Kumho vs. Hoosier on 8" Wheels
 

Looks like from the National Solo results in B and C-Stock with the V710s on top I should be able to pick up a set of used A6s pretty cheaply, huh? :scratchhe

I believe we have a set of 285's for sale...

Any idea what a fair price would be?

Thanks,

Barry

PM sent...

Price? We'll probably be pretty easy ;)

As bad as I was, I believe that I was faster on the 285's than the 245 v710s. If it weren't for coning on day 2, my nationals finish would have been almost respectable. So, I would be interested in your 285's if Barry doesn't want them.

How do you know you were faster on the 285, did you run one set each day? How many runs were on each set?

c'mon Jason...'mo tire is 'mo better, right? :hahano:

I really thought the A6 compound was going to be better at HPT, but I'm starting to realize the more I think I know about this autocross stuff, the less I actually know...if you follow my reasoning.

I'll start running my RX8 on the 245 Kumho and see where it leads...

Jason,

That was poorly worded on my part. I should have written, "I believe I was faster." My times relative to known quantities were much better at Nationals, well at least raw times. They still sucked, but less so. I should strike my earlier comment given that my opinion regarding these matters really should hold little if any water and the comment was not based on data. The results speak for themselves, and your success has proven the goodness of the Kumhos.

I have had multiple sets of Kumho V710's, and they are fast and wear amazingly. At Topeka, they also probably warmed up more quickly. When I buy new in the future, it will be Kumhos, but I really like the Hoosiers in 285's, and if I can get in on a cheap set that'd be cool.

Congratulations on your repeat in BS. You were amazing both days, and I only wish I would have been able to see your runs.

I ran on the 245 Hoosiers for the first time at Natls. My times for the runs in which I didn't choke were pretty much in the range of where I normally run relative to Jason at our local events on my 710s. Given that the 710s supposedly last longer, I'd probably stick with them.

You didn't miss much, he's boring to watch. :mdrmed:

I really appreciate Clyde/John V's offer as I'd love to try the 285 Hoosiers. I have issues though (as those who know me will attest). :Eyecrazy: I'm lazy and since we're still in our dry season and Hoosier suggest not driving on the street with their A6, V710 it is.

I can't pass up Jason offer on one of his eight sets of (winning) :rock: V710s. Icing on the cake, he's on the Left Coast too so shipping is better. :angel:

hey jason got another set you could send my way?

Nothing to see here... :lol: One bummer about HPT was not being able to see the course.

The A6 does seem to 60' better at the pro and on cars that Kumho does not have a great size for, Elise etc, the A6 is the hot setup. But in every other case hard to beat the price and performance of the 710. :cool:

The A6 definitely accelerated and braked harder than the V710s on DC's surface, which is admittedly nothing like HPTs but it wasn't because they were 285's, the construction of the tire just seems to have more longitudinal grip. The 285 was something we just wanted to try out. Obviously we had our reasons to run the 245 Kumho at HPT, and the Boxster will be on Kumhos next year.

Has anyone back-to-back tested the 245 Hoosier and the 245 Kumho on asphalt?

I can't imagine they are close to the bang for the buck of the 710, but am curious as to how they compare, given that the RX8 is an application where the sizes are the "same" in both brands...

I'm not even aware of anyone that has run a 245 Hoosier, much less a back to back test. Closest comparison I know of was the Grassroots article on a Miata last June (?). The A6 was just a little slower than the 710 as far as best time went, but the variability between runs was much larger with the A6 due to it's relative intolerance to mistakes.

I ran the Hoosier 245s for most of last year. My opinion is that the Kumhos & Hoosiers
are even. Your driving style will determine which one is better for you. YMMV. :)

I know that Mark Allen ran the 245 A6 this past year.

Thanks, Mike. I had only heard about the "285 experiment" and was curious about the 245.

Not only saves me the extra $$ of the Hoosiers, but also saves me the hassle of changing stickers on the car and trailer ;)

wish the 710's had a 245/40/17 size available. I dont like the tall 45 sidewall they have with that size.

I still say the 225/40-18 Hoosier A6 will be better than the 245/35 A6

Anyone know what size Hoosiers the T3 cars were running at HPT?

The Rodert Davis Racing cars, top two, were on 245-40-17 Hoosiers. I am 99% sure they were on A6s as were many of the top SS/T cars due to the cold temps.

Thanks, I started to ask how the heck they're allowed to run 17" rims, then checked the rules and found this one new this year under Touring:

"Any wheel not exceeding the specified diameter and rim width on the vehicle’s specification line may be used"

That's a pretty liberal allowance, but certainly helps control tire costs.

Not new, been in touring as long as the C5 has, there were no 18" tires so they started just giving a max spec. They also have a tire allowance... The spec for the T3 RX8 is a 225 so they can run +/- 20mm.
