Tire pressure - non-runflats ?
Just had some Conti extremecontact DW tires installed this morning. OE sizes... what cold tire pressure is everyone running on their non-runflat set ups ? I am assumming the 30 I ran on the F1's will not be ideal do to the much softer side wall ?
And by the way... as everyone on the forum preaches, the difference in ride quality and especially nosie reduction is nothing short of spectacular.
Thanks.

There are some posts (I don't have links to) that describe how the stock tire pressure is calculated based on the vehicle weight distributed to the four corners, contact patch size and maybe something about the sidewall (I'm not sure about that one). Assuming the tire dimensions are approximately the same as stock, then the cold tire pressure would be the same.
My guess on the subject is that if radically different size tires are used that have different contact patch size, the equivalent cold tire pressure would be different.

Only advantage of non runflats is price.

See my post #14. Don't know about "bump steering" but if you like to race I can tell you they don't handle any better.

Yes, amazing. Road noise is a myth. Corvette Fever did a study measuring decibel levels between runflats and non runflats and there was no significant difference. There is no significant difference in weight.

Let me step back. I think the reality is that there is a wide range of tire performance characteristics and there is now a wide range run flat tire options. And there are some run flats that will perform better than non run flats. It depends on the tire brand and the performance characteristic you are talking about.
