Thread: Cooper Discovery ATR's

That article accessed the 18" passenger tyre construction ATR's. Much lighter construction than the LT construction.

I have used LT ATR's in 17" size. Great for sand and smooth rounded gravel & excellent on road in wet or dry But found them wanting on rock, shale, rough angular gravel, and of course clay & mud.
So, they performed just as recommended by Cooper.

Just wondering what everyone else thinks of them?

Craig,

I had them on my previous Cruiser. They came with a 80,000k "guarantee" which I thought was a tall order seeing the original tyres clagged it at 45,000k. When I sold the Cruiser the 80,000k was just about up on the tyres - I went to the tyre store and they told me the tyres would be good for another 10-15,000k! I was impressed! They were rotated regularly though. I didn't do much off-road stuff so I can't comment here. But highway wise they were very quiet.

Regards, Ron

I think the correct name is Discoverer ATR

I have used them in the past but have gone to BFG ATs now. I just think for an AT rated tyre the Coopers are not really aggressive enough and they are more road tyre biased. They perform and wear well enough but so do the BFG. Not sure of price difference with the BFG.

Hi - I had them on my old Patrol - got about 75k out of them but were regulalry rotated. Great tyre overall - only problem I had was in the wet that i had to be careful about losing my back end even at fairly slow speeds round corners.

Switched to Pirelli Scorpions ATR just before I changed over to the Disco and were a notcieably quieter and gripped better in the wet. however, didn't ever really test them off road - suspect they are more road biased than the Coopers

I too have had the Cooper Discovery tyres (the older type) on a Landcruiser, like Ron, and have had good wear out of them. I found them great in the wet and dry, but not so good in the mud. Its the same old debate. You cant expect a good on road tyre to do well off road and vice versa.
My local tyre dealer has come up with the following options and prices for 18" tyres: -

• Cooper LTZ 285/60/18 - $425.00 each
• Pirelli ATR 255/60/18 - $400.00 each
• Cooper Discovery 285/60/18- $360.00 each
• Mickey Thompson ATZ 275/65/18- $500.00 each
• BFG 265/65/18 - $485.00 each
• Yokahama Geolander - Didn't quote or recommend.
• Cooper ATR - 275/65/18 - $480.00

I have ordered a set of GMAX rims through Gordon and at this stage, tending to go with the higher profile and wider tyre.
I am interested to know others opinions based on the above choices.

Cheers, Craig

From a NSW legal view point (maximum 15mm larger diameter), only the Pirelli's are OK.
The 285/60/18 Coopers are 36mm larger diameter than std fitment.
The BFG's are 39mm larger diameter.
And the Micky T's & Cooper 275/65/18's are a massive 52mm larger than std fitment.

Check legality in your state.
Also, will the larger widths & diameters cause rubbing on full lock or even on the guard?

Ignoring the legalities then:
Personally, I've used Cooper ATR's (see earlier post in this thread), BFG A/T's & The MickyT ATZ's (5 rib design).
The BFG's are great all rounder in every sense. Recommended
The 5 rib design ATZ's were disappointing due to chipping & cracking at the base of the tread blocks.

Good work sussing out those 18" options, Craig - I guess all of us contemplating the switch to Gordon's GMAX rims are wondering what tyre we might fit - and what it might cost. I'm a bit bemused about the legal sizes, though I do know (as Ducks Guts has pointed out) it varies from state to state. Interested to see Gordon plans to go to the BFG ATKOs in 265/65 size - I know he's moving from MTRs and would be heading for something pretty sturdy, but I thought he'd indicated earlier that this is the largest legal size that won't rub. Maybe that (legality of size) only applies to WA? Pity he's in Kenya at present, or I bet he'd have some light to throw on things.

Will be interesting to hear Gordons comments on this post when he returns.
