Seeing an opportunity to expand his business, he purchased a retreading mold for passenger and truck tires. Later, due to the poor quality of casings available during the early 1970’s Bert got out of passenger retreading. He did, however, continue retreading truck tires. Today McGriff Treading Company, Inc. ranks among the top 5 truck tire retreaders in the United States. Bert’s business philosophy is the same today as it was in 1948 – be fair, work hard, provide excellent customer service, and do your best no matter what the job. After all, you never know when “someone is watching”.
