How we work
Measured, not claimed
Anyone can print a number on a website. The question worth asking a tire company is what happens when the number is inconvenient. These are the four rules we have committed to, and they are only worth anything for as long as we keep them.
- 01Every figure carries its conditionsA section width without its measuring rim is not a specification. A hardness without its temperature is not a specification. If we publish a number, the condition it was taken under travels with it.
- 02Unverified figures are flagged, not quietly roundedSome of what you see is still our working figure rather than something we have confirmed on our own equipment. Those rows say so. They will be replaced with measured values.. not adjusted toward them.
- 03We would rather leave a gap than fill itCamber and toe is the clearest example. Alignment is chassis-specific and we do not have data we would stand behind. We are not going to invent a starting point so this page looks more complete. Ask us and we will tell you what we have seen, and what we have not.
- 04Every set ships with its own measurementsA card in the box carrying that batch's measured figures against the published ones, with the deviation and the tolerance. Where a value falls outside tolerance, the batch does not ship.
What we do not publish
Two things, and it is worth being straight about both.
How the tire is made. Our tooling and the drawings behind it stay ours. Publishing your specification is transparency. Publishing your manufacturing package is handing a competitor a head start, and it would not make the tire under you any better.
Performance claims we cannot reproduce. No lap times, no grip figures, no percentage improvements over a rival. If we cannot put it on a machine and get the same answer twice, it is an opinion, and you can form your own for free.
Hold us to it
If something we publish does not match what you experience on track, tell us and we will either correct the page or explain why we disagree. That is the whole arrangement.
