Frequently asked questions
How do I check the size?
Compare the full size marking on your existing tyre, including any ETRTO marking, with this listing. The nominal diameter alone does not establish a fit. Send us a photo of the marking and wheel if you need help.
Is this a tubeless tyre?
No. This is a tube-type tyre and needs a compatible inner tube. Confirm the tube size and valve arrangement for your wheel.
Is the tyre load rating the equipment user weight limit?
No. The listed load is a tyre specification. The equipment manufacturer’s user weight limit still applies.
Which inflation pressure should I use?
Check the tyre sidewall and the equipment manufacturer’s instructions. The supplier-listed pressure does not override the requirements of your tyre, rim or equipment.
