Can Load Range E Tires Be Replaced With Load Range F Tires

Question:
It is ok to replace 2021 Keystone Outback 341RD E speed rated with F rated tires?
asked by: Joseph B
Expert Reply:
Hi Joseph; based on the E and F rating that must be the load range of the tires. This is the same as the ply rating. Moving from E to F is alright to do, it will be a slightly higher capacity with a higher ply. I wouldn't jump more than a single rating or you may end up with a rough ride. Speed ratings are typically L, M, and N. The base speed rating on tires can be J or K which would be 65 mph but tires with this rating typically don't list it, it is implied if the other speed ratings are absent.
