Solution for Lowering Car Hauler

Question:

Ive got a PJ trailers B5 buggy hauler with 5200lb Dexter axles. The problem Im having is the I dont have the clearance needed to fit it in my garage while loaded.. and taking all the air out of the tires of the truck is very time consuming. It currently has 225/75/15 tires and I was thinking a smaller tire and possibly using a small lowering block under the axles.. my question is does anyone make a smaller tire that keeps the higher load range at least 2500lbs per tire ? And will a 1 or 2inch block add too much leverage on the suspension when braking?

We do have smaller tires available that will fit your existing 15 inch wheels, however they will not feature the load capacity you are needing for your car hauler. For example, a 205/75R15 tire like # C20851D has a maximum load of 2,150 pounds per tire. This tire will have an overall diameter/height of 27.1 inches compared to the 28.4 inch diameter of your current set. Keep in mind though that a change in tire size will only lower (or raise) the trailer by half the difference in diameter, which would be just 0.65 inches in your case. This may not be enough of a difference for the trailer to fit in your garage.

Going smaller from there, if you were to decide to change the wheels as well, would only decrease further in capacities. Since you are needing the higher capacity tires, going down in size is not going to be your best option.

If the leaf springs on your trailer happen to be currently mounted above the axles, you might be able to use an Over-Under Conversion Kit like # K71-384-00 for 3 inch diameter axles or # K71-384-00 for 2-3/8 inch diameter axles. This kit will let you move the leaf springs below the axle, lowering the trailer by the height of the axle and leaf spring stack. These are for use with double-eye springs only.

I have attached a short video demonstration on this kit that you can take a look at.

You may be able to use lowering blocks on your trailer to lower it enough, but you will want to make sure your existing tires are large enough to accommodate the new leaf spring/u-bolt position.
