More wheel and tire options

[DarkVader]

The rims on my chassis (Spartan) are 22.5x6.75 six bolt rims. The tires are 235 80 R 22.5.

I've found that these rims are a bit harder to find and was wondering what my different options are.

What's the best way to determine if I can I go with a wider 22.5 rim, without buying one, putting it on, and turning the wheels?

Do bolt pattern adaptors/converters/spacers exist for large vehicles like ours?

I've never seen a 22.5" rim with only 6 lug studs, all I've seen have 10 lug studs. New ones are available though: https://buytruckwheels.com/collectio...s-20-tube-type
It seems the low-boy aluminum wheels are the ones hard to find:https://www.amazon.com/6X222-25-Alum.../dp/B01K0H00OS If you decide to look into these further I suggest semi-trailer junk yards.

Hopefully the Alcoa website will have more information: https://www.alcoawheels.com/alcoawhe...rica/en/rv.asp

I wanted to change to a larger front tire. Entegra didn't know and had me call Spartan who knew right away that I couldn't. Call Spartan.
