handy advice cheers, as far as tyres go i think i would go for 35 simex extreme trekkers. just love the look of them

well perhaps 35s are a little bit

Shoot for 33's. They are still illegal, but with a few small upgrades, they are quite managable on a sierra.

Another thing to consider is that a sierra on 33's has the same diff clearance at the pumpkin as a hilux on 35's

i would love some one with a hilux to actually measure what the diff clearance is.

hay fats are you sure about that as my land cruser, which has a shitload bigger diff then a hilux,
has the same clearance on 33s as my sierra has on 31s.

Strop, you still haven't said what type of driving you want to do. Don't take this the wrong way but I'm thinking maybe you want it mainly to look like a big tonka truck. I ask because its a lot cheaper to mod for looks than to mod to make an offroad weapon. No point having all the boys on here recommend an expensive line of mods to maximise articulation, traction and stength if you are only planning on building it for road use and the odd fire trail. Regardless with tyres that size you'll need decent spring lift, decent body lift, big offset rims, guard hammering, cut off front bar outriggers, aftermarket transfer gears, move front diff forward, maybe bumpstop spacers etc.



I've got a pair of ln106 diffs sitting in the shed. Next time I'm there I'll try to remember to measure from the centre of the axle tube down to the bottom of the pumpkin. That should give us something to compare to the zooks.
