Discount just put some new Coopers STT's on my truck..We had balance issues with those damn Hankooks! One was out of round and made the whole truck bounce at around 50 mph.The bad one was replaced and the truck was still bouncing,so after re balancing 5 times they agreed to replace them...
I prefer the stiffer sidewall of an E rated tire when pulling.I dont like the "swaying" feeling of softer shouldered tires.You should be fine for plowing though.If you want a taller tire,285's will fit on stock rims just fine by the way.
My newer bikes dont vibrate at all.At least not compared to my 66,and I balanced that motor to the limit to get rid of most of it!!!I'll deal with loctite over lost nuts and bolts any day,but the red one really sucks to get off sometimes.
I bought a set of Two year free replacement batteries from Checker.They are made by Exide . Autolite Platinum Battery: 770 Cca.Seemed like a decent deal.I payed $68.00 a piece.They are all made by a handful of company's anyways.
