yep the size is definitely a problem.. not much in that size... i cant even order the dueler HT in a 245/60/18 anymore, only the dueler HL. its easy to up the size of your tires though to a more common size like 255/55/18 (no difference in overall height) 265/60/18 (small difference in height) or a 285/60/18 (pretty big difference, but little to no trimming required
