Question:
Hey guys, Ive got a Big Tex CH70-16 dual axle car hauler w/ 15inch steel wheels and Im wondering if these parts will fit: Grease Cap - RG04-040 Center Cap - AM90113 One grease cap just rattled off and I wouldnt mind covering both the grease cap and making the wheels look a little nicer.

To determine if the grease cap # RG04-040 will fit on your trailer you will need to measure the inner diameter of your trailer hub's pilot hole. This will need to be measured as accurately as possible so it's best to use a digital caliper like # PTW80157. The # RG04-040 will fit a pilot hole that is just slightly smaller than 1.99 inches. The hub's pilot hole needs to be a bit smaller than the cap so that the cap fits snug. If that cap is not a fit, I've linked our selection of grease caps for you to choose the correct size.
Since you told me you have a hub bore of 3.665 inches on your rims the correct chrome center cap to fit is # 319EZ. This cap is fit for 3.19 inch hub bores which is slightly smaller than yours so it will fit and not have any play in it. The center cap # AM90113 will not fit your 15 inch rims. It's made to fit 12 and 13 inch rims. To find the correct center cap you will need to measure the center bore of your rims. I have linked this selection for you as well.
