Tire size?

[Fish TR19]

My trailer has ST215/75R14 load range C tires on it. Well it's time for some new tires and I can't find any that size in stock at any of the local tire shops.
There were a lot of ST205/75R14 size in stock. Also load range C.
Would it be better to keep the 215 size or go with the 205 size? I was told the 205 would be a little smaller dia. and that would be the only thing that was different. I told them just to go on and order the ST215.
Was that the best thing to do or would the ST205 size be OK too.
Spare is still gonna be ST215. Replacing the other two cause I cut the sidewall on one of them at a boat ramp on Smith Mt. yesterday

The 205's dont carry the same load as the 215's... Good choice with the bigger tires.

Thanks for the reply. I didn't even think about the load not being the same.
