small change in tyre size - any issue?? [Archive]

Hi all,

Local tyre dealer checked his 'book' and advised me that I can have Coopers AT3. They are 265/60/R18 so an increase in width from the 255 dealer boots that they issue us with.

Will there be any issue with this? Pressumably a slight increase in fuel usage. I'm guessing it will still fit in the spare bay under the rear?

Thanks

I had 265/60R18 AT tyres on my D3 for 4 years - they were great. The speedo becomes closer to the true speed and the spare fits without any issues. It is also a legal size in NSW/VIC/etc, so no worries. :cool:

I have that size and model Cooper tyres on my D3 and they are great (so far).

Thanks for the replies. Looks like I'll be getting them.

Hi Ozzy,
I've got them on my D3 as well, pity you aren't a bit closer I'm looking to get rid of them in favour of some GGAT2's. No matter. I have no complaints with the size of the tyres the Coopers I have are just a bit light duty for all the fruit I have on my D3.

Was it the AT/2 model GG's that Redback had on his D4 for his christmas trip?

If so might be an idea to talk to him first before buying a set, three of his brand new GG's failed quite badly on their first outing. Haven't heard of any new Cooper AT3's failing off road to date, so maybe the General Grabbers might not be a better option.

cheers,
Terry

Yes the GG AT2s are not a LT contruction tyre, they are not design for offroad and do stake easily, stick with the (OMG I never thought I'd ever say this:eek:) Coopers if they have been good!!!

I'll be fitting 265/65R18 to my D3 when they arrive. As far as the speedo accuracy goes: there is a function in the satnag screen settings that is for calibration after changing tyre sizes. At least I think that is what it is for, because that's what it says on the screen :cool:.

I used it recently when I went down to 60 profile, the speedo was accurate beforehand, and after pushing the button and driving for a bit I checked and the speedo was again accurate.

Would love to see a pic.....I can only find BFG in this size. Would be happy with those anyway, but I am a Cooper fan (three past sets have never let me down), and they do make that size but apparently don't bring to Australia. It seems that this size is quite rare....could be a worry if both spares are unrepairable in the bush.

It has been suggested that they will scrub on full lock....be keen for you to confirm this. Extra rubber and 1.6 inches higher would be nice. Might cure my sand problem.

I'm to not sure BFG A/T's will cure sand problems.

I don't think the coopers are LT construction either:(

I need more flotation to handle the weight. This has been the only let down with my D4.

Correct 18" Cooper AT3's aren't LT rated, they have a 109 load rating which is ok at the lower end for D3's.

So the Cooper 265x60x18" AT3's haven't worked for you in sand? I haven't been anywhere near sand with our D3 to know how they work in it. However they do bag out quite well though for a fairly low profile tyre when the pressure is lowered.

Re the BFG A/T's in sand nearly everything I have read on here, from memory, has indicated they are one of the worst tyres for sand usage. Still my memory might be failing me.

I had MTZ fitted in 265/70R17, the same rolling diameter as the 265/65R18, and I think there was a little bit of scrubbing initially. The new tyres are still in transit from the US, should be here next week. I'll put up pics when fitted.

Here is a pic of it fitted with the MTZs.

According to Coooper's website the new AT3 265/60/18 are passenger with load rating 110T (as in 1060 kg's per tyre?)

The GG AT2 255/60/18 is not light truck either with only a small increase in load at 112H (1120kg)

To get light truck spec for my D4 I would have to got significantly out of manufacturer wheel specs ?

Hi Terry,
The Cooper HT plus's I have on my D3 have a load rating of 114T which was the best 18 inch Cooper rating I could find at the time.

Thats interesting, before I bought mine several months ago I checked the Coopers website and it had the 18" AT3's with a 109 load rating.

I will check the D3 when I get home, I won't be unhappy if they are 110's, not that it makes much difference, from memory about 30 kg per tyre.

Sorry Nomad I took it from what you said originally that you had AT3's on yours not H/T's. ...:)

Did a lot of soft sand work in the D2 with BFG A/T's,never had any real problems.
I am looking for a LT for the D4 in 17',and will probably go the BFG again,so will be interesting to see how they are in sand.

I only have the factory tyres.....I need a second set so looking at the 265/65 18 bfgs. May end up with the slightly smaller coopers though.
My brother in law has bfg at's and they are perfectly find in soft sand....if around 15 psi for the soft stuff

OK we have decided on what are doing and have purchased a set of 17" rims, ordered the wheel nuts to suit from the US and had LT265/70/17 Kumho KL78s fitted to them.

We did look at the 265/65/18s, but $500 + each is highway robbery and if you get a flat, some how I reckon you will be waiting a looooong time for a replacement

We are just waiting on the wheel nuts now and we can fit them up.

They almost the same as the standard 18s on our D4, Graeme has the same rims.

My apologies, its taken me several days to check the Coopers for their load rating. From what I could see I think (without my classes on) they are stamped as 110's not 109's.

When I originally looked at the Coopers website to check out the specs on the new AT3's just before I bought them several months ago I am positive it said 109 not 110 as it does now.

Do these have the same size hub hole as the disco wheel?

Yes they do, there are 3 designs from 3 models of X5 that will fit the D3/4, not sure about the RRS though, Graeme might know, there is a set of 4 from an early model in the Markets that will fit.

Yes they will always be cheaper on Ebay, those are the most popular ones you see, the ones Graeme and I have are not as common and are now fetching a bit more than they used to be, there are heaps of them in the US, but freight is a killer.
