Years of sitting on a tire can ruin them. I wouldn't do a insane burnout, drive the car first I'd then deflate the tires a bit and then reinflate them to a good level, then maybe do a burnout

not sure if that'd help, I got flat spots from locking up my rear tires and spinning out... caused a dunt dunt dunt bumping, only the rear so I started WOT around corners as often (safely) and its less and less

Flat spots often (not always) will go away as the car is driven. Doesn't take any special driving procedure, just repeated flexing and proper inflation. Depends on how low the tires wer eallowed to sit, and for how long. If they were kept inflated, problems are less.

One of the things I love about the tire skates I keep the car on now (besides having more room in the garage when I'm not driving it, as I can shove it right into the corner, or drag it sideways for access) is that the rounded bottoms of the skates that the tires sit in prevent flat spots.

Long-term storage should be done with the tires off the ground, though.

easiest way to fix flat spots...... is to take the tires stick them on the back of the car do a really big skid then replace the tires... works for me every time

Are you asking about flatspots due to prolonged storage, or due to brake lockup?

Storage flatspots can be avoided by putting the car on jackstands, or minimized by inflating the tires to ~45psi before storing. If you do get flatspots, a good drive, with some freeway speeds at normal tire pressures usually will get the tire back in round.


If it's a flatspot due to lockup, you can pretty much have the tire shaved, or live with it (which is what I do with my R-comps for autocross and track days). A burnout might eventually even out the wear, but not quickly, since the lowspot will wear down too.

i also heard putting the car up on blocks you would also need to support the suspention.
