Taycan Problem - potential catastrophic tire failure

[DerekS]

My first Taycan had Contis and I was surprised the inner tread died at 11k all the way to cord failure.

P Zeros lasted about as long but without the surprise.

I’m in dreaded Contis now and look forward to replacing them.

I have to keep coming back to the fact that if this was an alignment issue, you would see it on the treadwear. This is just basic tire wear 101 - no? We have delamination without unusual treadwear on multiple tire types. I had my alignment checked when I had this problem, and it was within or very close to spec on all measurements and the treadwear was even across all 4 tires. I do not drive my car aggressively, so there is no unusual stress due to my driving. Tire pressures are always within recommended limits (I typically run 38F, 41R on 21" summers). It's definitely a puzzle...

What is your normal ride height?

If it were excessive camber, yes you’d expect to see uneven wear across the tread. It’s not camber wear.

In every case of delamination there seems to be excessive inner shoulder wear - ie it’s not purely tyre failure without cause. The inner shoulder wear is typical of toe wear.

Under inflation is likely to exasperate the issue (and targetting 38/41 is too low - Porsche spec for turbo on 21”s is 39/37 (4-seater) or 41/41 (5-seater) - more if you’ve any payload. Note this MINIMUM cold spec - don’t ever go below it (eg if you start your drive in colder weather than the day you set the tyre pressures)…

Running lower ride height may make this worse on rear (but marginally reduce toe wear on the front).

Suggest you recheck geos with a specialist and increase target tyre pressures.

Further empirical evidence in the comments that this is more related to tyre pressures than ride height:

For me this link went to a Facebook post on a PSCB brake issue.

Looks like I'm not part of that group. Might want to copy the post text and place it here.

Once again, delamination of the r.f. tire with plenty of treadwear remaining. My original post was the r.r. tire. Of course, I'll have to buy a brand new tire. My main concern is how do I inspect for this so I don't have a catastrophic failure. I have absolutely babied this car for the last 3 years - not one inch of hard driving, and NO launches, no 'lowered settings'. I can't do anything else. This is just nuts.

Not a lot to do with hard driving or modes.

When you have the new rubber on, get toe checked and adjusted to spec on all four wheels. Then make sure your tyre pressures never fall below the minimum pressure specified.

 

[Murph7355]

Check what pressures you're running too, with an independent (of the car) gauge.

I run full load 41/44 (cold). With ambient temps 70-80F, running tire temps are usually around 44/47. I've never had that issue.

I run that now, and so far so good.

Alignment and TP have always been checked ok. And most importantly - it these were an issue, it would show up in uneven treadwear. Treadwear is exactly as you would expect with properly aligned and inflated tires. This is clearly a delamination of the tread from the sidewall.

What TP do you run (on which wheels/tyres, which body shape and which version of Taycan eg turbo)?
