They are still only rated at 3042 each. G614's are rated up to 34 something. But they require wheels that can handle 110PSI to achieve that rating. If a person needs more than 3042 each they would be wise to upgrade to 17.5 inch wheels and tires with upwords of 4000 pounds load rating each. My fifth wheel has a GVWR of 15,500 lbs. The G614's have a dual load rating at 3415 lbs at 110 psi. They cost about $320 each. For five of them that's about $1800 mounted and balanced. Going up to 17.5 will cost about $3500 for tire and wheels. Is it worth the added costs?
