What Tires do you Recommend I Upgrade to From the Factory B78-13ST on my Pop-Up Camper

Question:

My pop up has stock b78-13st tires. Would st205/75d14 tires fit as replacements?

The standard tire you have is similar to the Loadstar ST185/80D13 Bias Trailer Tire part # AM1ST79 is 24.4" in diameter and is 7.2" wide.

The Loadstar ST205/75D14 Bias Trailer Tire with 14" White Wheel part # AM3S440 is "26.3 in diameter and 7.8" wide. If you have the room for the additional tire and still have 1-2" between the tire and frame as well as 2-3" of clearance from the wheel to wheel well you will be in good shape. This one in particular has the 5 on 4.5" bolt pattern white wheel.

Keep in mind you only need to add half of the difference since it is split front to back and side to side. This means you will add 1" to your current height and check it then add about 3/8" to the width and check.
