How to use this calculator
- 1Prefer an exact manufacturer amount.
- 2Otherwise choose a general size band and service type.
- 3Enter reserve, bottle size and optional price.
Formula
total = base × service × reserve × tires
Complete bottles are rounded up after volume is calculated.
Calculation steps
- Normalize volume units.
- Apply service and reserve factors.
- Round to bottles and calculate leftover.
Worked example
Two gravel tires at 2 fl oz plus 10% reserve need about 130 ml.
Assumptions
- General bands are not universal.
- Top-up share is user selected.
- Product labels are accurate.
- Compatibility is checked separately.

Frequently asked questions
Which method is best?
Use the exact sealant or tire maker amount when available.
How much for a top-up?
Inspect the system and use the product interval; the percentage is deliberately user controlled.
What about inserts?
Enter an explicit reserve based on the insert and sealant maker guidance.
Does sealant retain the bead?
No. Compatibility and correct installation are separate requirements.
