I agree! The GY LS2's are terrible! I switched to Toyo Proxes 4 Plus after my experience with them on my Audi's and I'm really pleased with their dry performance and in light to moderate snow.
All the major auto manufacturers utilize inexpensive OE tires on their cars. I know BMW wanted to save space and weight by using a RunFlat, but I'll drop $630 and bag a spare in the trunk for peace of mind!
