Flat tyres. Why one car but not the other?

[PandaOrLion]

We have two cars. Both parked in the same place and both do roughly the same journeys. If you’re doing a long drive then we always use one, but for the rest of the time we use them both the same.

Since 2021, the Kia has had 16 nails/screws etc through the tyre causing a puncture and needing something done. The Volvo has had one occasion with something damaging the tyre. Both cars have the same brand of tyres from the same garage.

why?! Any theories?

We have the same OP. Old small car seems to be fine, whereas bigger EV is getting flats all the time. Like you were switch cares depending on who is doing nursery drop off, but we do live out in the country where potholes are rife and debris from farms are everywhere. Our old Volvo used to need new tyres regularly due to big cuts etc (before the EV), so I assume it is the weight of the car causing issues.

The light would come on, we’d look at the tyre and see a nail or similar in it.
