R compound tire test in GRM
 

just got the new grassroots magazine.
they tested the BFG r1 vs. kumho v710 vs. hoosier a6 vs r888 (the toyo ra1 replacement).
it was perfect test for me because they tried to use 285/30/18's which is what i want to run next season.
weird thing is they used stock rx8 wheels size of 18x 8.
i used to wonder if the hoosier would fit on my 9.5.....well they put it on an 8 inch wheel!!!
so i guess the hoosier would fit mine (tire rack specs says min for hoosier is 10.5 wheel).
then they put the v710 on and it didn't fit! Too wide. so they used a 245/35/18 instead.
they used a 295/30 for the R888.
v710 had the fastest 10 lap average and the fastest overall lap.
a6 second place. R1 3rd and R888 4th.

thats F'ed up comparing different width tires.
bleh

So the v710 used the appropriate 245 width on an 8 inch wide rim, and all the other tires were waaaay too wide for that rim. I'm not surprised the v710 cleaned up. Doesnt seem like a valid test at all......

Yea, I wonder how much of that is down to the 710 being a superior compound (debatable, but it has been shown fastest before) and how much is down to it being the appropriate size choice?

i think they also tested lateral g forces and hoosier had the highest peak reading.
i think the reason the kumho won is because it was a smaller height tire which added the torque-less RX8; the smaller tire (height-wise is the same as a change in gearing).
obviously a flawed test but it did have good intensions :)

Woulda liked to see the NT-01 in there.

i think they did NT-01 in previous month. i'll check when i get home tonight.

the R1 finished up top last month

the NT-01 and the R6 finished tied I believe

and some other tire finished fourth.
