Here is a listing from Discount Tire Direct.
I have owned a set of Pirelli's before and was extremely satisfied with how they held up and performed.
I had a set of OEM Continentals and thought they were crap.
I currently have a set of Yokahama's on my Liberty and the wife's R350. Actually the same exact set fits both. They ride great and performed fantastic in the nasty winter we have had.
I have dealt with Discount Tire Direct for years and have nothing but great things to say about them. I used to be an avid Tire Rack customer but as great as all the data is, their prices have drifted from being such a bargin... (remember, need to figure about $80.00 on top of their price for shipping. Discount Tire Direct ships for free).
