I am looking at changing to a 19.5 tire, I have a 2013 with stock ride height. I have searched for two days and can't find out if a 245/70R19.5 tire will fit without any mods, I could go with a 225/70...
I have an 08 Silverado 2500 and had 285/75-16's under it. The installer had to cut some of the liner at the firewall to get them to fit. Just had to watch at full lock as they would rub a bit. however, you are usually going slow at full lock , so should not make much of a hindrance. Get the dia,enter of your current tire and look at Rickson's website. They list dia. of the different size tires and you can make the decision for yourself if they will work for you
