    Flat spot

    Hi all,
    Due to this Covid-19 I decided to leave my home town and head to our Lake property for the Lockdown.
    My question is this.
    How long can you leave a car just sitting in the garage before you "FLAT SPOT" the tyres.
    They have been 'sitting' for 4 weeks now and I am expecting them to remain stationary for at least another 8 weeks.

    Thanks in advance.

    I have left cars sitting in my garage for much longer without a 'flat spot' issue. You can also combat this by adding 10 pounds of air pressure to each tire.
    No sweat!

    I've never had flat spotting on any car stored over the winter in my garage, so up to 4-5 months shouldn't be an issue for all kinds of street compound tires I have used over the years. I do overinflate them by 10 psi, but that's about it.
