18 vs 15 inch wheel set ups

Looking for some insight as I have a 94 RMW that I need a new wheel set up for. Currently it has a 235/65/16 and 255/65/16 combo. I was looking at a squared set up of either 255/45/18 or a 255/60/15. Both get me to a 27 inch tall tire. Anyone running either set up? Any thoughts? I was looking to go 285/40/18 but the tire selection and price is a bit out of my comfort zone.  Thanks

I currently have 255/60 on 15x8 wheels. Car is dropped on springs and I am currently installing air ride.





Recently acquired a set of Impala SS wheels with 255/50 17 which are also 27" tall.

Good webpage for checking tire height/width. https://tiresize.com/height-chart/

That is exactly what I was looking for. What spring set up are you on? What wheels are those? I am trying to hop up dads wagon but keep it in the same style he wanted.

Thanks again....

Moog 5662 in front. Moog cc501 in rear. Wheels are the star wheels from Jegs.

Please excuse the noob questions but are those springs for lowering the car?

Thanks

They aren't specifically for lowering the car (front are for 80s F body and rear are for 70s A Body cars) but they are used by many people to lower these wagons because they are cheaper than lowering springs. When I got them they were about 100 bucks for all four. Prices have substantially increased for everything on the planet since then.
