When considering a different tire size for your trailer you will want to make sure you have the clearance you need for wider or taller tires. Since you said you have 205/75-15 tires, going to a larger tire like a 225/75-15 will be a bigger diameter of about an inch. When checking for clearance it is always best to have a minimum of 3-inches clearance from the top of the tire to the fender because of tire deflection.
I recommend using radial tires on your trailer. Radial tires flex more than a bias-ply tire and will run cooler, which means they will last longer.
I could not find out what size axle you have on your trailer but you can measure the diameter of your axle to get a pretty good indication what the axle capacity is for the trailer. Here is a list of axle capacities based on the axle diameter:
- 1,000-lb - 2,000-lb Axles: 1-1/2 inch - 1-3/4 inch diameter
- 3,500-lb Axles: 2-3/8 inch diameter
- 6,000-lb - 7,200-lb Axles: 3 inch diameter
- 8,000-lb Axles: 3-1/2 inch diameter
- 9,000-lb Axles: 4 inch diameter
- 10,000-lb Or more axles: 5 inch diameter.
If your trailer is rated for 7,000-lbs I would guess the axles are rated for 3,500-lbs each.
When choosing a wheel you will need to know what the wheel bolt pattern is on your hub. I have attached a helpful article that explains how you can determine the wheel bolt pattern on your trailer.
You may be interested in a tire/wheel combo. I have attached a link to the combos we offer, but you will need to know the bolt pattern to make sure it will fit your trailer. I also attached a link to 15-inch wheels and another link to the 15-inch tires we offer you can check out.
