i have a 2005 silverado z71 1500 non hd truck , extended cab. current tires are 265/70/17 , i was wondering if the goodyear wrangler mtr's in the size of 285/70/17 will fit without rubbing, cranking the bars,without keys,without trimming anything. thanks guys

Should work fine. You may see a little rubbing at full lock off camber, but I dont think you will. I have some buds that run 305/70/16 in th stock rims, but most stick to the 285/75 on factory or aftermarket rims. The 285/70-17 should be the same as the 285/75-16
