gday bernie.
tyres have been done to death here but ill tell you what i know.
i sold coopers for 5 years.well over 1000 sold
about 500-600 st in different sizes only 1 claim the guy drove on it flat.
but cooper did a pro rata claim any way.
now when you buying tyres theres a few things they should be asking if they dont find another dealer simple as that.
(1)what sort off driving do you do.road/sand/mud/rock climbing ect.
(2)if you do go off road do you know about using different tyre pressures for different terain.
(3)make sure you bring them back for rotation every 8-10000ks.(should be free)
ok ill explain
(1)if you spend most of your time just on the road h/t tyres.
now if you do go away every now and then for some fun it goes like this.
most time highway/ weekends of road in dirt/sand h/t
most time highway/weekends of road in dirt/mud s/t
not much highway most time in the mud/rocks stt.
(2)due to duck season coming
ive decided to hide out
love jemima puddle duck
back after the season

(2)ill work of my tyres common size 31x10.5x15.
on highway about 32psi on h/t s/t and 28-30 psi stt on the road.
on the dirt or in mud about 20-25 psi(s/t)
in the sand 15-18 psi.(h/t)
rock climbing about 15-20 psi (stt)
ive read a lot about s/t losing lugs ect but in most cases its drivers
(a) having the wrong tyres for what they need to do
(b)having the wrong tyre pressures for the job.
i heard about a bloke having a whinge about not getting many ks from his cooper s/t but what wasnt mentioned is the tyres had about 50psi in them/fully loaded 4by/on a dirty old rocky road.no tyre will live.
s/t arnt designed for rock climbing thats why theres stt.
now pick any lugged tyre and climb rocks with 30odd psi and spin the wheels and lets see lugs ect not rip off.
(3) importance of rotation/10000k check
(a)4bys are heavy now picture a left hand turn.basically a 90 degree turn
think of all that weight being put on the left hand front tyre(thats why most front left tyres scrub out on the out side)
now a right hand turn nice easy turn arnt they still a 90 degree bend but not as sharp.thats the reason behind the importance of rotation and also gives the tyre guys a chance to make sure the pressures are right bye looking at the way they are wearing and adjust if needed.
noe theres going to be people with different opinions thats all right.
im just giving you my opinion fron years of tyre fitting and spending some times an hour talking to the customer about what they really need to fit.
as i said fit the right tyre for your needs and you shouldnt have any problems.
cheers

OK Diamond i know its been done to death but still undecided between 285/75R16 coopers st and 265/75R16 coopers st as a good all round touring tire for Australia, bearing in mind that the 265 has a 10 ply and the 285 8 ply the 265 also has a high KG loading by about 50KG at the moment have on BFG 275/70R16 and do not like the bulge in the wall at all although would think the tire would be alright for rock work, we need to be able to fit a good all round tire to both the patrol and Camper that will go anywhere, i note that Ron Moon has said that he will change from the ST to the STT next time i would have though that would have been a bit harsh for the work that he does, unless he is in a lot of wet weather.

Paara, if it's rock-work you want to do, don't but the Cooper ST. They are great on the tar, dirt, mud and sand but are not designed for rocks. Smile, you're on ExplorOz

Hi Rohan, what i ment to say was that i fitted the BFG for NZ as we have been doing a fair bit of river work and thats where the rocks are and the BFG have been good for that, soon the rig will be back in Australia and will be doing the trip around so am looking for another tire i note that you have gone for a real narrow tire which is what i am thinking about "265/75/R16 both for the side wall strength and the sand issue how do you find yours.

Good to see you are on the right side of the bridge

Para, I'm a firm believer (old school, I guess) that taller, narrower tyres are better off-road. having said that, my choices were a little limited anyway. The Pathy comes with 245/70/16 and I had the choice of going for a 265 and sticking with the 70 profile, or sticking with the 245 and increasing the profile to 75.

I have found the stiffer side-walls provide better cornering and a more "solid"/direct feeling through the steering wheel when on the black-top. The contruction, and "straighter" side-wall is supposed to make the tyre less susceptible to side-wall staking, but even these 10 ply Coopers still bag quite a bit below 22 psi.

2 other Pathy owners, having also recently purchased the same tyre, have suffered some lug damage. I haven't, despite some pretty rocky and steep firetrails and river beds (but I don't go rock-climbing).Smile, you're on ExplorOz

Rohan, thanks for that they tell me that coopers are bringing a new tire out this may called STC and it is suposed not to chip as much as the STT might be worth a look at the lug damage comes from the design of the tire where it lets the water out " or so i am told" i am with you on the taller tire all the way.

The STC is already available. It uses a different (softer) compound. The theory is that the softer rubber will yield more rather than tear. It is principally designed for use by mining companies, farmers and those that spend 80% of their time on outback dirt roads. The wear rate will not be good on sealed roads.

All this comes "straight from the horse's mouth" - Coopers.Smile, you're on ExplorOz

Both the ST's and STT's look the goods. Unless your doing a lot off Offroading, and serious stuff at that, the ST's are luggier (is that a word!?) enough to get the job done and will be cheaper to buy AND last longer.....less highway noise too. I tossed up between the ST's and BFG AT's and ended up going BFG. The price was the only factor in this decision, $288 compared to $220, no contest.
Cheers, Mark.
