if the tires are unloaded and it's not a huge loader.. it's probably ok.
I can tell you I've for sure done it. but can also tell you that I got a bigger truck and trailer so that I don't have to do it anymore either.
i have an 850 with superior utility laoder on it and loaded 13.6-28 tires and a counterweight that probably weighs more than that 3 cyl and laoder.. and I've moved it on the trailer.. and only did so because i had a 1 ton pulling it... and knowing it was abusing the trailer too.. and it was a short 8m trip.. no way I'd do it on 100m
