Yes great times can and have been run on a 17x8 wheel. But.... In theory, faster times should be doable with the 9 inch wheel. It's all about the shape of the contact patch that's on the road at any one point. I believe the data we use at work would probably support this also. 1 Link to comment Share on other sites More sharing options...

GUN-808 Member 251 Member For: 11y 17d Gender: Male Location: Gold Coast Posted 11/12/14 08:31 AM Share Posted 11/12/14 08:31 AM Totally agree,my 16x8s only just spread my 255/50/16 ET Streets,now way a 8" rim could make full use of the 275 tire.Guys with 3-400rwkw ish get away with it but when hunting that sub 1.5 60ft a wider contact patch will be needed.Every bald set of 275s on a BA 17x8 rim has some meat left on the shoulder from what I've seen.Exactly what im trying to say above.. The sidewalls will pull the shoulders downward and inward resulting in them NOT being used..Tire pressure will compensate for this possibly but its NOT the ideal combination..And as tyres "grow" it will bring the shoulder into play and there will be a loss in contact patch in the middle of the tyre..Spreading a tyre with complementing tyre pressures will ensure the best grip all round hence why its a common thing overseas with the small tyre big power boys.. and yeah id hardly call 60s in the 1.5s fast.. not saying its not decent but im pretty sure with the correct combo 60s would be better..im also going to say the 17x8 is a MUCH easier rim to come by and that's the main reason a lot of people have used them rather than them being the right rim for the job..
