Mine does the same thing, noticed it a little more last night. Was 27f out and only ran it a couple of miles. Lot of expanding contracting. Normal. I have a Raptor that does the same thing.
I like this one so much I think I will be doing it. Going to try some stickier tires and wanted a new set of wheels to go with them. Thinking Sport Cup 2 R
Bought mine (Tungsten Premium) in San Angelo, MSRP 1.5 weeks ago. When I was checking a red one is coming available in Brownwood TX in the next week or so.
