Frequently asked questions
How do I check the fit?
Compare the complete tyre size with your existing tyre and check the rim, clearance and equipment requirements. If you are unsure, send us a photo of the size marking before ordering.
Does this tyre need an inner tube?
Yes. This is a tube-type tyre. Select a compatible inner tube with the valve arrangement required by your wheel.
Which inflation pressure should I use?
Follow the tyre sidewall and equipment manufacturer’s instructions. A pressure listed in the specifications does not override your tyre, rim or equipment requirements.
Is the tyre load the equipment user weight limit?
No. A tyre load rating describes the tyre. The equipment manufacturer’s user weight limit still applies.
