My question is what is the danger of having 20 psi in my 2 center carlsisle at101 tires and 15 psi in my 2 rear carlisle at101 tires?All 4 tires are new and I will be buying 2 more for the front axle soon.I installed an adjustable weight suspension seat and it also slides forward and back and man my scrambler rides like a 1972 sedan deville!-The new carlisle at101's are serious tires that rip the lawn when I turn so I figured the higher air pressure helps the scrambler turn easier and the contact patch of the tire is smaller.Please let me know if I am wrong-I figured that with the cool suspension seat absorbing all the shock and saving my spine then I could air up my tires and not worry-however if less air means better steering then I will go back down to 5 psi-I do not have bead lock rims.Thanks in advance Flippy

You are correct that it will help you to turn more easily, but by having such a high pressure, you will lose traction and that will hurt you on the trail. Even with the suspension seat, you still need all the help you can get absorbing shock for both you and the six wheeler. Finally, I believe those are low pressure tires. You may be exceeding the max rated pressure?
Really, if the only reason for running such a high pressure is to save your lawn, don't ride on the lawn or don't skid steer. Then, run the proper pressure and enjoy it on the trails.

It does sound high. Whipper & I are springered & we run 6 - 8 psi depending on what it takes to get all tires an equal circumference. If you want the center tires larger, remember to not go strictly by psi to get them equal, because some tires will be sometimes a 1/4 to a 1/2 inch different in size with the same psi in them.

Thanks for the comments-the sidewall states 25 psi max pressure but the main thing on the sidewall that I like is Made in the usa!Comment

20 psi?! Wowzers.... Take it down to 3 to 5psi. The low air pressure isn't just there to save your spine; it's there to take some of the load off of the drivetrain components. The (1"?) axles and bearings will all benefit from the lower psi. If you start running into issues with the tires coming off the bead (unlikely on the lawn), then you can boost up the air pressure a tiny bit.....sigpicComment

25psi sounds like the mounting pressure to seat the tires.Comment

Yea it says it's the mounting pressure but with me being a rookie on this whole ATV tire thing I was not sure.When I was 16 I worked at a sunoco with a auto repair hoist. A car wash and tire sales and repairs.If a tire ever came back after a repair it had to be repaired for free.The owner of the place instructed us rookies that if a tire ever came back with a slow leak and you could not find the bubbles. In the tank then break the beads coat the tires beads with tranny fluid then air the tire up to 80psi.His method worked every time but unfortunatley it has had some effects on my 44 year old brains use of logic..Comment

My opinion:
For the machine's sake you want all of your tires to be exactly the same diameter.
For the tire's sake you want enough pressure so that the tire carries the vehicle and the sidewall doesn't ever get pinched by the wheel rim.
For your sake and traction's sake you want the lowest pressure that still keeps the bead.
All of this is dependent on the conditions you run in. In my experience I can get away with lower pressures on hard ground than deep sand.
I suspect heavy mud is more like sand and water is more like hard ground.
If you never turn then go with low pressure and then look for a more fun place to ride.
If you are only ever on hard ground and you don't mind the increased wear/decreased power, I can understand the logic of going a little larger diameter in the center for increased turn performance.Comment
