I replaced the tires on my LT4 today. I had ordered a set of Goodyear Eagle F1 GS-D3's in March but my tire dealer told me they were on backorder. Long story short, Goodyear kept moving out the production date and I needed to look for options as the old BF Goodrich tires on my car were worn to a dangerous point. I ended up with a set of Kumho Ecsta SPT's. Hind site being what it is, what are you thoughts about these tires? Has anyone mounted these tires on their LT4? Impressions of these tires?
