Hi Savvas
Checkout the following site http://www.coopertires.com.au/tyres/index.htm
The decision on tyres is down to what you use the vehicle for. I use A/T because mud is not my interest and I use them fro Road and of road and they have been great

Savvas,
Go to the website and check both tyres out, they are chalk and cheese, totally different. I run a set of LT285/75R16 SureTracs on my 80 series petrol (LT of course stands for Light Truck these are optional and you will have to ask for them) I would spend about 90% of the time on the black stuff but could not be bothered with changing tyres every time i wanted to go bush.
SureTracs are slightly noisier than BF All Terrains but not as bad as BF Mud's, they handle excellent on the road wet or dry and are outright weapons on dirt. Cooper A/T's would be quieter it depends what your poison is but with 13mm tread depth and 80,000km warranty you could'nt go wrong with either.

Cheers Ash

Theres a write up on the ST's and from all reports they are an excellent tire.

YMMV

One difference that was pointed out to me was the difference in the chip resistance in the compound. A recent trip through the Pilbara clearly demonstrated that point, when I compared tyre damage on vehicles at several camp sites.

The chunky tread on the S/Ts are quite noisy, but after that trip, I am happy to have them on my vehicle.

From what I understand the AT has been designed as a tyre that is fundamentally a road based tyre, though reinforced and more aggressive than a highway tyre for occasional off road excursions. It really is designed for the typical recreational 4WDer. It has a tread design that is quiet, sipped for good wet bitumin grip and long wearing. The ST on the other hand was designed more for the outback resident. With so many of the roads being dirt and so much time being spent on these roads the tyre designed for these conditions were really the Mud terrain tyre. If you look at what the manufacturers state these are for 90%(ish) off road use. The problem being how do you define "off-road"? Is it Mud, dirt trails, rock hopping etc - and all of these are off road, though the requirements in the tyre needed for this is very different. The design of the Cooper ST, from what I understand, was to provide a good outback road tyre that on the otherhand performs better than the full mud on dirt roads. In reality, the ST could almost be a cross Mud terrain tyre and All Terrain tyre. It does has sips to improve wet weather grip, unlike the Mud tyres, and similar to All terrain tyres. It is also designed to hang together in rocky country. Regards Slunnie

I went through the mill a couple of months ago on what tyre to fit for a good all round tyre , that would lean towards being a good off road tyre but still be alright on the road. After the responces on the foram . thanks to all . I put on a set of cooper S,T, s 10 ply on my toyota 80 series . I moved off split rims to solid rims . Most say that the

SORRY ABOUT THAT I was cut off ..../ most say the S,Ts are a bit noisey but I find them alright Have just done a trip to vic high country and found them to be great. I do do a lot of sand driving as normal the tread will dig you down a lot faster than a highway pattern but if you let them down as you should they are great . have only done 5000 kms so far cooper back up there tyres for 80,000 kms so long as you rotate them every 10,000 kms I am very happy with cooper s,t . If you do mostly highway Iam sure all terain would be alright.

Hi All
I have been looking at fitting a set of S/T's to my Disco, only problem is they don't come in an LT in my size 235/70 16 and are only available as a passenger tyre which I believe are only a 2 ply. Does anyone have any experience with the passenger rated S/T's ? i'm just wondering if they are going to be good enough as I do about 50/50 on off road.
Cheers

savvas - i'm onto my second car with cooper a/t discoverers running 285/75/16 on alloy wheels on my gu3 and could not praise them enough - the last set we had on the car for 40000klms prior to selling and wear was fantastic - blacktop grip in dry and wet was fantastic and excellent off road too with a trip to the kimberleys via tanami and one to cape york from melbourne - when we sold the car i estimate there to be at least another 10000 to 20000 of high quality wear available (i'm fussy) - hope you enjoy yours as much as i do mine - regards tim

I have a set af ATs on my patrol. Best tyre I have used. Great on road and good off road although if you do a lot of mud driving I would go for the STs with there more agressive tread pattern.
Regarding the warranty I am pretty sure that you have to go back to place of purchase and get a wheel balance and tyre rotation every 5000ks?? or warranty is void. Also applies mostly to purchases in metropoliton areas. This may have changed but I am pretty sure this was the case when I purchased mine.
