Before You Buy
This is not the 120 TPI folding version. Match the 559 mm bead-seat diameter, confirm that your rim manufacturer approves a 4.0-inch tire, and check frame and fork clearance. Mounted width depends on the rim and setup. It is not a universal replacement for every tire labeled 26 x 3.0–5.0.
Installation and Included Contents
Sold individually: one tire, not a pair. Confirm a compatible tube and rim protection; no tube, sealant, tools or installation service is promised. Do not assume tubeless or hookless compatibility. Inspect the actual tire and rim pressure limits and follow the lower applicable limit. E-bike suitability depends on the actual bicycle fit and its load or speed requirements, not the category label alone.
Mechanic Compatibility Guide
Q: Which version is this? A: Origin8 Tsunami 26 x 4.0, rigid wire bead, 30 TPI, UPC 888571023938. This is not the folding 120 TPI version.
Q: What rim diameter is required? A: ISO 559 mm bead-seat diameter. The nominal 26-inch label alone does not prove fit.
Q: Does it fit all 26 x 3.0–5.0 applications? A: No. Check the rim manufacturer's approved tire-width range, actual mounted width, frame and fork clearance, and the bicycle's load or speed requirements.
Q: Is a rim-width range verified? A: No exact approved range is established here. Confirm with the tire and rim manufacturers before installation.
Q: Is it tubeless-ready or hookless-compatible? A: Do not assume either. The current store record marks tubeless compatibility false; explicit tire and rim approval is needed for alternative setups.
Q: What pressure should be used? A: Inspect the actual tire sidewall and rim limits, follow the lower applicable limit and select pressure for the complete setup.
Q: What is included? A: One tire. A compatible tube, rim protection, pump and suitable tire levers may be needed and are not promised with this listing.
Q: Does the E-Bike category certify a speed or load rating? A: No. Confirm the requirements of the actual bicycle.
