TheNick Posted December 10, 2008 Share Posted December 10, 2008 Yup they added a section to the middle of the 245/35/18 mold. Should be interesting for the RX8's in BS and a couple Porsche's in SS. Thats a pretty short tire - I bet it would work nicely in the front of a Z Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 10, 2008 Share Posted December 10, 2008 Looks tall to me... Quote Link to comment Share on other sites More sharing options...
TheNick Posted December 10, 2008 Share Posted December 10, 2008 Its right on par with a 285/30/18 and when it comes to autox thats a short tire. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 10, 2008 Share Posted December 10, 2008 I deg to biffer Here is a short tire on an autox Z: That is a 23" tall tire on a 13 x 13 rim. The front tires that go with it are 20" tall. The 15 x 11.5" x 23.5" FA slicks I'm going to run are also quite a bit shorter than the 18 in question. For an 18 its a short tire, I'll agree with you there. I'm still convinced that an 18 isn't the way to go, especially on an S30. Quote Link to comment Share on other sites More sharing options...
TheNick Posted December 10, 2008 Share Posted December 10, 2008 Agreed - but you are talking slicks - not DOT tires. If I was running a Z in BSP or SM2 I'd be seriously looking at this tire. Ok probably not - I'd be on a 275 15" front and a 315 or 305 17/18" rear in BSP and a 275 rear in SM2. Quote Link to comment Share on other sites More sharing options...
johnc Posted December 10, 2008 Author Share Posted December 10, 2008 Its a bit tall for an autocross tire on an S30 but it would work as a track tire. I ran 25.2" tall tires on the ROD and, although some compromises were required, it worked well. If the rules allow suspension mounting point relocation then tire OD is less of an issue.
