Can't find my tire size

[byoc21]

I bought a trailer real cheap and it needs a new tire. The good tire says 6.5 x 13 6pr but I cant find this size anywhere. It has 5 lugs. Is there another size that works?

175/80 13

or

165/80 13

Kinda depends on your rim size. These will fit 4.5" wide rims.

Re: Can't find my tire size

Everything now is pretty much metric sizing, so the dims Bruce gives are correct. I'd go ahead and get a PAIR of something that matched however given the probable age of your "good" tire. You can buy complete tire/wheel assy's for about the same as the tire alone. The one thing that stands out is the 6 ply rating of your good tire so make sure you get new ones with at least that on the sidewall and of course, be marked ST (Special Trailer) before the size, ie. ST175/80-13.
