Wondering what psi people are have luck with on 18.4x38s.
18ā wide rims Firestone Radial Double cut 8500lb pro farm 800-1000 hp tractor First season running. Been running 12psi. Wondering what some other people are running. Edited 1 time(s). Last edit at 08/26/2019 10:42AM by 8030acpuller. |

Agreed

I'd say you are close. You have to go with what is working for you. Not all setups will be the same. |

When I ran that size radial my tire cutter said stay between 24-26 because they are radials and they work best with more air. Mine always hooked hard |

for sure what works,double cuts are best at speed , -- which you have,amount of pressure is dependant on hardness of pulling surface,, -- hard track hard tire,soft - less air, however that is all relevant,what starting pressure do you have,some run as you see,-- much more,many a lb. per thousand of weight of tractor,I ran 13500 slow,250 hp,used 30 lbs in a road worn radial,-- worked awesome,beat many other higher powered tractors. Each tire has it's own sweet spot,how broke in the sidewalls are,age,hardness and so on,,have someone you trust watch sidewall while pulling,might want a little flex and squat in tire,or you can feel that when you put clutch in,tractor will rebound, -- which you can feel |

Iām going to try this next hook. When watching videos I can see the tires squatting a lot, losing hitch height.
Gonna throw some air in them and jump up a gear I think |
