No 17" AT tyres available for 120 series Prado?

I would think that quite a number of the members here and at lcool would be running LT 70 specs without worrying too much about the difference between S and R speed ratings. There is a school of thought that believes that you would be bloody unlucky to picked by the insurance Co for that minor difference (as compared to some way out tyres I have seen on 4WD's occasionally.) Mind you if push comes to shove then the Insurance bods have an issue they can possibly deny your claim on if the accident is at all tyre related. It's a matter of individual risk.

I changed early to D694's (which are 112S at 265/65/17) for around town and will handle the majority of 4W driving I need. These are not LT but are a good step up from the AT20's and rate highly in many reviews. Never had a problem with them and have taken them through the simpson and sturt stony desert big gibber country and the sharp shale stuff you get around the Flinders and Arkaroola. They a good tyre in the sand as well. Also have a set of silent armour in 265/70/17 that I keep for any thing that may require a more aggressive pattern. ...but probably don't need them. Will put them on full time when the 694's wear out.
A frind of mine has Pirelli scorpion AT's on his cruiser and to my memory they are not LT? They also seem to be wearing quickly and has recent problems with slow leaks in 2 tyres and punctured one on what i would describe as a fairly minor dirt road. Just bad luck? hmm ...maybe?

I fitted 245/70 -17's on our prado. I had to get new rims as well as the GX came only with 6inch rims. Have a look at my rig pic's if interested. Also fitted them on the camper using some 10mm spacers, which I turned up, as I don't like the off the shavle versions.

The 245/70-17 are 780mm dia so the speedo read much the same as the the standard tyres, which are about 776mm, depending which brand you buy. So will keep the insurance company happy. I'm not concerned with the speed rating, I'm not goind to go that fast anyway :-).

On the ply rating, from what I've read on the forum, most of the LT tyres appear to only have 2 or 3 ply sidewalls. Other may have more but I doubt if they would come in a 17inch tyre.

Speed rating for 4wd tyres (<4.5tonnes) in SA is 140kph - take no notice of the placard. Check the technical info bulletins on the Toyo tyres website for full details state by state.

Most people I know have gone to the LT265/70R17 without dramas. Up to you how technical you want to be about a diameter that is just over when the tyre is new, and is totally legal when half worn! If you were pinged for this, you'd be the first.

Yep, just looked at the specs for the two AT sets that I have:

Cooper ATR - we use for highway and moderate off-road. LT265/R17 rated at 121R.

Goodyear MTR - we use for harder off-road work (love 'em!). LT265/R17 rated at 112P.

You can really feel when you have the Goodyears on when doing 110km/h on the freeway. Just that little bit less control than the Coopers, which are much more a road based tread pattern, though there is certainly no feeling of being OUT of control!

My insurance company have been advised about both these tyres and they had no issues.

I haven't checked the specs but I will be looking at the Toyo Opats when my grand treks are gone.
I use the MTR's in 265/70x17 for off road use as well.

I also have a Prado 120 TD 2005, and I put slightly oversize Cooper LT265/70R17's on from new. Pretty happy with them so far, have done 60k on them, and plenty tread left.

Am wondering though about availability of 265/70R17's (or 17" tyres generally for that matter) at really remote locations around the country. Any feedback from members on this?

Check out Toyo Opats in LT265/70/17 121S
Mine are 10ply in 235/85/16 and have done about 100,000
on a Patrol.

Sidewalls are no stronger than similar IMHO.
