Trailer tire issues?
Leaving tuesday for 2900 mile move. Trailer is 7k and I have 1200 on tongue and 7300 on back axles. I know trailer is over loaded but didn't have choice. Trailer is brand new and tires are rated at 18...

Ok lets try to get this all sorted out
you have an 8.5x20 enclosed trailer by Mirage
it weighs 3000# dry and has a 7000# GVWR
it has 'c' rated tires that have a max load rating of 1870#@50 psi
Currently as loaded trailer weighs 8500# (trailer is 1500# over GVWR)
GVWR is MAX Weight for trailer......weight carried by axles PLUS tongue weight
Currently you have 7300# on trailer axles (total of both axles)
Axles are probably rated at 3500# each (7300# on 7000#...300# over total axle capacity but are axles carrying equal loads.....maybe rear axle is 500# heavier than front etc.
Currently you have 'C' tires with 1870# ea/max (3740# total for each axle---7480# total for both axles)
Tires inflated to 50# each........you have 180# total reserve capacity IF both axles/tires are equally loaded up. Over weight if one axle is carrying more weight than other...typically the rear axle will be heaviest
So ............
Your trailer is OVERLOADED by 1500#
Your trailer axles are OVERLOADED by at least 300#...possibly more depending on trailer loading
Your trailer tires are VERY CLOSE to max load rating .....more likely rear are OVER due to trailer loading
Your trailer tires are 'C' rated and most likely the cheapest tires mfg. could use and still meet weight ratings
You are going to make this trip...that is a given
Air tires up first thing in AM before driving .....50#
Check/adjust tire pressures EACH AM prior to traveling .....50#
(don't go adjusting psi during travel---adjust cold each AM)
150 miles for fueling........
Buy an Infrared Temp Gun
Check tire temps at each stop (fuel and/or rest)
Aim laser light between 2nd set of threads on each tire and 8" distance (same spot/same distance each tire)
Track tire temps..........note each position (F/R front/right, R/R rear/right ETC.) You are looking for trends (rear running hotter then front, right side running hotter then left side etc)
Sunny side tires WILL be hotter then tires on opposite side...
What you are looking for is a tire that keeps increasing in temp or is constantly running hotter then other
Also us IR Gun to check trailer hub temps...same spot/same distance....same idea about 'trends'
Good luck.........drive safe and AWARE.
Check tires (PSI/Temps and WEAR), check axle hubs
Stay alert to what is going on.
