Title: Alternatives to the 9R22.5 tire
Post by: Paul GA on May 07, 2023, 07:17:45 pm
Need to replace all six tires.  The chassis plate, and the tires on the rig are 9R22.5 with 6.75 width rims. Talking to tire shops it seems that size is not usually a stock item (thinking about on the road issues).
My research so far seems to be to go with a 245/75R22.5

9R22.5 - 9"W.  38.4"Diameter
245/75R22.5 - 9.5W.  37" Diameter

I like the 265/75R22.5 specs except it specifies a 7.5 rim
265/75R22.5 -  10"W.  38.4 Diameter

I'd like to hear what others have done in this situation

Thanks

245/75r22.5. It works perfectly and easily sourced.

Check your tach and speed with your phone . These speedos can read way fast and will read faster with the smaller tire.
  The 9R is  easy from Simple tire and works fine IMHO.  The 245 /75 is not that easy to find and seems to cost more.  Both will work .  You may have the 7.5 in rims . I do .   

 9R = 38.4 OD
245/75/ =36.97 OD
