I went with new tires after one of my GoodYear RT/S melted on the hwy.
I picked Pirelli Scorpion STR-A tires after reading a few good reviews about them. I liked their specs as they were all-terrain, mud and snow rated, with a T speed rating and 60,000 mile treadwear.
Plus they were about the same price as another set of GoodYear RT/S.
I drive 99.999% on road, with the occasional, brief (read no other choice) off pavement run. I don't do any true off-roading.
The tire guy wanted to sell me another set of knobby aggressive tread mud stomper type tires. I had the tire guy special order the Pirelli STR-A for me, and when they arrived he remarked that it looked like a very good road tire, then asked if I ever did any off road driving in my SUV. I answered, not many people in NYC do. I need a durable, multi-tasking tire that can handle ABUSE and give me a comfortable ride when it isn't taking a pounding. These have lived up well, and the traction is top notch.
There was an immediate improvement in comfort, handling, and noise. Shortly thereafter, I installed Edelbrock Performer IAS Shocks, and some time thereafter the EE Rear Sway Bar. All made their own improvement.
The Trac just gets better with age.
