A few weeks ago I switched out my winter wheel and tire set for summer wheels and tires and had exactly the same experience. Inner rear tread down to metal, while outer showing almost full tread. Less than 10,000 miles (admittedly soft winter compounds). I’m regularly doing 75mph on the I-70 and I-25 with a family of 5 and was absolutely horrified to imagine what a blowout with a full car at those speeds would look like.
Most of my miles are highway miles, (the vehicle drops to Low automatically) and after all the research, like many of you here I realized it was the camber issue augmented by limited toe adjustment exacerbated by the low setting at freeway speeds.
After a lot of research, and a fair bit of procrastinating I was finally convinced that there was an answer and after talking and emailing Don at N2ITIVE
https://n2itive.me, (the website is extremely helpful), I was convinced his product was the right way to go. Essentially (in layman’s terms that I understand) installing the kit gives the capability for greater range of camber and toe adjustment not present in the fixed arms from factory, allowing you to dial in recommended settings at your preferred ride height.
I ordered the parts online and within a week they’d arrived and I’ve just had them installed by Tony and the team at
https://www.evfixme.com. Because I’m on the freeways a lot, I had them align my setup based on Low setting. I went one step further and installed the lowering links to eliminate shudder and binding stress on front half shafts. Don was great and found me an installer in Colorado, but i wanted to go with the EVFIXme team based on their video.
I can’t comment yet on whether or not this solves the problem - that’ll take at least a few months of driving and checking against baseline tread wear - but theoreticslly it makes sense. I’ll say the vehicle felt better after the install and aligament (highly subjective and likely a placebo affect on my part). In addition the EVFIXme team had the Tesla Offer front trunk kit in stock and I pulled the trigger on that as well.
Sorry for the long post - but I hope this helps someone else given we have a shared problem here.
