Anyone familiar with the GT RADIAL CHAMPIRO SX2 or the FALKEN AZENIS FK510

Trying to decide on a new set of tires. What came with the car, Barum Bravuris 5HM are cracking, after chunking on a couple autocrosses. Have not been good at any particular thing.

This is for a Kia Forte SX, 5 door. 215/45r17. Driven less than 10k miles a year as a daily, kids to school etc.

Do a few sessions of autocross and rallycross per year. Rallycross in North Texas/Oklahoma favors summer tires as it packs down hard.

Tires are a bit different, but the GT SX2 200tw is also less expensive at $108 if it last a couple years.

The falken fk510 at $147 and 300tw seems more what I should get.

The falken 615k+ is just a few more dollars but I'm worried it would wear out, not do great in cold weather etc.

Not sure I need a 200tw tire as I just race for fun, stock, on HS, but the GT SX2 is tempting. 

So, any first hand experience with either?

Or, opening big door, any other tires recommended? Up to about $150 a tire, that would not destroy itself in autocross, cold weather ( rarely ice but enough days below freezing) and be controllable in the rain 

Thank you all.

We ran the Falken FK510 on our LS-powered 350Z for a drift event. 

You're wanting an allseason. Summer tires do not handle cold temps well, so both the tires you have listed should be out. 

For high performance all season (a bit of an oxymoron) I would go with a Kumho PA31 or the Hankook Ventus V2 or the Falken FK460. I would also bump to the 225/45. There's enough factory wheel there for them to run. I ran a set of the FK460 predecessor tires on another vehicle for a few autox. They are not very sticky but no all season is. 

As cheap as wheels are for that car (5x114, 17x7/7.5/8) I can't recommend enough a second set of wheels for summer tires and then the all seasons for winter. Steering response, grip, transistions are sooooooo much better and make the car enjoyable and a set of RT615's will last all summer long doing double duty. 

In reply to David S. Wallens :

Thank you, it does point out the tires wore like iron. Good to know.

In reply to bobzilla :

You are probably right on both points. An all-season would probably suit me better and having a second set of wheels and tires would give the most benefit.

I wouldn't mind an all season if it's an improvement over current tires, which is easy enough and they don't chunk the outside edge due to heat. 

They probably chunked also due to my novice driving style and lack of camber.

I'll look into the fk460's. 225's are only $2 more a tire, I was contemplating going up.

Thank you

In reply to NoBrakesRacing :

Is it a first gen or second gen Forte? The first really liked the 225's. The second really likes 245's on 8's.... just sayin'

2011. First generation. 

I had FK510s a few years back. They're a good value choice and I liked them. Based on tire rack testing I think they are a solid option.

Thank you, 

What would think of them for a daily driver? I do have other vehicles if the weather is bad enough.

About how many miles did they last you?

I had them on my daily driver, but I didn't have them for long enough to be able to give good information on tread life. My impression was they were well suited to fun road use. They had very solid dry and wet performance. I didn't use them on track, or autoX.
