What make, model, and size format tires? I'm in the process of getting
my M11006 on the correct size, already landed one pair of IRONMAN® RB-12's in 215/75R15 100S for the steer axle at Tred Shed® Tire Pros (50 Bliss Avenue, Pittsburg, CA 94565-4938 USA). (The drive axle's shod with undersize tires, spec. Venezia® Classic 787 in 205/70R15 89S, which are already on the replacement schedule for January 2020.) Still have to find me a ø15"x6.5" stamped or spun steel for a full-sized spare as well; the T145/90D16 won't even level the truck.
