Default Winter Tire Installation

After a very difficult time finding winter tires for my wife's 987, Damon at The Tire Rack found 4 235/40VR-18 Michelin Pilot Alpin PA2 N1 (Porsche OE). They will be moounted on 18x8.5 Sport Edition Cup 3 Silver rims.

I plan to install them this wekend. I'll be using a floor jack (with a "hockey puck") to protect the area around the lift points. I plan to use a wheel guide too.

Any other suggestions based on previous experiences?

For safety, you may consider chocking the wheels on the opposite side of the car. Also, jacking the car by the rear lifting point will raise the entire side, allowing easy removal of both front and rear tires. I usually check the brake pads at the same time.

Hope that helps.

If you plan on doing what schnell987 proposed (which is what I would do), i'd throw a jackstand or two under just in case.

Good reminders. I'll use the jack stands and make sure the wheels are chocked. I picked up 2 bolts today to make the wheel adaptors.

I just installed the same setup from Tire Rack this wknd for winter use in New England. We got our first snow Sunday night and the tires have been great, albeit just a few miles thus far.

For reference the setting for your torque wrench when tightening bolts is 96lb-ft (in the manual). Also, those Sport Edition wheels are designed to accept the Porsche center caps if you want to and aesthetically, the rims looks very similar to OEM turbo twists.

lee88 - thanks. I received tires/rims yesterday. Will put them on this weekend. I plan to use the current center caps.

Just completed the installation of the winter tires on wife's boxster. It was a breeze

The wheel guides I made with the 15mm x 1.5mm x 5" bolts worked great. But they did cost me $2.50 ea. Now it's time for a beer

A wheel guide is basically inserted when you remove one of the lug nuts to continue supporting the wheel. Saves a lot of wear & tear on the back. Two wheel guides make it much easier. In the owner's manual it references using 2 wheel guides when changing a tire especially with PCCB.

Rather than buy a wheel guide another poster suggested using a 14mm x 1.5mm x approximately 5" bolt after cutting the bolt head off. That's what I did and it worked great. Also much less expensive than buying the wheel guides.

If you search the 997 forum for "wheel guide" you'll find a thread on "goodies for changing wheels". Below is the information Coochas supplied on the 997 forum.

I think this is a smart safe way to put a wheel on and greatly reduces the chance of crunching your calipers with those heavy wheels.
Also shown in the "soft socket" (it looks teflon like inside). Both $29 from Boothe.

Thanks! That is what I thought it was. While I never thought of having two, on the 986 (and I assume 996) the toolkit comes with one. Maybe because the 987/997 has no spare, they kept it out of the toolkit (any way to save a nickel )

That is one of the disappointments after years of owning older Porsches. My 914 had the old bolt style like the new cars, but then I converted it to studs, and well, my old 911 had studs to begin with. So much easier. Maybe I will convert the 986 to studs too!
