The tires on my trailer say 78 R 14 on the sidewall.I can't see anything else. My question is can I put a set of ST 205/75 D 14 on as a set of replacements? Please help as I am going to pick these up as soon as I can find out if they will fit. Thanks to all who reply.Leo

You can't read the initial letter on either sidewall of either tire?

yes, but use 215's that will give you about 300 more lbs of weight cap.( n 4 tires, approx. 80 lbs per. ) what trailer and boat are we talking about. how many axles

I'm almost positive they will fit. F78 are bias ply and may be slightly taller. 205is your overall size, inner lip to outer lip. 75 is your height (close to your old 78). Don't forget your spare. If it is an old bias ply as well, you shouldn't use it with these radials.
