I cant make up my mind on what to get on my 2020 ram 2500 mega cab. I plan on running 35". I had my heart set on fuel coverts .
I've even paid for them and the tires. I told the sales guy to let me sleep on the offset. I have a carli 2.5 leveling kit. What is gonna be
the most aesthetic looking offset?
 
Will you be running flares? If so the +1 would be good if not it will look silly
 
+27mm with 35's

Keep in mind that offset is wheel width dependent. +18 will get you right out there near flush with a 8.5" wide wheel. 10" wheel is gonna be completely different.
 
And, to compare, here is 295/70R18 Falken Wildpeak on 18x9 and +20 offset.

This should give a good comparison - my tires are about 12" wide, and the 325/65R18's that @andy posted are about 13" wide... so split the difference for 35x12.5's

this is not true, your wheel offset will determine the placement of your tire to the fender regardless of the wheel width. Backspacing on the other hand would effect tire placement differently depending on wheel width. Remember offset is the measurement of the wheel’s mounting surface to the dead centerline of the wheel, so regardless of wheel width, the offset from the center is the same and that determines the ultimate positioning of the tire. For example if you mount a 12 inch wide tire on an 8 inch rim or a 10 inch rim the width of the tire tread is the same, and the positioning of the center of the tire is direct with the center of the wheel and that center point, regardless of width, is ultimately determined by the offset.

I think you may be mistaken.... Lets use a 0 offset wheel for an example so mounting flange is dead center so on an 8inch wheel thats 4” per side of center line on a 10” wheel thats 5” per side of center line resulting in one inch sticking out per side more than the 8” wheel would provide so to have the wheel stay the same distance outside of the fender as the 8” 0 offset wheel (4.5” back spacing) when going to a 10” wheel you would go +25 offset (6.48” BS)

If your tire width is the same, no difference. Use any of the numerous on-line calculators, then you’ll understand. Your math is right, and your idea makes sense as far as where wheel lip sits to the fender, but your tires being wider than the wheel makes the offset the only determinant that matters. Now if you are running skinnier tires than your wheels then you have a point, but who does that?

I get what your saying now sorry i was only talking wheels. Width of the wheels will affect the tire width slightly but you are correct i see lots of stretched tires so we go by wheel width here im not in to that but lots of people are for some reason

Yes, the wheel will be out further but not the tire. It will look different regardless. I had a spare for my old Jeepster that had a 10" wheel with the same offset as my 8" wheels. When I put that spare tire on it was completely obvious it was different. The tires were 33x12.50x15s but it made the spare looked wider than the other tires. I never measured it and I only ran the way for a short time, but dang did it look weird.
