Z4M Roadster Tires

Time for new tires on the Z4M . Never do track days, mainly travel in the Z. I'm looking at Conti Extreme Contact Sports, and Michelin Pilot Super Sports. Would like to stay with stock sizes, and am concerned with wet traction and noise level. Would like some opinions.

Michelin Pilot 4S. Quiet, soft riding, with superb dry/wet handling, and a 300 wear rating. Top rated on TR.

If not wanting to spend as much as the Michelins, get the Conti Extreme. I go the Conti Extreme DWS and they are perfect for me.

Either Michelin PSS or several second choice tires - I use BFG G-force Sport Comp 2 on my Z4M and they have been very good - almost as good as the Michelins I have on another car. The Contis are also supposed to be very good.

My coupe came with the Conti's from the factory. I like them well enough and bought a second set when those wore out (at about 20k as I recall). However, I've been running the Super Sports for about a year. They are quieter, and have better grip. The change was a nice upgrade.

Extreme DWS

I had a pair of Extreme Contact DWS 06's installed on the back last week. Put 250 miles on them yesterday. They seem quiet, rode good, and have a great treadwear rating. Happy so far.

The Conti's are a good choice, particularly since you just use for daily driving. You'll like their wet weather performance also as they're actually better in the wet than the Michelins. A lot of autocrossers use the Conti's as their wet course tire which says a lot about how good they are in the wet.

My 2006 M Roadster just turned 27K miles and the Bridgestone Potenza RE760 tires are 10 years old. Will be taking a 1000 mile road trip next week and although there's little tread wear, it's prudent to replace them at their current age. Aside from breaking traction on spirited cornering (traction control disengaged), I've had no issues with these tires on dry or wet roads and may buy another set, but Bridgestone has discontinued them. Discount Tires has some still in stock, but can't tell me the manufacture date until they arrive at my local store. $764 for the set out the door with the full Discount Tire road hazard warranty, but I'm not about to mount new tires that have been languishing in a warehouse for a year or longer.

So, as an alternative I'm considering the replacement Bridgestone SO-4 Pole Position, Michelin Pilot Super Sport or Conti Extreme Contact or the all season Bridgestone RE980AS tires. Looking for recommendations on these or other candidate tires.

A CPO dealership purchase, I've owned this car for ten years, driving it for pleasure only and my local independent BMW specialist provides routine scheduled maintenance. Other than addressing minor typical BMW cosmetic issues like cloudy headlight covers, cracked windshield seals and broken cup holders, I have experienced zero issues and it looks and performs as new. Always Chevron Supreme and BMW-certified oil during scheduled servicing. The car is a keeper and will some day go to my son.

I have those Potenzas on my Miata, and about the same vintage. Very good tire too, also noticed they are discontinued but tire technology has moved on. Some good recomendations above, my fav is the Pilot 4S (which replaces the Pilot Super Sport).

Your story is similar to mine. My 06 has just over 20k miles currently. I have never taken a long road trip in mine (and likely won't). I have Conti Extreme Contact which were put on in 2010(these replaced the OEM Contis - which were much maligned) so I too will likely need tires again soon even though these have very few miles on them. It sounds like you don't drive the car on a track. I would consider the AS Bridgestones you mentioned above as they will likely give you good performance in varying weather and a better ride as well.

Thanks for the responses, folks!

So, I learned those new RE760 tires have been sitting in a warehouse for TWO YEARS!

I couldn't justify the price for the Michelin 4S set, going instead with a new set of the Bridgestone S-04 Pole Position. Discount Tires is matching the price they quoted for the RE760 tires. Since I don't do track driving, these tires should be entirely adequate for me and will likely need replacing again due to age rather than wear.

Well, I had to return to the drawing board. The two front Bridgestone S04 Pole Position tires were DOT 0517, the rears were DOT3018. Forget it. Bit the bullet and bought a set of Michelin Pilot Sport 4S DOT 4018 and 0519. With the $70 Michelin rebate I paid Discount Tires $1055 out the door including mounting and hazard protection, lifetime balance and rotation. I run 30psi front and 32psi rear.

I think you made the right move. The 4s's ain't cheap, but it is money well spent imho.

Defective valve stem causes new tire to go flat

The Michelin Pilot Sport 4S tires are a revelation. But this week my TPMS indicated a problem and sure enough, the right rear tire appeared to be low. I was en route to the BMW dealer for a courtesy wash and had them reinflate the tire, then returned to the Discount Tires shop that had installed them. When I arrived the tire had already become underinflated.

The culprit was a defective seal on the new valve stem the shop had installed when mounting the new tire. No problems since then.

However, this brand new tire now has an unsightly abrasion around the entire circumference of the tire sidewall as a result of contact with the road surface. Although I can't see it unless I remove the tire, I'n certain the other sidewall is equally damaged if not worse.

I'm concerned that the tire is now compromised as well as permanently cosmetically damaged.

I contacted Discount Tires about the issue and they said I need to talk to the manager on Monday, but I got the impression they're going to resist replacing it. Should I demand that Discount Tires replace this tire?

It sounds like you drove on it - although it could have deflated suddenly. Did you drive home with a deflating tire? If so they wouldn't be liable for replacement. If it was a sudden deflation and you pulled over as quickly as you could then they might be on the hook for a replacement either free or at reduced price.

Had the same thing happen on another of my cars - replacing the valve solved it.

Yes, I did drive on it. When the TPMS alerted,I was already in sight of the BMW dealership. There was no indication of rapid disinflation. When I departed BMW to return directly to Discount Tires, the TPMS alerted once again when I was less than a minute from the shop. When they replaced the valve stem, they acknowledged the stem they had originally installed was defective but didn't comment about the condition of the tire itself. They also dressed all four tires afterward and it was only after the dressing began to fade that I noticed the abrasion.

But my concern is, is this tire now compromised? I suspect the suspension resulted in greater abrasion on the inside sidewall than the outside.

In my post #19, I erroneously said "this week". That was wrong. I should have been clear about the exact time this occurred. DT mounted the tires on Monday 7/29. I was en route from Discount Tires to the BMW dealership immediately after the tires had been mounted by DT. Apparently they failed to verify the new stems were properly sealed.

It is "this week" that I observed the abrasion after the tire dressing has faded. I telephoned DT yesterday fifteen minutes before they closed. They're closed on Sunday. The person I talked with on the phone is the same person who sold the tires to me, was responsible for their installation, and replaced the stem when I returned. He recalled doing it, but said I need to talk to the manager about a replacement tire.

So, my belief is DT is directly responsible for this situation. If they had checked the stems as he did the stem on the tire in question when I returned, they would have replaced it before I ever departed. This stem was leaking from the moment the tire was inflated after it was mounted on the wheel.

I never saw the tire's inside sidewall. It's only after the tire dressing faded that I observed the abrasion. I believe DT should have advised me of the abrasion and offered on the spot to replace the tire, for which I purchased the DT lifetime warranty.

Doesn't hurt to give it a try - at the least they can assess whether or not the defect is structural or cosmetic.

I agree with you that DT should be responsible for the tire replacement, if anyone. The key point is that one of the new valve stems they replaced was defective, causing the problem. (If you had requested to keep the old valve stems and one of them leaked, that would be on you). However, a point of contention will remain whether the tire is damaged structurally versus merely cosmetically. It is good that you bought the lifetime warranty, and would be good to read the fine print to see what they define as damaged.

Having said that, I seem to remember one of DT's TV ad's where a tire is being thrown through a storefront window, as the voice-over comically proclaims, "If you're not happy with your tires, just return them". This case would certainly qualify.

I took off the Potenza run flats and replaced them with Goodyear F1 Asymmetrics. Man do these things stick. Also bought the spare tire kit from CarId. Takes up a bit of room in the trunk but well worth it IMHO.

After they examined the tire, DT is replacing it at their expense.
