The LT on your tires stands for "Light Truck" and while there aren't any specific replacements for 5.75 x 15 tires, what that size means is you have 15 inch diameter wheels and tires that are 5.75 inches wide. The closest we offer to that size is a 205/75-15, which is for 15 inch diameter wheels and are 8 inches wide. You may need new wheels as well because these tires are designed to fit 15" x 5", 15" x 5-1/2", 15" x 6", and 15" x 6-1/2" wheels.

The option we have with the highest load range is the Karrier ST205/75R15 Radial Trailer Tire - Load Range D # AM10245 which are 8" wide and 27.3" total in diameter, and fit one of the aforementioned wheel sizes. Keep in mind with trailer tires, the general rule of thumb is you want at least 3" of clearance from the top of the tire to your fender and at least 1" of clearance between the inside of the tire and your trailer's frame rail.

I have added links to a number of help articles on trailer tires which I recommend checking out.

We do have 15 inch galvanized wheels: - Steel Spoke Trailer Wheel - 15" x 6" Rim - 5 on 4-1/2" - Galvanized Finish # AM20524 - Steel Spoke Trailer Wheel - 15" x 6" Rim - 6 on 5-1/2" - Galvanized Finish # AM20534 The 5 on 4-1/2" and 6 on 5-1/2" refers to your bolt pattern, which you need to know in order to get the right wheel. If you aren't sure of what your bolt pattern is I've added a link to a help article on how to measure bolt pattern as well as a handy template for bolt patterns.

The closest thing we have to an 8.75 x 16 tire is a ST235/80R16 trailer tire, which is 9.3 inches wide compared to the 8.75 inch tires you have now. For this size tire I recommend the Westlake ST235/80R16 Radial Trailer Tire - Load Range E # LHWL401. I really like the Westlake tire because of its deep 10/32" tread depth and the fact that it has a 5-year warranty, which is quite a bit longer than most. These tires also have free roadside assistance for two years just in case you should ever get a flat, which is a huge benefit for travelers. These will fit 16 inch wheels with a 6 bolt pattern such as the Steel Spoke Trailer Wheel - 16" x 6" Rim - 6 on 5-1/2 - Galvanized Finish # AM20747. I have added links to video reviews for you to check out as wel.
