I've had 35's, 38's , 33's on different 4x4s over the years ... I currently run 33s on my 80 and it's fine , goes wherever I point it and have a stock height ome kit plus 1 inch puck in the front for the anti stink bug. Arb front with 10k warn, WK sliders, labs dual swing rear, 4:56's with harrop and it works great ! At 43 yrs of wheeling and 59 yrs on earth , 33s are big enough and go anywhere a 35 will go ! I don't need 35s much less 37s for it seems a lot of folks vanity of compensations of how things look ... ha
