I EFFIN LOVE tires. They are one of my passions and I love studying them, watching reviews and then comparing them for myself.
All tires have strength and weakness , as mentioned above, it's situational what tire is going to be right for you. EXCEPT load rating and you should at least MATCH the manufacturer's size and speed rating. Going with tires under those values is not really a good idea.
I get it, we all don't drive our Durangos at high speeds but the suspension is tuned for a tire that has that compound. Sure you can do it, but you give up a little handling and high speed grip.
Now once you understand at least that , let's talk about climate and your actually conditions. Going with a Summer tire and a Winter tire setup is the best of both worlds IF you live somewhere where in the summer , you have high heat and in the winter you have terrible low temp and lots of snow conditions.
Negative is you have to swap back in forth seasonal with either a tire change or a owning 2 sets of wheels.
In my are for example, running All seasons is the way to go. Let's face it, summer tires are superior in every way in the warm conditions especially if you high speed handle and do pulls alot. There are ultra high performance all seasons that come really close to that performance and still can handle light snow no problem.
I'km not going to suggest anyone buy any time unless I'm asked. But I will say this, if you want another more affordable option for your Durango , look into Toyo Proxes GT 3's. They are pretty remarkable tires for the price. They are NOT Continental DWS-06 Plus competitors or even the Michelin Pilot Sport All seasons BUT they are for any other tire made under the 2 top dogs.
Run Flats in my opinion are very expensive for someone who doesn't get flat tires or live in an area which a lot of pod holes etc. I'm not saying they are not worth the asking price as they are, especially for what they can do. BUT in my opinion the extra weight of the tire , the extra cost of the tire, they are not worth it to me. I'd rather have Pilot sports or DWS-06 Plus tires over them. Lower price better performance and take the risk of a flat and just put the spare on or get a tow truck . The Run flats will get you home. So this is where the value is.
Tires are fun people and just remember when selecting them. Tires are the ONLY thing that touches the road. They are the be all end off of your safety performance and comfort level. Buy the best tires for your conditions you can afford. If your in a pinch and need tires , just get the best ones you can as again don't risk your life to cheap tires that might not be as good as people say they are.
