Replacement Tires for 2004 Tracker Marine Trailer with F65-14ST Tires


My Tracker trailer currently has Tow Master F65-14ST tires on it. I understand that the equivalent tire size is now 205/65/14. I dont see those anywhere. Are most people using the next size up 205/75/14? What should I measure to make sure they will fit without a problem? Thank you for your assistance.

The direct replacement for the F65-14ST tire you mentioned would be a ST205/65-14, which is an uncommon size that we don't carry.

The closest equivalent we carry would be 205/75-14. The tire you currently have is 24.6 inches in diameter, and 7.4 inch section width. The ST205/75-14 is 26.3 inches in diameter and 7.8 inches wide which is about a 1/2 inch wider and 1.7 inches larger in diameter. This should be close enough to your original tire size to work fine. Going with a slightly larger tire size will place the top of the tire a little less than 7/8 of an inch closer to the underside of the fender. You'll want to leave yourself at least 3 inches of clearance between the two when the trailer is under load.

We have the 205/75-14 available in a bias-ply or a radial tire. The radial is available in a Load Range D with a 2,040 lb capacity at 65 psi, the part # AM10235 or a load range C, with a rating of 1925 lbs at 60 PSI which is part # AM10234.

I've linked you to our help article about trailer tires. The article contains a lot of information that you might find helpful.

For a bias-ply tire, we have a load range C, part # AM1ST86 or a load range B # AM1ST84 with a 1,430 lb capacity at 35 psi.
