Tires & Wheels

[ceatock at sympatico.ca (Chad Eatock)]

I understand that it is generally accepted that 195/50/15 are the best all around performers for our rocco's.....what tire would a 15x7 rim be able to accomodate without rubbing or decreasing performance on the rocco.....what constitutes lower profile tire?  are 205/55/15 lower in profile than a 195/50/15?  Please inform me as I am not up to snuff on my rim/tire knowledge....I also want to get some sweet ass rubber and shine for my rocc!!
Lemme know what is what!!!
