Slime Tire Sealants, Inflators & Repair Kits

A flat ends the ride. Slime tire sealant stops most tread punctures before you even know you have one, sealing holes up to 1/4" in tubeless ATV, UTV, mower and trailer tires so you can keep rolling.

At Witchdoctors, we carry the Slime lineup riders and shops rely on: tubeless tire sealant in 24 oz, 32 oz and 1-gallon sizes, tube sealant for dirt bikes, emergency sealant for highway vehicles, plus Slime tire inflators, plug kits and patch kits. Find the right formula for your tires below.

Why Riders Use Slime Tire Sealant

Off-road tires pick up thorns, nails, cactus spines and sharp rock all day. Slime goes inside the tire ahead of time and seals punctures as they happen.

  • Prevents flats on the trail: seals tread punctures up to 1/4" (6mm) in tubeless tires.
  • Fixes slow leaks: add it to a tire that keeps losing air from a small tread puncture.
  • Long-lasting: Slime's tubeless and tube sealants protect for up to 2 years.
  • Easy to install: inject through the valve stem with the included valve core tool.
  • Water clean-up: Slime cleans up with water.
  • Saves time and money: fewer trail-side repairs, fewer tow-outs, less downtime for work machines.

How Slime Tire Sealant Works

Slime is a fiber-packed liquid sealant. When the tire spins, it coats the inside of the tread. If something punctures the tread, escaping air pushes sealant into the hole, where the fibers bind together and plug it, usually before the tire loses much pressure.

Slime works on the tread area only. It won't fix sidewall cuts, bead leaks, damaged rims, faulty valves or gashes bigger than the rated size.

Tubeless Tire Sealant for ATVs and UTVs

Most ATV and UTV tires are tubeless, which makes Slime Prevent & Repair the go-to choice. Install it before you ride and it guards against tread punctures for up to 2 years. Buy the 24 oz bottle for a machine or two, the 32 oz bottle for bigger tires, or the 1-gallon jug with pump for a fleet, farm or shop.

Tube Sealant for Dirt Bikes and Tubed Tires

Tires with inner tubes need a different formula. Slime Tube Sealant goes inside the tube and seals tread punctures up to 1/8" in dirt bikes, bicycles, wheelbarrows and tubed mower tires. Don't use tubeless sealant in a tube, or tube sealant in a tubeless tire.

Emergency Sealant for Highway Vehicles

Slime Emergency Tire Sealant is made for cars, trucks, SUVs, RVs and trailers. It gets you to a tire shop after a tread puncture, but it's a temporary fix: have the tire repaired, or the sealant removed, within 3 days or 100 miles.

Slime Tire Inflators

Sealant plugs the hole; an inflator gets you back to the right pressure. The Slime Super Duty Pro Power Tire Inflator connects directly to a vehicle battery and has a clear LED digital gauge (0-99 psi), a bright LED light and a 33-ft hose that reaches every tire on a UTV, truck or trailer.

Slime Tire Plug and Patch Kits

For punctures that are too big for sealant, or tires you want to fix permanently, a plug or patch kit is the next step.

How to Install Slime in a Tubeless ATV or UTV Tire

  1. Park on level ground and let all the air out of the tire.
  2. Remove the valve core with the tool included with Slime.
  3. Shake the bottle well, attach the hose to the valve stem and squeeze in the amount listed on the bottle's chart for your tire size.
  4. Reinstall the valve core and inflate to your recommended tire pressure.
  5. Ride or spin the tire right away to spread the sealant across the inside of the tread.

Use the dosage chart on the bottle for your exact tire size. Too little sealant may not seal a puncture; too much adds weight.

When Slime Won't Work

  • Sidewall cuts or punctures outside the tread area
  • Bead leaks, bent or damaged rims and faulty valve stems
  • Punctures larger than 1/4" (tubeless) or 1/8" (tube sealant)
  • Off-road and mower formulas in tires driven over 45 mph

For these, use a plug kit, a patch or a new tire.
