I guess a little more info on what type of driving you plan on doing would help with giving suggestions. The Terra Graps are a great tire that I have used on my XK to accomplish a more agressive look for the street. If you plan on tackling mud the Terras will do well but the Trail Graps are better. They both are awesome tires but the Trail Graps are $100.00 more per tire! Trails run $275.00 and Terras around $170.00 I am upgrading to a a more aggressive tread similar to the Trail Graps but for a similar cost to the Terras. Wild Country MTX 275/70/17. Hope this helps.
