Have I miscalculated this? |
It does look like the Proxes are all season...I have removed the Note under the specs.
I've never tried to figure out revs per mile or OD.
I got the OD from the GY site. I think that GY originally stated the OD was 27"...but I have seen posts where someone went out and measured the tires and they were closer to 28" in the front...so I'd go with 28.1" OD for front tire and then figure out your rp mile from that.
