Thread: D3 18" off road tyres?

Hi All

I had one of my managers have a quick look at this today and the most important thing about tyres is the load rating (speed rating is not really a concern here as we no longer have unlimited road speeds, that I know of maybe NT still does? but...), on the bottom right corner of the drivers door is the rating plate, the min load rating that the SE (I assume it will be the same across the S and HSE, in the tyre books it is) is legally allowed to use is 109T which means the tyre options are

OE Size 255/60R18 112H
Options 265/60R18 109T

(Discovery 3 SE TDV6, 4.0 V6, 4.4 V8)

Which means all of the major brands should have a tyre to match either one of these sizes. Cooper, Dunlop, Conti, Pirelli, Goodyear etc (note the Goodyear you can also get in an ATR Silent Armour)

Cheers

Just a quick question guys.

Is 265/**/** the widest you can fit on a D3? And if they do rub, where about?

No - you can fit a 285 x 60 x 18.

Some of the guys have these in Cooper LTZ's

I like the look of these but am a bit nervous about how the extra width will be when deflated to around 20psi as there is not much clearance from the front shocks. Has anyone tried this out?

I don't think you can get them in the spare wheel space without deflating.

And even though they have LT in the tyre designation LTZ they are only listed as passenger construction not Light Truck, but their load rating is the highest I have seen available for the D3 at 120 and a speed of S which translates to 1400kg and 180km/hr, well worth considering if and when QLD changes to the national code allowing 50mm increase in tyre diameter not the measily 15mm at present.

Hi chuck, has anyone had any problems with rubbing ? given the extra width. They only just fit fully inflated how are they with reduced pressures

I believe there is rubbing on certain models, (08 onwards I seem to remember) and beware the rear air conditioning pipes. However, I think the slight rubbing is more cosmetic then mechanically damaging.
