Rear Tires Worn Out at 49k

[eclectricdave]

I got my first puncture recently. On inspection it was caused by weakened resistance to punctures by the inside surface being worn to steel belt. There was nothing stuck in the tire but there was a crack. You cant see this by looking at the tire from the outside. My understanding is that there is a negative camber on the back wheels. There is plenty of tread left on the front ones so my thought is if Tesla did not have -ve camber maybe Id still be using these back ones. Im not a fast driver nor do I many launches. The tires were prob worn 10k ago. Do you think 40k is OK?

How much have you driven on low suspension setting? Some owners have worn the insides below the limit at 20,000kms due to continual low setting.

 

[eclectricdave]

I use the normal setting.

S or X? I've heard tell of people with Xs having severe camber wear problems, but it seems inconsistent as to who gets it and whether it's related to the very low setting or not. Either way, on such a heavy car 40k isn't really that bad. I'm likely to get half that mileage on an SP100D.

 

[eclectricdave]

conman Ill bet youve got the low profile tires as well. Ive got an S with 19inch wheels & wouldnt consider 21inch.

Be certain the car is not lowering automatically at higher speeds. IIRC default is any speed over 55mph the car will lower the suspension. This can be changed in the mcu options.

Mine's default setting was 100MPH when I picked it up

Yes of course I do, but it's the price I'm willing to pay. If you've ever owned any exotic sports car you just have to accept the expense, otherwise you shouldn't be driving one, but that's nothing to do with your issue if you're on 19s. Nonetheless even a 75D is a very heavy car, but camber wear shouldn't happen anywhere.

40,000 sounds pretty damn good to me. I didn't even get half of that on my first set of 19" tires. It's not really an expense I like to accept, so I started driving a bit more conservatively to get more life out of my tires.

Have your wheel alignment checked, I had it done yearly and got 60,000Km out of my first set of tyres.

@eclectricdave if you're driving on standard setting you should be getting wear similar to the photo, that inside tread has more than 3.0mm remaining after 71,000kms, that was a front but has been on the rear for the past 34,000kms. If your car is not defaulting to low setting then your inside tyre wear needs to be accessed by Tesla.

Lolz. You're talking kms. Sorry, I'm an idiot.

Well you are in the Australia/NZ section

 

[Shock-On-T]

You need to rotate your tyres every so often.

 

[conman]

By the way, there's a huge thread on negative camber on rear tyres which you might find interesting and useful.

Negative Camber in the Rear and Expensive Tires

 

[eclectricdave]

Ive read all of that & got new rears now. BTW if you approach Tesla they are prepared for it & say you need to get your tires checked evry 6 months. Im going to Pedders next week & will advise.

 

[raynewman]

Dave, 60,000 km is the go per set of tyres.

 

[eclectricdave]

but i only got 49k prob no good at 40k
