I am in the process of buying a 3.0TD Patrol and have the option of putting 285/75/16 Cooper A/T on it. I have run them on a 4.5 GU Patrol before no problems but just need to know if anyone out there has them on their 3.0 TD and if so any probs with comsumption, loss of power (bigger tyre to turn initially) and speedo throw out.

Love to hear from anyone

Mick, FWIW, I just put 265/75/16 BFG AT's on my 3.0Di Auto. Without getting the calculator out it's probably about half way to where you are going from the standard size. Speedo still underreads a little at 110K. I have not noticed any performance difference, the auto would probably help there at take off. I did notice more pedal pressure required to stop.Regds

Mick I to have just put 265/75/16 A/T's on my land cruiser and Im very happy with them No noticable difference. Very little difference in speedo. I went for the 265's as the dealer told me they are a tougher tyre due to the fact they have a 10 ply construction, were as the 285's have 8 ply.

Mick I have just done a quick trip to the Cape and back on 265-75-16 MT on a GU and found them to be a perfect size, only 1k out with the GPS.

They performed better in the mud than the 32-11.5-15 MT I had on a previous vehicle, and on the highway at $1.30 sat very well.

My 2nd set are Yoko Geolanders A/T + 11 in 265-70-16 for aroud town, slightly wider and handel a bit better in the wet.

I run 285/75-16 Cooper ST's on my 3.0 tdi Auto Patrol. I would assume that diameter is the same as the A/T's due to the same manufacturer.

I also have the original 265/70-16 Bridgestone as well as a set of 265/75-16 Bridgestone originally fitted to a Patrol Ute.

With my particular vehicle my GPS tells me that with the 285's my speedo is 99.9%
accurate, the 265/70's 94% and the 265/75's 97%. I don't think you can necessarily count on this degree of accuracy, as my brother has an identical vehicle who's speedo was over 10% out (before Nissan fixed it) with 265/70's.

I notice no difference in performance under any conditions, however there is a dramatic drop off in economy under moderate to heavy off road conditions. I do not keep records on fuel consumption, but on a recent trip to the Cape, my fuel usage was higher than a Toyota 4.2 turbo 80 series and lower (not by a big margin) than a 4.2 petrol 100 series. Economy around town or on the highway is little different regardless of what tyre I have on at the time.

Hope this helps

I have never taken it to them with the 285's on, so I suppose I have never put them to the test. By the same token, I would have a good argument in my favour in that the speedo is accurate with the 285's and not so otherwise.

If there was ever a problem, it would be up to them to prove that the tyre size was the cause - or in reality, for me to prove that it wasn't I suppose.

I am not sure about the 285's, but I know that our local dealer will readily fit 265/75's on Wagons as part of the initial sale.

Unless I am a bit lazy, I change to the 265's for around town, so that is what would be on the vehicle whenever it visits the dealer. In fact I can recall it going to them on one occasion with 265/70's on the front and 265/75's on the rear, and if they even noticed it, they certainly didn't mention it.

If you think this might be an issue for you, then I would certainly check the situation with Nissan - or have a second set.

I run the 285 St coopers on my 4.2 turbo and did find there was a noticable diferance in low down torque when pulling a 2 ton boat out of the water on the boat ramp. Fuel economy suffered a little bit but not much. Other than that not much difference. Excellent tyre except for chipping and at the moment should get over the 80 000klm as per warrenty.
