Okay you got my interest. I know we all wish we had another inch or so more. What is the measurement that you have now? Unless I am missing something putting on the 85s you will loose only a half an inch. I know loosing anything is not good
I have been running the Carlisle Radial Trail RH st235/85R16 F for now going on over two years. Traveling over all type terrain done good with know none issues.
Of course I have a verified Raptor,ie no Fake labeling
. Would be interested in your measurement. Canesfan as soon as it gets as warm here as your Temps will go out and look at what you are referring to. Better get tires on your trip coming up
