Anyone here know about tires?
Living in YYZ, I just got new winter tires as it's my first winter with my current car. My all seasons were 225/45/R17 and based on my mechanic's advice I went down to 195/65/R15 which have the same exact diameter. Thing is that my steering now feels much less accurate, especially at highway speed- it's a struggle to keep it going straight, the steering just seems to wander and it feels very unstable overall.
Is this due to the new tire size? The 2" drop in wheel size? The 1.2" drop in tire width? (From 8.9" down to 7.7")
Any suggestions?
