Mx 4700 tire pressure?

[Big Mike]

My Mx4700 4x4 has the following tires:
Front- 9•5-16 6ply rating
Rear- 14-9-26 6ply rating
My manual only list air pressure for 4ply tires. Which states 30# front and 20# rear.
Do 6ply require more pressure?
My rear tires are loaded, does that matter?

thanks

The loading DOES not matter ........ assuming that they are not 100% filled - should be about 75% filled - and you will know this if you rotate the fill valve at 12 o'clock and allow a little air to come out - if air only - you are in good shape, if fluid comes out - you are over full of liquid.

AS for the 6 vs 4 ply - the PSI should be about what you are doing - heavy load require more PSI - FEL needs a little more PSI - if grip is what you are after, a little less PSI in the rear.

I should have mentioned I do have a fel
