Can run flats still suffer with flat spots from car storage?

[Mulsanne-Speed]

My car is currently stored for the winter on Goodyear NCT5 Run Flats.

From what I understand, the structure of a run flat tyre is significantly stronger than that of a standard tyre, therefore, are they less likely to suffer from flat spotting following circa 6 months of storage?

Many thanks in advance

Is it being stored with huge weights on the vehicle ?

Really...6 months is nothing. If there is air in the tyre, just park it up and get on with life. And ensure there is air in the tyre.

The rubber is more likely to crack from crap modern rubber, than any worries about sitting parked causing a flat spot.

Thanks for your reply stevieturbo - The kerb weight is 2,620kg, so quite heavy.

Checked tyre pressures the other day, they had dropped about 0.5 - 1 psi in 4 months, so put what was missing back in.

I thought I'd once read somewhere that run flats were reinforced, in order to enable you to keep driving on them after a puncture, so just wondered whether flat spots following storage would apply to run flats - Can't find anything online.

runflats would be stronger all round

But I have never seen any evidence of a tyre flat spotting from sitting up for 6 months, or even 6 years. Unless the tyres have sat flat. And even then, the sidewalls usually crack.

Really...it's only 6 months, I wouldn't worry. If it is such a big deal, then raise the car up on stands or buy 4 cheap wheels/tyres for it to sit on instead.

Get some covers for the wheels to protect from uv

Thanks Stevie and Chris - I think the tyres should be fine then,

The car is in a dry garage with a ceramic tiled floor. The only window being at the back (approx 60cm x 40cm), so not much in terms of UV.

I'd just read that storing for long periods without moving a car could cause flat spotting, although in this instance, I think you're probably right, as long as the pressure is OK, it probably won't be a problem.

Many thanks

Yes run-flats do flat spot. During CoVID full lock down, my car was unused for a few months, and it did create flat spots. I would go for either the full load pressure, or near the maximum permissible pressure for the tyre (as shown on sidewall). Try and push-move the car every month or so to move the contact point around. Remember to re-adjust the pressures to the correct running pressures before driving! A flat spot would normally go away after 5 to 10 miles of continuous driving.

I've had cars sit for over a year...and never done anything to the tyres.

I think some people have "issues" because they've read stuff on the internet

What about those tyre save mat things like this
