Today was as wet as they come here (Norway), plus it gets dark at about 1530 right now. So After work I have most been organising wheels and tires! Pretty fascinating amount of confusion out there if you want to convert to single rear wheels.
I quickly fell in line thou and abandoned the 20" realm and ordered some 11.75-22.5 IS 110mm from a reputable German supplier, although these will not be available until January 2021 (apparently there is a trucklife boom in the EU at least).
Took me a bit of time to understand the offset issue since these wheels fit flip mounted on the front/back, so the greater the offset the more inverse that will be on the front axle (i was told the front axle track is always wider).
Now, tires, i have opted to have them mounted and shipped along with the wheels, works out quite a bit cheaper than buying them in Norway even with the 25% VAT and import charges. I went for the Nokian R-Truck Steer on both axles (I was assured that was alright). I have a long standing trusting relationship with Nokian tires and really like the tread profile! I suppose looks matter, who knew
?
So, all being well I should have these by mid January sometime and will probably mount them early spring for our trip down to Germania!
