nooob question (backspacing)

[Dishtowel]

I feel silly asking this
Yes I searched, I still didn't learn what I wanted.

Which rim will stick out wider from the truck? One with 3" backspacing or one with 5" backspacing??

I want the rim OUT and WIDE for my new rubber. I know this will consume wheel bearings, I'm ok with that.

This should help you - backspacing is the distance from the inside edge of the rim, to the mounting surface. A rims backspacing is also closely related to the offset, which is the distance from the rims centerline to the mounting surface.

Now you figure it out.

ummm..
thanks?

Deep down somewhere I knew that, BUT I have read conflicting information.

What you have said Brendank (if i'm reading it right.... duuuuhhhhh?) is that a SMALLER backspace value will give me a wider track/stance.

Yes, the smaller the value the more the wheel will stick out, assuming the new wheels are the same width as the old ones.

I'd suggest finding out the offset of the new and the old wheels, and then plugging the values into this calculator.

Thanks man, but that calculator is more for the street/showy rim guys. where there rim envelops their brakes and stuff. IDK if thats what i'm looking for.

Right now i'm running stock rims and 32" rubber. The rear of my tire hits my radius arm before my steering reaches full lock. This will obviously get worse with larger tires. I want to run 35's when the opportunity arises. WIDE 35's. I am planning on a 10" wide rim with as much (as little? i guess...?) offset as I can manage.

The calculator isn't more for one type of vehicle than it is for any other. It figures out distances in relation to what setup you previously had. Nothing about it has anything to do with any specific type of truck or car. It's a good tool to get an idea of where you'll be at. When you change tire diameters and rims at the same time, nothing beats whipping out the good ol' tape measure and checking for yourself.


I went from a set of 33's on stock rims to a set of 35's on 15x10's with -38mm offset. With the stock rims, it rubbed pretty bad. Once I put the 15x10's on, the rubbing was completely gone, and the tires stuck probably 2" out past the stock fender flares.
