The increase in weight is not altered by the tyres. The Rolling load is what causes failures to the sub-formation layers. As I said the damage caused is on a log scale ie 2x the weight is 10x the damage. I agree that cars and lorries have been getting heavier, but over a protracted period, the jump to BEV is much quicker and roads are going to fail sooner than before. My point is that if you're going to get a BEV, get a 4x4 with good rough surface performance. You'll need it. |

V60 D4s are around 1700kg, Polestar 2 64kwh is 1940kg minimum kerb weight. 10% heavier. The other Polestar 2 models are 15% and 20% heavier. |
I’ve just returned from a long weekend in Devon, and have a few take backs from the experience of driving electric:
1. Non-Tesla charge points suck. Most are in areas you have to pay parking for, and are exceedingly expensive (ranging from 50p per kw up to 85p per kw). That’s more expensive per mile than running petrol or diesel! We went to a few hotels and all of which knew nothing about the charge points but all were chargeable and not free. 2. Tesla charge points are very good, and a lot cheaper. As I mentioned in a previous point the costs vary on time of day, but the cheapest we got was 34p per kw which is on par with my home electric day rate. There were loads of chargers (12) and not at one point were they all full. However to address what some people say about seeing loads of teslas parked around a full charging bay, you do get charged for “idle fees” so you don’t hog the charger when your finished charging. So you will naturally see a lot of teslas parked around the charge points as I moved mine when finished charging to a parking space just opposite. Also even teslas which were not charging parked close, like a fan club and similar to what I used to do with my Volvos, always park near a Volvo :) I also have to praise Darts farm just off the M5 dear Exeter. 6 minutes away from the turn off of the M5, and from the services most people visit. Darts farm has 12 chargers and the best thing there is loads to do there while you charge. This is what the charge points have to be if they are to become popular. Lovely farm shop, playground for the kids, animals to look at, dog walking area, cafes restaurants etc. Not range anxiety I had was the charge left when we arrived home as I still have the 3 pin plug and not a 7kw charger, so it takes a while to charge back up to a decent level. If I didn’t charge I would have arrived home with 7% so that’s why I topped up the battery before we left. Otherwise I would have risked it and done the hope trip without charging. |

I have the type certification for the V60 as the V5 is one of those that shows the brakes towing weight as 750kg, and it clearly says 1800kg. |

By comparison I don't know which Polestar 2 Baggy was talking about 'cos it seems badging is different here, but looking at the current model they range from about 1900kg to 2200kg. I also note that the facelift released here in May is ~60kg heavier than the pre-facelift ... probably a bigger battery? |

So it turns out the increasing weight of cars is a thing.... not just EV's but people using pickups etc. as every day drivers.
Friend of mine is a project manager for a bridge construction company - they have just won a contract with Highways England to fit motion and load monitoring sensors on motorway bridges. The concern is if there is a motorway closure, and cars are parked on bridges bumper to bumper, what is the impact if most are over 2 tons rather than 1 tons of 30 years ago.... That's not from the Daily Mail, that's happening now starting with the M56/M6 junctions and bridges. |

I have spent 37 years building motorways and dual carriageways, including being present when pavement design decisions were being made. Weight was the main parameter for depth of pavement. |
