A new RVer asked for advice on selecting rear tires for a 2018 Kia Sorento SX towing a 3,500 lb Nu Camp Tab 400, expressing confusion about load index ratings and whether all tires need to match. The original equipment tires were 101H, but the current set is 105V, which seemed to overheat and show higher PSI increases when towing.
Experienced members clarified that while it’s not strictly necessary for all tires to be identical, it’s highly recommended for AWD vehicles like the Sorento to use the same make and size on all wheels to avoid drivetrain issues. This ensures consistent diameter and prevents unnecessary wear on the AWD system. The discussion also clarified that the question was about the tow vehicle, not the trailer.
