Thanks a bunch Phil, nice comparison tire calculator.
Since I just discovered this after buying new Summit tires, I’ll have to wear them out first, then get skinnier tires, maybe putting in some coil spring separators to limit travel. It looks like a design flaw, having the upper A arm hardware within an inch of the tire & touching when it bounces. I did get 62K out of them before they scraped through on the upper inside front tires. Rotating more often will allow for equal “scraping” 😊 Best Regards, Mark From: (-Phil-) [mailto:p...@ingineerix.com] Sent: Friday, March 14, 2025 2:25 PM To: Mark Hanson Cc: Electric Vehicle Discussion List; Kevin Horton Subject: Re: [EVDL] Coil Spring Spacers: Tesla Y upper control arms chewing up inside tire corner Maybe consider one size narrower? Maybe the Nokians "ran wide". You can use a calculator here to make sure the OD stays the same or less: https://www.calculator.net/tire-size-calculator.html On Fri, Mar 14, 2025 at 11:06 AM Mark Hanson <markehans...@gmail.com> wrote: Thanks Phil/Kevin etc, I have the *stock* wide 255/45R19 tires on the car, about 11” wide. They seem too wide to me but that’s what the car came with. The first set made it to 50K miles - Continental’s that came with the car. The Nokian’s (much cheaper than Continentals) I’m replacing today made it to 62K (which is good) but shouldn’t be rubbing on the inside edge every time I hit a bump in the road. The clearance to the upper A arm is only about an inch from the wide tires. Looks like a design flaw – but if it takes +50K miles to eat into the tire corner, maybe not so bad. I can see tire rubber shards on the top of the A-arm where it sticks out near the tire. The car is in the local “Techne-Mech” shop today getting wheel alignment, new tires and looking at the A-arms, tie rods etc. I may have to drive to the dreaded Tesla dealer in Richmond, about 4 hours away since they have *no* stealerships in Roanoke VA. Our other EVs (Bolt & Leaf) have *local* dealerships.

Did you put different size tires on? I don't recommend spacers, the Model Y ride is already pretty poor.

I haven't seen any similar complaints on the Tesla forums that I frequent, so it is quite possible that something is different with your car. Does it have stock wheels and tires? Or, is there perhaps excessive wear of the controls arms bushings or ball joints? I have seen many complaints of issues with those.
