I used automotive tires on my 1st. 3 Seat SXS back in the early 70's.
No springs just tire pressure for suspension. Falcon ft wheels , Ford Tk.rear.
Used inner tubes, allowed lower pressure better ride & keep bead from breaking.
Ran this home brew until --( pre Forman )1986 Honda TRX 350 4x4 Came out -- kept that one 14 yrs.-- Until the 2000 Forman 450 & then 500
