My M45 is proving to have some pretty high maintainence needs and I wanna know if this is normal for this vehicle or if it's me. Car has 26k miles and I just replaced tires, brakes and turned rotors due to vibration. I've owned Nissan's for almost 30 years and also owned BMWs and drove them all the same. I've never had to do so much maint. so early in the life of a vehicle.
What's the deal?
Early wear on brakes and tires

Re: Early wear on brakes and tires (mercurio)
Since 1989 Q45 has used fast wearing PERFORMANCE items to squeeze the nth out of performance.
The early Q used Michelin tires that wore to the cords in less than 20,000 miles. The U90/U85 brake pad lasted about the same 20k, the rotors were worn to limit before 40,000 miles.
For 16 years I have trued , retrued, true, retrued the rotor to achieve oem specs at least every 10,000 miles sometimes every 6,000 miles.
Before the Q I've owned 2 300zx and a Pathfinder all suffered significant tire and brake FAST wear.
Your numbers sound great to me. I would give my Right _________ for such low frequency of maintenance.
However you are correct HEAVY Performance cars do require more of everything more frquently.
I'm sure you can redesign the M to stop longer and handle worse with other aftermarket components.

On my current 2003 M45, I get about 20k to 22k mileage on tires (high performance Goodyear Eagle F1 GS-D3). Yeah, you might be able to stretch that with "longer-lasting" tread tires, but the end result is likely to be poorer tires - wet or dry. I'd rather get performance!
My first set of brake pads lasted 35k (60% highway driving, but quite a bit of commute stop-n-go). This is outstanding compared to my first-gen Q45's, where they went about 20k miles or so per pad set.
On the M45, the rotors were lathed for this first pad change, but not replaced ... on my Q45, they seemed to last through three sets of pad changes. So, on my M45, I expect to change the rotors at the next pad change - hopefully at 70k miles.
And, yes, I am quite satisfied with this frequency for pads and brakes!
