For those of you that live in the Pacific Northwest that have a Les Schwab tire store nearby they have a GEOSTAR G574 G rated All Steel Highway Tread in ST235/85-16 Radial, 3750# capacity @ 110# pressure (of course made in China). I purchased 4 a year ago last August for $259.72 ea (free rotation, rebalance, pressure check etc). Probably have over 4,000 miles on them, the thing that amazes me is that when I take the RV in for a pressure check they almost never require any air. Looking forward to going to AZ/NV/SoCa for the winter in a month or so and I don’t have any tire worries.
I have been told that Geostar tires are sold by some other tire dealers throughout the US. Check out their web site.
