Trailer tires on the truck?

   / Trailer tires on the truck? #11  
Trailer tires don't flex in their sidewalls like truck or car tires. They have very rigid sidewalls, so much so that plenty, if not most blowouts/ trailer tire failures are a result of under-inflation. This is often a result of visual trailer tire inspection, which is unable to verify inflation pressure at a glance, due to the sidewall not showing evidence of under-inflation because of it's rigid sidewall; unlike radials tires which will show a bulged out sidewall profile when a radial is under-inflated.Tractor trailer drivers hit their trailer tires with big tire irons to listen to the sound they make to know if a trailer tire is problematic. This is one way they use to quickly check their tires before driving.
Do NOT run any trailer rated tire on anything that is NOT a trailer The other reason why trailers have stiff sidewalls is many trailers for recreational users sit for long periods of no use every year, which would destroy the sidewall, and consequently the tire, if conventional tires were used.
