6.70-15 is an older tire size that can be replaced by 205/75-15 tires, which we do offer.

I recommend going with the Westlake ST205/75R15 Radial Trailer Tire - Load Range D, # LHWL300. This is a great radial tire with a maximum load of 2,150 lbs. The tire includes a 5-year warranty and 2-year complimentary roadside assistance.

If you can get away with something less heavy-duty than a load range D tire, I recommend the load range C Provider ST205/75R15 Radial Trailer Tire, # TTWTRTM2057515C. This tire has a maximum load of 1,820 lbs and includes a 2-year warranty.

These two tires have an overall diameter of 27.1 inches and a width of about 8 inches. Your current 6.70-15 tires have an overall diameter of approximately 27.4 inches and a width of approximately 6.7 inches, so the new tires would be very similar in diameter and just a bit wider.

I've attached several review videos of the tires if you'd like to check them out.

Answer 4

From what I could find out about the 1954 Spartan Trailer line, it does look like they used the 6 on 5 1/2 bolt pattern for their 15 inch wheels. That being said, this should be verified before finalizing anything. 6 Bolts are pretty easy to verify…

A blowout can be caused by any number of things, from the trailer being overloaded to the tire being underinflated (or underrated) to just a poor quality tire. In general, the higher the load range and capacity the higher the ply rating will be, so…

Answer 9

Trailer tires and wheels do not typically come balanced from the factory like what you see with standard passenger vehicle tires. This isn't usually needed for trailer tires and most car shops don't have the needed setup to properly balance…

It's not ideal to have a spare that's a different size than the rest of the trailer tires. If at all possible your best option is going to be to replace that tire with the correct size. But if you are stranded on the side of the road and you…
