My friend has Westlake tires on his rig and hasn't had any issues with the tires in over 3 years now and his rig is about 10,000 lbs loaded
We have Westlake tires on our 18,000 lbs. loaded rig and haven't had any issues so far and there is about 4000 miles on the tires now. I do keep all 6 of them at 80 cold pressure.
Glad your trip is going well.
