Hi

Going to replace the original tires with Michelin PS4S. It's a MY19 R Coupe 4 years old with 25k. Plan was

Front
255/35ZR20

Rears
295/30ZR20

Unfortunately the rears are back ordered at most places. I called Tire Rack(listed as back order ) and they said they have Porsche and BMW in the same specs for the rear that would fit on my car? They said the only difference is a subtle insignia that most people won't notice.

Do this? If I did I'd ask about sending back if they didn't fit? He was confident it wasn't an issue.

If not, thoughts about the Pilot Sport cup 2?

I was planning to have this all done at the dealer who will do alignment etc.

Thank you in advance.

 

The Cups are great tires, but more towards serious running than your original plan. The Porsche/BMW versions of the 4S are closer to your original objective. The differences are minor (like a slightly stiffer sidewall), and fit would not be an issue.

That said, it wouldn't hurt to look around a bit more. You don't say where you are, but I just put on a fresh set last month and had no problem getting them in 48 hours through either my local tire store or Costco. (I've used Costco in the past with good results, but went with the local shop because they were closer and would price match.)

Is the difference in the BMW/Porsche tires the load range? You certainly wouldn’t want a stiffer side wall, good lord the PS4S’s are stiff.

Reviews on the new PS AS 4’s seem to indicate they are a great alternative, if not better, given they don’t have seasonal restrictions.

 

Add Sam's Club. 4 Locations in Cleveland and 4 in Akron, among others. Mine has the rears in stock for pickup today.

 

Will check now , found a set at Walmart too

 

Browsing, now debating all season?

I always used Pilot sport code N(x) tires on my ex 911/ boxsters, they say have some tweaks on the side wall, etc, Probably not necessary on front mounted engine cars but doesn't hurt to get them, they just a bit more expensive.

My preference is PS4s, I also had Cup2, you feel the extra grip, wear faster and on heavy rain the traction control kicks many time when floor it/ change gear. P zero's I don't like so much but to be fair, they never failed me.

Currently I use Std PS4s (21") on summer and PS Alpin (20") on winter, I might try the Cup again.

 

This got me to consider the Conti DWS+6 and the MPS AS4 seeing as I will need new tyres in about 11 months' time (just before winter rains hit here in South Oz), so I went onto the Tire Rack site to check out their prices. I have never used all-season tyres let alone winter tyres ever, they are simply not needed here where it rarely gets down to 0C and never snows, but I thought I would check out the prices anyway.
I was shocked by how much cheaper the MPS AS4s are than my preferred replacement (same as current) MPS4S, especially the rears, $292 vs $493 for the rears and $268 vs $327 for the fronts (USD and stock 295/30 ZR20 + 255/35 ZR20).
If I ever needed or wanted all-season tyres I would go for the AS4s but I reckon I will stick with the MPS4S for now and wear the price hike.
Unless the new Conti SportContact 7 in the right sizes is available then at a good price, I have read rave reviews about it but it simply isn't available yet here in Oz in any size.

 

MPS5s are becoming available now .... https://www.ftypeforums.co.uk/viewtopic.php?f=21&t=6288

 

Yep, the MPS5 came out a while ago, covered elsewhere on this forum.
But they are the MPS5, not the MPS5S, that S on the end makes a yuge difference!
No word yet on when Michelin plan to release the MPS5S.

 

Yeah, I made it lower case to stress it was a plural ....

 

The difference in tire design between the generic and branded PS4s is de minimis particular in how handling is affected on a front engine car as already mentioned. The primary difference will manifest itself in the price as the branded production runs are more limited than those for the generics. As with any tire choice, take it easy until the tires are broken in and you get used to any potential changes in the handling characteristics.

 

Got the Michelin Pilot Sport 4S. Rears ended up being Mercedes but except for the small marking wouldn't notice a physical difference.

I can't objectively compare the new tires to the original tires, but I can say new tires sure do beat old worn-down ones. It's like an entire new driving experience. I can't believe how much more of the engine/exhaust I can hear.

I bought them from tire rack, the entire experience was painless, support amazing. Highly recommend.
