The wife and I got an airstream last month and I've been beefing up the LR4 where possible. Since I can't get a load E tire for the OEM 19'' or 20'' wheels, I went ahead and pulled the trigger on the new DakarZero 18"x8.5" wheels from EVO Corse. Most people buying these wheels get them for off-road, but my main purpose is simply for a better highway tire while pulling the trailer. Does anyone here happen to have a resource/past experience with how the different 18" tire sizes affect the LR4's gearing? 265/65/18 seems to be about standard, but I'm wondering if I mess with sidewall height or tire width how that would affect RPM's at 65MPH
