Just had a set (6) 285/75/16 Cooper STT tyres fitted to the Troopie.

One thing that I have noticed straight away, they do take a bit to get balanced. One tyre had no weights on it at all, I asked the tyre fitter if it was balanced with out any weights and he said that it was the spare and did't require balancing?????
I don't know what he was thinking but the tyre was balanced after a word to the store manager.
This is why I don't trust people who work on my Troopie and why I always check what has been done.

Next trip to try out the tyres will be a 7 day trip in the Vic High Country after the 4WD show then in June the Canning, followed by the Simpson in July. These trips should give the tyres a good work out and i will keep the forum informed on how they are wearing and the handling.

That fitter obviously has lots of faith in the STTs and reckons you will not get a flat!
We look forward to your future reports.

He must have more faith in the new tyres that I do, that is why I got 6 and kept the old BFG's

I couldn't wait that long for the Cooper STT so I gone with
Goodyear Wrangler MTR tires in 265/75/R16 size. I used
them already on couple of trips in the High Country and they
are great. A bit noisier than the standard Gradtreks but have good
wet and dry handling.

Going to Sompson in July as well, so we can probably to
the comparo of Cooper STT vs. Goodyear MTR...

It could make for a good round the fire discussion during the EO gathering in Birdsville.

Hi Wayne
Missed you last weekend up the Snowy N.P. hope you had a good trip, we certainly did.

Yeah keep us informed on the STT's it will be interesting to hear your on going reports on them, especially in the variety of conditions you drive in.

Hope they hold up better than the set of ST's I saw on the weekend on one of the trucks in our group, The owner was scathing in his comments about the quality, same as I now am about the BFG Allterains.
The BFG Muddies I now use off road seem to be quite good so far and also hear good reports on the Goodyear MTR's.

I have done 5000km with my STT's. Will see how they perform on the Big Trip to WA starting 17 April. Previously they have done very well on the French Line and Rig Road as well as Robe beaches. They balanced up very well on steel rims. They are the 265x75x16's. There are a few small cracks in between the lugs probably due to running over long stretches of gibber at under 30psi. I had a lively discussion with Coopers Sales outlet. They couldnt give me a definitive answer. Will have to wait and see.

A mate of mine has the same problem with what he said was little crackes in between the lugs. He has only done 10,000klm and has not run on low pressure. Sounds like the same problem. Might be a bad batch??

The STT's that I have only been realsed to a few vehicles for a long term trail and will not be available to the public for another few weeks, althought they have been advertising them for a short time now.

Hi Willem & Wayne
Will be interested to see what they look like after doing the Birdsville track.
My Goodyear MTR were fine after doing all the gibber roads, trip was
5700 klms with about 2000klms outback on dirt ,rock,gibber etc, however I noticed after the Mungerannie/ Lyndhurst section section the rears did show some very small chips and some 10mm cuts between the tread blocks, front tyres and side walls are fine.
The suprise to me was a 120 series Prado on grand treks which had 1 puncture, and did manage to dent the same rim 2days later after hitting a rock which may have been after a flat .

Mind you there was about 10 punctures in the group of 9 vehicles

G'day Wayne,

What size were the last set of tyres you were running? If they were 265/75s, may I ask whether there was much of a noticeable difference in gearing once you put the bigger tyres on??

Cheers mate...

I had to go with the 285/75/16, it was the only size I could get ith out a long wait.

The gearing has been affected, I am going faster at lower revs and now the speedo is reading true, 200kph on the speedo and 200kph on the GPS.

I have not had a chance to try a long run or try a hill on the express way as yet or even to go 4WDriving, that will come on the 16th April when I have to go and do the Vic High Country again.
I will let you know how they go with the long climbs and river crossings when I get back on the 24th April.
The next test will be the Canning in June and then the Simpson in July, I will be able to let you know at Birdsville on the 11th of July.
