Resurrecting this summary table based on comments I've been reading. Added Con #3 to the Supersize option based on what a couple of people have said.
I'm really getting sick of my MYP's harsh ride, even with the stocks underinflated, but I'm very undecided about going with the Upsize or Supersize option. I only have 3.5k miles on my stocks but I can't wait for them to wear out. Has anyone actually had seat time with both options above? I saw just one guy reported that he hated how the steering felt with the Supersize option...the rest of you with 265/40s up front, do you feel it's significantly impacted the steering sharpness?
The other factor in the back of my mind is Juniper...if it's worlds better in terms of ride, the way the new 3 is, I may eat the depreciation and trade up. Can't wait for some of you with the 40s to go test drive Juniper when it comes out and see how much better it is compared to your upgraded tires.
