Question:
Will a st145/12r tire fit on a 5.30-12 rim?
asked by: Dave D
Helpful Expert Reply:
Since both a ST145/R12 size tire, like the Kenda Karrier S-Trail # AM10130, and a 5.30-12 size tire, like the Kenda K353 # AM10068, fit a 12 inch wheel, a ST145/R12 size tire can replace a 5.30-12 size tire.
Keep in mind that these tires do have slightly different diameters and widths though, so you will want to do some measuring to make sure that the ST145/R12 tire will fit on your trailer.
The 5.30-12 tire that you currently have has a section width of 5.3 inches and has a diameter of 21.9 inches. The ST145/R12 size tire that you are wanting to replace it with has a section width of 5.7 inches and has a diameter of 21.3 inches. Since the section width of the ST145/R12 tire is about 1/2 an inch wider you will want to make sure that you have enough clearance with the trailer frame as it sits about 1/4 of an inch closer. It shouldn't be a problem but it is always best practice to double check clearances.
