- Valve type: This tube uses a Schrader valve, so the wheel must suit that valve format.
- Puncture protection need: The sealant is intended to help with punctures up to 1/8" (3 mm), so compare that limit with the kind of puncture protection you want.
- Fitment confidence: If you are replacing a tube, confirm the size and valve type before fitting.
What Else You May Need
