If a car comes out of storage with a permanent flat spot, the real question isn't whether it's noticeable — it's what it actually costs to fix, and whether "fix" is even the right word.
There's no repairing a permanent flat spot
A temporary flat spot resolves itself with a short drive as the compound warms up. A permanent one doesn't — the internal structure of the tyre has taken a lasting set, and no amount of driving, balancing, or realignment corrects it. The only real fix is replacement. That distinction matters because it changes the conversation from "minor annoyance" to "unplanned expense," and for performance and collector vehicles on specialist tyres, that expense is rarely small. (For the full explanation of why permanent flat spots happen, see our complete guide to preventing tyre flat spots.)
The direct cost is only part of it
Replacing one flat-spotted tyre on a performance or exotic vehicle usually isn't a like-for-like, walk-in purchase — many of these sizes and compounds are special order, with lead times that can stretch to weeks depending on the model and market. If only one or two tyres are affected, there's a further complication: mismatched tread wear and compound age across an axle can affect handling balance, which sometimes means replacing more tyres than were actually damaged just to keep the set matched. What started as a storage oversight can end up as a full-set replacement.
The cost that doesn't show up on an invoice
For collector cars specifically, there's a cost beyond the tyres themselves. Buyers and appraisers treat tyre condition as a signal, not just a line item — a flat-spotted tyre on a car being sold or appraised reads as a car that wasn't stored carefully, and that impression tends to generalise. If the tyres weren't looked after, what else wasn't? That's rarely a fair conclusion about the rest of the car, but it's a common one, and it can affect negotiating position at exactly the moment it matters most.
Weighing it against the alternative
A set of tyre cushions is a one-time purchase that protects every storage cycle going forward, not just the next one. Compare that to the cost of replacing even a single set of performance or exotic tyres — often several times the price of the cushions themselves — and the economics are straightforward. ALTairEGO's tyre cushion range is built specifically around this: Super, Magna, and Leader cover vehicles up to 2,000kg, 2,750kg, and 4,000kg respectively, so the upfront cost is matched to the vehicle rather than a one-size-fits-all guess.
The takeaway
Flat-spotting isn't just a driving inconvenience — for a stored performance or collector car, it's a real financial exposure, from the tyres themselves to the lead time on replacements to the way it can colour a buyer's view of the whole vehicle. Measured against that, the cost of proper tyre protection during storage isn't really a cost at all — it's the cheaper side of the comparison.
