A local buddy that I dice around with found the 245 on a 9 to be ~1s faster than the 225 on the same 9 for both Buttonwillow and Laguna Seca at ~130whp. Could be conditions, could be real, but he has run them on 9s for quite awhile before trying the 245. I spent the few hundred bucks to run them on 10s and seems to be fast, so I can't and won't complain although I'm told that 225s on 9s would be faster.

i found this today. This is how a race tire should look. this is a 245 on a 9". i'm not a fan of stretching race tires for road courses. i'll pick a 225 on a 8 every time. it feels like the sidewall is actually doing it's job. allowing for maximum traction. for auto cross i'll run a 225 on a 9". i like the turn in feel it gives.

There are a few narrower p1 (prototype 1) 245/40/15 RC-1's floating around with 2014 DOT codes and should not be confused with current production. Maxxis had a bunch left over after the first test and wanted to get rid of them. I bought all 50ish tires and sold them off to team members and selected Club Orange customers. By looking that pic, it's possible its a P1 tire.
This is a production 245 on a 10.

There is just about zero chance you or anyone else on the planet has a prototype Maxxis anything without knowing it.

This isn't inherent to 245s. 225s and even a wide 205/50 (Hoosier) will produce those same marks with adequate camber. IOW, if you don't see those marks on your shock tower, you drive like a pansy

After reading this thread I did some research on Tire Rack. Something I think some people have missed is that section width of a tire IS NOT equal to the tread width of the tire. Just looking at the specs on Tire rack, most 205/50/15 tires have a smaller tread width than section width.
205/50/15 Toyo RA1-8.4 inch section width/8 inch tread width
205/50/15 Potenza RE-71R-8.4 inch section width/7 inch tread width
205/50/15 Dunlop Z2-8.4 inch section width/7.5 inch tread width
Point is that saying that a 205 50 15 on an 8 inch wheel is always best is only part of the story.

The only 205's that might not be fastest on 8's (other than Hoosiers) are low performance street tires that are much narrower than 205mm tread. For those types of tires, no one cares about max g anyways. We're sort of assuming <240tw, DOT R compound or full slicks with a stated "205" tread. In which case theses 205's will be significantly wider than say, an 400AB Nankang Highway Grand Master Supreme XT, and thus, fastest on 8's.

In addition, using those examples above, all 3 have an 8.4" section width. It seems to me that the section width is what will determine how it behaves on a particular wheel width more than the tread width.
I would wager that each of the tires listed would perform better on an 8 than on a 7" wheel.
