285-40-18, on an 8" rim...

I have heard of people running 275's on 8" rims, and that was pushing it, is 285 doable? I want the taller overall diameter, so that it matches the height of my front 255-45-18's. I'm thinking the increased sidewall might allow it? Whatcha think?

I'm sure it can be made to fit, but how it handles and wears are going to be a question mark until you try it. 8" is narrower than recommended for 275/40, people do it because their stock Mustang wheels are 8" wide, and they want to jam wider rear tires on. Sure, you'll have an extra 1/4" of sidewall height to flex, but you'll also have almost 1/2" extra of width to be fitting on.

Give it a go, and let us know how it works out for you!!

I'd really suggest getting at least 9" wheels for that much tire.

Ask Cudaz101, he sure knows his wheels. I bet he could give some clear insight for you.

Nah, I bug him too much. Even if it will fit, I think I'd be too worried about issues with the tire when actual driving. Wouldnt feel safe romping on the car. We're gonna say no on this one.
