You can can China out of the equation with the well regarded Maxxis 8008 ST tires made in Thailand. Far cheaper solution than upgrading to 16." I replaced my Load Range D Chinese tires with LRE Maxxis tires the second season and now have about 12,000 trouble free miles on them.
Before all the "but can your wheels handle 80 psi" comments, you can run them at 70 psi and have more capacity than the old tires at 65 psi.
