I have always raced T1 on ho-hos. I was actually having problems conveniently getting ho-hos so I decided to order a set of Kumho V710's to try. Onlinetires.com within a short drive got me these. This is how Kumho individually wraps and bands their tires to the customer. They seem to take pride in their tires and want to protect them in shipping. Is this attention to detail needed? I don't know but I have been buying race tires for a couple decades and I have never felt like a manufacturer gave a rat's a$$. Well it appears Kumho does. Kudos to Kumho.

I've bought my fair share of Kumhos and never received any packaged like that.

I think you will like the way the 710 holds up through a session. I think they can take a little more heat than the A6.

I like to reverse the rotation on mine every other day. This helps keep the joints from separating I'm told.

I found the 710's to be extremely predictable, even after numerous heat cycles. They didn't have the initial grip of the A6's but they didn't go away like the A6's either.

I used them for years until Hoosier started the contingency program back in '08 or '09.

Let us know what you find with them. After Hoosier has made the days of payloads of tires scarce, the 710 is certainly a very viable option.

I never got any wrapped like that. I was always happy if they were less than 2 years old.

Dates on yours?

I tried a set of 710s last year and am still running them! They are holding up great, they have about 22+ sessions on them and the rears are not even to the wear bars yet. I think they stick as good or better than the R6s. Just my .02 JD

oldest tire is july 2011. I really like the bead finish on the kumho's. HoHo is terrible with all kinds of casting flash on the beads. That makes for leaky Ho-Ho's. I solved tires moving on wheels by mounting tires with hairspray or beadsealer when I get a really bad one. I got my own tire machine. Every racer needs one life is so convenient when you want to flip tires.

Oh I have tried to order kumhos before but they were on national back order every time I tried. I got a theory. I asked the supplier why 710's are hard to get. His reply was kumho makes intermittent huge batchs of tires and they (supplier) try and buy as many as they think they will sell. So perhps your old tires were the end of a run bought late before they ran out. That does not bode well for running Kumhos because we all know fresh rubber is magic. HoHo seems to be in production constantly. I don't think I have bought a HoHo more than 6 months old and I'm pretty sure most of what I buy is only 3 months old but don't quote me on that since I never really bothered to keep track. If Kumho does batch process maybe that explains why some people really think these tires are great and others are not impressed. New "Old" rubber is never impressive.

Geez that's great. I don't expect anywhere near your life on the 710's. They have a wear rating like the A6 Ho-Ho and those are only fast for one race and then OK for Sunday's race unless someone else is running new stickers. New to one race old will cost you a 1-2secs on tracks around here. After a weekend the A6's are good for practice. They are still fast but not race pace fast. I'm cheap I'll run mine to the cords getting progressively slower. If it gets too painful I'll dump them for new rubber = magic!

That silver wrapping must be something new.

That's why I don't run Kumhos. They really aren't dedicated to the business and by mid-season you might not be able to get tires. I had one blister really bad on me and I couldn't get a replacement, so in effect four tires were useless.

That is exactly my experience with the A6.

The Kuhmos last longer, but JD is using them for DE.

I have found that V710s don't have the surgical preciseness of Hoosier R 6s but keep their peak performance longer i.e the full 16-18 heat cycles that the manufacturer claims, unlike Hoosiers which seem to start to drop off almost immediately. On my car they seem to perform just as well as the Hoosiers in all out grip but aren't as pleasant to drive.

Don't really know if an Autocross run counts as a full heat cycle ( I suspect not) but in Time-Attack, each 5 lap run does, which means V710s are not all that suitable. OTOH for full out wheel to wheel racing or longer HPDE sessions, they are great.
