I have a Turbo Cayenne with 20" Technos and I'm switching from Pirelli Assymetro 275/40R20 to Michelin Latitude Tour HP 275/45R20. Cayennes chew up tires faster than anything on the market....I got 10,000 uncomfortable miles out of the Pirellis. I have a buddy who switched from Toyo 40 series to the 45 series Latitude HP's on a Cayenne S with 20's and said that the highway comfort is way better with the taller sidewall....and they still corner great.....and they're all season.

i have a pair of techarts 20" (black with silver lip) 8ish" for the fronts 11" for the rear

Here are some pictures of Toyo Proxes in 20" Champion RS97 on my CTT.

looks good...Is it lowered? thanks for the pics
