Replacing 2 tires, where should the new ones go?

2nd that! And bring one with you.

Does not matter as long as they are on the same axle.

I own 3 duel axle trailers & have never rotated tires see no need. they wear the same. Always age out long before the tread wears out.

Which brings me to how old are the other two "good" tires. If they are 5-7 years old replace all of them.........

I'm not sure if the steel spare wheel is rated for 110 PSI.

keep one of the newer ones as your new spare.

It is a trailer, so the tire position does not matter at all.

Ditto... front or rear, makes no difference, but I'd say they should both go on the same axle (in other words, put both on the front or both on the rear)

When replacing tires on a trailer I do them all at the same time unless one picks up a big screw or other object... in which case I replace the one.
My experience has been that when one goes the rest are on borrowed time and it is easier and safer just to bite the bullet and get them all replaced...

On tandem axle trailers, I always would put the new tires on the front axle. Sometimes the front tire runs over a nail or screw safely and throws it up into position for the rear tire to get punctured; I have had this happen too many times to count. And I'd rather puncture an old tire instead of a new one... ;)

Now all my trailers are single axle ones, and I have way less nail and screw problems.

Thanks for all of the replies. I'm just going to get 4 new ones.

While not a tire expert the tires you are not replacing should not be moved to another side of the TT. That being said I'd put the new tires where there is more axle weight.
