I know there are a lot of different threads on here regarding tires so I apologize in advance if this is redundant. But I just took my 2017 MS 60D in for my first annual maintenance and they did a tire gauge inspection and told me my Goodyears were at 3.5/32 with only 17K on them. Since it's less than 4/32 they aren't going to perform any tire rotation or alignment without replacing them for $900. Service Manager told me that I could shop around and that they would align my tires later if needed. I'm rather disappointed and was wondering if anyone else here is experiencing the same thing with tire wear? I don't drive overly aggressive and it's normal Los Angeles area driving - I'd expect a little more than 18k on non-racing tires. I'm thinking of riding it out for a few 1000miles more but wondering if this is advisable. The tires look fine and I'm not planning on waiting until they go bald (less than 2.5/32). And on replacement recommendations I'm eying the Michelin Pilot Sport A/S 3 or Pilot Sport A/S 3+ and was wondering what the general feedback is on these and what the difference is. The A/S 3 is about $34/tire more than the A/S 3+ It might be helpful to add your recommendations, Pros/Cons Price and Reason for your recommendation.
