2021 Plaid - Here we go again! SSDD and tires...

[DayTrippin]

I have the N2itive control arms already. Need to get them installed

I don't think I need all the adjustability and the associated price, not to mention Tesla is more likely to notice them when in for service. I am thinking about doing something more low-key.

So I ordered the Macsboost camber adjustment kit. It should get it where I need it and I'll use the $$$ saved toward a big brake kit that Tesla will definitely notice. ;-)

Let us know how it goes!

So here is a Question..tires have +-6k on them (4s and 21s)..you look at the inner wear and see nothing..do you feel comfortable going on a 350 mile road trip (total 700 miles)? Or in my case swap out the 21s for the 19s?

This problem is related to alignment issues. If your camber is not too negative and your toe is reasonably neutral you are fine (and lucky).

Too many of us have cars that came with too much negative camber (-2.7 and -2.9 for me) and out of range toe. The N2itive arms allow it to be fixed. They are expensive but still less than replacing tires repeatedly. And the car is much safer without the hidden danger of inner edge wear.

I would want the 19" on road trips because of the increased range plus ride quality.

How many miles are on your tires? If less than 6-7K and the wear currently look "even", then I wouldn't bat an eye at it. If you're at 10K+ and you see some uneven wear or feathering, yeah, you might want to consider starting the trip with fresh sneakers.

I changed to normal non EV tires and have air pressure at 45 psi. All issues gone.

 

[Russell]

Which normal non EV tires are you using and what size are they?

 

[DayTrippin]

I think the Macsboost camber kit is the most cost effective way to go to get you in the ballpark for camber. I don't have my alignment sheet in front of me but I think it was -1.1 and -1.3 on mine after installing the kit. One downside to the kit is there is no adjustment but will probably get many cars to a point where excessive inner tire wear isn't an issue.

I couldn't see paying for a lot of adjustability I don't really need nor having an aftermarket part that draws undue attention during warranty work. The Macsboost kit is pretty innocuous once installed.

For less than the price of 1 PS4 rear tire I am in the zone where there doesn't seem to be accelerated inner tire wear. For me that is a great ROI. Basically $200 for the Macsboost camber kit and $250 for install and alignment. Absolutely a no brainer for me.

Michelin 4S. Same size in rear and up to 275 upfront from 265.

The first 2 are to 275, the 3rd is mandatory rears gone at 9k and 4th is regular non ev tires XL Michelin 4S.

 

[URBAN LEGEND]

Anyone try my method above?

 

[DayTrippin]

Can you be more specific? Do you mean tire size, non-ev tires, tire pressure, or what exactly?

From EV tires to non EV tires. PSI at 45-47. On Michelin 4S.

 

[Dameon]

Well, 10K later on new revision MIchelin 4S "T2" tires...

Starting another Michelin warranty claim now. Dealer is saying these tires have 70% life left. More to come...

Looking harder at replacement upper links.

 

[DayTrippin]

The Macsboost shim option is a great alternative. Everyone running 21's should do something immediately or the rear camber. I am almost certain it isn't a question of if, but when, you'll have issues.

more pressure makes the problem worse, not better because it stiffens the corner that the scrub is occurring on.

no clue who started the 'use higher psi' thing because it's absolutely the wrong thing to do.

I am not mechanically inclined. Is the Macsboost shim easy to install or can I have it installed somewhere? Does it only need to be installed on rear? Thanks.

Only installed in the rear. You can easily do both sides in under an hour. Probably closer to 30-45 minutes if you are prepared. You'll spend as much time jacking the car up and getting the wheels off as putting in the shims themselves.

It's easy to farm out as well. The instructions are pretty good. A shop shouldn't charge you more than an hour of labor.
