Two tools for the tyre design office.
Each answers a question that normally costs weeks of testing to settle. Both run entirely on your own machine — no account, no network, nothing transmitted.
AIRR
Know a tyre's rolling resistance before you build it.
A rolling-resistance measurement costs money and weeks of scheduling, so most tread concepts are discarded on judgement rather than evidence. AIRR learns from the tyres you have already measured and puts a number — with its expected range — against a design you haven't.
Rolling resistance only — not wear, grip or noise. It narrows the field before rig testing; it does not replace the measurement.

The chosen sequence, drawn where it lives — around the tyre.
PATCH
Spread the impact energy across a band, instead of into one tone.
A tread with every block the same length puts all of its impact energy at a single frequency, and that tone is audible far beyond its share of the total level. PATCH derives the pitch set from the tyre size, then searches the arrangements of it for the order with the lowest tonal peak.
It ranks designs on how impact energy spreads across frequency. Absolute pass-by level needs a calibration table fitted to your own coast-by measurements.
Built for a design office, not a data centre.
Offline by design
No network connections of any kind. AIRR installs on an isolated design network; PATCH is a single HTML file that opens locally. Your geometry never leaves the building.
Reads your drawings
Both measure the pattern straight from a pitch image — any polarity, stepped or straight boundaries, dimension lines or none. No tracing, no scale to set.
Answers you can check
Every figure comes with its uncertainty or its assumptions stated, plus CSV export. Same inputs, same result, every time.
The rest is easier to show than to write down.
