Ive been told it's dangerous on the road to have different styles of tyre on the front and back, because when the tyres are at the grip limits it will cause over or under steering
Which AT tyres for Hilux?

I used BF Goodrich A/T on my Nissan Patrol. After 5 years (80% off-road/20% on road) they still looked as good as new and performed very well.
Expensive but.... well worth it long term
So now I have fitted a set on my latest stalking car a Shogun SWB.
Interestingly a friend told me he buys very cheap re-threads for his Shogun as with his off-road use 'the tires get destroyed very quickly, so he can't afford BF Goodrich A/T' and he has to keep buying new ones. I would say his tires don't last long because they are cheap re-threads...

Sounds like a bad idea to me. Massively different levels of grip under different conditions.
I'm with your friend, you do any serious off roading or are over rocks the tyres will get destroyed very quickly. Coming from a mechanic who enjoys fast off road bikes and being a mechanic on a forest rally team
Edit- insa turbos do last s good while in poor conditions, not great on the road however

I'm just wondering, who told you it was dangerous and did they explain why.
I know mixing things up on the same axle isn't so good but in my real life experience different styles of tyres on different axles isn't a problem

I am currently doing this and I haven't noticed any issues with handling even in the wet and driving windy back lanes with mud and moss all over the roads.

Managed to find some General Grabbers, which are being fitted today. Should be a significant improvement on the knackered bridgestones!
The answer is in the original post you quoted. Significantly different tyres will have significantly different characteristics. eg. a mud terrain will perform very differently to an AT tyre, particularly in the wet where the large tread blocks of the mud terrain lack the multiple sipes and grooves to clear water that you will find on other tyres (such as ATs). So as stated above, the limits of grip for one type may be quite different to another, leading to understeer or oversteer.
For example, mud tyres on the back and ATs on the front and cornering hard in the wet - the ATs may have enough grip to steer you around the corner with no loss of traction, but the MTs may loose grip (especially on an unloaded pickup with a light back end), resulting in significant oversteer! Under these circumstances (and under braking) it's really hard to control oversteer and tends to "snap" on you and the next you know, you're backwards into a hedge (or oncoming HGV!). Very different from a touch of oversteer in a rear wheel drive car when accelerating, which you can control by balancing power and steering (which I'm sure we've all had fun doing across a muddy field

Well put 75
The other issue is different makes and styles of tyre can be slightly different sizes because of ply rating, tread depth and construction type. This could cause permature tyre wear and could wind up the transmition depending on the 4wd system and terrain that the 4wd is used.

I'm a bit late to the party on this one apologies... Run BF Goodrich AT's on my hilux and very happy with them, they've performed well on and offroad, as for the consumption I found the hilux surprisingly poor on mpg anyway (its a 3ltr) so getting an average of 25mpg. I have had experience of the General Grabbers as well on a Range Rover and they too performed well especially at speed on road so you should find they perform and wear well. Personally I prefer the Goodrich on a truck but as I say that's really down to personal preference.
Where do you go for tyres? I used to use Micheldever all the time but I've been using Tyre Shack in Southampton of late, price is on par with Micheldever but find there's not so much queuing and the laser alignment is good with the option to pop back in a few months for a checkup. I like to get the alignment checked every 6 months to protect the initial investment of the tyres due to pot holes and offroad use.

I use Micheldever occasionally when I can't get a tyre from TRS in Andover. I haven't been near either place this week, so dropped into Tyre Sales in Abingdon who did the job.
Heading to wolf run in Warwickshire tomorrow, so i'll find out first hand how they perform in the mud as I try and get in and out of the carpark....
