Trailer Wheel Measurements Video

The closest modern tire size to a 7.00-15 tire is a 225-75-15 like the #AM10256 tire you mentioned. Typically, a 225/75-15 tire will measure about 8-3/4 to 9 inches wide by around 28-1/2 inches in diameter. We offer the same size in a Load Range E…

The Karrier ST175/80R13 Radial Trailer Tire with 13" Galvanized Wheel item #AM31994 are not balanced nor do they need to be.

To measure the width of a trailer wheel you will measure from where the tire beads will seat on the wheel. That will be from the inside of the inner wheel flange to the inside of the outer wheel flange, not from edge to edge of the wheel. To…

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13…

The pilot diameter on a wheel, like the one with part #AM30620, is the diameter of the bigger hole that is directly in the middle of the wheel. The pilot hole diameter of the wheel for the part I just measured is 2.84". I have attached a…

The wheel and tire combos we sell are not balanced at the factory. When the tire is mounted to the wheel, the high (heavy) spot on the wheel is matched to the low (light) spot on the tire, which leaves the wheel and tire somewhat balanced. You may…

First, thank you for your many purchases from us here at etrailer, including the Kenda Karrier tires #AM31994. Trailer tires that we sell come from the distributor already mounted to the rims. These do NOT get a full dynamic balance the way new…

The bolt pattern of 5 on 5 inch that there are 5 studs and the distance across the bolt circle is 5 inches. Most likely you have the more common 5 on 4-1/2 inch bolt pattern like what the wheel of the #AM20537 has instead. I attached a help article…

A larger tire size on your trailer in and of itself does not offer any advantages unless your existing tires are under-rated for their application, which would be unlikely in a stock tire. The overall diameter of a ST225/75/15 trailer tire is…

You need to measure the center hole of the wheel you have and then check out the link I attached which has all of the trailer wheel center caps we offer. You will need to select the center hole diameter that you have that matches the pilot size…

Going by the colors that you mentioned, it sounds like you have the typical set-up, green wire for right turn and brake, white wire for ground, yellow wire for left turn and brake, brown with green wire for right side running lights, and brown with…

It is likely that the red wire on your old lights is the turn signal/brake light wire, and the black wire is the running light wire. That would make the white wire the ground. You can verify this by testing the wires using a circuit tester such as…
