Hey guys, I need some help figuring out the right size tires to put on these rims (c300 4matic). I'm thrown off because I expected them to be 8.5" and 9.5" respectively instead of 8" and 9".

Thanks!

On the 8.5" recommended width is 255
On the 9.5" recommended width is 275

So should I stick with that for the 8" and 9"?

I was thinking about going with 245/40-18 and 265/35-18 but I'm just confused as hell.

I would recommend 235-40-18 on your 18x8" but running 245's shouldn't be an issue. The 265-35-18 is perfect for the 18x9".

Your biggest factor is going to be your offset. The offset is what will make or break the look you're going for.

I appreciate your help! The offsets are coming 48mm and 50mm. I think I'm going to take your advice on the front tire size. I'd just like the wheels to look biggest.
