Hello All. I am new to the site. I just ordered 18x8.5 front wheels and 18x9.5 rear wheels. What is the biggest size tires I can put under the fenders. Stock Rearend, no tubs, no fender rolling? Anything you can help me with would be great.

I would prefer a street radial, aggressive tire. No Drag Radials. Something that looks well proportioned.

What backspacing did you request on those wheels? As for tire sizes,a 255 or 265 would be the widest I would run on a 18x8.5 wheel and a 285 on a 18x9.5. Any idea as to what aspect ratios you want to run on your tires?

I ordered a 4.25 front and a 4.75 in the rear. I have to see how they fit when they come here so I can either add a spacer or leave it.

I guess with that size rim wouldnt it be somewhere around 45% or so. I guess I would be somewhere around 255 45 18 for the front and 285 55 18 for the rear. What would you suggest?

You probably should have closer to 5.5" backspace on your rear wheels to allow for extra clearence on the outer fender lip. You have a lot of room to the inside you can use an be able to run a wider tire like a 295-45 on the rear which would go well with the 255-45 on the front@

If you can still cancel those wheels,I would. You need at least 4.75" backspace on a 18x8.5 front and 5.25" backspace on a 18x9.5 rear wheel. 5" on the fronts and 5.5" on the rears will work,too.
