I'm kinda tired of changing tires for the events. r tires for dry, street tires for rain, you know the deal.

I run victor racers so their good for dry and act as intermediate rains. but after they wear down, they are no longer good in the rain....

so I'm thinking of more of a street tire with deeper tread. maybe kumho MX's can act as a dual tire.....?

there must be a better solution for us who don't need every split second, and would rather relax some in between sessions..

I don't have personnal experience with these yet but I was looking at the Toyo RA1's. Here's a link to an article on them.

Larry,
I work for Kumho tire in the Motorsports Division and I would recommend the MX's. I use them for our ride and drive programs and they work very well for street,track days and rain. The price is right too on these through the TireRack or a local dealer near you.

Just my .02 cents worth,

Aaron:
What is the recommended hot inflation pressure for the Victoracers? Can the tire be dismounted and rotated from side to side to maximize wear? Can you reverse rotation? Is that splice induced tear that runs horizontal across the tire a normal occurance. These were used scrubs that I bought and refurbished(Traction V Treated.) I thought they ran great when I took them out last week.

I ran the RA-1s on my 1995 Z28 ran them on the street, autocross and HPDE like them alot.

Solid choice

Sidney,
Hot pressures should be no more than 40! Ideal would be around 35 hot! Yes you can flip these and run them either direction. I did at Mid-Ohio this year and they worked just fine. As far as the horizontal line, that is where the splicing process comes together and we have had no problems. I know that it doesnt look pretty, but you can run them.

P.S What size are you running and what year Corvette and mods?

Thanks. 94 LT1 with the 275's.

larryfs, I've never graduated to DOT-R's and am still running street tires
after almost 4 years on track. But I've driven on full race slicks in open
wheel cars and I'm guessing that if like me you never left street tires
on the Vette they do ok, but if you've had better going back will come
up short somehow. Not only less grip on corners but less braking as
well. I run the Kumho MX's and think they do a great job for the price.
That was after going through the original run flats on my coupe, then
trashing some Michelin PS run flats in just a couple days and switching
to a set of Z06 wheels for track days. That led to about 3 sets of GY
super car OEM tires and then decided to cut cost some and ended with
the MX's for the past two years. They go about as fast as I'm ready
for.

Aaron great to see a Kumho rep here. I have the V710s and have a slit across the tire I guess now reading the comments here that is the splice line.

Is there a problem with running the tire with the splice line? It made me nervous so I bought a new set, but if it is common for the tire then I will continue to use them and just watch the slit....

thanks

larryfs, at Sports Car Driving Experience (Corvette school) we have run many different brand tires in the past few years and NONE compare to the KUMHO MX's. The grip, rain or shine, is the best of all the tires we have used in the past. The MX's is by far the best dual purpose tire and for the price you can't beat it. KUMHO is the exclusive tire of choise at [URL=http://www.corvetteschool.net[/URL]

Just what Henry said! See you in a couple of weeks at Roebling.


As for you Bob, enjoy the Kumho's and sorry about the ugly splice line! Run them and enjoy.

the blur

Will Kumho offer the MX in a 315/17" ?
315's / 17 are a popular choice for the C5 rear.

The 9/32" 's of tread seems very nice for full wet.

rasrboy

285/40R17 is the closest right now, but we are working on a bunch of new sizes for spring of 2007. Hopefully that will be one of the new sizes.

Can you share what other tires were run for the comparison and what the issues were? Thanks.

Wicked Weasel

great help.....

now how about a random drawing for a free set of V710s

rasrboy

Riiiight!

Wicked Weasel

well it was worth a shot

can I suggest a 315/30-18. I'd be more than willing to test them for you

I've used the MXs for daily driving, AutoXing, and track days. They're not 710s by any means, but a great all-around tires and the price is great for those of us that tend to use up tires pretty quickly.

We need more 315/17's, please do!
