Troubleshooting
Tyre failing to hold pressure after installation
Ensure the rim bead is clean and free of debris. Use a bead sealer if there is minor corrosion on the rim.
Noticeable vibration while driving on pavement
Check that the tyre is properly seated on the rim and confirm that the air pressure is set exactly to 10psi.
Excessive wear on one side of the tread
Have your quad or trailer wheel alignment checked, as uneven wear is typically a symptom of suspension or alignment issues.

Setup, Compatibility & Care
Before installation, ensure your existing wheel rims are compatible with the 18x9.50-8 sizing. Since these are tubeless tyres, it is highly recommended to use a professional tyre mounting machine to avoid damaging the bead during seating. Regularly inspect the tread for embedded sharp objects or stones, particularly after off-road use. If the trailer or quad will remain stationary for long periods, keep the tyres out of direct sunlight and maintain the 10psi pressure to prevent flat spots and dry rot. Always check the sidewall for any signs of cracking or bulges before embarking on a journey.
