ST205/75-D14 Trailer Tire on a 14" Wheel with a 5 on 4-1/2" Bolt Pattern.
- Load Range: C
- Capacity: 1760 lbs at 50 psi.
Replaces F78-14 Tire.
Note: Bias Ply Trailer Tires can only be used with Bias Ply Tires. Do not replace a Radial Tire with a Bias Ply Tire unless you are replacing all the tires on the trailer.
Note: Most trailer tires that are smaller than 15" and have 5 bolts, have a 5 on 4-1/2" bolt pattern.
How to Measure Bolt Pattern
The first number in the bolt pattern is the number of bolt holes. The second number is the diameter of the circle the holes sit on. To determine the diameter on wheels with an even number of bolt holes, measure center-to-center on bolt holes directly across from each other on the circle (Example: 8 on 6-1/2 would mean 8 bolt holes with 6-1/2" center-to-center diameter). When the number of bolt holes is odd, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from it on the circle (Example: 5 on 4-1/2 would mean 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolts).
AND / OR
The distance between the center of one bolt hole on the wheel to the center of the bolt hole right next to it will also help determine the bolt pattern.
- If D = 2-5/8" then the bolt pattern is a 5 on 4-1/2
- If D = 2-3/4" then the bolt pattern is a 5 on 4-3/4
- If D = 3" then the bolt pattern is a 5 on 5
- If D = 3-1/4" then the bolt pattern is a 5 on 5-1/2
