On a 19x8.5" wheel with a +50mm offset...what is the widest and the thinnest tire I can go?

This will be going on my coupe which I have +25mm spacers on....and lowered on 350Z Tein H Techs...

I need new tires and seeing what my options are...

Thanks!

 

Anywhere from a 225-255 is within the safe operating range recommended by the manufacturers. You could possibly go up to a 265, but I would go no wider

 

That's what I thought...I'm running 225 fronts and 255 rears right now...Just wanted to know if I could go a little wider on the back but oh well.

Thanks for the input!
