G416 Tires

I know this is a 2 year old post, but the info is still valid and many do research on this site, so FWIW. The tires you are referring to are Goodyear G614 G rated tires which are speed rated to 75 MPH. The thing with these is that unlike the stock ST tires which normally are speed rated at 65 MPH and maximum inflation pressure of 80 PSI, the G614's have a rating of 3750 lbs carrying capacity at 110 PSI. If you chose to use these tires, and they are very good if your actual weight is 17,000 lbs or less and the individual wheel weights are in the 3,200-3,300 lbs range, make sure your WHEELS can take the 110 PSI pressure.  If you weigh more than 17,000 lbs and your individual wheel weights are more than 3500 lbs. I suggest moving up to an H rated tire, which may necessitate a change to 17.5 inch wheels.  I have a 2017 Durango Gold 381REF and I weigh 16,400 loaded to full time. My heaviest wheel is 3,440 so even though I already have G614's, I am going to upgrade the wheels and tires to Goodyear G114's which are H rated @ 75 MPH. Those tires are pretty much bullet proof. The 614's are fine tires as long as you don't overload them. I personally keep my speed down to 60-65 MPH and have a tire pressure monitoring system.
