Guest SpudZ Posted July 13, 2002 Share Posted July 13, 2002 Hey guys , I have my 225/45/15 Hooisers mounted on my 15 x 8's and am wondering what a good starting point would be on tire pressures. fronts and rears. The event is on a road course and they throw a few cones in to keep the speeds down. Thanks for any help, Mike Quote Link to comment Share on other sites More sharing options...
Dan Baldwin Posted July 16, 2002 Share Posted July 16, 2002 Check your hot pressures. Hoosier recommends 41 - 43 psi hot, IIRC. This can give you a clue to your setup as well. I normally run 35 cold, but noticed at WGI that the fronts were only getting to 40-41 psi, while the rears were getting to 44-45. I adjusted pressures accordingly, but the message is I'm working the rears harder than the fronts. Quote Link to comment Share on other sites More sharing options...

Guest SpudZ Posted July 16, 2002 Share Posted July 16, 2002 Hey Guys, I started with 38 front 35 rear and marked the sidewalls, since the tires were road race take offs I needed to scrub all the crap they leaft on them. Plus they were running them on 15 x 7's and they had alot of roll over on the outside edge. I eventually went down to 33 front and 25 rear , but that seemed to be way to much. they felt good around 35 front 30 rear or so. I just started to roll the tires a bit on the last set up. Each run I made was faster as I built up confidence on the tires grip. I still have a major camber problem on the drivers front. It is either due to a extremelly worn control arm bushing or a bent strut. Both front strut inserts are shot. I had lower times then my normal competitor until the final run. It is a well sorted Jag XKE with an experienced driver. He ended up beating me by 1 second on a 1:10 course. My last run was a flyer until I blew by a gate. I should have hit that stinking cone and got the 2 second penalty instead of the 10. I did beat a BMW M3 though Our class winner was Duke Langley in his National caliber Corvette. He was over 10 seconds ahead of me. Quote Link to comment Share on other sites More sharing options...
