New guy here and need to be educated
Just got a 82 chevy step side and want to put possible 20"s all round and lowered 4|6 , does anyone have this rim setup on their stepside
I'm needing all info on the rims and tires that will fit.
Also are the tire , rim combo the same on step sides as fleet sides ???? as far as fender room ???
Any info would be great
Tires and rims is a lot of $$$$$ without getting it right.

Best advice I can give, is get some cardboard. Lots of it. Cut it to size of the rim tire combo you Wana run put it on your wheel studs n check how much clearance you have.

Welcome...
Rim dia is insignificant....the size of the tire (od & width) you want to run is what matters...along with back spacing and rim width

Thanks for your replies
I was hoping that some body on here would have a set up on their 82 step side that had 20's and give me all the details on tires and rims , backspacing , tire size ,

I had some on my 86, it was a fleetside though. I didn't like them, finally got rid of them and got 18's with more tire. Rides so much nicer now. If you do a search on wheels, you'll probably get quite a few threads on the subject.
Here's one, it has several trucks with 20's

Your opinion on the ride quality of 20" wheels & tires are subjective when you're comparing that 1 combo on that truck. What size tires were on those 20" wheels you previously used before swapping to the 18" set-up? What size tires are on the 18" set-up?

Wheel & tire combo's are based on individual preferences & budgets.

Research will suggest 20x8 - 8.5's up front will work w/o issue. Steppers are notorious for limited rear fenderwell clearance. I know some have squeezed 20x9.5's but they needed to really nail down back-spacing (BS).

So here's where preference & budget turn the discussion..... Some drops require rubber band sidewalls while others allow moderate. Some guys are obsessed w/the drop amount & opt to run 'whatever will fit' to be the lowest truck vs doing some sort of compromise that gets a nice drop w/some decent sidewall.

Then there's the entry price point 'on the shelf/in stock' CAST wheel choices that come w/limited BS options vs. billet aluminum wheels w/more specific BS options. More BS options allow better (more precise) placement which can lead to more tire size options.

Which category are you?

Thanks for schooling me Scoti and well put also
This is the reason I'm asking these questions , to figure out what my needs are and what will fit my step side . I do want the 20's and for price , I'm in the middle bracket for what I want to spend
Thanks again

Have you checked out the Billet Specialties 'Speedway' series wheels? They're a nice, middle price point wheel w/several BS options. The 20's are available in 8.5 & 10" widths & a BS range of 4.25 - 5.5".

The nice thing about steppers in my opinion is the ease of 'modding' for additional clearance in the rear if desired. Some measuring/trimming, some fleetside wheel tubs bolted in, & boom..... more room. There's more to it but it's do-able.

Stick w/a tire sidewall as close to or greater than 4" tall for better ride quality (a 245/40-20 would be as short as I would go up front). The taller the sidewall, the better the ride should be.

You mentioned a planned 4/6 drop (mild). Mild drops can handle a ~28" front/29-30" rear tire w/o much (any) issue. More drop or taller tire in front will start to yield clearance problems w/factory inner wheel wells.
