245/70/17 AT3 vs 245/75/16 S/T Maxx

[Steve223]

Hi Together,

Thinking about getting 6 x King Steel Rims with Cooper S/T Maxx 245/75/16 as second set to use if I mainly travel back country/off road.

Would assume it's advantageous to have more "rubber" on the 16' wheels then my current 17" inch?

Are there any negatives going down to 16 inch wheels, especially off road?

I think the 16" tires are also quite a bit cheaper then the 17" which would be a nice bonus.

Also tempted with the 265/75/16 just not sure with the rubbing.

Cheers

Steve

I didn't think that 16" fit on a D3.

I didn't think that 16" fit on a D3.

Hm according to Tyrepower the King Steel do fit. I asked them twice as I also had in the back of my mind that they don't.

Gordon from OL also mentioned the would fit!

Does someone run 16" on a D3??

I didn't think that 16" fit on a D3.

There was a thread on this on the disco3 UK site and i believe Graeme is correct.Looking at my 17's,there is no clearence for 16's.

Unless you want to hit the callipers with a grinder:angel:

[TerryO]

It's really hard to imagine that any 16's will fit on a D3 even specially designed ones but having said that up until Gordon had made up specially 18's for 3.0 litre D4's everyone thought that was impossible as well.

cheers,
Terry

[Steve223]

yes actually have to correct myself the King wheels where quoted as 17" but when I mentioned this to Gordon he said why don't you get 16" and apparently he can source them. King is closed so waiting for Dural Tyre Power to get back to me in the new year and/or for Gordon to return.

[gghaggis]

Think it will be a disappointing wait. Doubt you could make a 16" with enough clearance that would meet the load rating.

Be nice to be wrong though ......

Cheers,

Gordon

[Steve223]

Ok according to Gordon you can have 16" wheels if you don't have the Brembo breaks (which I don't have) so will order the wheels from him in the new year, hope he is right there....

[IvanR]

Just measured some D1 steel rims (16") and the largest size inside the rim after allowing for minnium clearance for the brake caliper is 15". The radius measurement of the brake caliper on my D3 is 7 3/4 " +, therefore 15 1/2"+ Diameter. Suggests that 16" rims will be a very tight fit.

ps I run 245/70/17 on my D3

That was the advice for fitting 17" rims - are you sure he's not confusing the 2?

[Graeme]

Do 17s fit over D3 V8 front brakes?

[sniegy]

No.

I guess I will see when Gordon is back and purchase trough OL so if its not working he can take them back. I assume it would not wreck anything trying?

Never heard of anyone getting 16" wheels to fit D3.. Maybe wrong though!

As I see it, the main reason for fitting 17" rather than 18" on a D3/4 is (was?) the availability of LT tyres rather than a little more sidewall height. 16" may have more brand/pattern options but I thought there were enough 17" options to stay with 17" and not have unusual and perhaps unpopular size rims if wanting to sell them later, assuming they do fit. Furthermore I suspect that 245/70-17 or 265/65-17 is more likely to be available in an emergency than the 16" equivalent sizes, being standard sizes on popular late model vehicles.

[Steve223]

thanks Grame, resell value does not really bother me as I intend to keep 17 LR wheels with my AT3 for touring and also intend to keep the car for next 5-10 years. I thought there was more availability in 16" so assumed they would be easier to come by? Gordon mentioned the price of 16" tyres would be quite a bit less then 17" with 6 wheels I thought together with advantage of more rubber 16" sounded compelling.

if that does not work would be also ok with 17 wheels.

would also like the 265 but don't want to run in to trouble with suspension though I understood if I have LLAMS I should be ok? how much would the speedo change with bigger tyres ?

someone could write a book about the tyre wheel issues for the Disco.

[Graeme]

265/65-17 has basically the same nominal diameter as 245/70-17 (30.6" / 30.5") although variations occur between brands and patterns. My Yoko 245/70-17 are listed by Tyrerack as 30.8" and whilst they rub the rear inner guards a little when right down, no damage was done on a 20km drive home to put the tyre compressor to work.

Some have :)

Plenty of people on this forum run 265/70R17 sizes, in MT patterns. If you play a lot off-road, this is the best option for the least work - there will be no real advantage to using 16's. Some small mods to the rear wheel-well liner may be required, but with a set of Mickey Thompson MTZ 265/70R17's on and either LLAMS or rods, your D3 is only limited by your desire to keep the panels straight, once you know how to drive to the technology.

Gordon

the above posts are about different sizes.

265/70/17 are approx 31.8 inches,while 265/65/17 are approx 30.8.

OEM size is around 30.7 inches.

Confusing,all this tyre stuff...............

Yes, I realise they're different sizes. The point is that if you want a second set of tyres to play off-road, you may as well get the largest that fit and are legal (in most states). Hence the reference to 265/70R17. In that instance, getting a 31.8" tyre in a 16" rim size provides no real benefit.

Thanks Gordon, one more questions what's the difference between your 17" rims and say the King Steel 17" rims ( beside the higher price ;-) )

[scarry]

Steve223,one question as well,bit off topic:o

Where did you get the rock sliders from,what brand are they?

Did you fit them yourself?

Thanks

? The 17" rims I had were LR rims. I sell 18" rims.

Bought them from Disco3QLD here on the forum, had Peter fitting them
but should be not much issue fitting them yourself ideally with a jack which holds them in place.

the holes in sliders did not match 100% so I have one screw left out on each site

Hi Gordon,

what mods would I need to make to the rear wheel liner?
Is it easy to do myself?


Thanks

Steve

[gghaggis]

The mods for the tyres is fairly simple. There will be rubbing when at full articulation (compression) in the rear wheel-well, on the front part of the plastic liner. If you remove this liner, you'll see a metal seam that sticks out approx 2cm or so. Bend this back so it doesn't protrude so much and replace the liner (note if you have rear AC, you may have to re-route the AC lines, which is a harder job). The wheel will still rub on the plastic when fully compressed, but the metal seam will no longer contact the tyre.

Cheers,

Gordon
