You can potentially switch from ST205/75R14 tires and wheels to ST205/75R15 tires and wheels but you first need to make sure that there is enough clearance all around the existing tires for the larger size.

The 14s that you have now are abut 26.3 inches tall and about 8.1 inches wide.

The 205/75-15s will be about 27.1 inches tall and about 8.1 inches wide.

The width is the same but the 15s will be about 0.8 inches taller which means that there needs to be clearance above the existing tread greater than half the difference; so 0.4 inches. If there is enough clearance you can switch sizes.

I recommend # MX97FR which comes with a silver acrylic enameled steel wheel and 5 on 4-1/2 bolt pattern. It is rated for 2,150 pounds at 65 psi and 81 miles per hour.
