Rear Wheel Width

Recommended Posts

Hi All,


What is the standard width of the rear wheels on most 300 and 400 tractors?  How wide are the rear wheels on a GT1800?  What other machines use wheels the same width as the GT1800?  How much would traction and stability improve with wider rear wheels?  Thanks.

  I believe the standard width is 7” or 7.5”. The factory rear rims on the GT-1800 (and many 520’s) were 8.5” to accept the 10.5 wide tires. 

  Stability should be better with a wide tire/rim setup but traction actually gets worse as the rubber gets wider.
