Nukeproof Mega Carbon Tyre Clearance: Keep the 290 Limit Visible
Nukeproof Mega Carbon tyre clearance needs the exact wheel platform and the actual tyre-and-rim combination. The 2023 MK4 manual’s 290 specification lists a maximum 2.5-inch tyre, while its general warning later describes the frame as accepting up to 2.6 inches. Keep that inconsistency visible. A larger general figure is not permission to disregard the more specific 290 entry.
Nukeproof Mega Carbon tyre clearance: Locate the model-specific statement
Printed page 36 identifies the Mega 290 Carbon as a 29-inch platform and gives 2.5 inches in its maximum-tyre row. The frame-features section on page 22 also gives 2.5 inches for 29-inch wheels. Those entries make the 290 question more specific than a search for the largest tyre mentioned anywhere in the document. Take both to a supplier when a proposed replacement differs from the original size.
Page 41’s broader 2.6-inch statement does not explain the difference or identify a revised 290 clearance. This article does not declare one page a corrected edition of another. Ask for applicable confirmation for the identified frame, and retain the conflicting source passages with that request. Do not translate an unresolved catalogue difference into a new maximum of your own.
Read the front and rear requirements separately
The warning page also lists fork examples: Fox 36 29-inch at 2.6 inches, RockShox ZEB at 2.8 inches and Domain at 2.8 inches. These are the examples printed in this 2023 manual, not a specification for every later fork bearing the same name. Identify the fork currently installed and its applicable instructions rather than treating an archived family label as universal guidance.
A fork clearance entry cannot enlarge the rear frame’s limit. Likewise, a tyre that appears to clear one part of the bicycle has not established clearance throughout the relevant assembly. Nukeproof expressly notes that some tyre-and-rim combinations can measure wider when fitted together. The nominal sidewall width is therefore not a complete measurement of the actual installation.
Make the replacement enquiry concrete
Provide the exact frame platform, both tyre markings, the actual rim identities and the fitted fork. Explain whether you are replacing worn tyres like for like or proposing a different model. Have the combination and its clearance assessed before use. The manual warns that rubbing can damage the frame; it does not supply a universal clearance gap or a pressure figure for every replacement.
The Nukeproof topic connects the wider range, and the brand introduction explains the families. For this tyre decision, separate the historical manufacturer entries from what is fitted now. Keep width, rim compatibility, condition and the applicable pressure information as distinct checks instead of expecting one larger catalogue number to settle all of them.
FAQ
What maximum appears in the 290 specification?
Page 36 gives 2.5 inches, consistent with the 29-inch entry in the frame-features section.
Can the 2.8-inch fork example approve that tyre at the rear?
No. A fork example does not replace the frame’s own requirement.
Does nominal width prove fitted clearance?
No. The manual warns that the particular tyre-and-rim combination can be wider when assembled.
