Thanks gents!  Your advice seems totally solid, maybe because that's what I was thinking too!

And I calculated the slope to the side of the shorter tire at about 1.5%, which is less than the typical crown on a paved road.

I think I'll carry my smaller spare until I find a good deal on a larger rim. And I hope I don't have to test my rationalizing.

I think for emergency use, you would probably be OK. If there was a differential involved, it would be a most definite no-no. Be aware that the different sizes will be rotating at significantly different RPMs, and that there would be a slight list to starboard (or port) with the trailer. Like Mike says, it would not be for an actual trip.]]> Tue, 25 Sep 2018 08:46:50 +0000 http://www.rpod-owners.com/forum_posts.asp?TID=12244&PID=115624#115624 Different-sized tires : Small diameter spares are the... http://www.rpod-owners.com/forum_posts.asp?TID=12244&PID=115620#115620 Author: mcarter

Small diameter spares are the norm in the auto industry, you could travel a short distance with 2 different diameter tires on a trailer. I wouldn't recommend it for the full trip.]]> Tue, 25 Sep 2018 08:26:10 +0000 http://www.rpod-owners.com/forum_posts.asp?TID=12244&PID=115620#115620 Different-sized tires : Just wondering whether it would... http://www.rpod-owners.com/forum_posts.asp?TID=12244&PID=115614#115614 Author: poston

Just wondering whether it would be a problem using a smaller/bigger diameter tire as a spare?

I bought some 15" tires from Kris B, but only bought two rims.  Didn't think about the spare.  I could get a cheapo 15" rim for the spare.

But what if I used one of my 14's as a spare to drive on in an emergency until I could get the flat 15" repaired?  The 15's are about 2.8" taller.

All my vehicles are 4WD or AWD, so I can't do that on my cars, but what about on the trailer where both hubs are independent?
