Higher Capacity Wheel and Tire Setup Recommendation for Toy Hauler Used in Sand

Updated 04/12/2019 | Published 04/11/2019

Question:

We regularly go to Pismo Beach with our Toyhauler. In order to successfully navigate the beach sand, I have to air down my truck and trailer to near flat. I run about 14psi in my truck and about 25 in the trailer. This gives me a nice wide footprint and allows me to get to my camp spot without getting stuck. Is this tire so stiff that it will not flatten out and give me the wide footprint that Im looking for? Im told this could be an issue with a tire of this type. Im currently running a G rated Westlake tire that came with my 5th wheel and they work very well in the sand when aired down. Thanks!

For what you are looking for the most ideal setup will be one that has more sidewall than the 17.5 inch wheel setup you referenced as the more sidewall you have the more the footprint can easily expand when aired down.

So going with a 16 inch wheel and tire like the part # A16RG8BMMFL would be a better option. You get the higher weight capacity of 4,400-lb maximum load at 110 psi and since the sidewall is larger (due to the wheel being smaller) you'd end up with more of a footprint. This also has the same 8 on 6-1/2 inch bolt pattern you are wanting too.
