How to Determine Bolt Pattern of 5 Lug Trailer Wheel


Currently have ST205/75/R14 - 5 lug tires on my 2014 Keystone Bullet. Is that the same as 5 on 4-1/2inch bolt pattern?


Expert Reply:

The 5 on 4-1/2 inch bolt pattern is the most popular 5 bolt lug pattern found on trailer wheels. There's an easy way to measure and be sure though. You need to measure from the center of one lug to the center of the lug nearest to it.

If the distance is:
2-5/8" - the bolt pattern is 5 on 4-1/2
2-3/4" - the bolt pattern is 5 on 4-3/4
3" - the bolt pattern is 5 on 5
3-1/4" - the bolt pattern is 5 on 5-1/2

The part # AC14R45SM you referenced has a 5 on 4-1/2 inch bolt pattern.

Does anyone know what the bolt pattern is on 2002 Coachmen Lite 28BH 5th wheel? It’s 6 lug.

It's probably 6 on 5-1/2" as that's really the only 6 lug bolt pattern that's common for trailer tires. Here is a link to our selection of tire/wheel combos that use the 6 on 5-1/2" bolt pattern for you to check out. Just make sure that you have the same size and load range that you currently have on your 5th wheel.
