EV Car tax question.

When contracts are given to the lowest bidder. The result is poor quality work. That's why roads fall to bits so quickly.

Those square speed bumps were installed in the town next to where I work. They left such a large gap between them people just drove down the middle of the road and completely avoided them. A few years later they gave another contract to replace them to someone who knows what they are doing, now they work.

I don't know how true this is but talking to my bass player about the drummers Tesla low profile tyres, he said those are the tyres made for the car.
In other words he doesn't have a choice.
No doubt I'll get corrected on that and pass the info to him on Friday.

Yes, to an extent.

I suspect they are the largest wheels available for the car with the lowest profile tyres and you can't really just decide to fit tyres with twice the sidewall height on your existing wheels. So if he wants those wheels, he doesn't have a choice.

It's hard to tell from the pictures but they look low enough profile to be the 20" Model 3 Performance wheels with 35 profile tyres.

He could potentially drop to smaller wheels with larger tyre profiles (19" with 40 profile or 18" with 45 profile) but might lose the look of the top spec wheels. (I'm not sure if the Model 3 Performance, assuming that's what he has, has larger brakes or anything that specifically require the 20" wheels but i don't think so)
 
In simple terms, if he wants to stop busting his wheels as often, one option he has is to change his 20" wheels with 235/35 tyres for some 18" wheels with 235/45 tyres or 19" wheels with 235/40 tyres.

The marketing materials that came with the car probably claim the 20" wheels are the height of handling performance etc. and transform it from a humble commuter to a racing weapon but in reality he probably wouldn't notice a blind bit of difference in handling dropping to 18". He may well notice a difference in comfort and reduced frequency of busted tyres and wheels though.

Thanks for that, wrote for a 5 year old :)

What I didn't mention, and to go with one of your comments, he also received a Court letter yesterday for doing 109mph on the Motorway.
51 years old and drives like a maniac off a pub car park, you know the type.

It's unlikely to be for handling reasons, you get worse handling and performance the bigger wheels you fit. It's entirely for bling reasons.

Teslas are known for things just breaking due to them using cheese instead of metal: https://www.reuters.com/investigates/special-report/tesla-musk-steering-suspension/

bmw had had alloys that cracked easily - poor casting/design ..... steel wheels lot more impact resistant I thought -
so that's a double whammy for low profile tyres on big cast rims, form over insurance premium.

His other (much cheaper) option is to slow down a bit and not smash into quite so many pot holes at what sound like high speeds :p
 
It was quite interesting seeing that video. My alloys have plenty of spots with rubber transfer into the rim, can only come from the trye getting compacted into the wheel like that video shows.

The ironic thing is that plenty of motorsports use relatively high profile tyres compared to your 'sporty' spec family car. The notion that if you aren't running rubber bands then you are going to have the driving dynamics of a blancmange is a bit silly.

You can fit 18” wheels on a Model 3 performance but not the stock Tesla 18” because the brake callipers are too big but others are available.

There is nothing special about the tyres that come on the car other than a bit of foam inside them. You can put any tyres on it that have the correct size/speed/load ratings. They are common sizes and loads of options available for all their standard wheels from all the major brands.

A lot of people fit Porsche versions of the Michelin Pilot sports which Tesla fit because they have a better rim protector and usually cheaper but they don’t have the foam.

You can also get some ditch finders that fit if that’s your thing.

I think that's the standard as that's what's on mine. I know sometimes it's an issue as you have to go big to go over disks and calipers, but it does seem every new model of cars goes up a size (or more), I'm sure some of the Renault come with 22". The only advantage imo to lower profile tyres is they deform less when turning, however the very large con is they are more fragile (and harder to change).
 
supposedly 15% range difference at 75mph on a mod3P between 18 & 20" wheels - grist that mkwh/efficiency should be part of VED

e: article to answer johnnys 18" wheel cover impact - might give 3.4% of that 15% effficiency gain ... are there no aero covers for 20"ers
The Tesla Model 3 comes standard with aero covers that shield most of its 18-inch wheels. We wondered: Just how much of an efficiency gain do they provide?
So we went to the Chrysler Proving Grounds' five-mile oval track to test the Model 3 back to back with and without the covers.
They improved the Model 3's efficiency by more than expected, an average of 3.4 percent across speeds of 50, 70, and 90 mph and a boost in range of up to 10 miles.

The only advantage to low profile is when you have very wide slicks (so on track). But no track/racing cars use 20"+ wheels

Even then they aren't THAT low profile as when you go wider the sidewalls need to grow. It's just "low profile" in relation to the width of the tyre.

I don't mind paying my way so not against paying VED however what I am against unless its been changed lower tax rates for ICE cars, why should cars with low emissions have a cheaper tax rate than an EV?
