Careful use of the throttle is advisable, but my 260bhp Caterham requires more care than the M2, I still drive it down to similar temperatures on summer tyres, too.

Thanks aerobod, interesting to hear you're running down to -5C on summer rubber. My G87 is on PZeroes from the factory, which as far as I understand aren't quite as pliable in the cold as the PS4S. That said, I've never had any issues with the RFT PZeroes on the M40i.

I think the biggest issues for me here in Scotland are going to be the combination of wet/cold (0-5C) and the appalling road surfaces (well, those plus 500nm torque ) - I've driven in 3rd world countries that have better road surfaces than the UK

I suspect I'll drive 'cautiously' as we get into November, then most likely have to bite the bullet and get full winters. One of the other UK-based G87 owners is running crossclimates on a fairly torquey EV, and he reckons anything over 300bhp is broadly undeployable in the winter here.

Might not have to go square though - have found some Japan Racing rims in the staggered OEM sizes plus Yokohama BluEarth full winters for around £2K that might fit the bill.

EDIT: interesting to see the average daytime temperature here doesn’t drop much below 7C… though that limit is obviously impacted by rain/bad roads

If you decide to get tires more suitable for inclement but not severe conditions, consider: All Weather Tires. Not as much performance sacrafice as Winters.

Great suggestion - I fit into that category and plan to use my stock rims on a set of continental extreme contact dws 02’s. Then I can buy a new forged set for the warmer months.

I assume you mean the DWS06? The 02 is a summer tyre.

Unfortunately DWS06 stock sizes (275/30/19 & 285/30/20) aren’t available in the UK

You are correct, typo (brain fart) on my end!
