Going to put something else on my 335 for the last year or so of the lease, but these tires still have four or five thousand good miles in them. Stock Bridgestone 18" RFT's. Aside from being used, they are all in really great shape. I am not an expert, but they seem to be worn evenly.
With 16k miles on them, the tread still COMPLETELY covers the blue line on the lease disc with I'd say 1/32" or so to spare, which means this could be an inexpensive option if you need to replace your tires and are nearing the end of your lease soon.
