So I am just checking to make sure my tires are good. Currently running toyo open country at2. The size reads as follows P265/70r17. Side wall it's "standard load" stamped on it. Sidewalk also indicates max load of 2535lbs. I have a 6200lbs 2axle trailer. My question is, are these tires safe to tow with? Or should I be looking to get new tires?
