I`ve had the same thing happen to me with Goodyear Wrangler Silent Armors in a 265/75R16 , Americas tire wouldnt road force balance them at first , after going around with them , they finally did and 3 tires were bad ,wouldnt road force, had to be replaced
I`m looking to get visions W/ 245/70r19.5`s , dont know what tires yet , the visions at fourwheelonline.com are 800.00 for 4, W/ free shipping.
Theres no way I`d want to go thru what your going thru , I already decided to get tires local so I have the face to face if things go bad.
Your story would rule out wheelrack as a place to buy
I saw wheelracks adds 6 monthes ago , you can`t beat their prices for packages ,1500.00 for 4 wheels and 225/70r19.5`s but I thought about the -what if- factor if there where problems, at best you probably would have to pay return shipping
I`d like to hear how shaving them round goes , and how you end up feeling about the dynatracks when you get them round
Hope it works out for you
