Just the thought of driving in the rain with 305 or wider R-comps on the rear and 255-ish street tires up front is scary. The understeer that you get used to in the dry can easily turn into oversteer in the wet just by adding only a little throttle.
There is a reasonably good way of estimating a tire's actual section width on wheels of various widths, either from mfr data and "measuring wheel width" or from your actual section width (330-ish) and its actual measurement at the beads (outside to outside here, to match the inside to inside at the wheel which is the way wheel width is measured).

Please let us know the wheel spec. 20x11? What offset?
Now i'm looking to buy some gauges to keep an eye on my AFR. It should be good but I've got a gaugepod that's been laying around for 4 years now so with this setup it's a good time to use it.
An AFR and boost will be the most intresting I suppose but what would I take best as third one? Any advise on that?
That was my first option for the 3rd. Some say oil pressure or temp is more important because if your AFR is good then your fuel pressure is also good, ...

Wasn't this car a 2011 at the beginning of the thread?
