Does anyone have experience with the Kuhmo V700s? I want to use my stock rims to mount them. The closest sizes are the 225/50 for the 16 and 245/40 for the 17. Has anyone tried these tire sizes?

Those sizes are not recommended. The front size is too large (outer diameter 5.3 percent larger than stock). It will rub on the fender wells and it will set off the traction control. The rear is the stock size, of course (but I don't think it's even available for the V700).

Kumho has two models of V700 track tires, the VictoRacer V700 and the Ecsta V700 (I assume you know that both of these are for track use). The Kumho Ecsta V700 is available in sizes of 205/45-16 front and 235/40-17 rear and these sizes should work fine on your stock wheels.

Thanks for the help. I'm trying to autox the car, a '94 coupe, and I'm having trouble finding good track tires for stock rims. I have two sets so one can just be track only. It seems the tires of choice out there in my class are the Kumho VictoRacer and the Hoosier. Smaller cars are using the Falken Azenis Sport. Falken actually has sizes that fit the NSX and I bought a set. After 3 events, 3 practice sessions, and 1 school on them I'd have to say that they're better (and a lot less expensive) than my Pilot Sports but not good enough to go after the Kumhos and Hoosiers. Since the rears will be gone shortly, I think I'll try the Ecsta 205/45-16 and 235/40-17.

Any other tips or suggestions you have on track tires or autox, please feel free to share.

Thanks
 
The Falken Azenis Sport is not a true R compound tire, although the tread pattern makes it look like one. It's a good handling, inexpensive tire that's well regarded mostly for street use. For autocross, I think you'll find any track tire to be a step up from the Azenis.

If you're planning on using the tires primarily for autocross, why not go with the Hoosier A3S03? It's designed specifically for autocross (which means it doesn't need the warm-up laps to really grip well like most road course track tires do). It's available in 215/40-16 front, and 245/40-17 rear. That would be my first choice for autocross use.
 
I would recommend to use Kumho ecsta V700 205/45/16 in front and Kumho V700 Victoracer 255/40/17 in the rear.

I used it before and was happy with it.

Thanks for the reply.

I agree that Hoosiers are the way to go but after pricing them, I think that my skill level won't match the expense of the tire. I like the idea for now of mixing the front and rears between the two Kumhos V700s. Did you fit those 255/40-17s on stock rims? The stock 8 1/2" is at narrow end of that sizing and I'm wondering if there's any well rubbing. The other reason I will probably not go Hoosier right now is I have to drive to the event on the tires I'm going to run on. I know, I know. But haven't figured out how else to do it for now. At least the Kumhos have some tread. I change tires at home and drive very conservitally to and from. So I'm going to be going through tires like no tomorrow anyway at this point.
 
I strongly disagree with using different tires front and rear. This is generally not advisable, because different models of tires will have different traction in different conditions and make the handling unpredictable. You're also better off making the rear slightly narrower (235 rather than the stock 245) since that is what you are doing in the front (205 rather than 215).

However, I would still consider getting the Hoosiers. They may be more expensive, but it's a one-time cost (you'll probably be able to use them for a long time) and they're definitely the preferred tire for autocross, since that's what they're designed for.

If you don't want to spend the money on the Hoosiers, then I would definitely get the 205 Ecsta V700 for the front and the 235 Ecsta V700 for the rear, and not use mismatched tires as Andrie is advising. (Sorry, Andrie.)

Why don't you bring your tires to the autocross in the car, and mount them there? Try it and you'll see that you can fit a rear tire in the trunk, slide the passenger seat forward and put a front tire behind it, slide it back again (won't move much) and put the other two tires on top of the seat. (Transport the tires in 33-gallon leaf bags so they don't get your car dirty.) You might not be able to do this with the Falkens because they are notorious for being much larger than the same size tires in other brands, but you should be able to do this with the Hoosiers or the Ecsta tires.

No need to be sorry. We have differing opinion, ad you certainly entitle for it.

I'm just stating the fact, that I tried them, and used them and tested them with no ill effect. If anyone doubt my skill, they can see the OTC result in a few month.

Don't worry, Andrie - no one doubts your skill. (For those who don't already know, Andrie is one of the more prolific track drivers among NSX owners on the West Coast.)

Andrie, have you tried fitting a set of tires those sizes inside your car to take to the track?
 
Thanks for the input. I think I'll try the Ecsta for the time being. I'm trying to get them tomorrow. I have a ProSolo event this weekend and I'll let you know what I think. I'll have to experiment a bit about loading the tires, though.

The tools that I take to the tracks don't allow me to stuff any wheels in the trunk.

FWIW, I have a big Rubbermaid bin (for tools, brake pads, etc) that occupies the rest of the trunk, and a small hydraulic jack that fits on the passenger side floor. My helmet and overnight bag go in the interior, on top of the tires. Small stuff goes in nooks and crannies.
