OK Iv'e read it all Falken 615 are the best. next person sez fk no greasy when hot only for autox.
I'm not going R compounds can't go there.
We have a extra set of wheels to put track tires on for road course events.
Boss will do 6 to 10 events this yr, don't care about miles, tires and custom rims are for show events. and yes she squalls the hell outta them.


Lets hear it.

 

I hear good things about the Nitto NT01s and the REO1R.

 

Dunlop Direzza Sport Z1 Star Spec

I'm about to buy these for daily/track use. check out some of the reviews HERE

 

Can't compare race tires to street tires lol.

As far as street tire wise, RE-01'r, RT-615, Dunlop Z1 Star Specs. the Z1, and RE-01'R are better than the falkens.

As far as track tires, NT-01's are among the best.

 

I don't know why your're writing off R-compound tires for HPDEs. You can get a set of Hankook Z214 DOT R-compound for less than the cost of many of the street tires recommended above. If the roads are dry you can drive them to the track and back. They make a world of difference and are pretty forgiving. I'm using 245/40/17s but you can go wider. If you have a set of dedicated track wheels, why not put on some R-compounds and see what your RX8 can do.

 

I'm not sure he knows what he is talking about.

Thread title id HPDE and the thread talks about Auto Cross.

Two different things.

 

I'll explain further then, Ive heard the rt615 were good tires but when used on a road course and they heat up they tend to get that greasy feeling as when used for the short autox runs they tend to be a very good tire.
I didnt want to go with R compounds because both tracks we run are 140 miles away and dont want to use the tires up on the highway. Maybe i'll just take another vehicle and swap wheels when I'm there.
Damn maybe I did know what I was talking about.

 

You wont use a lot of tire driving to and from the track so you could get the R-compounds, put them on, drive to and at the track then swap them out at home. That what I do with the NTO1's. They are DOT street legal tires and work excellant at the track.

 

FYI, All 4 spare wheels/tires fit in the back seats, standing up. Swapping tires at the track is a very viable option.

 

Nitto's new tire, the NT05, is a max performance summer tire. The UTQG is 200AA A with a W speed rating.

 

The decision as to what tires will work for you also depends on your HPDE level. If you're novice or starting or only a few sessions a year, most any of the Ultra-hi performance tires mentioned in the correct size on good wide wheels (>=9") will work fine, after all you're learning and these types of tires will tell you when you're screwing up and scream for mercy.

As far as the RT-615 getting greasy, sure and so will others if your running in a hot climate and going ***** out with them on a tight course with lots of turns and little cooling off time on striaghts. Big deal, they're still good tires for HPDE events as are the others.

R-Comps are a sure winning combination on the car, just throw them in the back (after removing the seats), and head off to where ever you please. Use tire totes and everything will stay neat and pretty inside the car.

R-comps are so so so much nicer from a handling perspective compared to ANY street tire, bar none, but some say, and some clubs limit their use by novices or those that aren't running solo. Check the rules where you will run before buying.

Either way have fun, stay relaxed there's a bit to learn from your instructors, and take in and assimilate and it can get overwhelming at first.

I ran two sets of RT-615 thru on and off track before graduating to NT-01s and no problems with either to speak off. I would stick r-comps in the back if you have to go more than 100 miles round trip.

 

Haven't taken them to a track yet, but I've been very satisifed with these Sumitomo HTR Z III's. I wouldn't be surprised if they worked well in this application. Still don't know how long they are going to last me. How wide can you go with a tire on stock rims anyway?

 

I use the Sumitomo HTR Z III as my street tire, and it's a great street tire. I would not use it as my track tire. I'm sure it can sustain some track time, but it would not be an ideal "track day" dedicated tire, especially when compared to the ~200 UTQG tires like the RE-01R, Z1, RS2, etc.

 

I like Kumho's MX or Perelli nero zero.

 

OMG, Information overload. hehe
THX for ya time and ideas, much appreciated
