New Porsche recommended tires will cost you, say, $1000 to $1200. They ride nice have a very good grip and last...maybe up to 40,000 miles. Most Porsche drivers like it a little on the fun side...that's why we buy a Porsche. I just installed Falken 912's on mine and so far they are performing great. Now, I live in Florida and we have heat and rain which these tires are great for...not recommended for the snow country. I have 225x40x18 on the front 265x35x18 on the rear. Cost installed $604.00 at Discount Tires.
