275 tires

[quote="whatbumper"]Sorry. Been trying to get ready for x275 race at Denton this weekend.   Have a couple of customers taking cars out.  How we set up cars the air pressure depends on multiple factors. On the old tire we run between 15-20 and the new tire its between 17-19.  I know that seems broad but every car is different.  What's your car weigh again?  I know you've cut a lot out.[/quote

3100 na bbf. No timing controller. Hits the tire hard.
