I would not run that tire on my LT as it is not load rated (73V vs. 79V) for it and from the BS web site it can be run on a tube type rim.
"160/70B17 M/C 73V TL 4.50 3.75～5.00 656 158"
Ok so a 79 V tyre is rated at 437 kg at 210 km/h
A 73 V tyre is rated at 365 kg at 190 km/h
The LT curb weight is 387 kg and has a max weight with two up and luggage at 600 kg. So two up with luggage you have already exceeded the theoretical rating of the 79 V
My understanding of the V rating is that relates to the top speed , as in that is the max weight you should carry if travelling at the top speed.
Now bearing in mind that the weight of the motorcycle increases with centrifugal force as we go through a corner I doubt that any of us is approaching any where near the top speed rating in a corner.
I long ago removed my top box thereby saving 15 kg so I have reduced my curb weight to 372 kg. I weigh 87 kg, mostly ride solo, and the heaviest thing I have carried any distance is a couple of pair of pants, a couple of shirts, and toiletries and I did all that on the Michelins that were 69 V rated tyres. ( I knew no better at the time, ignorance is bliss )
When I bought the LT I did so because I wanted a big comfortable bike that I could enjoy riding sedately, I have exited my 5th decade and my days of sports bike riding are well behind me.
I really don't think I'm in any danger of sudden tyre failure.
