Tire Pressure Monitoring Systems

A lot depends on driving habit....first do you speed, that means going over 60 mph with ST s...do you fill your tires to max cold tp and keep them there...do you protect them from uv.... what is date on tire?... do you stop regular and check tire temps with hand and laser.....along with bearings...is any one tire more than 85% of max weight? I bought one when I bought trailer and is worth it to me for not have to get on knees and check all pressures daily....plus does let you know temps and what each tire is doing....good luck...I can now say this, trail express lasted 2 yrs and 7 mo in service....age 2 yr 9 mo...2 started cracking near bead on trailer right side....they were cared for and never abused.....however who knows what the delivery man did when he pulled them 600 miles for deliver.....we all know they went over 60 then LOL...and who knows what kind of curb action they had during that time....but they had 8000 miles on them when retired and the guy at tire shop was grinning...as they all had nibs on them and they looked new...so I am sure they are winding up on a trailer somewhere....the true life and care of a tire is never truly known...unless you build it at the factory and put it on your trailer good luck
