Kuhmo Mx or Falken R-615 ?

[gandrade1]

Hi friends,

I finally went the extra mile and exchanged my 16'' winter set (new tires included) for a set of track, 17'' OEM Boxster rims. I run a 18'' OEM set with Conti's as a 'regular' set.

It is now time for the tires... Since this is going to be a track set and I am not a skilled driver I have narrowed down to 2 options: (1) Kumho Ecsta Mx; (2) Falken Avenis RT-615...Thank you so much 'Topless' for all the guidance...

I am running 225/45/17 and 255/40/17 in the front and rear respectivelly. My questions are:

(1) Anyone with experience with either tire in a Porsche?

(2) I am basically looking into DE (track) events, will any of these be better - sometimes it does rain during track days in NJ, but I will probably not push to the limit in these occasions?

PS: Bridgestones RE 01-R are not included in the list for they are in another price range..

All the best,

Gus

I have tracked and autocrossed on both tires on an 05 STi. The Falkens get hot way to fast for DE's and get greasy. They will also wear out a lot quicker than the MX. The MX is widely considered a good street tire for DE/track days. They handle heat well, wear well, and have good wet traction. Though the MX's will be a little slower for the first 3 laps, after that the difference goes away. RT-615 is a great autocross tire in street tire classes for the price, but needs to be sprayed after the first few runs to cool them down. Of those 2 the MX is a better bet for you. In a year or two when you hone your skills and are ready to start really going fast, you can pick up a set of R comps.

You are welcome Gus.

I have not run these tires but several friends (track hounds) do and they mirror the observations of Silver Arrow. The Falkens are a good low cost AX tire and are sticky right out of the gate, but they get hot quick in continuous lapping. If DE's are your focus the Kuhmo's are probably a better choice. Good luck. Drive safe.

I have run them both, but on 911's. I use the 615 as my street tire on my mostly track 911. They do make a better autox tire than DE tire as they do tend to go away with a little heat.

I ran a DE a few years back with the MX and for a street tire it held up pretty well and remained fairly consitent throught out each session.
