Product Description
CJM Industries Tire Section Width Measurement Tool
This is not an NASA official tool. CJM Industries & It's Not Stock, LLC are not associated with NASA.
Our adjustable tool is used to check your section width at home, or trackside to ensure it meets regulations for your class.
We built this tool to combine all sizes from the rulebook into one product. The thumbscrew can be removed to slide the left arm to each size. The sizes are engraved in the slot and become visible as the tool is adjusted to the desired width.
Each tool is machined out of durable high density plastic that is easy to clean and wont chip or crack. A brass threaded insert is embedded into the tool to stand up to repeated size changes. The prongs on each end extend 30mm forward.
This tool extends to measure the following sizes:
- 226
- 257
- 266
- 282
- 300
- 315
Dimensional accuracy is +/- 1mm.
