Hey guys,
I recently replaced the rear tires. I got same ones as I had before which are Nitto Invo's. What I am noticing now is that the rear feels really mushy even at slower speeds - 40+mph. It's more obvious on turns, etc. e.g. turning into highway ramps. It feels like back end of the car also has steering and fells like keeps turning (for an instant) after you make a turn... hope this makes sense.
Any idea why this is happening? I am thinking of increasing the pressure and honestly cannot think of any other idea...
Please let me know your thoughts...
Cheers!

Are Nitto's Porsche approved? most likely your new tires are just softer than the ones before, i.e., they are different production series.

Make sure they are exactly the same size, check the stagger with a tape measure just to make sure, and also that the directional arrow or "outside" marking is where it is supposed to be. Same brand front and rear?

Takes new (street) tires about 500 miles to "scrub in". This is required to wear off the mold release compounds the tire companies use. This info should be in your paperwork with your new purchase.
Check the other good advice list above, too.

Assuming you had your last tires for several years, they had become hard with age. New tires are significantly more resilient and will give you that feel. This is nothing new to anyone who has ever driven a car before with new tires.

Personally, I would never use non-N tires because Porsche weight distribution is so non-standard.

That's also why race drivers shave their tires. Read this: http://www.motortrend.com/womt/112_0...new_tires.html

New tires have mold release on them. This is basically a lubricant the prevents the tire from sticking in the tire mold while curing. This will make the tire a bit "greasy" for a few hundred miles until the tire is heated up and the surface scrubbed off a bit. In addition, the new tire has more tread which might make the tire feel a bit more "squirmy".
