AT22 Grandtreks

Towing ?
Depends on how you drive when off the tar. Driven sensibly, the Grand craps should be OK.

Put a set of Light Truck all terraine tyres on. Whilst the dirt roads are OK I would have peace of mind knowing I had good strong tyres on.

The Grandtreks on the 200 series are a much better tyre than anyone gives them credit for. One mate complained that he couldn't wear his out - he did 80,000k on the set and only had one puncture during that time while he was in the Kimberley. Another mate runs 2 sets but there days he prefers the Grandtreks to his AT's because the fuel consumption (and more importantly range) is a lot better.
Some of the roads up Innamincka way can be pretty stony and I've seen those american tyres chipped out after a run to Nappa Merrie and back. At least the Grandtreks never chip.
But you have to look after them. Like all tyres, 80% of the punctures will happen in the last 20% of the tyres life. And you must reduce pressures, keep the speed down and don't overload if you want a trouble free trip.

Hi Wak

I had them on a Prado from new. They did 40,000 kms without any problem. Most of it on gravel including Murchison, Gascoyne, GRR, part or Tanami, Wolf Crk, Arnhem Land and Wa Goldfields. All of the above towing a 2t offroad van. They are tougher than they look.

They were about 60% worn when I replaced them. Only reason to replace them was another big trip coming up and my desire so have a full tread depth for the trip. Other wise at least 20-30,000kms left in them.

No chipping, no punctures, no damage whatsoever.

Save your money and run them out. As in all matters relating to tyres how you treat them has a major impact on how they "treat you".

Enjoy your trip

Cheers John

Some good advice re tyres here. I was swinging towards replacing them as we don't like GT's much. But some happy owners with sound advice it seems. We hope that you will call in and see us at Kilcowera on your way past. You could put up a review for the Exploroz community for the trip gathering next year which will be held here! Super excited about that! Toni

The AT 22 is pretty much the standard 'factory' fitment on new Toyota's for the last few years , bit of a compromise tire , quiet on the tar and brilliant on the beach [aired down ] but fairly useless in mud even with 100% tread , longevity purely depends on where the vehicle is driven and at what tire pressures , if on tar its nothing to get 70odd thousand km out of them [ 5 wheel rotate ] whereas on the dirt and gibber its luck of the draw on any given day / strake..... mind you at full retail price they are bloody expensive , but most Tojo dealers out west have them in brand new condition for way less than 'retail' from tire change overs prior to new vehicle delivery from buyers who want a more 'aggressive' tire to begin with.

thanks for the great advice,thinking i will leave them on for the trip then ,if one grenades itself what are the availability of an 18 inch tyre in the bush?

After reading about mileages like I just want to go to a dark room and cry for an hour.
I ask myself these questions every time I read posts like this, What do I do wrong, is my driving that bad, do they save all the bad wearing tyres just for me.

I bought the vehicle on the 23-06-2013 fitted with Dunlop whatever they were, only driven between Rockhampton and Gracemere, with the exception of one trip to Mackay and return.

Below is life span of my tyre wear,
Wed, Feb - 04 - 2015
4 x 697 Dueler Bridgestone tyres and a wheel Alignment **Speedo 22100** Rocky.

Thu, May - 26 - 2016
Changed front tyres with my two brand new spares (Original Tyres) at Mt Augustus. **45687** 5mm tread left on Bridgestones.

Sat, Sep - 10 - 2016
2 new Toyo Cross Country AT 2 **Speedo 55910** Alice Springs

Fri, Apr - 07 - 2017
2 new Toyo Cross Country AT 2 + Wheel Alignment **Speedo 61797** Charleville

I am now on my third set of tyres and others still get another 20,000 more than I do from one set.
Please I am desperate and will take any advise anyone willing to share how I can get 80,000 out of any type of tyre on the market.

I have learned how to make them last a long time, but can not master how to make them go a long way.

Cheers

Do you want to take 3 spares and probably need all of them, or swap now and sell your grandtreks for $100 each? The grandtrek is a passenger rated tyre, its sidewalls are 2 ply, which is bad if you need to air down, bulging and presenting the sidewall to the rocks and sticks out that way. i asked a similar question before doing the Binns track, and decided to get coopers, im glad i did, because the coopers copped a hiding, theres chipping and pieces missing out of the sidewalls, but no punctures. Admittedly, i did the tanami and simpson, then Innamincka/coongie/hungerford coming back....
