The Toyo AT2 Xtreme's are available in the following sizes:
16"- 305/70, 295/75 and 315/75. 17" - 35x12.50 and 285/75. 18" - 35x12.50, 325/60, 285/65 and 28575. 20" - 35x12.50, 285/55 and 305/55. 22" - 325/50. All the Xtremes are E load range and have a 50k mile mileage warranty.
On the 275/70R17, really the only difference is the OWL has white letters on one side and the BLK has black letters on both sides. In some sizes you'll also see a P and LT version. The P is the standard load capacity (which works on most F-150's) and the LT is the heavy load capacity (F-250 and up). Any other questions feel free to call me at 888-421-8473. Just mention the forum so I know who all is a member. Thanks guys
