Our Snowmachine club, here in Alaska, has been using a BR400+ to groom and maintain about 150 mi. of snowmachine trails for the last 3 seasons. It seems we are haveing to replace about 5 intermediate tires each year. They have all been foam filled. Tires have been everything from some trailer tires to Fall Line,and Bambardier. They all began to blister on the sidewall then soon after start to come apart. Is this just one of those maintaintance things we need to budget for or should we be doing something to get longer life from these tires?
Any help will be much appreciated.
