Re: Can't Find Trailer Tires
Seems like 205/75-14 is the norm for trailer tires. Since they are both 205 mm wide, they should fit the stock wheels. You would want to check fender clearance as they are a little taller:
205/65-14: Diameter is 24.5" versus 26.1" for the 205/75-14. This means you need roughly 7/8" more room between the tire and fender width. The slightly larger diameter tire will turn about 7% slower, and since the sidewall is taller, you might get a little softer ride.
Wal-Mart has this size in most stores by the tire lube express area, already mounted on galvanized wheels for about $110. In a pinch you could buy one, install it and check for rubbing. If all is well either keep them or bring it back and get the ones you wnat installed on your rims.
