Thread: Cooper AT/3

I have now towed our 2.5 ton van twice with the AT3's on and while the pressure only goes up about 6 psi after an hour towing on the freeway it doesn't tow anywhere near as stable as with the STT's.

I took a gamble with getting a tyre with a 109 load rating knowing that I would be towing a heavyish van and for towing our van it hasn't paid off but they are still excellent for norml driving.
I would hazard a guess they would be fine for a camper etc but I don't feel for me anyway they are good for a van that has quite a bit higher centre of gravity and a greater pendulam affect.

Now I would bet this only applies for the 18" AT3's with the 109 load rating, the 17's have a heavier load rating.

Anway I will now be going away over Christmas with the STT's on rather then the AT3's.

cheers,
Terry

I know how much trouble you had with your coopers, me too. But i thought i might give the new at3's a go since i live in a capital city and can screw them for warranty. In person the coopers look like they would be pretty good in the ruff stuff. There is just stuff all selection in our sizes. Im to scared to go anything thats illegal, seeing that this disco cost me more than the old weapon

Have done a bit on these new GG AT2s, so far I'm impressed, quiet and good grip on and off road.

Here's a pic of the new tread pattern

Neil I have had 2 warrenty claims honored by Cooper Tires.

Baz.

I know of three failures with Coopers. One resulted in the rollover of the vehicle. One of the others took the vehicle off the road, but thankfully it didn't hit anything. And the third...well, the driver had just finished telling me about the first two, when the tyre delaminated.

Just dropped down from 20 inch Continentals on my 03 rangy to 18 inch Cooper A/T3. Boy thay give a good ride. Incidently whilst on the 20 inch the front brakes squeaked a lot. Since going to the new 18 inch rims and tyres, no squeak at all. Interesting?

I'm with you Gordon. Prior to the D3 & D4, I had travelled around 160K in total on Copper AT's (old tread pattern) and never had a problem. They tend to get clogged in thick mud, but then again, they are a AT tyre.
The only negative I had with them is that they used to flick stones.

I have now done 10000 K on my AT3's and are very happy with them. Have always run BFG except for one set of Coopers years ago which I hated but as BFG's were not available and I was going away I fitted AT3's and they are very good on both black top and offroad and with a van on for around 3000 they still impressed.

Funny enough, I changed to Coopers because the BFG's let me down too many times. The last was when I had to brake hard in the rain coming up to a round-a-bout, towing a trailer. The tyres let go and I ended up all over the place.

Are the AT3's really quiet or quiet when compared to the factory garbage they come out with? Also have you noticed any change in the fuel ocnsumption? cheers
