Handy to see for your self the differance between tyres, height, width and the amount your speedo will be out.

The second hand 17inchMICKEY THOMPSON ATZ are at their end now. About 50k traveled for second hand tires including oonandatta and a few trips in the Vic Alps where I still managed to get bogged or slip off tracks while traversing.
Looking a MTZ to see if I could get through this year with out a few hours of winching over and around muddy mountains tracks. I have General Grabbers AT on 18s for day to day driving and dirt road fun.
A few posts suggest 265-70-17 fit. The ATZ are 245-70-17
Tire 1 - 245/70R17 Tire 2 - 265/70R17 Size change Note Overall Diameter: 30.50 in 774.7 31.60 in 802.64 27.94
Sidewall Height: 6.75 in 171.45 7.30 in 185.42 13.97
Radius: 15.25 in 387.35 15.80 in 401.32 13.97
Circumference: 95.81 in 2433.5 99.27 in 2521.4 87.9
Revs per Mile: 681.9 658.2 23.7 less Revs per mile Look like they can get down to about $400 per tire fitted and Balanced (Guest 4wd) any thoughts appreciated before I splash out. Cheers

If it's for occasional use, also look at the Maxxis Bighorns in 265/70R17. I found them to be a better mud tyre and they're normally cheaper. Don't think they'd wear as well as the MTZ's though.

They will fit had them on my D3.
Had to deflate the spare tyre to fit it in the carrier position.
Only issue was inner guard liner rubbed on full right hand lock in reverse which I tied back with a zip tie.
No rubbing with Llams.
Another member here has the same tyres we bought them together.
If you can get a used tyre grab it for the spare.
This will be much easier to fit in the wheel well.
I now have the ATZ 4 rib in 265 x 70 x 17 on my new car.
These are a great tyre.
I stuck with the 245/70/17 as they were similar to OEM size.
Saying this many run the 265/70/17, this size is more common than the 245 & has other benefits.
I went for the BFG,around $330 each.
Don't know about the ATZ,except the have a good reputation.

						SubscriberI have 265/70/17's On BB6 Performance 17 x 8" rims. They foul slightly when turning at access height. I would go for something in between next time around. Fortunately I have these as my second set. In my opinion, visually the 265/70 do look oversize on the D4.

I have LT265/70/17 Kumho KL78 ATs on our D4, they have been great so far.
Next lot will be 245/70/17, probably BFG KM2s, they were brilliant on our D2, the 265s on the D4 drag a bit of power from the car and with all the gear we have on the car and towing a camper, fuel economy is higher then we would like.

						265/65-17 seems to be a more popular size in Oz than 245/70-17 yet about the same diameter, although some brands/patterns are still not available. They generally have a lower load rating than 245/70-17 but not by much.

						SubscriberI agree. Takes a bit of the zip out of the performance. I am also coming around to the thinking, that the more you mod a vehicle such as the D3/4, you start to change the character of the vehicle, and that is one of the reasons for choosing the D4 over the Patrol/Cruiser options.

Go the LT265/70/17 MTZ's.
They are a great tyre & work extremely well in all off road conditions.
As Admiral has said they can drain power/economy a little but i can live with that.
The only down side is they can be a little noisey, but the vehicle insulation is great & so is the stereo system
Cheers
