[tall cool thing]

First thing I did when i bought my 2SS vert, before leaving the dealer lot, was pull off the run flats and replace with Conti. DWS06. Love these tires. Mine isnt a daily driver, but i didnt relish the idea of hydroplane/cold issues with OEM tires. Think the run flats were an easy way around the lack of a spare tire. I bought the slime setup as mentioned several posts above. I also have road side coverage with my insurance, if needed.

ya make it handle better. The guy that said that is full off bull shit.

The CR guy that said that is a tire testing engineer. I’m not saying he’s right or wrong. I do have the Magnetic Ride Control (MRC) & wonder if it must be recalibrated with different tires or does it calibrate itself? Is it the same MRC used on both the SS & RS or are they different? This is a huge concern because of where I live. I can’t drive 50 miles to a shop for repairs. To get to any decent size town is at least 100 miles in any direction. I don’t think the Michigan dingbats took the fact that many of us live in huge, open Western states into consideration.

no it does not have to be recalibrated because of different tires. run flat tires are heavy because they have thicker sidewalls to hold the car up with no air in them. This makes them less than ideal for performance. changing to a lighter tire with the same speed rating or better will make the car handle better because they will be lighter. but really its a moot point because the difference in weight isn't enough to really matter. the guy claims to be a tire test engineer. thats probably bull shit too because what he said is a lie. Sound like a car salesman when you ask about mods. They will tell you if it isnt factory it cant be done.

Looked in to a plug kit, inflator, and jack all in total was under $100 I think.

Any recent experience with the reformulated slime mentioned earlier that "washes out" and won't damage the tire or TPS? Considering swapping the OEM runflats for AS3's prior to a long road trip in July and the idea of a flat in the middle of nowhere, even with AAA and the Michelin warranty roadside assistance, isn't too appealing.

Eventually, I will get rid of my run-flats. When I do, I will get a small spare tire and a jack and keep them in the trunk.

Probably something like this, although I have not done complete research yet: https://modernspare.com/product/2016...v=f24485ae434a

^This. I've done the exact same thing (from Goodyear runflats to Michelin PS4S), nothing was "recalibrated" and handling improved, road noise all but disappeared, wet traction is so much better is isn't even in the same ballpark, all at the cost of giving up a little dry traction.

Had 4 Continental Extreme Contact DWS 06 tires installed after two years of owning my car. Night and Day difference compared to the Run Flats.

What he said is that moving from a run-flat to a non run-flat will CHANGE the handling characteristics (according to what you wrote). He didn't say that it would get WORSE.

I was just at my local Goodyear store having a tire replaced & noticed they have a new Eagle tire. They are called the Eagle Exhilarate. They appear to have great ratings so far. The treadwear number is 500, so they should last WAY longer than the F1s. Has anyone tried these?

I'd expect a 500 treadwear tire to last a long time, but have POOR performance capability (compared to the stock rubber). I haven't seen any data on the tire, that's just my assumption.

The Exhilarate beats out the DWS06 according to TR.

I concur. I’m only in a 1 LT V6 and prefer the whole driving experience and how the car handles way better on the stock runflats. The car stays flat. I can only imagine the difference in the V8. I went with the As05’s and like any non runflats there is a whole lot more tire roll which translates to body roll which translates to loss of grip and the ability to push the car where you want it when you want it there. I don’t think the GM engineers put those tires on the car just because. It was intentional for sure. But I get the problem with the runflats for anyone who deals with weather. Even what little rain we get here in So Cal I would pucker up when driving in rain once they got some wear on them. And then there’s the lifespan of them.. I only got like 15000 miles with 2 track days and spirited canyon driving. Ohh yah lol and then there’s the cost. Runflats sure ain’t cheap for how much lifespan they have.. just my 2cents. But they sure are great tires in dry warm weather!
