BFG R1 VS Hoosier R7
#4
I haven't run the R1 since spring 2013, with a brand new set that I ordered which was date stamped as manufactured in 2011...gave me old stock! Has the compound changed since then?
Regardless, I ran both the R1 and the A6 that weekend. I ran a nominally better time on Friday with the R1 than I did on Sat/Sun with the A6. But, it was a good 15 degrees cooler out on Friday, if I recall.
I remember the R1 feeling more like a real race tire than the Hoosier. Less compliance, and had to drive them more precisely. Also interesting to note that I had a significantly higher top speed with the R1, so perhaps it had less rolling resistance?

I would have bought another set and continued testing the R1 as it showed potential. But BFG doesn't offer any contingency for NASA Time Trials, only W2W. So, frankly, I wasn't interested. Somebody at BFG needs to get their head on straight and realize all the business they are losing. I am far from the only person who won't buy their tires for this reason...

I've talked to multiple BFG engineers and commercial people about this...I've always gotten the same/similar response. "We're looking into it"... They're aware of the market for 225/45 but apparently the numbers haven't made sense for them.
My understanding is they don't have a mold for the R1 in that size and that can't adopt the 205 mold to work. Paying for a new mold makes the business case a lot more difficult. Last time I asked about this was either 2012 or 2013 so who knows what's changed between then and now...

I've read from racers that the 205 A6 is faster on a 9" wheel vs an 8, so assume a 225 is better on a 10 than 9. Does that mean the 245 is slower on a 10 than the 225? Savington says the R1S is faster than A6 Hoosier, but again, what about 225 (largest r1s) vs 245 A (A7 now)?
I'm guessing that the 245 A7 on a 10 is faster than a 225/50 R1S on either a 9 or a 10...

I see a 225/50/15 available now: http://www.tirerack.com/tires/tires....FR1S&tab=Sizes

So the 245 A7 and its 10.0" section width is the best solution on a 10" wheel? Too much friction slowing down straightaway and corner exit speeds?
