Well I've got them on, and some interesting thoughts so far.

They are a 33x10.5x15 with square edge so they say this reduces the handling issues..

Tbh I couldn't tell I had 33's on. Handling wise they felt like the 31's..

Now tread. They are an aggressive at, with block size and spaces.
Splices are well spaced.
Tread is 13mm

So first trip. 2330k with 300km threw the high country.. Loaded to the hilt for the rest.

I've noticed a fair few chips but the boys reckon that's the price of the high country..

But something that I have noticed is the rears have worn 1.5mm already!!!
They are soft but dam..

Will keep they update happening
