Winter storage - Tire flatspotting
 

Is this something to worry about? I'll be storing the car over Toronto's winter for about 4 months.

Should I be worried about my new tires flat spotting? The tire pressure is at 35 right now, should I bump it up to 40ish?

Last year was my first summer with my Z and I was on stock 18" and I didn't really care about flat spotting cause I was going after market.

I honestly didn't feel any difference after the winter.

I can put on my stock wheels but thats really a last resort, I don't want to haul my wheels to the shop again.

I am by far no expert but have stored my Z over the winter for 4-5 months the last two years. I have had zero flat spot issues.

I don't use anything and don't have any issues. If you're really concerned about it, pick up some flatstoppers. Flatstoppers | Car Ramps | Long Term Vehicle Storage

Your tires will flat spot some. The first time you take it out and get the tires up to temp. The flat spot will go away. Don't worry about it.

i am from winnipeg we have 6 month of winter and no flat spots ever!

I got winter wheels nd tires and now have the original wheels and tire , each leaning against garage wall in upright position. The question is whether I should store it in horizontal fashion, lay it flat and stack the tires on top of each or stand them upright as I have?

Flat spotting was a problem for older cars and classic cars. Drive your car for a mile or less and they will go away, tire materials and construction has come along way and this is not an issue.

yah, tires do flat spot... while parked on a concrete floor psi to 40-45 at least, and roll the car without starting every 5-6wks if you can.

i use 42-43psi (at ambient) and place on these platforms called flatstoppers. even so, i turn the wheels by hand every 8wks by 1/3 turn.

yah, dats wat people told me until some dunlops summers i had permanently flatspotted.. so never again am i taking that chance on tires that are 300+ each.

OP if you're that concerned.... go to your local home care store, i.e. Home depot or Lowes.... pick u some 2" hard foam insulation and drive on them.
The 2" may seem high, however they will climb it and the rears will chew up the first 6" and make a small ramp;) good for lowered cars to place the jack under too:tup:
That's what did and still do. I repeated the rear shredding twice so I can use a pair in the front too. much easier to climb than wood. You tire catches 100%. will never spit it out!!
(cheap tip)

Or if you want to get real crazy put the car up on blocks, saves the suspension too!

I laid mine flat, with no weight on them I don't think I would matter, but I have mine on a cart so I can roll them out of the way if I need.

Bump the tires up to about 40, if you can go move it every 2 weeks or so. If not put additive in the fuel tank and disconnect the battery. I do this as a business for military personnel and this is what I do for all the vehicles in my facility
