Duraseal Technology after repairs
Posted by Michael from Dover, OH, US on April 27, 2009
I am wondering about the effectiveness of Duraseal after a puncture repair and or retread of the tire. Does the duraseal function as original after the retreading ? Also in the repair manual , it mentions removal of the liner, I am assuming that this is a permanent removal of the sealant and it cannot be replaced is this correct?
The manual also states that a NDT II electronic inspection machine is required, is this something most retread facilites currently have?
Our DuraSeal, self-sealing tires have been around for several years now. We say that DuraSeal will self seal tire punctures up to 1/4" in diameter. I assume you are asking about a puncture greater than 1/4" in diameter that does require a repair when the object is removed. The liner and the sealent material does is removed in the area of the repair so the tire looses its self-sealing properties in the repaired area. The rest of the tire will continue to have the self-sealing qualities after repair and after retreading. I can not speak for all retread facilities but, can tell you that any Goodyear Authorized Retreader is required to have an electronic inspection machine for nail hole detection.
