Kumho Ecsta V700 tire pressure
Next weekend my Evo will be wearing these tires for the first time for autocross.
I purchased size 245/40-17 and I'm wondering what pressure I should run them. Anyone have good luck with these tires?

I'm not sure how they compare overall to the Victoracer in terms of inflation/overall compound..but as a comparison I found the best pressures for my Victo's at Kentucky Speedway to be 42 frt 35r. At other locations like Scarlet it would probably change a bit since Ky Speedway is abrasive non sealed blacktop.

Looks like I'll have to play around a little bit. Next weekend we'll be on the airstrip at Ft. Knox, should be an interesting test bed for me! ![Smilie](https://www.evolutionm.net/forums/images/smilies/smile.gif)
By the way, good job the other weekend!
I'm hoping to make it up there to some more events, I really enjoyed being in the company of so many Evo's and Evo owners!

It was fun running with so many Evo's.
You missed Sunday. We were expecting to see you. I finished 1st and Greg was 2nd. I improved on my times a little running 40.8-9's

I had an awful time with the V700s last season. The performance was decent, but I kept beating the hell out of the outside shoulder. I destroyed one after only five events and corded two more before the season was done. After tearing up the first one, I bumped my pressures up a bit and that seemed to help. I had been running around 42 psi hot IIRC on the front and raised that 2-3 pounds. Maybe even more pressure would have saved the last two, hard to say. My solution for this year was to go to a bigger front bar and Hoosier A3S04s. I have only run one event on that setup, but it seems to be much better. Time will tell I guess...

WOW! 48psi?! I am only judging inflation by sidewall rollover right now. The rear doesn't get enough rollover unless I run 35 psi Anything over 35psi and it doesn't roll to the sidewall markers/arrows. I'm considering even less pressure in the rear to see if I can get the inside edge to make better contact..since I'm losing an inch of the contact patch
A bigger rear bar may help me also. I think I'll run upwards of 45psi at the next event in the front.

I'll start with high pressure ~ 45-48psi and work down from there.
I'm planning on getting a comp. alignment done. I'm thinking -2 camber (more if I can get it), -1.5 rear, a smidge toe out in front, and 0 toe in the rear. I'm hoping the -2 in the front will help with the "killing" of the outside edge of the tire.
I hope I can get it done before this weekend.

I have run Victoracer V700 245/45-17's for one track event and one AutoX this season. At the track we found that 42 hot seemed to be what we needed to resist rolling over too far. I think we ran 42 in the rear as well.
At the AutoX a few weeks ago I ran 41/36 and that seemed to work well. No noticeable rolling over, at least no worse than what was already scuffed up from the track day. I think I'd be happy running those pressures again...
The insides of my tires definitely have less wear than the outsides, nothing that a flip can't correct after a while, though I guess more camber would be nice, I'm already pretty maxed at -1.6 all around. Could get more in the rear but we elected to make it even front to back.

I run -.8 in the rear and I'm now thinking a little more neg. camber might be a good idea.

Go figure...
I think Toyo may be my next tire...
BTW, this was at VIR, not an autocross...

What's the most negative camber that can be dialed in using the stock adjustment? -1.8 to -2 deg? I get wear on the outer edges on my stock street Advans. How much camber can you dial in before you start to feel tramlining?
Jason, BTW, I had a great time with you all guys at VIR. I don't think I could have wished or hoped for a better first experience at the track. I'm looking forward to meeting up with you guys at an event again sometime this year.
