20" wheels fit up front on s10 swap 53?

[sdvratrod]

i have a 53 3100 on a s10 frame, i am looking at the boss 338 wheels and ive seen alot of ppl do the 18x8 up front and the 20x10 in rear, my question is can i run a 20x8 up front without alot of clearance issues? the truck is mounted 2" off the s10 frame. i am going to run the 20x10 in rear.

[05snopro440]

What is the offset of those 20x8 wheels? I'm sure it's possible, if they're a decent offset. How much is the frame lowered? It's a custom application so you're best off to do the measuring yourself to be absolutely sure.

[sdvratrod]

looked on the website and i was wrong they are 20x8.5 and they show 2 diff offset in my bolt pattern one being
28 offset and 5.79 backspacing
and the other
14 offset and 5.24 backspacing

frame is on stock s10 suspension, no lowering blocks or coils yet. the body is mounted low on the frame making the truck sit with a lowered look. i was going to wait till i get the wheels/tires on the make suspension adjustments to get the right stance

My 48 truck uses a modified G-body frame which is very simular to an S-10. Mine is bagged and I'm running 20x8.5 rims with 6" of BS. My front tire size is 245 x 45 x 20. I can't turn lock to lock but other than that I dont have any real issues. I should mention that I'm also running inner fenders which helps to limit me turning lock to lock.

That's a sweet truck.

The track width of the G-body is at least 4" wider than that of the S-10, depending on the model of G-body, so you'll need wheels with at least 2" less backspace to get the same type of look.

My 8" wide wheels on the front of my '46 on an S-10 frame needed to have 3.5" backspace to clear the control arms and properly fill out the fenders. With 20's you might be able to get a little more backspace, but not by much without contacting the frame or inner fenders while turning. Without having lowered your truck it's impossible to say for sure what will fit. You need to measure yourself and see.

Yeah I should have been more specific. While a lot of the parts are simular between the two the track width is different.

Thanks for clarifying.

i will try to do some measuring and see how it looks, but with the s10 track width being narrow, i should look more for clearance on the frame or inner fenders more than the outer fenderwells correct? i would also prob try running like a 245/35/20 tire up front on them

[05snopro440]

You'll probably be more concerned with that, yes. I can go lock to lock on my '46 without rubbing, even while turning (when the suspension is compressed). Put a 15" wheel on and see how much room you have and where the tightest points are. Extrapolate from there in both tire size and wheel width to determine the offset you might need, and where your potential rubbing spots are.

I always preferred the deep dish look you can get with small backspacing when running an S-10 frame on these trucks. If you want to run the wheel specs you listed above, you'll need to run billet spacers to get your wheels out away from the frame and suspension. 3.5" Backspace was the absolute most I could run with a 15x8" wheel on my truck, and you'll want to run somewhere around there to fill out the fenders anyways.

[05snopro440]

I always try to get the truck sitting where I want it with a comparable sized tire (in height) to what I plan on, then I worry about finding wheels that will fit.

[sdvratrod]

i do like the deep dish look on the rear and a matching rim size better than the 18/20 combo alot of ppl run.

youngrodder what wheels are you running? they look killer

Thanks they are US Mags..

[sdvratrod]

what size tires and rims you running for your rear?

[youngrodder]

20 x 10 with 4" of backspacing. I also have mini 2 3/4" tubs in the inside of the bed. Rear tire size of 275 x 45 x 20

that is a sick machine sir !!! v v nice !!!!!!!!!!

I'd say that SDvratrod nailed the wheel/tire combo thing on an early truck. That truck has the perfect amount of sidewall showing on the tire and the wheels and tires work perfectly with the rest of the truck and don't overpower it or look out of place on it.

Youngrodder's truck is probably the most "right on the money" of any AD truck with big oversize wheels and low profile tires as they blend perfectly in with the rest of the package and don't look like an add for gaudy billet wheels like some trucks do where the truck serves as a background for flashy billet wheels. That is something to put a lot of thought into if you are going to the big rims and low profile tires as too many guys get it all wrong and go for the gaudy rims that the tire stores like to push.

Thanks guys....

I will tell to you that the wheels and tires were the last thing that I purchased. With my build taking close to 11 yrs this is saying something. I struggled with pulling the trigger on the "right" set of wheels.

Around this area far too many vehicles of all sorts look like the owner either went to the local tire store and said give me the biggest gaudiest ones you have in stock or give me the cheapest ones you have this size or bit off on what the kid at the tire store said was the hot lick wheel that week.

Back in the early 90's when I bought the Enkie 32's for my 48 we hunted for months for wheels that looked right and found them on display at the Portland Roadster show and ordered them the next Monday and they were the first wheels of that design ordered in the tire store I deal with. This time around the truck gets modified hubcaps and whitewalls as I am shooting for a build that possibly could have been done in the late 50's by a custom or body shop owner who wanted a custom truck.

Bringing this one back to life. Recently purchased a 1948 that is a work in progress but already s10 swapped. First on my list is tire/wheel combo (I'm liking the boss 338 and size choice as well) and suspension changes to get the stance I want as it's already running/driving.
Sdv did you end up going with 20x8.5 and 20x10 combo? If so any fitment or clearance issues? Also what offset/back spacing/wheel spacers did you go with?
Thanks!

Anyone have any input? May have to make my own thread, but was hoping to get some info here since its a very similar situation.
Thanks guys

this is a very difficult question to answer. basically every ones setup is different so any answer would be bad info. I searched the web calculators and did not find them useful. The only valuable info I found was the hole spacing and the original offset. For me, my original wheel width was 7.5" wide with a 40mm reverse offset. I could not use that offset if I wanted to go to a wheel 8.5" wide because the wheel would stick out 1" further..... I needed a 50mm reverse offset, which I could not find. Also, how low your fender sits off the ground will dictate how much clearance you have with any wheel when you go to turn. A lot of the really low trucks cant turn the front wheels without rubbing the fenders (they have to air them up to turn). Mine is a static drop so I had to keep the wheels in further.

Yep, in addition the fenders on one 60 year old truck could be a bit different shape from another or could be mis-shaped from years of use, so it's best to make sure the wheels fit your truck. Measure, measure, measure.

Im mocking up 22x10 rear 20x8 fronts.. IMO my fronts fit perfect. Had to pull the inner fender wells and going to need to build new ones.
