Anyone go from All Season tires to Summer performance tires?
 

Spec: 2006 4.8. I don't care about the performance factor. I'm curious how the ride changed, if any, and if summer tires wear out really fast due to being softer? I currently have Michelin pilot sport all season 3 and thinking about going to Michelin pilot sport 4S. I don't see snow ever.

You’ll see a relatively small difference in ride quality because the AS3+ is one of the roughest riding all seasons out there.

Summer tires wear out a lot faster. I’m still waiting on durability reports for the 4S, but the Pilot Super Sport also aged out really fast. 12 months and they started getting hard. 24 months and the compound was junk.

Wow that's crazy on the durability of the Super Sport. Thanks for your feedback. I only drive mine a couple thousand miles a year so not sure it's worth getting summer tires. I just like the more aggressive look of the performance summer tires.

PSS was awful. I should say that I have heard that the 4S is better, but nothing definitive. I would definitely not use that sort of tire on a garage queen, though. You might consider a less aggressive summer tire. Part of the issue is that the most aggressive summer tires have a closer relationship to R-tires than street tires. They work if you use them up on a daily, but not if they sit and age out.

(For the record, I have actually dailied on R-tires. Toyo RA-1s are the shit - if they make them in a size that works, they're awesome. Hoosier Wets are a hoot, but don't last.)

I went from OE Michelin DIAMARIS to LATITUDE TOUR HP back to MICHELIN DIAMARIS.

Feedback: LOVED the quiet ride of the Latitudes, handling is 80%-90% same, less turn in due to softer sidewalls. No longer made in 315/R20 sizes, hence my change back again.
Moving back the results are LOTS of road noise when compared to the Latitudes. Harder sidewalls mean more road feel but you gain handling. It is a trade off max-handling vs ride and comfort. Normal for big fat BMW's.

Now that Diamaris is no long made in sizes to fit a X5 4.6/4.8is, then there is only one choice:

Pilot® Sport All Season 4 Tires if you want to stay with Michelin tires.

The real challenge is keeping the tire pressure low in the rear to not have accelerated center tire wear but high enough to keep the beast planted on turns and hard runs. Everyone with different tire sizes will now chip in their own pressure /tire wear stories. The 4.6 and 4.8is rear 315/R20's are a beast sized tire and come with their own challenges. I have gotten 12K out of the rears but with proper care I should have gotten 18K. Most report 10K to 15K tire life. Fronts will go for 2X. Welcome to 5,000LBS of BMW wearing tennis shoes thinking its a Sport Activity Vehicle vs a SUV.

Those Diamaris are for sure nice but used to be. Do the All season throw you off a lot in the rainy conditions in Summer?
