Hi guys I have a question I just purchased an 08 ltz and it has 3 oem goodyear ls2 and 1 firestone firehawk high performance all season tire. Do you think my mileage performance will be lower because of the off tire? Thanks!

Na, but having one odd tire isn't always the best for wet conditions. Two and two would be better.

Thanks Silver, I was wondering if it would affect my mileage I was thinking about just getting another goodyear ls2 so all four would be the same.:rolleyes:

I would, if you can't afford a new one Google used tire shops. You can get them shipped with 2/3-3/4 tread on it for like $80 or less I have seen when I had those tires.

Thanks Silver

No problem.

it shouldn't affect the mpg at all, maybe if they were different sizes but I don't think so.
