Size 185/70-14 is not a common trailer tire size. Unless it has ST in front of the size it is a passenger vehicle tire and should not be used on a trailer. ST stands for special trailer. The smallest 14 inch trailer tire size is ST205/75-14.

For a radial tire and wheel combo in this size with a 5 on 4-1/2 bolt pattern I recommend # AM32161. This set up is rated for 2200 pounds at 75 psi. I have included a link to a video review of this tire and wheel combo for you.

the P185 / 70R14 fits the trailer if the 205 / 75R14 you are talking about is 1" taller it will rub the inside fender well

@MichaelH When the trailer is under load, you'll want an absolute minimum of 3 inches between the fender and the top of the tire, with 1 inch of clearance between the inner sidewall and the trailer frame. If a 1 inch taller tire wouldn't provide that, you'll need to go down to a 13 inch tire/wheel.

The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6-1/2 inch whereas the 225/75-15 fits widths that are 5 inch to 6 inch. The 205 is 27.1 inches tall and the 225 is 28.4…

Your math is correct in your trailer weight load example. If a fully-loaded tandem axle trailer weighs 4000-lbs then each of the 4 tires will bear 1/4th of that load, or 1000-lbs. In this case a tire rated for 1300-lbs would provide a good safety…
