Find your formula
The right Dilloz. The right amount.
Choose your ride. We’ll find your formula and fill amount.
For air-filled tires, with or without inner tubes. Use a listed stock tire or enter its measurements.
For a listed tire, use the same amount of Red, Blue or Green.
For golf carts, mobility devices and other equipment, use the cart and mobility tire guide.

The exact chart is still available. For an unlisted pneumatic PEV tire, reload this page and measure the mounted tire when the finder is ready. Open the full tire chart.

Before you fill
How do I measure my tire?
Choose “Measure my tire.” With the tire mounted and inflated, measure its full height from the bottom tread to the top. Then measure its width at the widest point. Enter both in the same units. Measure the tire, not the rim.
Already have sealant inside?
For a Onewheel, start with 4 oz of Armor-Dilloz. For a bike, scooter or EUC, start with half the recommended amount. Add more if needed.
See the installation steps for adding sealant and dealing with a puncture.
Sealant plugs punctures; it cannot repair torn sidewalls or structural damage. Stop riding if the tire will not hold safe pressure.
Already have sealant inside?
Start with less than the full empty-tire amount.
- For a Onewheel, start with 4 oz of Armor-Dilloz.
- For bikes, scooters and EUCs, start with half the recommended amount. Add more if needed.
Check your measurements
Use the outside of the mounted, inflated tire, not the rim size.
- Measure the inflated tire from the bottom tread to the top, then measure its width at the widest point.
- Check the units and decimal point. If the size is still outside the calculator, use instructions for that exact tire; do not change the measurements to force a result.
Check the top speed
Use the fastest speed your ride can reach, including its fastest riding mode.
- Check the device specification, including any modifications.
- Enter that speed and select mph or km/h. Choose Red at 30 mph or less, Blue above 30 mph.
Does this match your tire?
The model and fitted tire must match the chart row.
- Check the model and size printed on the tire.
- Changed the tire or cannot find a match? Choose “Measure my tire” and enter its outside diameter and width.
Check the fitted tire
The listed amount is the same for Red, Blue and Green.
- Use the listed amount when your model and tire match.
- If you have a different tire, enter its mounted outside diameter and width.
Check the speed you entered
Choose Blue above 30 mph. Green is the value option, especially for larger tires.
- Check that the number and mph or km/h setting are correct.
- Use the same listed tire amount with any of the three formulas. Sealant does not change the tire or vehicle speed rating.
Check your EUC tire
Choose Red at 30 mph or less, Blue above 30 mph. Green is the value option.
- Check your wheel’s top speed and the tire fitted to it.
- Use a matching chart row, or measure the mounted tire’s outside diameter and width.
Choose your type of ride
Use the category that matches the ride in front of you.
- Select a bike, e-bike, Onewheel, scooter, EUC or other personal electric vehicle above.
- For golf carts, mobility devices and other equipment, use the cart and mobility tire guide linked at the top.
This finder is for smaller tires
It does not calculate amounts for cars, highway motorcycles, e-motos, highway trailers or street-legal NEVs.
- Follow the tire and vehicle maker’s instructions for sealant and puncture repairs.
- For golf carts and mobility devices, use the cart and mobility tire guide linked at the top.
The calculator could not load
Try refreshing the page, or use the dosing chart.
- Find the row that matches your model and fitted tire. The amount is the same for all three formulas.
- If your tire is not listed, try the calculator again when it loads. Do not borrow an amount from a different tire.
Check your answers
One of the details needs another look.
- Choose your ride and confirm whether sealant is already inside.
- Select the matching tire, or enter its outside diameter, width and your ride’s top speed.
This tire is outside the calculator
We do not have a calculated amount for the setup you entered.
- Check your device selection, tire measurements and units.
- If those are correct, use the tire and sealant instructions for your exact setup; do not choose a different device to force a result.
