can anyone tell me if there is any diff between them like speedo off harder ride .thanks just looked up tire size 205/50/15 looks close to stock size would i be right about this what about mpg would that change .thanks again

 

It's gonna be significantly harsher, cause the tire is way thinner. It's gonna feel like you put on 17's but these are way lighter so you'll probably get some wheel hop. They also make your mileage go up faster, you're going 60mph, but the speedo will read 61mph
