    Tyre Confusion again!!!!!

    Hi all, i promise i will stop posting about tyres soon. With such a big investment ( i need 6) i want to get it right. I was looking at replacing my 235/70R16 Cooper ATRs which have done about 70,000kms with another ATR.
    I have been advised to go with different things by different shops of course.

    Main contenders seem to be :

    Cooper -not too keen to use these again in ATR or ST.

    Pirelli Scorpion in 245/70 -not sure about the off road ability of these particularly if it gets muddy

    Pro Comp ATR in 245/75 - seem great with 80,000km warrantly and 10 ply etc.

    Lots of other great tyres do not come in the right size for me.(BFG/Dick Cepek etc.)

    I have decided not to do a lift yet as funds will not allow, but am keen to go with something a little bigger/taller. So a 245/70 or 75 seems to be the go.

    Any advice please ? vehicle is a 2003 D2a auto, ARB bar.

    Any reports on the Pro Comps would be great.

    Not too fussed about more road noise in favour of off-road security

    Thanks all

    Paul

    Mate - I have run the stockers, then Pirelli Scorpion AT (the one that won tyre of the year a while back in 4wd Australian Monthly) and now (for the last 40k or so) Maxxis Bravo 751 AT - would not go back to any of the others. 245/75/16 in an LT. Magic on road for towing with 3 ply side wall in very high load rating. Magic in wet and dry. Very good in sand off road when let right down. Seem good (but never as good as a muddy obviously) uphill off road and no chipping. Excellent wear so far to. Predictable and good handling and good braking. Noise is excellent.

    Cheers

    ps. I have a mate with a set of General Grabber AT2's in 265/70/16 that are a very nice tyre too. More aggressive looking than mire, but looks dont tell the whole story.

    The other issue/concern/worry I have is how readily available this size is if i get stuck somewhere remote (ish)?
    Is the 245/75 R16 a common size?

    Thanks again

    I am running the Pirelli Scorpion ATR in 245/70 16 on my RRC. They have been quite good in mud and are excellent on the blacktop (I do lots of highway driving between Adelaide and Horsham).

    245/75/16 is a fairly common tyre size, i had a a set of 245/75/16 maxxis bighorns in my old d2 and they were fantastic, apart from the road noise.

    I had a feeling that 245/75/16 was the standard size on the long running outgoing Prado GXL thingy - last shape. I may be wrong, but it is a common size. You will get less punctures with a 75 in an LT.

    Cheers

    Less puncture in a 245/75/16?

    Why? Or did you mean because its a LT?

    Punctures are often luck or bad luck and tyre pressure.

    I also have the Coopers ATR at the moment.
    Trick is to have right pressures and right speed for various surfaces.
    They tend to chip because of too much pressure and excessive speed.
    Also, make sure its the LT version that is compared to other tyres.

    My best mate has swapped his Coopers ATR's just recently to BFG KM2's ATR's and I must agree, they handle and look the goods, even on a Patrool.

    I am sure he has 235 or 245 75's in 16 inch. So they are available just maybe not at the moment.

    I change tyres when down to 70% wear so in next 12 months I will get the KM2's also I think.

    Good luck with tyre choice, remember though that not all tyres will suit all situations and its important to be real when evaluating time hoping to spend off-road to time actually spend off-road.

    Mainly cause its an LT, but every time you increase sidewall height you increase your margin for error and damage when aired down.

    Its the opposite actually.

    When aired down, you must reduce speed.
    When you watch how the tyre performs at slow speed, it actually deforms when moving over rocks, sticks and other objects and hence much less susceptable to any cuts and punctures.

    I stayed in botswana(Africa) and we lived in Landys some time, air pressure was 19-25psi most of the time when we hit rocky rough terrain.
    They only used skinny tyres as that is what most professionals use and not one puncture.
    My old mate a retired deer hunter tells same and research shows that high side walls have more flex and more suited to off road of course and not performance but that is what was discussed I guess.

    Low profile tyres are not suited for the bush.
    can be very expensive too trying to get a 60 series or lower tyre in the outback.

    BG - I might not have been as clear as I could be. If you HAVE to air down - for example the beach the higher profile tyre achieves the long footprint sooner than a lower profile tyre on the same rim and gives you thus more tyre between the sand and the rim compared to that lower profile tyre - meaning less chance of a pinch puncture. In any event always having more tyre between the outside world and the rim is a good thing off road. I agree that on rocky off road and even mud tall skinny tyres are the way to go and Rover have always got that right (at least until D2's in upper models and D3,D4).



    Cheers
