OP, what gear are you when this is happening?

Was assuming he must be somewhere near peak power when he was getting wheelspin. If it's in 4th gear at 55mph, ~3900rpm with stock trans/diff, then that's probably not the case...

Must be a temperature issue? Driving on a dirt road or snow, maybe? Don't see how you should be spinning 255/40-18 Pilot Super Sports (btw, those are an inch bigger in diameter than stock, intentional?) at less than 4000rpm with a 2.0 turbo that maxes 300hp.

OK, at indicated 55mph you're only making 150rwhp. Something else is going on here...
No way you should be spinning the tires in 4th gear at that speed!

To be honest I haven't been having much problems with it in the last 2 days I think maybe the roads could've been a little damp

I've never spun 4th on the stock tires with 360whp wtf are you doing dumping the clutch? I do spin third but I can feather it so it hooks.

They will lose traction unpredictably and it will feel like driving in the rain. Running a seasonal tire outside of the season it's meant for it stupid and OP has no business running them on a turbo car in winter. Jarheads...

Traction sand is the best choice cuz you can use it when you get stuck...they won't damage anything from rolling around in the trunk either.

Could your new tyres be old stock ?
If they have been sitting around in storage a couple of years traction can be way down on fresh "new" tyres

When i had my r32 gtst the tires were glued to the ground in the summer, once winter hit it was like trying to get a viper to hook up.
