Re: tire sizes for rear of 1998 U320. Reply #25 – July 19, 2024, 02:48:52 pm I found that the 295 LRH at 70# steered a little squishier than the 9 R. At 90#. A valid reason to change tire size on the 4 spd bus might be to change overall gear. The 9R is around 100rpm faster at the same 63mph . I may go back to the larger drive tires next switch over .
