Hey guys, this is my first time on the Lawnsite. I'm looking for some advice about new tires for my 1997 Chevy X-cab Z71. Right now I have LT 265/75 R16 Cooper Tires. The front passenger tire is deteriating and Im looking into getting bigger/better tires. I would like to get some 33"s and something a little bit more wide and Im hope to get either BFGoodrich Muds or Allterrains. The tires I have now are way to skinny. But my problem is the width. I have standard Chevy rims that come with the z71/silverado package and i like them alot. I really dont want to have to shell out another 500 bucks for new rims. So i guess what im asking is how big of a tire can i get with out replacing my rims. They are 16r, but everything i see in the 33X12.50 and 35X12.50 are for 16.5r. If you have any knowlege or expertise in this area, please feel free to email me at firstname.lastname@example.org, Thank you.
