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 # AC15R45WSQ 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.

I just bought a twin axle trailer, it's heavy duty, it was used to carry a small excavater at one time. I am going to use it to carry my golf cart. My "Q" is, can l register this trailer as in a "lite class" catagory? 96186

I'm pretty sure the weight class has to do with the GVWR of the trailer and not what you plan on using the trailer for. I'd try checking your State laws and maybe your local DMV or highway patrol for guidance on this. 71036

@JonG in PA you can register the max the trailer is rated for or below. So weigh your trailer with the max load you will carry and the total is what you need to register. We had a DMV officer explain it. 73658

Would a st205/75r15 omni trail tire work for a 26 foot tandem axle rv 3500 gvw front and rear. It is class D 8 ply 107 tire load index. thank you 75746

Reply from Chris R.

Yes, this tire size and load rating would provide more than enough capacity for a 3,500 pound trailer. 61885
