Not familiar with the Westlake brand, but will never again have any Chinese tires on my TT. I have Maxxis M8008 all around and about 3,500 miles on them. The pressures and temps are far more stable than any of the other three brands that I have had on it. [TowMax, Akuret and Hercules]
I now run the unit across the Cat scales the day before any trip and I'm 1,800 lbs under the CCC posted. I never run more than 10 gallons of water, but have a virtual hardware store of tools and extra parts onboard. Oh yes, two spares.
