Default Track/autox/dd tire suggestion

I'm about to purchase my new wheel and tire setup and cannot for the life of me decide on a tire. I autox at least twice a month in the summer and will proabably go to PIR two or three times this summer. All of this while daily driving..... I'm driving a 95 swapped impreza wagon w/fender flares. My last setup was a set of 205 kdw's. So I'm pretty sure a lot of tires in 275 width are going to perform better. Oh and price is also an issue. looking to spend under under or sround $800, the cheaper the better but with performance in mind. Thanks in advance.

I posted this in the wheel/tire section, but there isn't much traffic and I'm sure you guys know more about this.

I did exactly what you are planning on doing with my 05 STI. I used a set of Yokohama Advan Neova AD07 they are absolutely amazing in all conditions even the rain when they have tread depth left. I have gone through two sets of these and I can't say enough good things about them. One of my track day at PIR last summer was well over 90 degrees ambient and the track temp was hovering around 140-150 degrees. The tires did not start to feel greasy until the end of the 20 minute session.

Yes they are expensive but it is hard to find an all around tire. If you want to try something a little cheaper but with the same numbers and tread pattern look at the Kuhmo Ecsta Xs. It is a newer tire so not too much ratings floating around. I am probably going to give these a try for my next set of DD since I am going to R-compound for this season. Anyhow I hope that helps and if you want a ride to see how they handle on the street let me know. I will be home in a few weeks from overseas

Cheers,
Nick

So, you want a set of 275s, street tires, under $800, that will last daily driving, autoxing 2x a month and 2-3 events at PIR. Don't know how well they last, but Kumho has the Ecsta XS in 275/40-17s... supposedly better than the old MXs, at TireRack for under $200 ea. But they might be too tall at 25.7" The 255/40-17s might be a better bet at 25" tall and $151 ea.

Thanks so much man, I'll definitely look into these. Yea the kdw's felt pretty well at the track, but then suffered a huge amount when in the rain. My previous autox setup were a set of v710's, but the need for a different wheel and tire setup is forcing me to liquidate my dd's and track sets. Bummer, but I'm stoked for the meatyness. Thanks again and I'll hit you up sometime soon.

The W stands for WET in the KDW. Sure, driving in the wet on any tire is going to hinder performance... unless you have a tire like a Hoosier wet... and even then you can't drive it like it's dry.

Compound > Width

Get yourself some Dunlop Direzza Sport Z1 Star Spec's in 255/40/17 and call it a day. Only $670 for all four.

Pat L was looking at getting 15x10s made up. if u can swing it for clearance on your suspension and brakes getting a set of 275x15" would be an ideal competetion tyre size.

I understand that the W is for wet, but after heat cycling the kdw's they're extremely scary in the wet. I've talked to numerous people about the same effects. i.e. Jeff Barstow (3rd at autox nats).

So Compound > Width all day long? I wish there was a graph of some sort that shows width compared to compound, that would be nice. I have heard a whole lot of good stuff about the z1's and not too bad in price.

That would be crazy. Thanks for the advice. Where is Pat getting his wheels made at?

The Star specs are a great tire for auto-x but they are soft and every time I am too lazy to take them off after an auto-x and I drive them on the street for about a week, I find little metal things (screws, staples etc.) or glass bits stuck in the rubber. I did not have this problem with Hankook RS2's or Yoks.

Z1 Star Specs man, do it and don't think back!! I upgraded to them from more expensive summer tires, and they really are that good for the price.

Dunlop Z1's for sure. Love them. You could go with some of the newer tires coming out this year, but they are unproven compared to the Z1's.

Star Specs for sure! Guys out here are running as fast or faster on them, in time trials as they are on their r-comps. i have a set on my street wheels that im going to test out at the track in a few weeks.

I am in a similar situation, but trying to go to one tire for HDPE's and street instead of hauling the BFG R1 slicks along. Would you guys pick Z1's over Advan Neovas, Potenza RE-01R's, and Nitto NT-01's? Also considering the new NT-05's and Advan AD08's when they come out. Any thoughts?

If you could get your KDWs to hold up to a track day I would say you're pretty easy on your tires and may be able to get away with a long wearing tire. They are great street tires but I chunked mine to the cords at a track day and ruined them.

The Dunlop Z starts are extremely impressive for a "Street" class race tire but they do wear quickly on the track. They are much noisier on than the KDWs so beware. I had no issues with chunking and they are pretty fast (close but not quite the speed of a Toyo RA1). I do find that they wear out quicker than a Toyo RA1 and have more similar wear characteristics to the R888. I miss the Toyo RA1

The Dunlop Direzza SS are great tires for what you describe. I have ran them in blinding, pouring rain when there was water standing inches deep in the wheel ruts and they handled it great - far better than I ever expected. And they run very well in AX and probably at the track (I have not tried). They do not get as hot and greasy as other street tires with prolonged "spirited" driving either. Mine are even wearing really well, despite driving them on an AX lot that I swear is made of razor blades, rasp files, and blow torches. Same lot that corded my nearly new V710s.

ums tuning here in az. tested the nt-05 and star spec on their time attack evo, and i believe they were faster on the dunlop. they were really impressed with both though. i know they ran less than 1.5 sec slower on the nt-05 as the same size nt-01. pretty impressive.

Maybe due to the fact the StarSpecs > RTs?

I am curious if the RTs are THAT much off the pace (I haven't ran the Stars yet).

Yeah, I was just thinking with the price factor though, the RT's would be a bit cheaper, right?

i think the others are much better than the 615's, especially on the street.

The Z1's aren't much more than the Azenis, and the price gap is worth it.

Got a link? That would help remove another of the new tires from the running.

RE01R is more daily friendly of the uber street tires, the more comfortable of the bunch. They do well in the rain too, and you pretty much need a downpour and a bit of standing water to get them skittish.

You might want to be reading through Tire Rack's test results. They've all been tested...

The Z1 did better than the RE01R in every Tire Rack wet test. FWIW.

rt615's are almost 2 seconds off the pace when compared with Dunlop starspecs on an auto-x course.
