Fitment

Sizes and pressures

Every dimension names the rim it was measured on and the pressure it was measured at. A section width without its measuring rim is not a specification, it is a number somebody liked.

Rows marked not verified are our working figures and have not been confirmed on a measuring rim we would publish. They will be replaced with measured values, not adjusted toward them.

Pressure

The baselines above are cold, dry starting points on the stated rim. They are not recommendations. Surface temperature, ambient, your style and how many runs the tire has already taken move the number more than anything we could print.

The moulded maximum of 340 kPa is a structural limit for the casing. It has nothing to do with the pressure you should run.

Camber and toe

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.

There is no dealer network to search yet. Until there is, the routes are a container against a season, a warehouse order the week before an event, or the waitlist.
