Nobody is more knowledgeable than Roger Marble when it comes to RV tires. A retired tire engineer for more than 40 years, Roger’s experience with tires includes working with Indy car winners (too many names to mention). He’s also performed “autopsies” on tires to determine the true cause of “failure”. How does Roger feel about blowouts? Is there such a thing as China Bombs? What’s the one thing he would tell his friend before buying a set of tires? Find out the answers and more in this conversation with Alan Warren, The RV Wingman.
