classified as yellow.
Yellow wheels have some radial separation of the tread from the core as well as clear axial separation. The tread may be able to spring back still when moved, but it will remain separated from the core.
Axial Separation on a yellow wheel is noticeable but does not interfere with the forks of your module or create excess friction in your drivetrain.
When looking at the wheel from a top-down view, you can sometimes see axial separation on a yellow wheel along the edges. Also within the axial separation, you will not be able to see the core's support posts.
Red Wheels
Red wheels show serious signs of wear that will soon lead to the tread delaminating from the core of the wheel. When evaluating red wheels it is important to note that tread depth is something to be aware of, but it will not affect the rating of the wheel. Even if a REV ION Traction Wheel has near-perfect tread grooves, if there is a large amount axial separation from the core it should be classified as red.
Red wheels have major radial separation of the tread from the core as well as clear major axial separation. The tread may not be able to spring back when moved but regardless of how the tread behaves your team should replace this wheel.
Large gaps of both radial and axial separation on a red wheel may interfere with the forks of your module or create excess friction in your drivetrain as the tread expands.
When looking at the wheel from a top-down view, you will likely be able to see axial separation of the tread from the core of a red wheel. Within the axial separation, you will also be able to see at least one core support post (shown below)
