I have a 2010 package 5 with the Advanced Technology option. I love all the gadgets and use them all the time. I have about 2000 miles on it and enjoy it - with the exception of the much rougher ride than my 05, and 06 Prius. Any ideas to get more rubber on the beautiful 17" rims? I dont like the lower profile tires at all and would like to get more rubber between me and the road. Will taller tires work or will they screw up the speedo and other electronics?
