On the topic of tyres, I currently have a set of Michelin Pilot Sport 4 on my car. However, I've noticed that these are called a summer tyre with a recommended operating temperature above 7c. Seeing that I live in Christchurch where the temps do drop below that (with the potential for snow in winter), should I instead be looking at a all-season tyre?

No. High performance Summer still better at that temp. All Season is a gimmick. All Weather is the real deal. But you can't buy them here.

I drive up the ski fields in my subaru with all and any tyre and they're fine. Balding Chinese clones couldn't stop my car. Never needed chains up or down.

At high way speeds your tyre will heat up above 7C. I can 100% guarantee that. At slow speeds who cares. It will work enough and if you're dumb enough to drive like crazy then All Season, All Weather ain't gonna help either.

I've also tried snow tyres once when the week was icy. I drove over all the ice on the road in my van weeeeeeeeee. But it nearly killed me going round a tight bend in the wet the tyre just let go and I skidded 4 tyres into the on coming lane. Every other car made that corner fine. Don't. Put. On. Snow. Tyres. Unless you're in deep snow.

Insanekiwi: It’s not the cost of the car but what you do with it. I track my car so that was a superior choice over PS4. The price difference was small between the two.

If you go track days get the PS4S. If you don't, the PS4 is more all rounded.

In short, the rubber will start to harden, and as such grip will be reduced at temperatures between 7deg c and 5deg (depending on source). Frankly probiably not a big deal in non alpine New Zealand. Just need to be mindful of the reduced grip, and drive with extra caution in near freezing conditions.

UHP summer tires exposed to temperatures below -7 deg C can harden to the point where the rubber starts to cracks. Micheline says the following (with regards to the different PS4S tires):

"Tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels or using them to support, roll or drive a vehicle.
Flexing of the specialized rubber compounds used in Max Performance Summer tires during cold-weather use can result in irreversible compound cracking. Compound cracking is not a warrantable condition because it occurs as the result of improper use or storage, tires exhibiting compound cracking must be replaced"

Should note a decent chunk of the country runs summer tires year round, and I would pick that your PS4 tires would still outperform all season economy tires around freezing point. Road restrictions, chain requirements etc are based on the NZ typical fleet tire mix.

Unless you are a snow sports enthusiast I wouldn't be too concerned about running PS4 tires year round in Christchurch. Obviously be really careful around freezing point.

If you are a snow sports enthusiast, I would look at All seasons for your next set so you don't need to worry about the low temperature cracking issue.

Proper winter tires are ment to be really good in snow / ice conditions, but they are hard to come by in NZ, and there are only very small populations that live in area's cold enough to justify them anyway. (Christchurch is still a bit warm)

Thanks! This is the first car I've really paid attention to the type of tyre I put on. The car (Model 3) came with a factory set of the PS4 (with an internal acoustic foam liner) so I intended on replacing with the same as I'm getting onto 35,000km on the current set, but then I saw the "above 7c" recommendation from Michelin and started second guessing that idea.

We had those Continental tyres on our Volvo XC70 for 3 years. We replaced 2 due to wear. No punctures.

I would buy Continental tyres without any qualms - although compared to their price in Europe they are very expensive indeed.

My Mercedes came with Michelin Primacy HP's fitted which seem fine, although I have not covered much mileage. Certainly in terms of wet and dry cornering, braking and so forth they are perfectly competent.

Have you tried Tesla 3 facebook forum to see if they have any good recommendations? I am not sure how much difference it makes in terms of road noise between the insulated special Tesla versions versus what you can buy from the local tyre shop. Worth asking I reckon. I will also be picking up Model 3 on Saturday which I am very much looking forward to.

Continental do the Contisilent model with the foam liner. From what I've read about them they're not a success in that the foam comes loose and causes out of balance issues. The fix being to remove the foam and rebalance the tyres. On one US forum I belong to there's a lot of complaints about the Contisilent model and most people are ditching them and fitting other brands without the acoustic foam. I don't know if it's a problem peculiar to the Contisilent tyres or whether it's a general problem with tyres fitted with acoustic foam.

I'll be interested to know what you end up doing; at minimum $400 per PS4 on a Model 3 (maybe without the foam), it sounds like it will be an expensive job to replace even two tyres on the Model 3 (when I get it, and need to worry about replacements) - I am also thinking that maybe I need to keep a couple of spares "at home" just in case something happens since they don't come with a space saver.

Oh yeah, there's a few alternate recommendations on there, I was just over analysing the temperature recommendations 😊 All the best with your pick up! I'm sure you'll find out how easy it is to go through the tyres quickly in these cars!

Yeah, I'll be sure to post an update. I've seen some Hankook recommendations and I believe the new Performance cars come with a Hankook tyre now. At the same time, I can't say I've had any complaints with the PS4 tyres it came with - they've lasted well (even with one getting a bolt through it) and felt good to drive on. I'm not sure having a spare at home is the best idea since it doesn't help if you're out on the road. Get some of that tyre gunk stuff (make sure its good for tyres with foam liners - Tesla sells one on their online store) which should temporarily get you to a repair place assuming the damage isn't too severe. You also get roadside assistance where Tesla will bring a spare to you and take your flat away to be repaired/replaced.

I've had re003s and eagle f1s on my legacy, would say the re003s are slightly quieter and have better dry grip, the eagle f1s are slightly noisier with better wet grip. Of course this is completely unscientific and hasn't been compared back to back

I'd happily put both on the car again. I did like the look of the re003s better, but the eagle f1s have some pretty meaty tread blocks
