Your "new" 5er has a GVWR of 15,000 pounds. When loaded for a long trip, it will have around 3,100 pounds on each trailer tire. The biggest Michelin XPS Rib is LT235/85R16E or LT245/75R16E, with 3,042 pounds max load @ 80 PSI. Great tire, but not enough weight capacity for your heavy 5er.
Michelin makes cheap tires, good tires, really good tires, and great tires. The XPS Rib is one of the great tires - and the cost should hint that it's not an ordinary tire. Don't expect other Michelin tires to be as good as the XPS. But since Michelin doesn't make an XPS for your trailer, you are forced to find a different tire.
3,100 pounds weight on each tire plus 25% safety factor = 3,875. So for your trailer I'd want tires that have a weight capacity of way over 3,100 pounds, and preferably close to 3,875 pounds or more. If your rims are 16" diameter, that probably means you'll have to look at tires with G or H load range. Check the size of tires that are on there now, and look for tires at least Plus 1 size larger, and load range G or H.
For example, Maxxis UR-275 in size 8.25R16 has 3,970 weight capacity with 14-ply rating (= H load range). I've had excellent service from Maxxis tires on my trailers. I can get them at Discount Tire, but they usually don't have them in stock so I have to order them.
