In the next 1000 miles I will be taking my '03 F4i into the shop to have it's 8,000 mile checkup performed and I will likely be in need of new tires. I am curious what the majority do when tire replacement time comes. Do you walk into the shop and pick from their stock selection and say, "Put those on my bike."? Do you purchase tires elsewhere, before hand, carry them in and say, "Put these on my bike?" Purchase other tires not currently at the shop, through the shop?
