991.2 GT3 Winter Tyres ?
Does anyone bought Michelin Pilot Alpin 4 for the 20" GT3.2 wheels? Michelin does not have the 305/30 R20 dimenions, will the 295/30 R20 XL work?
And for the front there are two dimensions:
245/35 R20 91 V N1 E
245/35 R20 95W XLE
And for the back wheels they have:
295/30 R20 101 VXL N1C
295/30 R20 101W XLC
And for the front there are two dimensions:
245/35 R20 91 V N1 E
245/35 R20 95W XLE
And for the back wheels they have:
295/30 R20 101 VXL N1C
295/30 R20 101W XLC

I had had this same issue this past November with my C4 GTS. I opted for this very set up - 2s for the front and 3s for the rear. I was a little concerned before driving but my concerns have largely faded. It’s been a wet, cold,and snowy winter so far in Toronto and I’ve had zero issues on my GTS. The AWD might be helping a bit but it can’t create true traction and grip like the tires do.

Porsche winter wheel set uses the 295 tires in the rear, but the winter wheel rims are also only 11" wide, instead of the 12" of the stock wheels.
Size: GT3 (991) with Center Lock Wheels
Front - 9" x 20" ET51 - 245/35 R20
Rear - 11" x 20" ET59 - 295/30 R20

I was advised by Pirelli not to do it - I ended up going the full OEM set. My set might be for sale still used (a local shop in NY has them) if you wanted to go that way. Only put 500 miles on them.

I just change the back tyres by removing the wheels. The initial lock i think was higher/tighter then 600NM.
The problem is on the front tyres, how do you block the wheels from spinning when trying to loosen the bolt? ( the car is lifted as Porsche advice)
