Only real valid data point is if someone has a test and tune with both tires and is generous to let us all know. Both sizes wouldn't hurt too. Bueller? Bueller?

I've seen DS beat CS on a few occasions where the course has lots of fast (50-65 mph) transitions (ITR vs Miata). So if CS>BS and DS >CS, then DS>BS (not likely, but it's possible). Holy cow, I haven't used association in forever... hahaha.

Most of the time I would not use natls results but in this case AS, BS and DS all ran within a heat of each other and on the same days.
AS 101.697
Steve 102.202
BS 102.396
DS 105.854
With the low grip surface the C4s power could not be fully used, with more grip AS would have been faster.
Sorry if you get beat heads up in the same conditions by a DS car you are off the pace.
p.s. CS ran thurs-fri after more rubber was on the track and also ran a 101.697.

Other than that, yeah. CS has beaten BS and DS has beaten CS, but can anyone point to an event with drivers worth comparing in developed cars where DS beat BS (weather or conditions notwithstanding)?

It is always hard and most of the time useless to compare one class of cars to another, that is why cars are in different classes. However with DS VS AS/BS/CS you get to a point where the vehicle dynamics are so different that with equal drivers you will not see DS beat the others in the same conditions.

This has been quiet for a little while. Are 710 285s the way to go???? I know it will depend on conditions but just trying to get more information from you all! Any input is appreciated. Has anyone actually weighed a 245 and a 285 kumho? Hoosier?
#59
When I weighed the 285 HoHo (new) and 245 Kumho (65 runs), on the same scale, they both weighed right at 22.8lbs.
I think many of the Tirerack's weights are off, a bit. For example, they have the OZ Ultraleggera at 18.4 and mine only weigh 16.0, or a bit less than Jason's unobtanium SSR's

245 21.7lbs
285 23.7lbs
You would think with that light of a wheel you would be faster.

I just mounted some 245 V710s on some BoxsterS wheels, I should have weighed one.

for the person asking about using 285 V710s, getting a new set to seal the outer bead and inflate on an 8" wheel is something that 99.99999999999999999% of the tire installers in the US are incapable of achieving
any good race shop/tire installer can get 285 Hoosiers mounted up, the sidewalls are quite different between the two
you may end up with a $1300 set of tires you can't use

I read online about someone trying and Tirerack told them no.

Tirerack can't even handle 245 V710s on an 8" wheel, I sat down there for four hours on route to the Oscoda Pro, the mounter looked completely clueless, then when I got to the event he had gouged out the silicone bead on my 3 pc wheels, one wouldn't hold air and two others had persistant leaks
never again ...
