Helpful Expert Reply:

For a tandem axle trailer rated for 7000 lbs, you can use either a Load Range C or D tire. Each axle will be rated for 3500 lbs so you need a tire that will carry 1/2 that capacity. That would make your minimum load range before limiting your system or 1750 lbs. The Contender ST205/75R15 Radial Trailer Tire w/ 15" White Spoke Wheel - 5 on 4-1/2 - Load Range C # AC15R45WS are rated for 1820 lbs at 50 psi and have a speed rating of up to 81 mph. This is a great tire, so the only reason for an upgrade to load range D is a higher ply rating on the sidewall of your tire.

If you want that, I recommend the Provider ST205/75R15 Radial Trailer Tire with 15" Silver Mod Wheel # A15R645SMDV with a 2150 lb capacity at 65 psi and the same speed rating of up to 81 mph.

For just the tires, the parts are # TR20515D and # C20515C.
