ive been trying to look for some low profile tires over the internet. But i cant find any because they never mark them as low profile.

What are some sites that sell low profile tires and how can you tell if they are low profile?

Look at the second number. I'll use my tires as an example. 245/45/17 245 is the width of the tire in MM, 45 is the hight of the side wall, 45% of 245mm, and the 17 is the wheel size. The smaller the side wall the harder the ride will be.

do u have low pro tires?

A bit lower then stock. I don't want tires like that on my car, they hurt performance and are hard on the transmission. I'm all about performance.

If i wanted to get 20" low profile tires and rims what would the measurments for the tires and rims exactly be?

I think stock size is 225/65/16 And if you go with a 245/40/20 that will be very close to stock size. This comes in at .7% off. So if your speedometer says 60mph your going 60.4mph
