I'm using them for my 97 turbo GSR and plan to use them only for HPDE events. Any experiens with these would be great! Also, what hot/cold pressures should I try?

 

Very difficult answer.

1. It will depend on how well the tires are heat cycled
2. Depends on how they are driven
3. Depends on the track
4. etc. etc

With an open question like that I will give you an open answer: From one track day up to 8 track days or more.

 

I only have hearsay for you right now, but I'll know in a month. What I've heard as far as on-track use goes is that they are less camber-sensitive than Hoosiers but generally wear faster. So, you're probably looking at faster wear than a set of Hoosier R's, all else being equal, but if you're camber-challenged you won't cord the outside edge as fast as a Hoosier.

 

How long do they last on the car, or how long do they last before they are recalled?

They were heat cycled by the Tire Rack. I'm running -2f and -1.5r camber. Is that enough?

 

That depends too. Weight of car? Tire size? Rim width? Suspension setup?

And then you still can't say how it will be because you may drive the car with the nose sliding all over the place or you may drive it with the *** out or...you get the picture. Some basic info about the car would be helpful besides it's b00sted, y0!

Well to tell you the truth, these are my first set of R comps. I have 3 track days under my belt. Many more this year... I do tend to brake late and deep. I have ohlins coilovers with 12k front and 8k rear springs, 23mm rear sway and kosei 15x7's. I'm running full street weight at about 2700lbs with me and a full tank of gas... Any other info needed?

 

If you have a camber kit I'd stick another half to whole degree of negative camber in the front of the car given your moderate spring rates, but the aforementioned round shoulders on the 710's may save you if you don't.

I wouldn't expect to get more than 2 weekends out of them on a turbo, 2700 lb Integra, and that's being a little optimistic. I honestly wouldn't expect to have 4 un-corded tires by the end of a 2-day track event, anything more than that is a bonus on a car that has a lot more weight and power than tire.

Just don't expect miracles. They'll be really, really fast though.

 

sweet!! Thanks... ANy idea on what pressures to run with my setup?

 

Have you done a lot of testing with these tires? I just bought a set, and expect/hoped to get two race weekends out of a set, if not more.

 

About 38 psi hot in front, rear pressure will depend on your suspension and how much you like to rotate your car going into corners. In the showroom stock cars (all stock except comptech rear bar) we were at 42 psi in the rear and going to try higher. In general the 710's don't like to go over 40 hot but you may have to go higher in the rear to make the car handle like you want.

In a month I'll be able to tell you for sure how they wear on a 2300 lb with driver SM but until then I'm just parroting other people's experiences and using what I know from my own experience with Hoosiers and the characteristics of the 710's relative to them to infer something. In other words, I'm basically talking out of my ***.

Can we discuss cording the outside edge for a second? I've got some questions.

My cars are both aligned to the factory spec. I have found that the Victoracers VERY quickly cord the outside edge, even while there is tread depth in the middle of the tire.

The Yokohama A032R don't do this. You can wear the outside edge, so that it starts to round off, without belts showing. You can keep driving on them until the main part of the tread shows belts.

I haven't yet worn out a set of the Toyo RA-1, my current tire of choice, so I don't know whether they do this or not.

Now, my questions...

- I am assuming that tires should be replaced when the outside edge shows belts, while most of the tread shows tread depth. Is this correct?

- I have also found that, because of the predisposition of the Victoracers to wear the outside edge, they don't last anywhere near as long as the A032R. Like less than a third as many track days or track miles. Comments?

- Do the Ecsta V710 wear the outside edge quickly, while most of the tread still has tread depth, like the Victoracers?

- What about the RA-1 - what is their wear pattern? Will they last until the main tread wears down past the tread and belts start showing, or will they start showing belts along the edges while they still have tread depth?

- Any other thoughts about showing belts on the outside edge vs in the center of the tread?

TIA for any responses...

 

When the victoracers are half worn, flip 'em on the rim.

 

Since we're discussing tyre life...

For all you lovely people who run Toyo RA-1s... what's your average life of the tyre? 2 race weekends? 5? an entire season?

That is, assuming they are shaved and heat cycled properly?

I've thought about trying them (been a devout Kumho fan). This will be on a 1910lb CRX (2080lb race weight w/ driver).

Could you dial in some more camber? It seems to me that you are trying to fix the wrong end of the problem.

Well, I also use both cars on the street, so I don't want to go too wild.

 

I do what .RJ said about the Victoracers:
If you have an idea how many events you can expect before showing belts on the outside edge, flip them "inside-out" when you get to half that number. Works like a champ.

You can run at least -2, probably -2.5 or 3 deg of neg camber before you start seeing any funny wear.

 

If I run -3 up front, what should I run out back?

 

I would leave the rears where they are or go to -2.

 

I had been searching for some info on unusual wear on the V710's as I've experienced both blistering and delamination on mine.

I heated cycled them at Mosport for roughly 10 minutes then let them sit for two days. I have one full race weekend on them now and two of the tires have shown varying degrees of degradation. One tire is missing complete patches of rubber while the other is showing the first signs of delaminating on the outside edge.

I've heard that the V710's can be quite fragile, especailly if overheated. What I don't understand is why they would begin to fall apart on me on a track that doesn't eat up tires? Has anyone else had similar experiences with these tires?

 

Honestly, I don't have anything to contribute on the V710's but after being underwhelmed by the Victo's and then disappointed but the V700's I've given up on Kumho for a track tire. I understand that the V710 is an excellent tire for asphalt course autoX but with all the tire recall problems Kumho has had lately, I'm stearing clear of them.

Christian, who's currently on R3S04's and will be trying Toyo RA-1's shortly...

 

I think I'm with you one this - I was terribly unimpressed with the Ecsta V700's and to a lesser extent the Victoracers and now this just makes me want to consider another tire company altogether. I run the RA-1's as my intermediate/wet tires with great success. I know a couple people here that are running the Goodyear GS-CS without problems. I fact they are giving very favourable feedback - good longevity, excellent grip. I'll probably give those a try next.

 

I'm the only guy in my division (to my knowledge, and excluding Tony Rivera who is obviously a robot) who's been on the podium and ISN'T on Hoosiers. The V710's are great tires, really.

I would expect them to wear pretty well in HPDE use. I've been getting at least 3 weekends' (12-15 sessions) of use out of each set of V710's on my Miata. They seem to get a little slower after about 10-12 sessions of ~20 minutes each, but I have yet to cord a V710. The tires I have that have over 10 sessions all have more than half their usable life left, at least 2/32" of tread.

In other words, they wear great and are fast in road course conditions. For a heavier Honda, I'd use the 225's.
