I'm finding the stock 19 inch setup on my GT2 RWD a bit too stiff. I'm looking into downsizing to an 18 inch setup. My current stock setup is 225/40/19 front and 255/35/19 rear with Michelin Pilot 4 summer tires.
It seems a straightforward option is to stick with the current widths and go to 225/45/18 front and 255/40/18 rear. I could also go square, at 225 or maybe 235/245 if they'll fit, which seems to open up many more tire choices.
Priorities:
- Increase comfort over bumps
- Decrease (or at least maintain) noise level
- Maintain safety (braking distance, avoid excessive tail happiness)
Not important:
- Absolute cornering ability. I'll never go to the track, and I don't canyon carve.
- Tread life
- Snow (SF Bay Area)
Nice to have:
- Maintain ability to stab at the throttle in a straight line without spinning wheels. I don't canyon carve but I do enjoy accelerating hard on a straight road or freeway onramp.
- Minimal impact to speedometer/odometer
I've never done wheel / tire changes before so I'd appreciate suggestions. Thanks!
