Tyre size

[Grant052]

Chaps, I'm currently running Pirelli Scorpion ATR 255/60R/18s on my Disco 3 and thinking about putting the D697s on BUT they aren't available in 255 18 inch, only 265.
I spoke to a bloke at Bridgestone and he said I could have all sorts of problems if I fitted the 265s.
What's the general opinion, stick with 255s or move to the 265s?

Many members of this forum are running that tyre on 18's.
I have ordered a set of GOE 18 inch rims and intend to put to put the D697's on.
This is a on a D4 not sure about a D3.
Cheers
Tony

No problem what so ever as you are only going larger marginally.
( As long as you are changing all the tyres)

As the others have said.
I am running Yokohama Geolandar AT/S 265/60/18 on my 2008 SE TDV6. They have been on for about 20,000km. The only difference I can see is they make the speedo more accurate:), and give me a bit more sidewall.
No problems. Many people are running the D697 and I probably would have to, but I got an exceptional deal on the Yokos.

A small reduction in fuel economy will occur...use a touch more fuel.

My 285/60-18 use pretty much spot on an extra litre per 100, then the factory 255/55-19....taller and much wider.

A Wider tyre has a little more resistance, and a taller tyre needs a touch more effort to turn them.

Just like Brett says, there should be limited affect.




There are plenty of folks on this forum running 285/60/18 on their D4s.


Occasional scrubbing is the only issue I've read about.

If 285 x 60 x 18's fit albeit with a little rubbing does anyone know if 285 x 50 x 20's will fit on genuine D4 rims?

[rufusking]

Hmmm, 10% less sidewall = 28.5mm but add 25.4mm increase in radius. It's only an additional 3mm but it was marginal to start with. Mind you these are theoretical figures.

[gghaggis]

On the std rims, the 285mm width will come _very_ close to the front control arms.

Hi Rich,
I have bought a 2010 Disco 3 and am looking at putting the D697's on my Disco 3 as well.
It currently has Wrangler 255/60-18's on the back and Continental 255/60-18's on the front. The Continentals are still in good condition.
You commented that it would be fine to change to 265/60-18's so long as all tyres are changed.
What would be the implications if I moved the Continentals to the rear and put two new D697's on the front?
thanks, Divot

You will notice that while the tyre is only 6 mm larger in radius the circumference is a whopping 37.7mm per tyre revolution larger.
Over just 1 km the larger tyre will cover an additional 15m!
Can't be good long term for your driveline.

The tyre guy is a dill, 255/60/18 is 30.0", 265/60/18 is 30.5", you won't even notice the difference, the advantage is the speedo will be closer to correct;)


265/60-18 159mm 388mm 775mm 2435mm 411 0.0%

255/60-18 153mm 382mm 763mm 2398mm 417 -1.5%

Beat me to it Rich:p
