I've run three different Z-rated tires in 205/55R16 on the E0 stock rims. OEM Goodyear Eagle GS-C (can't find in my size anymore), Firestone Firehawk SZ50 (nice tire but they get stiff on cold mornings), and Bridgestone Potenza RE730 (only had for 3000 mi before engine went, but happy with performance and price so far).
Get those crappy H-rated's off there. Yuck. The previous owner should be flogged. Obviously didn't know what they had in the SVT or were too cheap to care.
