FINALLY! The spacers arrived this morning and I got the tires mounted up this afternoon... I've put about 45 miles on them including stop'n'go lights and highway driving and here are my impressions so far:
--Big "harsh" bumps (highway speed) are much softer
--Steering isn't quite as responsive, to be expected with another 2.5" of sidewall height
--Road noise is certainly present, not obnoxious, but w/ the rear seats down I can start to hear it around 45-50 and it doesn't really get any louder up to 75ish
--Overall handling is very simliar to the 255/55s, long sweeping cloverleaf style off ramps still feel very solid
--Speedo is virtually dead on!!! It's amazing! At 60 and 70mph indicated, the GPS states 61, and 71 respectively. With the stock tires, 70mph indicated = 66mph on the GPS
--The transmission is still relearning it's new shift points, I'm guessing this will take a few drive cycles.
--I
think I heard the tires rub one time... I tried lots of full lock turns back n forth and only heard some slight tire-on-plastic (fenderliner) rubbing while at full lock and the suspension drooping (making the u-turn to go down the parking garage levels)
As others have stated, this tire size requires a very slight (5mm) spacer on the front to clear the upper ball joint bolt. I purchased mine from AkataSpacer on eBay, $39.99 shipped. The quality of the spacers are great, not like many other cheapo ones I've seen. At 5mm, the factory "centering" portion of the hub still sticks through enough to center the wheels, and the lug bolts still get enough turns to not require replacements.
Now onto the pictures... I attempted a DIY spray wash, but at 32°F I only lasted a few minutes of high-pressure soap before calling it a loss and running through the automatic laser wash.
