On our 2012 Tundra with 213,000+ miles on the odometer, I am on my third set. FWIW. I have been running them at 40 psi on the highway, but air them up to 50 when we go somewhere off road with a lot of rocks. I have never had a problem, but my wife has ruined two over the years while driving on rough backcountry "roads" that are not regularly maintained.
