would ag tires be a good tire for a trail truck? i found a 38x13-16" tire that would fit the bill, just put a set of 35" ats on when im not wheeling and thse ag tires when i am. are they worth it or should i not even bother with them? here is a pic of them

and here is the site where i found themtire site (http://www.tirexusa.com/simex/agri_tractor.html#SA507)

Seen it done, they don't flex the sidewall for crap - you need a heavy vehicle to make them work well for anything besides deep goo.

seeing as your from tennesee i say yes why not, they will prolly work good for you down there, if yah were out west id say no.

Yes, a club member has run them, but I personally would not suggest it. I think he rarely runs them except for when he knows certain trails he will be on where they work well.

well they'd be strong as hell im sure. Not street friendly but if you have a tow rig thats no biggee... Go for it! I dont think they would do all that good in the rocks but mud and wet, loose terrain they'd probably kick ass.

BTW: How much did you find the 38's for?

AG tires work good for mudders, but way too stiff for trail use. The firestone ag tires that are used for the front of 4wd tractors come in Jeep type sizes - couple guys around here use them for hunting jeeps, good for slews, but not for rocks and stumps.

what would it take to make the side wall flex?? o psi and a 800lb rig??

they would suck on the street, but who the hell cares they look sweet. run 5 psi and they would be sweet. if i had a trailer queen i would run them. super strong sidwalls i would bet. and they would grip like crazy! probably wouldn't need a spare!:nuke:

Like any other tires it has its strengths and weakneses.. you need to look at what you want from a tire and what kind of wheeling you do to see if this tire fits your needs.

More like 0 psi and a 12,000lb rig.

If you run anywhere that there are stumps, stobs, or stickers, you will have flats. Believe me, with that big void the lugs pull small stumps in and pssssssssssss. At least that is what happens on my tractors running over the same ground that I can drive a vehicle thru without flats.

Well, lets stop and think a second. these are specially designed purpose built tires. they,re not designed for trucks or anthing but tractors.

If where you wheel looks like the kind of terrain tractors encounter...then yes, they'd be an excellent choice.

If not, I would guess not.

They've got other neat ones too

I've no idea how to translate those sizes though. And thos ply ratings are HUGE !! (not meaning tough sidewalls...meaning huge load carrying capacity - meaning NO BULGE)

I'd agree with Retard and others here , it's a pretty specific-use tire . Alot depends on what you want out of a tire like that . Trailored rig ? Is it even street legal , or would you need to swap all the time ?

the sidewalls are very stiff, and pull the bead off the rim pretty easy at low PSI's. seen video at big dogs of a guy loosing 3 beads in 5 minutes runnin like 8 or 10 psi in em...pretty funny..groove up some boggers

michilin makes some DOT approved ag tires for up to 55mph.

I think they come in a wide array of sizes.

If they are radial shouldn't they flex decently:confused:

If your looking for tires with a pattern like that look more toward Terra tires off of a ditchwitch, or simluar vehicle. They are not as stiff and seem to work well for mud and sand at lower pressures. Just have get a 20" rim made for them. I would not use them on rock, but if its like around here you don't see rock as often.

If you looked at the specs you would see they are 4-ply and designed for compact tractors:
SA507
A wide looking lug-pattern tire for compact tractors. Lugs are well positioned to ensure maximum tractive and self-clearing properties. Wide tire profile and thick lugs are designed to withstand tough operation on hard ground where traction and wear resistance are required.
