Q: Do I need special cement for these tire repair patches? A: Yes, REMA TIP TOP recommends using their Special Blue Cement (vulcanizing cement) along with proper carbide cutters for surface preparation to achieve a permanent, chemical bond that meets industry repair standards. The vulcanizing cement creates a molecular bond between the patch and tire, ensuring the repair withstands the heat, pressure, and flexing that occurs during normal driving conditions for a lasting, professional-quality fix.

Q: Can these patches be used on sidewall damage? A: No, the REM-A-4.5 is designed specifically for crown and tread area repairs only. Sidewall damage requires different repair methods or tire replacement per industry safety standards. The sidewall flexes significantly more than the tread during driving, and damage in this area compromises the structural integrity of the tire in ways that cannot be safely repaired with standard patch units.
