Important Note
All tires under 47 mm that are not explicitly listed on this page are considered use at your own risk and are not officially approved.
Tires over 47 mm can be used observing the maximum pressure of 3.5 bar.
Important: If different values apply to the tire (specified on the tire) and the rim (3.5 bar), the lower value applies.
Tire clearances: 28 mm & 30 mm rim width
Our rims with 28 mm & 30 mm inner rim width (CH 50 BASIC GX, CH 40 BASIC GX from 2.26, CH 60 PRO GX, CH 45 PRO GX 30 mm hookless inner rim width) are consistently designed for the use of wide gravel and allroad tires and offer maximum stability, shape retention, and safety in off-road use.
Recommended tire width
The rims are ideally suited for tire widths of 45 mm or more. In this range, the wide rim base delivers its design advantages in terms of tire support, driving stability, and cornering control.
Official ETRTO approval
According to the ETRTO standard, an official approval applies to a 28 mm inner rim width for tire widths of 47 mm or greater.
