Getting and Installing New Tires on your Aston Martin DB9

It doesn’t matter if your DB9 is a daily driver, track day star or a garage queen, eventually you’ll have to change your tires.  They will either wear out or get too old and become unsafe.  I use my car as a daily driver, and after about 4 years, 15,000 miles and 4 track days it was time to replace them.

Which Tires?

I did my research about my replacement tire options, and I’ve written that up in another article where I share what I learned (I suggest you check it out here).  In summary I decided to get a set of Michelin Pilot Sport 4S in the original sizes.  This article covers what I did after that decision.

Tire Options for an Aston Martin DB9

The tires on your DB9 will need replaced eventually.  You either put enough miles on them that they wear out, or if they get old enough the rubber breaks down and it becomes a safety issue.  I’ve written a bunch about tire before, including how to inspect them for wear or age (check out the article here).

When the time comes to replace them, the question usually arises “with what”.  A few pieces of good news here.  We have options and they aren’t insanely expensive.

Worn out Bridgestone

I’ve changed the tires twice on my 2005 DB9 so far.  When I purchased the car in 2013 it still had the original factory shipped Bridgestone with a 2004 date code, they were 9 years old and cracking.  I replaced them with a new set of the same Bridgestone tires.   Fast forward 15,000 miles and 4 years and I’d worn those out, and figured I’d try a set of the Michelin Pilot Sport 4S.

When I looked into the options, here is what I learned…. Continue reading “Tire Options for an Aston Martin DB9”

Screwed Again!

Well, actually it was a piece of metal that pierced my right rear tire.

Metal debris puncture

Walked into the garage this morning to see my three week old new Michelin tire flat as a pancake.  ARRGGGHHHH!  My initial thoughts were that the tire had been installed improperly by the dealer.  A quick peak around the tire and I spotted what looked like a nail stuck squarely into the tire in the center of the tread.  Crap.  If you follow this blog you may recall I got screwed in December 2016, almost exactly a year ago.

Checking the Tire Pressures on an Aston Martin DB9

Checking the Tire Pressure on an Aston Martin DB9You might be checking your DB9 tire pressures routinely or even as part of an annual service.  There are some tips I can share with you here.

I’ve used the official Aston Martin Vehicle Inspection Checklist as my guide on what we should be checking.  You can see a copy of it here.

Check out my other posts and videos relating to your tires:

Checking the Tire Pressures

You should check the tire pressures when they are cold (after the car has been sitting for several hours).  Tire temperatures go up under normal driving, and this heat increases the tire pressure (which is normal).   All the specifications are for measuring and adjusting the tires pressures when they are cold.

Tire Pressure Sensors on an Aston Martin DB9

Aston Martin DB9 Tire Pressure Sensor TPS
Yellow banded left rear TPS

The DB9 is equipped with a Tire Pressure Monitoring System (TPMS) that includes Tire Pressure Sensors (TPS) mounted to each wheel.  They are an integral part of the air valve.   You’ll notice that each of your air valves has a colored ring around it, either Red, Green, Blue or Yellow.   In your trunk / boot is a mysterious little box with LEDs.  This is the TPMS indicator panel, and if you ever get a warning indication on the dash, you’ll need to check the LED’s and see which color is lit, and that’s the tire with the issue.
