    I am looking to try out the R1-S this season and it appears that the specs on various vendors are not consistent with the BFG official website. The size I am looking at is 285/30/18.

    BFG website: http://www.bfgoodrichtires.com/tire...spec_table

    Part #: 05904

    Wheel width range: 9.5"-10.5"

    TireRack (or various other vendors) website: http://www.tirerack.com/tires/tires...Force+R1-S

    Wheel width range: 10"-11"

    So a couple of observations/comments:

    1) According to BFG website, it appears that for the same size 285/30/18, the minimum wheel width is different between the R1-S and R1.

    2) Seems like all the vendors are showing the incorrect specs for the R1-S if it is indeed true that the same size has different minimum wheel width requirement

    3) Are the R1-S really wider than other brands for the same size (i.e. if I ran V710 in 285, I should run 275 for the R1-S)?

    I have emailed BFG about it, but they didn't really answer my question on why TireRack is showing different specs than their website.

    Just want to hear your opinions/experience.

    Thanks.

    We have been running the r1-s in our BSP S2000 for almost a year. They definitely run wider than hoosier and kumho. We started with 275/40/17 on 17x10 last year and compared to a 275/40/17 a6 they were considerably larger. We made the switch to 18x11 using 275/35/18 for this season. When discussed with bfg we were advised that the 285/30/18 was large and would not fit on a e46 3 series and that the evo guys were also running the 275/35/18. Due to the gearing we choose the 275/35/18. They are large and required aggresive fender work to clear the s2000 fenders. They are slightly stretched on a 11" wide wheel and would probably be square on a 10" wheel.

    Thanks.

    Did you measure how much wider? So I am guessing a 275 R1-S is equivalent to 285 V710 on the same wheel?

    Tire Rack no longer lists the R1-S? Anyone know what's going on?

    Checked their site today and seems fine.

    Yes the BFG R1s run on the large side. I am trying the 285-30-18 on the rear of my car. The 285 is 11.4 inches wide across the tread surface mounted on an 11" wide wheel.
