I'm looking to change my front tires and my tires size are 235/45/17. Can you guys recommend me some good tires and where is the best place to do it?
I live in Louisiana btw.

 

I bought mine through Sam's Club (best price I could find). Check Tire Rack website for options, reviewa and prices. Once you settle ona tire you can prices shop around.

I have the Fierce Instinct tires on my car. I like them well enough. They are cheap so they do wear faster than some more expensive tires.

Also, if you have a Quatro you should consider changing all four at the same time. I changed mine two at a time as they were well within the allowed differenced (I think it was 3 or 8% but cannot recall for sure).
