How much does tire width affect MPG?

I currently have a near brand new set of load range E, 235 width tires on my new-to-me OSB. I'd prefer to have a wider tire primarily for looks. I'd buy a second set of rims just for wider tires for the looks and a cushier ride if it makes sense.

My question is: How much do the wider tires affect MPG? Most of my current driving is city streets and FM roads, very little freeway miles. But, I have a 16 hour each way family road trip next month and am trying to justify a smother ride. But at what fuel cost penalty?

Thanks!!

I envy those that know exactly which modification to make and in the most logical of sequences. But not enough to trade for my meanderings and misfires.

235 tires ride great and I think it does make a difference in mpg and also initial purchase cost
