my current setup

18x9 rpm r-505 painted black 24lbs each
275/40 rear
245/40 front

looking at getting
17x9 5 Zigen black fn01rc's 17 lbs each
I was told that I could get all they way to a 315 tire on the back.

This z is now going to be used for weekend cruizing/drag/autocross. I am not worried about the style of the rim as much as the performance for both drag and autocross.

what do you guys recommend for tire sizes?

 

the guy at the shop im working with is suggesting 275 up front and 315 in the rear. will that be too heavy and or big for 17x9 rims? remember I am looking for performance

 

You should post this in the racing forum, you will get more informative responses.

 

thanks posted

 

I responded to your other thread, but 315 is too large for 9 or 9.5. 275 can be done in the front with some planning. You don't want that for dragging though. I highly suggest your "everyday" set be for autox and you get a cheapo set of rears or use stockers with 255s for drag racing.

 

If your looking for 17x9's you should check out these threads:

If you are happy with a 275 mm tire on a 9.0 inch wheel leave it alone.

 

you can get those wheels in a 17x10 for the rear.
