Hi to all, just wondering what people think about coopers on gibber rock tracks?
i have been running "discovery S/T 31x10.50 R15LT" and thought they were great until used on gibber roads last year, had hardly worn for 30000km then 400km of rock = almost un roadworthy!!!!!!! also i see they have "chip resistant" versions available but not in 15 inch as far as i know, are these any better? What would be your choise for these conditions? i must say however, even though wore buggery out of tyres i didnt get a flat except for 2 slow leaks, where i did seee lots of tyre repairs along the track.

On previous trips we too have had vehicles in our convoy using Coopers that lost alot of rubber on gibber as well as BFG All Terrains. Several similarly loaded Cruisers running MTR's had far less wear over the same tracks. As previosly stated all tyres suffer damage on outback roads but the MTR's seem to be one of the better all round performers. I asked at a Broken Hill tyre fitter what brand most of the locals used on outback roads & they said the 12 ply Dunlop Road Grippers were by far the favorite. (Make of that what you will)

Cheers Craig...............
285 MTR's
255 BFG MT's
235 Road Grippers.

My Firestone RMTs didn't, the Coopers after a similar trip looked like they had been attacked with a gouging chisel!

Surprisingly many of the road tyres are better than the AT and MT tyres. Never seen a GrandTRek suffer from chipping on those roads (but yeah its easy to destroy them).

Worse tyres I've seen on that sort of stuff are the Cooper S/T, and BFG ATKO.

Of the more aggressive tyres, Goodyear MTRs fare well, BFG MT are not too bad

Hi Dingo

I was speaking to staff at one of my Central Qld mining customers last month, who said that Coopers didn't perform well on site (obviously all dirt work). They got a better run out of Bridgestone MT's, the more common tyre on their site. I think most are 235.85x16's rather than wide.

I had my first Cooper fail at over 100,000km up that way, and the tyre shop also mentioned they weren't the as good as they should be for Central Qld heat etc. Naturally, I can't complain about my experience.

The second set of Coopers were chip resistant compound, and they wore a lot faster than the normal Coopers. i guess it all depends on the application.

Thanks for that brd
i was considering buying 16" rims and trying cooper chip resistants but sounds like i still may be disappointed, i am very happy with my normal coopers around the mallee and murray country where i live but for long outback trips i feel they are not the answer.

Hey Crackles , I'll tell you what I make of the tyre bloke in Broken Hill said, he and the next tyre dealer will say the same thing.
I've been running Road Grippers for 22 yrs (450,000K ) and 1 puncture, 1 staked (off the road )
At home the 265 muddies go back on because they perform better and wear better but the Grippers for outback trips because they have proven themselves time and time again and they are easily bought and splits are easier to fix when out and about, that's what I make of that.

Hey Harry , Probably a lot to be said for running split rims. i used to run them and must say didnt have much trouble, they are a bit more unstable on the bitchumin when towing i recon and have had a few flats, did 2 in one day on bitumin once and 3 in a week around town, but some may of been "adventurers"?
not sure if the road grippers were 12 ply?????

G'daye Dingo,
I have never seen a 12ply, as far as I know they come in 8ply, that is the one's that come out of Japan. They have an F stamp and they're the only ones I will use.
The Adventures are OZ made and don't fair anywhere as well as the true GRIPPER.
If you say they don't handle as well , maybe your running your pressures too low. I have mine at 45 rear 38 front and that works well when towing as well. Put 42 in front when towing.
Have a good 1

I've just got back from Alice via Great Central road and Mereenie loop road. All up about 7000 k with approx 4000k dirt. I'm running 245/70/17 cooper ST. I had one do a side wall coming into Glen Helen. Only tyre on the trip for three vehicles. The others were running Cooper ATR and Trailcutters. Pressure was 38 psi on back due to load of trailer. Speed avaraged about 80 kph. Total ks on tyres is about 10k and they look worn but there is no chipping and no torn lugs. Jury is still out on whether they are going to be replaced. Great central road was ok with some bad patches but not a lot of stone. Mereeenie loop was rough and stony.
