You won't be sorry for going with the Michelin Defender LTX tires. Have used Michelin for more years than I care to remember, on cars, trucks, motorhomes and have NEVER had one failure. It's the only brand I buy, and insist my family does the same.
Funny how so many people blame the tire when they have a blowout. That poor tire may have been encountering everything the highway can throw at it for many, many thousands of miles, but if it should blow out, albiet years later, it's the manufacturer's fault. Never that piece of steel or 4x4 you hit many miles back, that weakened the tire. Always the manufacturer.
