Hi everyone, I'm going to install the 2" TerraFirma lift on my 04 Discovery II HSE. I plan to keep the OEM 18" wheels and would like to install a larger all-terrain tire. What is the largest tire size I can install that won't rub. I don't want to modify anything on my rig to avoid rubbing. I'm thinking 30.5 but would love to hear from those of you with experience. Thanks! P.S. Brownie points for tire make/model recommendations for good AT tire.
