Will this wheel fit on my truck? It is an 18x9 with 5" backspacing

click the image for specs...

What size tire do I need without having rubbing issues?

I need to be absolutley curtain these will fit and that I order the right tires before I make my purchase. Otherwise it would be a VERY COSTLY mistake!

Thanks guys!

Use this site as a guide: http://www.miata.net/garage/tirecalc.html

The front is important. The front will rub the fender before the rear. Are front and rear tires going to be the same size?

I think that my front and rear tires will be the same. I would like to have 8" wheels in the front and 10" wheels in the back but I can't find them in this particular wheel with the right bolt pattern.

Also... Thanks for the chart but the diamater of the tires I have now are going to be way smaller than the 18s. So I dont have anything to really configure with the chart.

adding bigger tires affects gas milage. Speedo is off, your Odometer is off too so think about gear ratio for your gas milage to

Yeah I dont think I'm realy concerned about gas mileage at this point. I'll be running premium gas with a 10:1 sb400.

Does anyone know if these wheels will fit?

Suspension http://67-72chevytrucks.com/vboard/f...splay.php?f=25 may get an answer there but what i was referring to tire size and gear ratio need to be considered along with the tranny just something to think about

The wheels will fit. Your problem is how much tire do you want? Rubber bands or some sidewall. The link above will help you determine size based on actual truck measurements.
