Replacement 145/12 Trailer Tires and Wheel for Rockwood Freedom Pop Up  

Question:

Current tires are secura ds618 st145r12 with 5 bolt 4-1/2inch spacing. Just want to make sure this is the right one. Everything looks right except when I measure the rim it is 13inch diameter and this says 12. Perhaps Im measuring wrong? If not, which wheel should I order. Thanks

Helpful Expert Reply:

Wheel diameter is not measured using the overall diameter. It is actually the diameter inside where the tire sits. You have 12 inch wheels; the tire size also indicates this. Tire and wheel combo # AM35354 will fit but you will want the tire construction type and load range to be the same for all of the tires on the trailer. If you are replacing all of them then it isn't an issue provided all of the news ones are the same type and load range. But if you are just replacing 1 tire then it will need to be the same construction type (either bias ply or radial) and the same load range as the others.

Tire and wheel combo # AM35354 comes with a radial tire, load range D. We have several combos in the 145/12 size with 5 on 4-1/2 wheels. I have included a link to them for you.
