Default Tire flat spots

My Cobra isn't getting out much, so I'm ending up with flat spots that require miles of driving to straighten out. (Goodyear Billboards)

Race Ramps Flatstoppers seem to be the only solution, but at $180+ for a set it's worth searching for other options.

Yes, I realize that driving the Cobra more often would help but are there other ways to reduce of eliminate flat spots (due to parking too long)?

Any input will be appreciated.

Put it up on stands when it won't be used for a while.

Have you tried putting your Cobra up on a lift, or jackstands?

That's how we did it back in the day.

Roll it up on thick carpet squares. It will substantially reduce the tendancy.

Or use Avons. They don't flat spot.

Adding pressure to the tires when storing will substantially help.

Oh come on. Each weekend, just roll the car two feet forward or two feet back. And I don't mean starting the engine up, just push the damn thing. That takes less than half a minute. If you can't devote three minutes a month to taking care of your car then it's time to sell it.

Just how many jack stands can you buy for the price of a set of the RaceRamp thingy? More than you need. As said above, either push it back and forth once in a while or just get the Avons and be done with it. Your Billboards will not last long, this I know...

I have four race ramps flat spot stoppers that I used several years ago to prevent flat spotting. After changing tires, I no longer need them. If you're interested, I will sell them.

FYI, they come in two widths, 10" or 14". I have the wider ones. The 10" models are recommended for tires up to 8" wide. The 14" model is for wider tires. The 14" models sell for around $250 for the set. The 10" set sells for $180.

I'm with Patrick on this one, I do the same thing exactly. If they are old I notice they flat spot more.

Agree with Patrick! I have even softer Hoosiers on my car and they flat spot terribly! To the point that it makes me want to drive the 40 instead. Seriously... the car was undriveable. Then I started moving it back and forth, just pushing, first 180, then 90. a few hours before getting it out. The difference is astronomical! Takes virtually all vibration out of the car. What little there might be rounds out much faster. Great advice!!

Had the same problem and it didn't go away after a couple of miles. If it really bothers you, invest on jackstands.

I don't have a problem with flat spotting and the tires on the NASCAR Cobra are the original from 1969. They are bias ply too. I just move it some every week or so and also have treated the tires with some treatment that seems to work well. They are the old Good Year Polyglas tires that came out on the car back then. I also saw a curved sort of pan on rollers that yoiu are supposed to be able to jack the wheel up and put it on them and they are supposed to stop flat spots but I don't know if they work or not as my way is cheaper and doesn't require extra work.

Come on, you don't think that was one of the dumbest posts in recent memory? It's like someone asking "I get a really cold draft coming in through my open window, what should I do?"

I agree. I didn't think your post was rude at all. Some people are just hyper-sensitive.

News flash, folks. If you don't know how to manage bias ply tires, you shouldn't own them. And it's not like it's friggin' rare and hard to find information. If you can post here, you can search for the answer on the internet.

Intellectual laziness and hypersensitivity abounds in this "microwave, I want it my way and I want it now society."

Put on your big boy panties and take responsibility for your own d*mned car..

Here, since the OP is incapable of looking for himself, is a Google search on "how to stop flat spots on tires"

But it doesn't show how to fix my particular flat-spots on all 4 Billboards after only 200 miles! All split and rotted while on the car in storage. Unrecoverable and gone forever. Avons now!

I agree, Patrick is rude.

And he makes at least a few large assumptions, which are:

a) rolling your car back and forth will reduce or eliminate the flat spots, since it's highly likely that your Cobra will end up at rest in the exact same spot,

2) the garage door has to be opened and closed, unless you have a Garage Mahal, but first the cars in front of the garage have to be moved in order to get a little rolling distance, the emergency brake has to be released and and reset, so we're talking about a 30-60 minute job, and

ii) if you have a polished aluminum body, then there's another 30 minutes to several hours of re-polishing the areas where you put your oily hands.
