Tire life?
My question is I have S637 tires that are 12/15 dated with lots of tread so what’s the usual life span on these tires? Also they list 110psi on the sidewall and I’m running 80psi. Should I air them ...

If the chart says 80spi for your actual tire load let er rip! They don't make weight/inflation charts for no reason.
I replaced 80psi "E" tires on my 32.5' Avion with "G" 110psi GY's. I ran those tires for several years at 85psi and had perfect tread wear. If I remember correctly the tires lowest inflation number was 85psi on the chart.
GY recommends when going up in load range to weight the tires and use the chart and add 5psi to the heaviest tire on each axle.
Don't buy the tire needs to be ran at the MAX "BS" because of tire scrub. That is proportional to the load.
Proper inflation will get you a cooler running tire, better stopping, better ride and better tread wear.
Charts are there for a reason, USE THEM !!!
When I ran Michelin XPS Ribs with about 10K on four of them I ran 65(placard inflation) and saw amount of outside edge wear. Increased to 71 and wear was even. Michelin CS also said along with decreased braking that over inflation can lead to impact damage.
All steel ply tires seem to run cooler that poly carcass tires. With RIBs, R250s(29' Cardinal) and S637(39' Bighorn) the trailer tires always ran cooler than the TV tires. Chris
