I got the Dunlop 21's and so far 18k km and still going to about 30k+ km I think, but yes there is more tire wear on the outer part, so maybe I will change them sooner.
I think that Michelin have a great tire, but also looking at other options, love to hear what you all have to recomend.

On paved surfaces such as concrete or asphalt - higher pressure does not necessarily equate to less traction - unless it is too high. In fact, on wet surfaces underinflation can increase the probability of hydroplaning and cause LOSS of traction. Proper inflation also maximimizes the tires' ability to stop your car/truck. What is "proper"? You need to get the entire tire footprint on the ground to get maximum contact patch based on the weight placed on an individual tire. Higher pressure does howwever, mean a bumpier (some say harsher) ride - but it also means improved cornering feedback and grip by reducing the amount of sidewall rollover. How to do it? Unless you are into making tire molds - its mostly trial and error. But you can look at the load rating of the tire and the maximum load ratings for the vehicle (front and rear usually different) and you can tell how close you need to run your tire pressures near the maximum tire pressure rating of the tire you are using - NOT what is on the door if you are not using the MFR tire. The maximum tire presssure embossed on the tire will provide the highest load rating. You can adjust down the tire pressure correspondingly if you never fully load your vehicle.

All depends on what you mean by higher pressure. If you overinflate the tire beyond the tire recommendation, yes, but with the Conti's at 45/49, there is better traction on a paved road than if you had them at 35 all around.

At very low pressures tyres 'balloon' out. On a soft surface like sand or mud this can increase the size of the contact area, and improve traction.
If you are bogged, it can be worth a try.
But don't drive on the road like that. On a hard surface, even the main tread area doesn't stay flat and give good contact with the road. On sand which will mould to the tyre surface this is fine, but on a hard road it just doesn't work. So under-inflated tyres actually have less traction on a surface that won't mould to the tyre. Also, they overheat and won't corner well at all.
