Wheel backspace for 69C10 6 lug - The 1947 - Present Chevrolet & GMC Truck Message Board Network

scotts72heavyhalf · 03-25-2015, 03:39 PM

Well its time to order a new set of wheels for the 69, I`m staying 6 lug and going with a 20" rear and 18" front for the staggered look, I believe the correct back space is 5.5 for the rear and I`m not sure of the front can you guys remember those back spacing numbers? I`m running a 5/7 static drop and thinking of going with H.R.B.B. Torque thrust style or Coys but the Coys are months from being available.

Thanks

Backspacing is directly related to wheel width.
I assume by staggered you mean 10" wide in the back and 8" or 8.5" wide in the front.
Also the rearend width will also dictate what backspace you need.
Which rearend?
67-69?
70? (two different widths available that year)
71-72?
Any plans to bag it in the future?
It aslo depends on how much you like the wheels to tuck inside the fenders.
I personally HATE when the front track width is wider than the rear.
SO I tuck the front wheels inside the fenders a little more than most,... to hide the fact that these trucks came from the factory with a wider front track width.

Yes, 20x10" in the rear and 18x8.5 in the front, I`m running the stock 69 rear-end housing with the 6 lug and 307 Eaton posi.

Thanks

Look at 72BlckButy's thread.
We measured 20x10 (4.75" BS) with the early 6-lug rearend.
And 20x8.5 (5.5" BS)
I would seriously consider going 20's all the way around.
255/40 and 295/40 Toyo Proxes tires.

One more.
These are 20" 6-lug Billet Specialties Vintecs ordered special.
My opinion only,... 18's look too small on the front.

**lolife99** · 03-25-2015, 07:48 PM

20x10 (with a 5.5" BS) works better when using the WIDER 71-72 rearend housing and on a fleetside bed.
Stepside beds take a totally different set of numbers.

scotts72heavyhalf · 03-25-2015, 08:59 PM

I was thinking that the 18`s might give me a little more room with tight turns and big bumps, I`m running 20`s all the way around now

**lolife99** · 03-25-2015, 09:29 PM

Wheel backspacing and overall tire height is the key to turning up front.

scotts72heavyhalf · 03-25-2015, 09:53 PM

Thanks Keith mabye that's the answer then the PO put these on and I don't think that was considered by him

scotts72heavyhalf · 03-25-2015, 09:55 PM

I'm looking at these

**lolife99** · 03-25-2015, 10:05 PM

Nice wheels.
But even the most expensive wheels don't look good if they don't tuck or tuck way too much.
That's why I always measure before I order.
There's tons of info on measuring wheel backspacing.
I wish you were closer, I would be glad to help.

Who makes those Scott? That's a good looking wheel

scotts72heavyhalf · 03-25-2015, 10:24 PM

That's a H.R.B.B custom wheel I have the download info for measuring and I will do that for sure

rwade · 03-25-2015, 10:38 PM

Never heard of them, I'll have to check them out. Are they expensive? Can you get custom offsets?

Thanks for all the great info and help Keith, I will measure twice before I order and go with your recomendation of the 20`s all around.
