Best Practices
– Any tire, no matter how well constructed, may fail when in use
because of punctures, impact damage, improper inflation,
overloading, or other conditions resulting from use, misuse
or neglect.
– High speed towing in hot conditions degrades tires significantly.
– Best practice. Do not exceed 60 mph while towing a trailer.
– Most ST trailer tires have a maximum speed rating of 65 mph.
– Load carrying capacity decreases as heat and stress generated by
higher speed increases.
– Time and the elements weaken a trailer tire.
– 3 to 5 years is the average life expectancy of a trailer tire,
regardless of mileage.
– It is estimated that in approximately three years, roughly
one-third of a tire's strength is gone.
– After three years, depending upon storage and conditions of
usage, consider replacing trailer tires even if they have tread
depth remaining.
– After five years, trailer tires should be replaced in all cases.
