I just wonder what your insurance company would do if you crashed and they found out you were running a non motorcycle tire on your bike. We all know how they try to get out of paying a claim, I bet they would jump on this excuse not to pay. Then again, it could differ ny what company you have and how good their investigators are.
that question has arisen 1,000s of times, and the answer is the same.
They don't care, it has a TIRE mounted on the wheel, and that is all they care about. I have asked 3 agents this question, all gave me the same answer.
Care tires have been on HD motorcycles since the 30s or more. They cannot invalid your claim.
And, no Car tire yet, have ever been posted that it blew up and caused a bike to crash, at least not on this forum, nor on GoldwingDocs, and from what I have read, not on GL1800 Riders either.
only paranoid folks ask this type question, the rest of us just go ride and enjoy 3 to 5 times the mileage, and in the rain double or better traction for 1/3rd the cost or less.
