wheel/ tire size with 4/6 drop - The 1947 - Present Chevrolet & GMC Truck Message Board Network

67Dad · 07-08-2010, 07:04 PM

Hey guys,

I should be ordering wheels/tires this week but I'm still not exactly sure about the tires. The wheels will be AR Torq Thrust II's 17x8 all around and the truck will have a 4/6 drop. I'm either looking at getting 275/60-17, 255/60/17 or 275/55/17, 255/55/17 or something similar. Does anyone know what they think would be the best, or your own ideas? Also, pictures of similar setups with the wheel/tire info would be great.

Thanks!

Got a 4/6 drop on a 70. Running 255/50 17 BFG TA KDWS on 17*8s. There the original size on the 94-96 Impala. Good compromise between ride and handling.Ride almost as good as my old 275/60 15s

I will be shooting for around a 29" tire in the front and 30" tire in the rear.

I believe stock is 28" and imho its just not enough tire on a truck.

Yeah with the 275/60 and 255/60 it would put it at 30 and 29. I believe it would fill in nicely with the drop.

If you check on the bfg website you can get info about rolling diameter. Other tire sites may have the same info. Those 275s should look pretty meaty in the back

That's the look I'm going for!

here's a cite that someone gave me to help out with all the sizing:

Nate - what are the rim widths on your 20's?

72BlckButy · 07-10-2010, 01:52 PM

Zoomin the wheel/tire info for the 20's are as follows:

Billet Specialties Vintec's
Front: 20x8.5" w/ 5.5" BS
- Center Bore: 3.430
- Bolt Pattern: 6 on 5.5"
Rear: 20x10" w/ 4.75" BS
- Center Bore: 4.250 (due to the center hub on the rear axle of my '69 [meas. 3.5"; BS only offered 3.43])
- Bolt Pattern: 6 on 5.5"

Toyo Proxes S/T ii's
Front: 255/40-20
Rear: 295/40-20

I am running 17x8 in the front with 255/50/17 tires and 17x9.5 with 275/50/17 tires in the rear. Here are a couple of pics:

67Dad · 07-11-2010, 04:22 PM

Yalls trucks look great! The comparisons really help with what I'm getting. Does anyone know how well a 275 fits on an 8" wheel?

**Boog** · 07-11-2010, 05:03 PM

275/60's are perfect on an 8" rim.

Yes, the front wheels on my truck have 4" of back spacing.

It is close...the top picture is 3.5/6", the bottom picture is 3.5/5". As soon as the truck is back out of the garage, I will take better pictures.

Were those sizes in your sig the whole time? No matter, I love looking at your truck.

72BlckButy · 07-11-2010, 10:28 PM

Yep... but that's no biggie.

Bigg G · 07-11-2010, 10:46 PM

Nice wheel choice for a classic look but make sure you get the correct back spacing to make the tires tuck. I had TT2's w/ BFG 255-55-17's on my Silvy last year but had to sell the set because they didn't have enough back spacing to tuck like I wanted them to.
I'm thinking the older trucks have more fender space so you might be good with 5.25"-6" of backspacing.

Yeah I think I want to go with 255-55-17 in the front with 275 in the rear. And I've figured out that 4" of bs would be good all around for 17x8s...can anyone else say the same?
