You really have to know what type of work your primarly going to be doing.

For mud you'd want something that clears nicely, so the ET's or silverstones will get the job done.
If it's sand/road work then you'd want something less agressive like the KM2's but will still perform all round.
Rocks, probably the baja or trep.

ive been told that the couraguas dont last long

im looking more at extreme trekkers, maxxis trepadors, baja claws or the goodyear wranglers

bighorn thats all!

Mate if your worried about how long they will last, forget the ET's and similar...

I am yet to see a major flaw with the Federals anyway, know a few poeple running them on different setup Zooks, and they all do quite well .

my mates dad was running the couraguas and he didnt even get a yr out of them yet again it wasa much heavier vehicle then a zook

That statement makes no sence, mate some people do 5 years worth of driving in a year. On the other hand a set of tyres can last forever if you never drive the car. We know people that wear out a new set of mud tyres in one weekend of racing.

y would he put mud terrains on a car if its only for blacktop

talk a bout wank factor

mate if u only wanna spend $1200 go with the maxxis bighorn u should come in under that and have a very capable tyre

I run the MT-117 sports

The only time I got stopped with them (and I hit some pretty heavy mud) was when they were simply too small and the car sank to the diffs

for the money you simply cannot beat them
