Just an update on the Kumhos on my '05 XB. Now at 20k mark they are starting to lose their wet gripping traction. Wet traction is noticeably reduced with slipping and sliding around corners and when taking off from a stop. Tread wear is light and I would say they could run another 20-25k but traction is reduced. They roll great on dry pavement and still handle great but the wet traction concerns me. I will run then through the summer and probably put on a set of Michelin Hydroedges in the fall.
#21 of 22 Wrong Tire Placard
Mar 07, 2010 (6:03 pm)
Hello: Looking for feedback...I purchased a 2009 Scion xB with the optional 19" TRD wheels and "recommended" Toyo Proxes 4 tires. The original wheels/tires were 205/55/R16 and the original tire placard calls for 35psi front and 32psi rear. Long story short, I've been running these tires at 35/32 instead of the proper 39/37 (Toyo and Scion Customer Service have confirmed these numbers). Scion says that the dealer should have replaced the original placard with the proper placard. The dealer says they never got a replacement placard, blah, blah. I've got over 18K miles on the tires and they show severe signs of underinflation (shoulders worn down while center hardly worn). Looks like they are trying to "scimp" and give me some prorated value while I contend that the tires have never performed like they should because they were underinflated. Also, I had to replace a rim a few months ago after hitting a small pothole...I'm thinking if the tires were properly inflated, the rim wouldn't have been damaged and I wouldn't be out ~$500. thoughts??

I've never seen a dealer replace the original door sill placard, and I've bought a few wheel upgrade packages. At a minimum, the salesman should have briefed you on the pressure difference. I ran into this initially back in '89 when the pressure changes on the performance tire and wheel I purchased from a Chevy dealer were not mentioned and I did the same thing that you did. After I complained loudly in the service bay they replaced all 4 tires and it cost me $75.
After that I always ran the pressure 5-6 psi higher than stated on the door for better fuel economy and handling.
