I just had the Readylift leveling kit installed on my 2010 Sierra, so now it is ready for the wheels/tires. The only information that I can find is on the Readylift site. It says that I can fit 33s now. So, I was thinking some 20X9 Ballistic Off Road Jester wheels with 295/55-20 Nitto Trail Grapplers. The Nitto site says that the inflated overall diameter is 32.91 for the 295/55's, however the guy where I'm planning the purchase says that I should go with a 285/55-20. But they don't make Trail Grapplers that size. I can't find a guide that would answer my question. Since I'm buying online, I need to know before I order or I'm going to have to pay to ship them back across the country. Can they fit? Also, the same place will be mounting and balancing and they say for 200 bucks they can put stems on that work with my TPMS. He said I'll I'd have to do is throw the wheels on there and everything will work. Does this sound right?
