The 255 that comes on the SL seems small. Even the base model has a bigger one (by 10mm, but still bigger).
Since the SLR is coming with a giant tire, I'm wondering how this affects performance. The extra grip would be better for launches, but the extra rotational weight would likely slow it down somewhere around the 2nd-3rd gear mark. I also wonder how it affects general handling.
Anyone have any opinions or experience?
