how many ya'll runnin wit mild to moderate crackin.

prone to blowouts?

talkin mud tires btw, guessin anythin INTERCO got thicker sidewalls and can still take a beating.

or who gets rid of em when dryrot starts?
who thinks it all aint that bad?

..shoulda started a poll prolly
 
Um, hopefully you aren't talking about running them on the street. To a point, they would be fairly safe on the trail still, but definitely not on the street.

Pics of said "mild to moderate" cracking?
 
i ran my stock radials until they died. just make sure you have a spare and the tools to change a flat. i wouldn't think a dryrotted tire would give you a blowout, but others can give input on that. it'd probably start leaking before it pops.

interesting point of view.


and yes, the rig would be driven to the trails about 1 mile away.
so it will see a little street.
my tires i have now do not have dry rot, just ones i am maybe going to buy. they are 44's with tread left mounted on black steelies for $400.
they have dryrot, but for that deal, it was worth me posting a thread to get input/experiences
 
The tires I had on my old Jimmy were from the early 80s and had dry rot cracks all over in them. I never drove it much because I was afraid to, but the guy that bought it from me ran them on the highway until they were all bald. They never leaked or blew out.

But I still wouldn't go buy dry rotted tires.

The cracked section is most usually just the outter superficial rubber layer that protects the bands underneath. I've run dry rotted tires on the street/highway without issues... I'd say unless you see the cords there isn't a huge issue.

I'm sure some will hang me for the above statement... BUT I have a real good buddy in the tire business that doesn't seem to think it's an issue to run them (if the cords aren't showing). If you can afford new tires then that's obviously the best route to go...
 
This tire is from 1954 and the worse dry rot I have ever ran. The tube popped and sounded like a shotgun. Tires with cracking should not be ran over 20mph IMO, at higher speeds the air inside will expand, causing the pressure to rise and the tire may blow.

i might as well add that i only ran dry-rotted tires because i was in school and had no money to call my own except for what i could earn from my parents for labor. and that went to gas and food. i now have new-ish tires that are probably only a couple years old. if you can find a tire place that will sell you take-offs that are in good shape, do that. i got mine for a little over $400 installed for some 31's in great shape. plus it wasn't any hassle for me.
 
Having similar issues on my old A/Ts... so far no problems but I would like to replace them in the near future.
 
My 38.5 SX's are pretty rotted... I grooved them and now they are crazy flexy...:D

My rig only gets driven on the trail, so I'm running them until they don't run any more...

Post a pic of what you were doing when that happened...:D
 
I think you should be fine as long as they're not too old and you don't let them get too low on pressure. Also, I would avoid airing them up a whole lot too. My father-in-law loves to run old dry rotted tires with the max pressure that it says on the side wall to pull his trailers with. Blow out city on the trailer and tow rig. I don't think dry rot is as bad for bias plies as it is for radials though.
 
around here most of us have run dry rotted tires. usually the best deals are older tires with still good tread. our motto is as long as they hold air then its good. we all run interco tires. but ive seen people still running gumbo monster mudders that were waay worse than anything ive run and they were fine, and i heard someone say they stopped making those over 10 years ago. not sure how true that is, but if so thats a good testament to dry rot
 
Not sure how much it matters with mud but in the rocks old, dry tires don't hook up anywhere near as well as newer ones.
 
All bias Swampers i've seen have atleast a few cracks in the sidewall.
 
I just changed my trucks badly dry rotted 245/75-16's in the rear,the cracks were wide enough to let a nickel fit in and you could see the cords..one tire had a "flap" hanging off it on the inside ,where I rarely look!..good thing I dont go on the highway much with it and it is used mostly to plow my driveway!..:eek:..

..the front ones are Michelins and have deep tread,but I see the area where the tread rolls over to the sidewalls are cracked on those too,so I'm not going to be speeding in it anytime soon..I have had the entire tread come off in one peice at 65 mph,and it does nasty things to your undershorts..

...one tire that happened too on my '66 Buick Wildcat,I drove home on,12 miles from where it happened,limping at 45 mph--the cars passing me were blowing their horns and passengers were yelling and pointing at the tire,which was throwing sparks like crazy--it was a steel belted radial..when I got home,it still had 32 lbs of air in it!..looked like a huge wire brush too!..had to wear welding gloves to take it off the car,and no gas station would touch it,to mount another tire on it..had to do it myself using a bumper jack to break the beads and pry bars..was like touching a porcupine !..

I run dry rotted tires on my lawn tractors,but dont like using them on street driven vehicles..though when I was a kid I'd put radial tubes in tires I found dumped in the woods and rarely had any blowouts!..
