depnds on what kind of tire you have, tubeless or tubed, chains or no chains

my rear tires i have chains.. so i need them pretty well as hard as possiible.. but without them.. im sure you can make them quite soft before worrying about twisting the rim and tire...

[MOWchanic]

I have a tubeless tire.... no chains...

[speeddemon0308]

well.. make them semi hard.. and go for a ride.. bring a pressure gague with you and every minute or so let out a pound or so until you get it to were you like it ( and some paper so you can write down were you liked it best..)

[MOWchanic]

Will do.... Hopefully will get to have a ride this weekend, if not the next...

I know before i modded my Case, i did a little rut running with it. With standard turf tires, the sidewall was still enough for me to leave them flat and they gripped well. Biggest thign you gotta watch for there is the rim spinning in the tire.

I would run maybe 5psi

      Hey Guys,   I  need more advice  about my ATV,

      Phil, - - - -  I saw your post about running a mower on five pounds  [psi] of air in the tires.    That really got my interest about my ATV.     The booklet that came with the ATV is very poorly written.   On one page it states the tire pressure at  :     kPa 100.    which on my gauge is about 15 psi.    With this air pressure - - -  I could  "feel" almost every stone in the trail.  A  very hard ride.    I reduced the pressure to 7 psi.  This ride is much better but still appears to be somewhat "hard".   I'm concerned about the rim or tire damage or even  the tires slipping on the rims if I reduce the pressure further.   Your thoughts on this?

Drop it down to around 5 PSI and keep an eye on the clearance between the rim and the ground. Overall it should be good. If you do a lot of hard core riding such as sharp turns at high speed (which i dont see you doing normam) then all should be fine.

I know when i used to do garden tractor pulls, we ran anywhere from 3 to 15psi , depending on the track conditions.

     Thanks Phil,  You're right about the sharp turns  and excess speed.   I left " SPEED" about 45 years ago,   I'm 74 plus at this time.        [ And  going strong again]    I'll give 5 psi a try.

Depending on the wheels and tires you might be able to safely air down to 3PSI. The only problem with such low PSI is the possibiltiy of rim damage or breaking the bead. As long as you're easy I don't see you damaging the rim, but breaking the bead is never fun. Out of all the tires I've ever mounted and dismounted, I absolutely hate ATV & lawnmower tires. It's a pain to mount them, it's a pain to dismount them and it's even more of a pain to seat the bead.

      Hey Chris,   Always  good "hearing" from you, 

            That's really something to think about,  especially if you're out on the trail.    Let me say something that most of you already know about.   One time a friend of mine had a tough tire that went flat and became  loose from the rim.   He and several other guys tried everything to get  "THAT DUMB THING"  back on the rim.  Not much of a problem if you've got a lot of high pressure   air.   It looked like a 17 mile trip just to get that tire back on the rim.      Then along came a "caveman" and put a rope around the outside [tread] of the tire - - - - tied a knot - - -  put a stick  under the rope and started twisting the rope.   Well that tire along with some soapy water went right on that rim .   Air from a hand pump  put enough air in to keep it there.   

            My friend said something about watching these cavemen with their sticks and stones.  

            Have a good one,            caveman
