Actually brands are super helpful with tyres. There is a clear pecking order that has been established through millions of kilometres driven by millions of people. An opinion on a tyre reflecting size and conforming to a particular vehicle can possibly be given by an owner of such a vehicle with the particular tyres on. This you will be challenged to find, especially someone who has gone through several different brands.
BF Goodrich is a good tyre from the middle class of tyres - though not a Michelin, the tyre has generated a following in the off-road circles in particular. I see that you are looking now at AT tyres... Here you really need to consider the difference between passenger and all terrain tyres. From what you have written, I do not see why you would go for AT. Passenger tyres provide better traction on asphalt, better fuel economy and the ride is smoother with less noise. AT is a compromise for road drivers that like to test their vehicle off the beaten path now and then, but do not want to switch tyres. I would recommend that you find someone around you with AT tyres and drive their vehicle, but do not drive for 2-3km - drive for 2-3 hours if possible.
I am unable to comment on "ply" as I suspect tyres are marked in a different way in Europe - what does ply stand for? It is indeed frustrating when "professionals" cannot explain what their product is and why you should buy it.
Here we have, apart from the size, speed rating and load rating. In the registration of the car all of this information is included - if the tyres on the vehicle do not comply on any parameter, insurance is invalidated in case of an accident. Not a fun situation. My car's max speed is 170km/h, but I am required to drive with tyres of up to 210km/h - do not like it as I usually do not do over 140km/h, but have no choice.
With regard to tyre width - wider tyres are generally for the summer. I drive in 245s in summer, which I replaced a month ago with winter 225s. Again, my car has two approved of tyre sizes - 245/70/16 104H (104 is load index, H is speed rating) and 225/75/16 104H - not all do - most likely have a single approved size. I am illegal with anything else - check your truck's documents/registration papers or information on the car itself. Here we have metal plaques that specify this along with pressure. Do not remember how it was on the cars I had in the US... Here it looks like this:
I currently drive in Michelin Alpin LA2 (very happy).
In the summer had Kumhos (inherited, never would touch them otherwise).
Before have driven in Cooper Discoverer M+S (not bad at all, but M+S are again a compromise - neither summer, nor winter tyres, but still legal for both seasons). Towed my trailer like a charm.
Continental Contiwintercontact (very happy)
Also other brands before, but do not remember their names anymore.
All of these are passenger tyres - toyed with the idea of AT, but decided against it.
How many miles did you get on your Michelins and how much thread do you have left?
