## Questions & Answers

**Q: Will this work in tubed tires?**
A: Yes, the Ultraseal Extreme is a better version of Ultraseal for that application than our Bulletproof or Commercial Grades. It is specifically designed to be used in tubeless and tube-type tires. Thanks for the inquiry -- Gempler's Technical Department

**Q: What is the suggested amount used per tire?**
A: It depends upon the size of the tire. Ultraseal has a formula used to calculate the dosage amounts. The bigger the tire, the more Ultraseal it takes to coat the inside of the tire. Dosage is on the product label, or contact us and we can help you find what you need. Thanks for your inquiry - Gempler's Technical Department

**Q: will this stuff work with tractor tires that are filled with liquid for weight?**
A: Ultraseal will not work in tires that already have some sort of liquid ballast in them. While not used as ballast, Ultraseal must be the only thing inside the tire, other than air, of course. Thanks for the inquiry. - Gempler's Technical Department

**Q: Does this interfere with the tire pressure sensor system?**
A: No
