I respect your opinion, but I hate you and you’re wrong.

 

Sometimes you stop to rephrase something and then you're like nah.

Randall has hurt my feelings.

 

Wider wheel and Seems like less backspacing. Hopefully you won’t have any issues with your fitment up front.

 

Same amount of backspacing, 3.5”. I’ll clear my suspension up front just fine but I’ll definitely rub the firewall and cab mount now.

 

Randall is bae.....

 

Randall is the child of Lucifer!!

 

Does a wider wheel with the same BS as a narrower wheel have less offset? Or do I have that backwards?

I was referring to the firewall / cab mount, I’m sure there was absolutely no issue with suspension clearance on those wheels.

 

edit: a 7.5” wheel with 3.5” BS has a -18mm offset and a 9” wheel with 3.5” BS has a -36mm offset.

 

I don’t pay much attention to offset. What I care about is backspacing and width. BS is a static measurement that’s applicable across all wheels of different shapes and sizes.

I hate when people say “I have a 0 offset wheel.” Well ok, that doesn’t really mean anything. 0 offset is worlds different on a 7” wide wheel vs a 10” wide wheel.

 

Well offset doesn't pay much attention to you!

 

Offset = Dave

 

Rear two tires are finally done, coming in right at 4 hours. You can easier see the size difference now between the two tires.

 

I agree with what you are saying about the offset being an incorrect “go-to” number for wheel spec, but they do need to be used together. Correct me if I’m wrong though, because I honestly don’t know a whole lot about wheels and probably am. This is just my lack of knowledge here trying to verbalize a thought.

A 9” wide wheel with 3.5” backspacing and a 7.5” wide wheel with 3.5” backspacing are not the same, and that’s where the offset comes into play. The offset is the independent variable to the backspacing measurement. The 9” wheel has 5.5” of wheel past the mounting surface where the 7.5” wheel has 4” of wheel past the mounting surface. The wheel with less offset (9” wheel in this case) sticks out further from the hub and therefore has a greater scrub radius than the wheel with greater offset (7.5” wheel). And as far as fitting a tire in a wheel well, the scrub radius is one of the main things that matters.

That being said, the same conclusion is drawn from BS and width. I think we are saying the same thing in a different way, but you know more of what you are talking about. Haha.

 

crazy how much difference it makes. The geolanders measure on then tall side too.

 

Pretty certain it will all be explained soon.

 

You’re correct that a 7.5” and 9” wheel with 3.5” backspacing aren’t the same, but you don’t need to know the offset to know that. All you need is wheel width and backspacing. Just those two numbers and you can determine how much poke you’ll have and all the other stuff you mentioned. Offset is really only good for calculating backspacing.

a 30” wide wheel with 0 offset compared to a 2” wide wheel with 0 offset. Offset is the same, but scrub radius is obviously very different.


Now if you had a 30” wheel with 15” BS and a 2” wheel with 1” bs, you still know how much wheel is going to be sticking past the hub.

Hopefully that rambling makes sense. There’s more than one way to skin a cat, but I prefer using backspacing because it’s static across all wheels.

 

I see what you are saying now. Much easier approach. I just try to over complicate everything, lol.

I also have wheel envy
