MX will be about $20 bucks or so more expensive I guess depending on size
While I respect orion's opinion, and have heard complaints about the RT215 in heat, I think they may be slightly exaggerated. The Sports remain a very, VERY popular tire in AutoX, and between runs, some people jsut spray a little cold water on them, and they're fine. I suppose on the track, there's more heat put on them, so that makes the difference, but I think it's tolerable, especially given the price of the Sports.
The MX's I am told provide less ultimate grip, but the heat factor is its advantage
I have never heard anyone refer to the ST-115 as an "Azenis Sports", in the circles i hang out with, which are pretty much all grip drivers, not drifters, Azenis Sport = RT-215, so I suppose that's just a personal thing. The ST-115 doesn't exist for me, it's not even a performance tire
MOST Kumho's (supra 712 and 711 ..or lesss) are crappy, cheap, "regular" tires that people run who don't care abo ut performance...i.e. most of the ricers on the street. So in that respect, Kumho could be called a Honda tire too... the MX is very good bang for the buck street performance tire. Kumho also makes some r-compounds which are good, too, but outside of this discussion. In the end, I don't think you can stereotype Kumho like you can Nitto, which is nearly exclusively run by the wanna be street dragger crowd (find me someone who seriously runs them on a road course...)
Come to think of it, most of the other Falken tires suck overall, hel...they make 20 inch tires for SUV"s...
Every company has some low-end tires for the normal folks...i.e. Bridgestone makes the all-weather shitty RE92 that came stock on the WRX, but they also make the best street tire around (price not withstanding), the S-03
