Hey everyone I bought a set of Mazdaspeed MS-01 and as of now I have the front wheels wrapped in Kumho Ecsta Supra 712 and the rears have Kumho Ecsta 711. To get to the point are any of you use/used Kumho Ecsta Supra 712 because I want to know what you think of them with firsthand experience and have them all matching all the way around. Thanks -Keith

 

kumho tires are pretty good
here's the order of performance

711 = bottom of the performance series I'd ride on them nice and easy, a bit harder than daily driven tires.

712 a little bit better but i wouldn't use it for long periods of time, i've reached its heat range fairly quickly

I've heard MX series are good and decently priced, try those if you wanna stay with kumho

 

712's are crap.
711's are even worse crap.

Please get some decent tires for your RX-7!

I agree with Ted. The Kumho MX is an excellent tire but the 711 and 712 are complete crap.
