Default 18x9.5 tire size question

I searched but couldn't find the exact info I needed. What tire sizes f/r on an 18x9.5 would be optimal for a 1-2" lowered SC400?

I'm thinking f/r 245/40 and 285/35 respectively???

Since I found out how cheap the sportmax line of wheels are I'm getting hungry for some wheels!!

Your fenders need to be rolled with a 285 either way.

Your rear sizing sounds about right, but wouldn't 255/40 be a little too tall?

Ya, 285 would be nice but theres that money factor!!

265 on a 18x9.5" wheel sits flush with the edge of the rim.

Would f/r: 245/45/18 and 275/40/18 be too big for an SC4?

yes, by an inch...

and those sizes you quoted are only going to fit on higher offsets... +35 or higher with rolled fenders...
