The tires fit on the rims but would not "seat" so they could pump air into them. They felt it was the stiffness that was keeping it from sealing around the rim.
The tire dimensions were as stated on previous post " 285/35-19 are 11.2 " wide and 26.9 tall will work great".
Just wanted to let people know that the RunFlat in this size would not work (unless someone was able to put them on a stock rim, maybe under a different manufacturer).
