I hope to get some opionions on tire Brands. I have a 36ft motorhome and I need to put 4 new tires on the back. The fronts are new and they are Falkens. The size is 245 70r 19.5. I can pay up to 350 a tire. I do NOT want any Goodyears of Firestones. If you feel free to give me ideas of what you believe are good tires I would really appreciate it.
