Well, I am running 3.73's in my rear now so I will need to step up to a 28" tire or else I will run out of gear. I just need people's $.02 on what tire I should run. For the street I already have a set of 275-50-15's on my 15x8 draglites. That is basically the widest tire I can put on because of my 3" tail pipes. So, should I go with a 275-60-15 drag radial or a 28x10.5 ET Street. Keep in mind I run a stick car. No idea on launch RPM yet. It will also be mounted on a 15x8, for now anyway.
