Hey guys,
I just traded for some RPF1's in 17x9 +35 offset wrapped in 245/40/17 Michelin Pilot super sports. I Previously had stock wheels and tires. When I had the stock wheel/tire setup the car handled well and had lots of grip on corners (crazy I know).
I took the car to many twisty roads with the stock setup never losing traction or going sideways. I take the same route to work and back every day and there's this one corner I would take with speed to get that "on rails" feeling. After I swapped to the RPF1 with the Michelin PSS I drove around for a bit not really thinking much about the traction. Yesterday I was driving around town and there's this roundabout, got into the corner in 2nd gear and gave it some gas to see how the tires performed. As I was exiting the corner the car got sideways, good thing I had the TC and stability control on! I was surprised and blamed it on the cold temps (dash read 4 degrees celsius).
Today on the way home on my regular route i take the same corner as always just barely giving it any gas and I feel as if the rear end is "floating". It just doesn't feel like it's gripping anymore. My dash read 17 degrees celsius today too btw so this is where I started to question what's wrong with my setup.
Now I've thought about what could be causing this and I've narrowed it down to 3 possible things.
1. My alignment needs to be checked and possibly fixed now that I have much wider tires.
2. It is just the cold temps and I shouldn't be thinking too much of it.
3. The tires are far too worn out.
The car is a 2015 Subaru BRZ with stock suspension. Nothing else on the car has been changed that would affect the handling other the the rims/tires. I am running around 32-34 psi on the tires according to the gauge at the gas station so i don't think it's my tire pressures.
Has anyone else had this type of thing happen to them when switching to a wider wheel setup?
Pics of setup for reference.
