About 4 months ago I installed the following garage tiles with a coin pattern:

I usually only drive the Hellcat Charger every 3 or 4 weeks. The last two times I noticed steering wheel vibration at high speeds and it seemed to get worse at higher speeds. Did it both on asphalt and concrete freeways. After driving for 40 minutes it seemed a lot better. Last month I drove it again the next morning and it was fine. I repeated the same yesterday. Driving it twice for about 45 minutes. During the first drive it did it again. During the second drive I only noticed it temporarily at a certain speed. Strange thing was it would be there one minute and gone the next. But it didn’t get worse when going faster.
The car is a 2016 and still has the OEM Pirelli All Season tires with about 7500 miles on it.

Could the little coins of the tiles cause this? I will probably get the tires rebalanced to rule that out. For now I took out a few tiles where the front tires sit to see if it makes a difference.

Thanks! Are they easy to drive onto and they stay in place easily? I guess I would need to remove the tiles where I place them since they need a flat surface….

Yes^^^^ this will help, I try to drive mine about once a week or every 2 weeks. For the first couple miles I can feel flat spots but they go away quickly. I have Quickjacks that I plan to leave car on over winter to keep tires from flatspotting.

what are your tire pressures?

I'm cheap and this works:

1/2" foam insulation from HD. I went to the Loring Speed Trials last week and parked in a hotel lot for 5 days, suddenly the flat spots came back.

Truckers call this "square tires." It's from sitting a while on tires that are soft relative to the load they are facing and/or temperature, as in, "I stopped overnight in Alaska and when I started out in the morning, my tires were square for a few miles."

what are your tire pressures?

When driving yesterday I think it showed 33 psi. One might have been at 34.

Other than my recent hip replacement surgery, my car has never set long enough to do such! I enjoy driving them too much...
