Hello everyone. I'm looking for a little insight here. My son and his partner decided the were going to try their hand a changing the brake pads on our 2015 XF 5.0 Supercharged. Upon removing the right front wheel, they were met with a somewhat unsettling sight:





These tires are about 2 years old. I took a look at the left tire, and while there appeared to be a bit of premature wear on the inside, but looked nothing like this.

I am wondering it this could be a symptom of something else wrong with this car: About 6 months ago, the auxiliary battery died. The shop that changed the battery thought it was the main battery that had died. When they removed the main battery, the car bricked itself. Ended up having to have it towed to Jaguar El Paso. $8,000 and 3 weeks later, we had the car back. The check engine light was on, and we were getting a Adaptive Dynamics error, a E-Diff error, and a TPMS error. The tech said these errors would clear (they never cleared). I am wondering if this damaged tire is indicative of a mechanical error in the suspension? Or could it be tied to the Adaptive Dynamics fault? Note: the car has drove kind of rough ever since we got it back. If anyone has any insight into this tire issue, that would be great.

Once we get the tire issue fixed, I am going to take it to my boss' house. He has scanner, and we are going to scan the car and see what comes up in regards to the E-Diff and Adaptive Dynamics issue.

Thanks!

 

Do you have a yearly roadworthiness test in New Mexico ? Reason I ask is that something like that would have been picked up much earlier by our UK "MOT Test". It looks like there is a major misalignment somewhere in the front suspension, OR wear in the inner wishbone bushes. This has the look of a toe-out problem, but one would expect both tyres to be affected if it is. I once had inner tyre wear on my first XJ6 aluminium saloon, but nowhere near as bad as this, and it was found that the front inner wishbone bushes were shot.

You haven't told us much about the car, so what miles are on it and how often are you servicing it ? The Jaguar intervals are far too long, and here, you have one of the more powerful XE models. Is it driven on a "vigorous " basis ? How are the roads in NM ? YOU could have got sime suspension damage hitting a pothole or two, but normally one would expect the wheel to to have suffered some damage as well, but you don't mention this.

 

We do not have a requirement for yearly roadworthiness testing here in New Mexico,

The other front tire did have some inside wear, but nearly as bad as the tire in the photo. I did have both tires replaced and an alignment was done. The tire shop did say the front was out of alignment, but they couldn't tell me if this damage was caused by the misalignment. They did say everything else looked fine. I do trust this tire shop, and have done A LOT of business with them. I know them, they know me, and they have always been honest and upfront with me.

The car has just surpassed 80K miles. The wheel itself did not appear to have any damage, nor was there any damage to the suspension (that I or the tire shop could see). The roads here in NM are what I would call 'average'. They aren't great, but they aren't terribly bad, either.

From here on out I will be doing regular checks on the inside of the tires. At the first sign of premature wear on the inside of any of the tires, I will take it back to the shop to recheck the alignment.

 

Have a look at this parts diagram.

The bush that fails is No 12 and often the bush is failing, but when the car is static all appears well. It's only when some force is applied using a crowbar to the front arm that the movement will be seen. This was what I had on my XJ6, a similar layout. Once the two bushes (1 per side) were replaced, all was well. OK your tyre shop is reputable, but you really need to get the car looked at by a Jaguar specialist if you can.
