Sounds like common sense to me. If tires are cupped, etc from poor alignment, can a good long burnout round the tire again?

Some tire shop can fix them if they are not to bad. They have something that will cut the tires down.

Yes indeed it worked for me. My front tires began to show some cupping so I swapped em onto the rears and shortly they were fine.

I got the idea from my experience while working on tire uniformity machines at Akron Standard for a few years. These machines would spin a tire and, upon detecting non-uniformity, grind center or edges of the tire to improve uniformity.

I done this after having flat spots on mine from an emergency stop ( BIG DEER ) It took some time and alot of burning, but it did seem to help. Boy I really miss those tires now.

Sounds pretty extreme to me.
As stated above, some shops have tire shavers that will true a tire up, but you lose a lot of rubber in the process.

I've heard they don't like to shave tires that have been on the road, due to the little bits of rock, etc the tires pick up could dull or ruin the shaving equipment.

It wouldnt make sense to true A new tire, so I suspect they mostly true used tires. We had the tires on our Sedan Deville Balanced, rotated and trued...the next day we found a massive bulge and had to get new good years.....bummer.

Uhhhhh...dude dont you know..Burnouts fix evrything...Now go shred your tires and buy new ones

Now that's the answer I was looking for!

I think it was an SCCA article I read about shaving new tires. Road racers have it done to minimize heat. Even DOT-legal racing tires have tons of excess rubber (or they did back when I was into that).

As for truing, my '94 vette video mentions something about the plant "checking tires for uniformity." Don't know if that involves any shaving or not.

Doing a burnout will NOT fix a flat spotted tire.

I don't want to get in to the physics of it but, suffice it to say the suspension and the flex of the rubber will allow the pavement to grind the same amount of rubber off of the flat spot as the rest of the tire.

A little late with my reply; but when I worked at a Yokohama Tire manufacturing plant, they had TUO machines(Tire Uniformity Optimizer machines) as well.

Some new tires are ground by the TUO. The TUO inflates the tire to above normal pressures(I'm thinking at least 60 psi or so, maybe more) and puts a load on the tire as well and measures the uniformity. If the tire isn't within the uniformity spec., some rubber will be ground off of the tire by the TUO.

How much rubber ground off of the tire depended on how far off the tire is if it's off at all. Not all tires will have rubber ground off of them, only the ones that are off.

Different brands of tires made by the same manufacturer also have different specifications as to how much rubber is allowed to be ground off. Yokohama also makes Mohawk tires. More rubber was allowed to be removed from a Mohawk tire than a Yokohama tire and still be considered a "first" or non-blem tire.

Also, a Mohawk tire can be labled as a "blem" tire if the uniformity readings are way off and cannot be brought to within spec. without taking too much rubber off. A Yokohama tire on the other hand would never be sold as a "blem". If the tire could not be brought into specification without removing too much rubber, the tire was scrapped.

Also, not all blem tires are uniformity blems. Some are appearance blems, like when someone loads a whitewall tire in the tire curing machine upside down.

Anyway, that's they way it was when I worked at Yokohama 10 years ago. Knowing what I learned at Yokohama, I always inspect any tires I buy from any manufacturer for heavy grinds and any other possible defects as well.

I'd have to agree

Yes it can help. But only to the extent that you'll need new (round) ones sooner! The more burnouts you do, the sooner you'll have new rubber.
