Well, one of my tire blew up for the third time in 30k. I would like to replace it with two 5000s and keep two good 8000s, and keep it that way for another 6 months. Would this be a bad idea? In particular, will that be worse than four 8000s on a light snow?

...since the 8000's are a maximum performance tire and the 5000's are an all-season performance tire. Handling at the limit could be wacky. Definitely suggest putting the stickier tires up front, as that will reduce understeer. Note that in the snow, the stickier tires may be the 5000's. Even though I live where it doesn't snow, I wouldn't drive on the snow in maximum performance tires though.

very noticeable. I thought I'd save $$$ by keeping on the two good performance tires (Bridgestone RE92), and only replacing the two worn tires with the SP5000 tires. Bad idea, at least for me.
The size I was dealing with was 205/55-16. In that size, the Dunlop SP5000 tires have super soft sidewalls. By comparison, the Bridgestone RE92 tires have stiff sidewalls. It was a bad mix. I was on dry pavement, but still had very odd handling issues.
A couple days later, I received, and put on, the other two Dunlop SP5000 tires. With all four SP5000s on, the handling was certainly not as good as with four RE92s, but at least it was relatively even, front to back.
I think with some tires it might be OK to mix them for a while, but with the SP5000s, it may not be such a good idea.

I won't even get into the tire pressure issues here, since two of the tire pressure ***** on this board have previously (in another thread) given their "expert" recommendations on tire pressures for the SP5000s. After that, I obtained the real info directly from Dunlop, but I wouldn't want to start another flame war here.

Good luck with the tires.
