Looking to purchase new tires for my 08 tahoe! Right now running 17" but will up grade to 20" later, just need 17" for now. I was wondering what is a good tire to get? This one guy was trying to get me to buy some Nexen roadina, or some nitto Dura Grappler, or Cooper Discover HT. haven't heard of any of these before. Could someone point me in the right direction for tires? I like the good year triple tread but really don't want to pay the 189 -219 per tire price.
