Im having some problems finding an aggressive a/t tire for my 2005 xterra. if anybody has any suggestions that would be awesome.. pics if possible stock tire size is 265/65/r17..

The Goodyear Wrangler DuraTrac would be a great option to look into. It's not available in the 265/65-17 size but is available in size 265/70-17. Depending on your wheel dimensions, this should work with minimal to no trimming.

Like the guys at DTD said, 265/70/17 is the common upgrade. That seems to basically be the most common tire size as it's a Gm replacement size so everything is made in that size and quite a bit cheaper than 265/65 in most cases.

If I had the money i would be going with the DuraTrac's. They look to be awesome awesome A/T tires. If that's not in your budget DTD has a hell of a price on Nitto Terra Grappler's in 265/70/17. Those were my top 2 choices when I did all my research the past few weeks.
