20" tire tread depth goes fast

A bit of toe is used on race/performance cars for turn in...true. BUT this is a minor aspect of handling that is totally lost on an X5- the ponderous body roll, and soft suspension makes turn in a non-issue IMO.

But you will still get this term repeated and trundled out to argue for toe.

My position is simple: try it, see if it ruins the 'excellent turn in' when YOU drive. The answer will be 'no'

The laughable point is that most drivers have no idea at all about handling, and for the life of them could not explain, never mind sense, turn in responsiveness....yet will take your comments and obsess about it- thinking "well, I don't want to give up my bmw handling" and will needlessly waste tires with this nonsense.

OK I deserve that. A bit harsh though ARD - aren't you from the M5 board?

None of these, even the MX5 is an excellent turn-in vehicle. Neither is my M5. An E30M3 though...different story.

Excellent was an incorrect term that I used. I will say this - I meant it relatively speaking. Compared to my 4.8is - the turn in is BETTER. Not excellent. I should go back and edit that...might do it later.

I agree on dialing out the toe - this is what I had to do with the 4.8is to reduce excessive tire wear. I was asking more for gathering information...not inducing a laugh at my expense.

So, let's get back to my original question - will it reduce the turn in to a point where it's noticeable? Most likely not, but seeing as how I was annoyed at the 15kmi tire wear on the 4.8is, I will be especially annoyed at that same tire wear on expensive run flats.

Respectfully,

Mitchell

OK, so I did tee off on you a bit.... The whole 'we set toe to help turn in' was an issue over on M5board too... drivers that would ever see a track or know what turn in is, were wasting money and tires for something that isn't really much of an issue for them.

I guess I should have said "try it and see how it works for you". I'll submit that after getting 30-35k miles on your tires, you'll like the turn in just fine.

I have the same problem as well. The middle of the rears wear out amd am in my 4th set of tires.
I run Michelin tour lats.
Would like to hear from others who have the same tire (stock size 20" sport) What PSI do do run if you have even tire wear?
