Kumho & Sumitomo together
I checked some stickies and FAQs and I think I know the answer, but I hope you don't mind a direct question to confirm my specific situation. I just bought an 03 WRX (stock) with 69K on the odo. The previous owner traded it (for a Mercedes), so I didn't get to talk directly with them. My WRX has Sumitomo HTR+ on the front, Kumho Ecsta SPT on the rear. I know I need to measure the tread depth; on first glance they look fairly similar all around. Right now the car rides smooth and straight; alignment and balance feel GREAT. Am I in trouble to leave this mixed tire combination, risking differential damage, or am I ok as long as the tread depth is almost the same all around?
I am using the car as a daily driver, enjoying the performance, and need a good all-season tire for typical midwest weather: hot humid summers, heavy summer rains, fairly cold winters with occassional snows and ice.
Thanks in advance.
