Yes it's that T word again.
I've been looking trough the archives with not much specific to be found.
I'm looking at a new set of Cooper ATR's or ST-C's. (yes I do realise they are different things and therein lies my quandry)
All tyres are a compromise, therefore do I fit ATR for blacktop performance and quiet ride with a limit on off road ability, or do I go for ST-C for better off road performance and put up with higher noise level on the blacktop.
I'l be really interested in anyone's experience in going to ST or ST-C's from any All Terrain tyre firstly and spcifically in relation to the noise factor, secondly other performance considerations.
I'd also like to hear about ATR's or the previous AT in off road situations.
I am limiting my choice to the 2 types of Cooper as I need 265/75/16 in a 123 load rating and there is not a hell of a lot of choices around.
Cheers
Chris

Hi Chris,
I have Cooper ST's on my GU, which I have had from new (only did 15kms on the original tyres, from the dealer to the tyre
shop). Prior to that I had BFG TA's on my 80 series.
The ST's are definitely noisier, if you wind the window down and listen for it! But with the radio at normal level and windows up, you would never notice the difference IMHO.
I have now done 65,000kms on the ST's with ~9mm of tread left from the original 15.5mm. As they wear they are getting slightly noisier, but nothing I would be concerned about.
All tyres choices are a compromise but I am extremely happy with the ST's, especially the off-road grip and am happy with my decision. Would definelty do the same again.
Cheers
Captain

I currently have the Cooper AT’s, and they have preformed
well I think for what they are. On road and in the wet that are good, on Gravel, rock and sand no problems ether, They are not too spectacular in mud, as would be expected being an AT tyre, but that being said they have pulled me throe every time with some right boot input and perhaps exerting a little more sideways than desirable at the time.
Am about to Upgrade to the ST’s at the end of the month, the AT’s currently have 47,000k on them and still have a nice amount of tread left, I would also like to Say that I have abused these tyres somewhat and they have a few Battle scars to show for it, but thay have never let me down.
Cheers.

Chris,
You may also want to consider the Goodyear Silent Armour - come in 265/75 with load index of 123, and they are the quietest tyre I've run on a 4wd. They claim to be very puncture resistant, with Kevlar etc Just have a look on the Goodyear website.

Thanks Phil
Interesting suggestion, especially as the MTR seems to have quite a following amongst people here. From the pics it looks a bit like the Silent armour is the son of MTR in tread design.
How have you found them off road and have you experienced chipping on the rears on sharp rock gravel roads?

The MTR deserve their strong following - I had a great run out the MTRs I had before - and they were used exclusively for offroad trips over a 2 year period. I bought the Silent Armour this time because I wanted to try them and they had the same puncture-resistant technology of the MTR. Every tyre had a downside - with the MTR, they make a bit of noise as they wear, and they consume more fuel than other AT tyres - thats simply the price you pay for a strong offroad tyre, with thick sidewalls.
I've only done 5000k on the Silent Armours but took them into the north
Simpson Desert last month -
Madigan Line and
Hay River. They were fine. There was no chipping from any of the stony roads, which normally cause chipping on the Cooper ST and BFG ATKO tyres. We got one puncture between two vehicles that had the Silent Armour. My fuel consumption was a bit better than I've had with the MTRs and the Silent Armours didn't need to be aired down as much in the sand.
So I'm happy with them - In the 79series, they are really quiet, and ride
well. Thats just my experience to date. And I have to say that I'm satisfied with most brands of tyres I've had over many years.
Cheers
phil

Chris, I bought my Landcruiser with Pirelli Scorpions on it (about equivalent to Cooper ATR's, 270/65R16). No complaints off the bitumen but slippery on dirt. I'd always lock the hubs on dirt, had to drive carefully if it was wet.
I changed them for Cooper ST's (285/75R16). Much better, no complaints. Occasionally drifted about on the dirt but locked into 4wd the car handled ok. Some chipping and cracks at the base of the tread blocks but nothing worrying. A big improvement over the Scorpions.
I've since gone to STT's (305/70R16) and I don't lock the hubs anymore for most short runs on dirt, 2wd is generally more than adequate, but I'll hit the rear difflock if I think there's a chance of wheelspin. Car doesn't drift about so much either. A big improvement over ST's.
My experience is that the STT's are worth the extra cost in treadwear etc, if any. I wouldn't recommend anything less than ST's on a car that may see a fair few
miles of dirt. Casper
