I don't usually waltz in the LR4 forum here, simply because i own LR3, but in this case the same basic principles apply as we all (mostly) ride on the 19 inch wheels.
I am , as Paullr3 , also a strong advocate of Nokian tires.No affiliation whatsoever with a brand, in fact I was probably the first owner of them on lr3 forum back when I bought them.The Nokian WRG2 suv could be the last tire that you ever own GOLOAF.If you looking for something that will give you confidence all year around in rain, snow and slush, especially slush and is also very quiet, this is the tire you want , no jokes here.I had this tire for 60.000 miles thru a few winters, countless miles of gravel roads in Maine, summer and winter.For guys like me, as I am from NJ, or Boston area or any place that conditions change very quickly from rain to slush to snow and maybe rain again, this is the tire that will not let you down.It wears great, after 60.000 mies in various conditions and seasons i still have 4 MM of thread left.
It is not great in mud and picks up a fair amount of little pebbles , but that is nothing that you cannot loose on the speedy highway, right?
I actually had them on 18 inch rim in 265 60 18, load 114 XL and UTQG was 500 A A. Now 255 55 19 is 111 I believe , so you will not compromise a legal load and avoid future problems with insurance companies in case of an accident.
I deliberately said HAD them, as I retired them last week for another Nokian tire ROTIIVA AT in 265 60 18..Both tires are below 31 "(30.5 " exactly).I wanted a AT tire for a specific reason as I go off road quite often , also wanted all terrain tire with Snowflake symbol, that will get me thru winters safely.
I will probably stay with this brand til I am dead, simply because there is nothing remotely comparable to WRG2s on american market as far as all WEATHER tire, not confusing it with all season tires, which are by far mediocre if not poor in most conditions.
I should also note , that I had GY Wranglers before (terrible tire )and GY Wranglers Silent Armors on LR3 and they turned out to be unsafe , if not dangerous to drive around 30.000 miles.
The choice is yours , obviously, but you would not be here , if you would not looking for some sort friendly advice, right?You trusted an European car, why not give a try a European company, that won numerous awards on OLD Continent .Good luck.
