K0260 and I both had Grapplers, they seemed just fine to me. My other tires were Bighorns and the stock Rubicon tires (BFGs?). It did take some serious momentum and wheel spin at times to plow through but they worked great until we got a section with some wet packed snow drifts that were a couple feet deep. On 35s, he seemed to have an even easier time in some cases.

The lugs seem to grab well and clean themselves out quickly. on the main road where the snow was mostly packed they handled good too. We were able to maintain control until you tried to break loose for the most part.

 

Wish I lived closer to you spinuck. Looks beautiful up north.

 

Where I live it's all boring and flat. But being semi-close the Sierras is nice.
