    I have a 2013 chevy silverado z71 4x4 and i'm putting on a RC 2.5 suspension lift. I'm looking to put on BFG km2 or toyo open country m/t but i dont know what is the largest size i can put on my factory 18'' rims without any rubbing or cutting of plastic??
  2. On factory rims you can go with 33's

    Just courious what makes that kit considered a "suspension lift"? It's a level kit with rear blocks correct?

    Like ChromeSilver said, 33's on stockers would be your best bet. I stuffed a set of 295/70r17 Nitto's on a 2.25" level and liked it....just had to cut plastic

    No cutting on my rig with 33/12.50/18's! Look into my garage.......

    I just called it a suspension lift because that was what it was called on the site. I'm looking at the 285/70/r18 BFGs KM2.... Anyone know if they will be too big or what? They're 33.7s but I don't know if that is too much or not?

    I have a 13 silverado with a 2.5 rc lift and was wondering if I could run 285/70/r18 without having to shave any to little plastic

    Not sure about the 33.7 but on my 2010 33.5 fits with no trimming at all with just 2 1/2" level up front with 3" rear block but there's not much room left over up front. that extra .2" might mean some plastic trimming. I went with the Toyo's because I used to have the BFG AT KO's and they are similar in tread, but the Toyo's have a tread warranty where the BFG's have none.
