Nitro PROLINX Tire Mousse: Installation & Tuning Guide
Tokyomods Tire Setup
Nitro PROLINX Adjustable Tire Mousse
Nuetech Nitro PROLINX is a four-piece airless tire mousse set for off-road dirt bikes. Keep three LINX full length and cut the fourth to tune how the tire feels on the bike.
View the tuning chartOff-road use only. No street or highway use. Do not exceed 75 mph. Higher speeds can cause premature wear, damage, or failure.
Firm at the rim. Softer at the tread.
PROLINX uses nitrogen-energized material that compresses near the rim and stays more compliant beneath the tread. This gives the sidewalls support while letting the tread flex over uneven ground.
The mousse supports the tire without an inflated inner tube. Choose a firmer or softer setup by adjusting the length of the fourth LINX.
What’s included
- Four Nitro PROLINX sections in the selected size
- Silicone-based cooling gel
- Printed installation and tuning instructions
Choose the right PROLINX size
Check the exact tire brand, model, and size in the Nuetech fitment guide before ordering. Tires with the same sidewall size can have different internal volumes. Confirm the match with Nuetech if the guide does not list it.
Installation & tuning guide
Before you mount
- Confirm tire fitment. Check your tire’s exact brand, model, and size in the Nuetech fitment guide. Tires with the same marked size can have different internal volumes. If the guide doesn’t confirm a PROLINX match, check with Nuetech before mounting.
- Use a properly fitting, functioning rim lock. It’s required to prevent tire slip.
- Keep the lubricant inside the tire. Check used tires for holes and seal them before mounting. Tape over any unused rim holes. Use the full tube of supplied silicone-based lubricant; do not use tire mounting paste.
- Review the illustrated instructions supplied with the kit. Watch Nuetech’s mousse mounting demo for general mounting technique. If you lack the proper tools or aren’t comfortable mounting a mousse, have a qualified shop install it.
1. Lubricate the inside crown
Squeeze the entire tube of supplied lubricant in a thick bead along the inside crown of the tire, directly under the tread. The lubricant spreads as you ride.
2. Insert three full LINX
Seat three uncut LINX inside the tire. Push their adjoining ends firmly together so there is just one gap to measure.
3. Measure the gap
Measure the opening between the exposed LINX ends at its narrowest point.
- With a tape measure: Measure straight across the gap at the inside edge of the LINX.
- With the fourth LINX: Lay it alongside the tire. Line up its end with one end of the gap, then mark where it aligns with the other end. The thin dotted marks are 1 inch apart.
4. Calculate and cut the fourth LINX
Choose the feel you want and use the adjustment for your wheel. PROLINX is airless; the psi values describe approximate ride feel.
| Setup | PSI feel | Front | Rear |
|---|---|---|---|
| Firm | 13–14 | +5 in. | +3 in. |
| Standard | 11–12 | +4 in. | +1 in. |
| Soft | 9–10 | +3 in. | −1 in. |
| Extra soft | 6–8 | +2 in. | −3 in. |
Start with the measured gap. Add inches for a plus (+) value or subtract inches for a minus (−) value. The result is the total length of the fourth LINX after cutting.
For an 8-inch gap, a firm front is 8 + 5 = 13 inches. A soft rear is 8 − 1 = 7 inches.
Cut the fourth LINX to that length with a large knife or fine-tooth hacksaw. Soapy water on the blade helps it cut smoothly.
Ultra-low feel for hard enduro: Nuetech’s ultra-low setup uses a fourth LINX 5 inches shorter than the measured gap. Allow a full 10 minutes of riding for the LINX to elongate and space out.
5. Seat the fourth LINX and mount the tire
Fit the cut LINX into the tire and mount it using standard mousse technique. Center the rim lock under one of the three full LINX. If a long fourth LINX is hard to seat, use the layout in Step 5 of the supplied instructions to press the raised ends into the tire.
Break-in, maintenance & storage
- Let the feel settle. Tire construction can change the feel by 2–3 psi, and it can take 2–3 heat cycles to settle. After break-in, add or remove mousse material as needed to fine-tune the feel.
- Inspect and re-lubricate. Re-lube promptly if lubricant leaks from the tire or rim. After high-speed use on hard off-road surfaces, remove, inspect, and re-lubricate the LINX after each day’s use.
- Watch for softening. Service life varies with speed, temperature, riding intensity, and terrain. Re-stuff or replace the mousse as its feel drops. If a tire feels too soft or unstable, slow to a controlled speed, stop safely, and inspect the mousse before riding again.
- Store on a stand. Keep both wheels off the ground when the bike is parked for an extended period to help prevent flat spots.
