DIY'ed tire rotation, uneven tire wear advice needed

DIY'ed tire rotation, uneven tire wear advice needed

So I finally got off my behind and rotated my tires yesterday. I was going to get it done at Costco, but first my local store doesn't have the Tesla lifting pads, and second after a member here posted that Costco damaged his car while doing it, I decided to just do it myself. Took about 35 minutes. Next time should be faster as now I know the pucks worked.

I went cheap and bought couple of hockey pucks from Dick's sporting goods and screwed on couple of rubber floor protectors I had around the house. What's cool about the Model 3 is that just lifting it by the rear lifts the whole side of the car. For added safety I put a jack stand on the front. One thing of note is prior to loosening the lug nuts, with my torque wrench set to 129 pounds I was able to get it to turn 1/8 of a turn before it clicked. The wheels have never been removed before so it was torqued from the factory. I only tested one wheel but all 5 lug nuts I was able to make 1/8 of a turn before it clicked.

My car has about 16k miles on it and is a dual motor non-P. I hardly ever get on the throttle. The passenger's side rear has visibly more wear than the driver's rear. Perhaps the driver's weight aids traction on the driver's side who knows lol. What is more concerning though is the inner edge wear on opposite corners, on the passenger's side front and driver's side rear (which are now on passenger's rear and driver's front after rotation). Tire pressure always at 42psi cold which I monitor at all times. To you guys with more knowledge on tire wear, is this an alignment issue?

These are the pucks I bought, in case you're also looking to DIY and too cheap to buy the dedicated Tesla lift pads. As always do this at your own risk. I splurged an extra dollar on the 10oz ones for $2.99 each. The $1.99 ones felt much lighter.

I would have it looked at. Inner or outer tread wear indicates a camber issue. Camber is the angle at which the tires stand.

BTW, what prompted you to rotate your tires? What I have learned from my ownership of a Tesla, and this also applies to all cars, is that one really only needs to rotate your tires if there is an indication of more tire wear one set of tires vs the other. Having a dual motor car like you have, the tire wear between the front and back should be even, negating the need for rotations.

I have a ‘14 S85 and I once went 18,000 miles without needing a rotation.

@h2ev, just a thought about lugnut torque: have you had your torque wrench re-calibrated recently? Mine keeps a pretty good setting over time, but if you accidentally drop it or if it’s been a long time, re-calibration may be needed.

what jack are u using?

Magic 8 Ball | 2019年9月8日

Passenger side rear looks worn down to were warning marks are flush with tread surface (or is it an optical illusion?).

stopnair | 2019年9月8日

also do you jack and a jack stand on the other side? was not sure what you meant by "Model 3 is that just lifting it by the rear lifts the whole side of the car".

@jordanrichard
My understanding is that the Model 3 dual motor, much of the time it's rear drive if driven normally (as in not taking off aggressively). My tire conditions bear this out. The passenger's side rear tire have visibly been more worn than the front for a while now so it's actually overdue. I didn't want to wait until it's too late to rotate them, and end up having bald tires on the front. I hope after the rotation I can get to 30k miles before having to replace them all, though I will monitor the inner edge wear on those two tires.

@SalisburySam
The torque wrench is brand new, $9.99 from Harbor Freight ;) My old one has been rusting in the garage for a while now. The Model 3 needing 129 pounds and with it being 150 pounds max, for just $10 I bought a new one just for the occasion to be safe. I did check my other car with the new one and it clicked at 76 pounds which was previously set with the old one.

@M8B
Yes it actually is quite close to the wear bar in the center. Hard to make out in the picture but perhaps 1/2 a mm away from meeting the bar. A lot more worn than the driver's side rear. No I don't weigh that much to have that much more traction on driver's side lol.

@stopnair
I only jacked one side at a time, which only needed the rear to be jacked to raise that whole side of the car, and I placed one jack stand on the front on the same side I jacked. The other side remain firmly on the ground with tire chocks. The jack is an Arcan 3.25 tons. Bought it a few years back from Costco for $99. Paid for itself many times over changing brakes on a few other cars.

when my P3D- went to Discount Tire for rotate they X crossed and said thats what to do with AWD. You could not do that lifting one side at a time???

Lonestar10_1999 | 2019年9月8日

@neilhamrin- Harbor Freight makes a cross beam product that should enable you to to lift the entire rear of the car with the front wheels on the ground. So X cross is possible for the DIYer.

when my P3D- went to Discount Tire for rotate they X crossed and said thats what to do with AWD. You could not do that lifting one side at a time??? Or lifting one end at a time. I was not clear, I mean drivers rear to passenger front.

Lonestar10_1999 | 2019年9月8日

@neilhamrin- true you can not do it with one lift but you can do it with three separate lifts.

h2ev | 2019年9月8日

I stopped doing cross rotation after another car I have became super loud after doing the rear left to front right and rear right to front left rotation. l only do straight front to rear from then on.

stopnair | 2019年9月8日

Lonestar , not sure what can be achieved by using https://www.harborfreight.com/steel-floor-jack-cross-beam-60762.html ? shouldn't the tires be rotated straight LR to LF and RR to RF? For that all you need is what mentioned in his OP.

stopnair | 2019年9月8日

@h2ev can you link the jack stand and the chokes you use on say amazon shopping site?

Lonestar10_1999 | 2019年9月8日

@stopnair- the cross beam is only required for the X cross. Personally, I didn’t buy the cross beam because the SR+ with 18” wheels doesn’t need X cross in the tire rotation.

JAD | 2019年9月8日

A bit hard to tell from photo, but it does look like a toe issue. Have it aligned before you damage the tire. As is, with proper alignment it should be ok for awhile. Just keep an eye on them.

surfpearl | 2019年9月8日

Get a tread depth gauge so you can quantify your observations and keep track of the wear.

For a peace of mind in the future I would suggest having the tires balanced at your local tire shop prior to rotating them yourself. Should be free of charge if you're their loyal customer. Yes, it requires some planning and an extra trip with tires loaded in another car, but worth it.

@stopnair, the jack stands are from Harbor Freight, 3-ton for $24. The chocks are just some cheap plastic ones I bought for like $8 for the pair. If you have a Harbor Freight store near you, I suggest the rubber ones from Harbor Freight for $8, being made from rubber less chance of it slipping.

I think the passenger's side front's inside edge is too far gone now to matter. I'll wait till I need to replace them all at once to worry about the alignment, although I will keep an eye on them. Hope by then my Costco store will have the Tesla lift pads.
