100 Series wheel spin causing tire tearing/chunking?

[r2m]

So the advice for chunking tires is to buy 18" steel wheels and swampers? WTF

Get the Tundra 18" alloy take-offs and use them for the road... They aren't that bad looking of a wheel.
Use the 16" LC stock wheels for wheeling...

I noticed my 285's BFG's chunking after our Big Bear trip (Gold mountain).. Mainly the front tires.

Same here on the front, probably due to the front loosing traction and spinning much easier than the rear just like I thought. Since I'm rotating all my tires at regular intervals, I have 5 tires that have minor chunking.

And I guess it's not entirely the Coopers fault, since you say your BFG AT also chunked, which from what I understand are a pretty hard compound.

I think larger lugs like the KM2 without siping will help stop most if not all chunking?

I am not sure that is the case. Every set of tires I have owned on 4WD vehicles in the past 20+ years has ended up chunking. IMO, the chunking happens on almost any vehicle that is driven on rock surfaces that has broken edges (not large expanses of smooth rock like areas of Moab). I am basing this on experience with the following tires on both locked and open rigs:

• Dunlop Mud Rovers
• BFG ATs
• BFG AT K/Os
• BFG MTs
• BFG MT KM2s
• BFG Rugged Trail
• Goodyear Wrangler AT/s
• Goodyear MTRs (original directional pattern)
• Goodyear MTRs (2nd generation)
• Interco Swamper TSL
• Interco Swamper TSL Radials
• Interco Swamper TSL/SX
• Interco Swamper Trxus MTs
• Cooper Discoverer STT
• probably some others I have forgotten about ....

I list these simply to point out that every tire I have used on a vehicle driven in broken rock has shown chunking ... and I am fairly light on the loud pedal (though I have been known to abuse it :whoops: ).

The tires that chunked the worst were on a dedicated trail rig with all of 45Hp at the rear wheel (Suzuki Samurai). It is more about where and how the rig is used than tire type ...

As always, YMMV

All tires will chunk eventually if you do any real off roading. Kind of like brush strips along the side of your rig. If you are serious about wheeling, don't worry about the tires chunking and the other battle scars of wheeling. Wear them proudly!
Unless the chunks out of your tire are becoming unsafe.

I was wondering if I am alone on this or not. I have been getting some tearing and chunking on my tires and I think it's due to the tires spinning over rough and rocky terrain. I'm also someone who is very, very gentle on the throttle. I try to avoid wheel spin, but sometimes you can't and actually need it for A-trac.

I don't believe the tires themselves are entirely at fault. I'm thinking its due to the characteristics of the 100 series to constantly lift its tires and the A-trac needing wheel spin to operate.

Anyone else experience this?

I'm really surprised at the responses here thus far. My own experience is very similar with above, with a strong correlation to usage of atrac. It requires spinning tires to work.

Once I installed lockers and started using them, all the chunking issues I saw with tires went away.

Just my 2 cents...

You're saying chunking is due to A-TRAC.... We're assuring you that its not

I am running much heavier duty Toyo MT tires now and starting to see some chunking again.

Can't entirely blame Atrac this time since it does not activate nearly as much as it did when I was running the other tires. These Toyos are like glue on the rocks and rarely get much slippage. I guess I'll blame the weight of the truck and the sharp rocks I'm always during over.

Just thought I would share some pics:

Call the folks that made the tire. That doesn't look normal.

Called Toyo Tires for the hell of it. Most worthless customer service I've ever seen. They were blaming me for the chunking because I run "way too low" air pressure in my tires on the highway.

I run 40-42psi.

They said I "must" run 47-50psi. What a bunch of crap.

I'm curious if your Toyos MT's were made in Japan, USA, China or ?

All 5 say made in Japan
