16” Tires on C20
 

Picked up a project truck. Replaced the missing carburetor and with a little time the 402 is running pretty dang good. Now I need to get some shoes that don’t look like they’ll explode just by looking at them. The truck has 235 85 R16 on it right now but I was thinking of going to a 265 75R 16 to fill out the wheel wells a little more. Looking for advice.

I'm very happy with the 265/75/16, as you say it fills out the wheel well nicely on a 3/4 ton.

I've got 285s on my 68 with an alum rim

Re: 16” Tires on C20
 

Your truck looks awesome! Did you mount them on the Chevy 6" rim or find a set of the f*rd 7" rims?


Any pictures of your truck with the 285s?

Re: 16” Tires on C20
 

You might check those eBay tires, I don’t think they are LT rated, just P rated. I’m sure they are offered both ways.

Thanks, I did try to find some used Ford rims, I lived in the Sacramento, CA area back then. All the local salvage yards only had junk rims, so I bought online from this company, 7x16.

Re: 16” Tires on C20
 

235 85 16 and 265 75 16 are virtually the same height just different width. Either is a good choice, but I prefer the wider tire look. If you plan on running a 6” rim I would stay with the 235 although lots of 265 installed on the 2000-2008 GM 6.5” rims. I ran 265 75 16 0n my ‘70 C2500 on Alcoa super single forged wheels and it looked fantastic. The math, if you are interested:

265 is the section width in millimeters. There are 25.4 mm per inch. 265/25.4= 10.43 inches wide. The profile is 75% of the section width: 10.43 x 75=7.825” sidewall height. Times two for the bottom of the tire and top of the tire = 15.64 inches high. Added to the 16” rim diameter you have a tire 31.64” tall and 10.43 inches wide.

235 85 16 tire is 9.25” section width and 31.72” tall.
245 75 16 is 9.64” wide and 30.4” tall
285 75 16 is 11.2” wide and 32.8” tall.

Re: 16” Tires on C20
 

All true, and a great explanation of what the tire sizes mean. If I may, I would like to add that the measurements can be somewhat nominal. There are sometimes slight variations in actual dimensions from one brand to another. This is usually insignificant unless someone is super particular about tire size or is mixing brands.

Re: 16” Tires on C20
 

Found these on craigslist. Seems like a good deal.

Can you run beauty rings and the stock dog dishes at the same time?

Re: 16” Tires on C20
 

Stock dog dish wont work on those no nips. They look like much later model years


Edit: They look just like the wheels that were on my 98 GMC Savanna van trim rings and center caps that were held in place with the plastic lig nut caps

Re: 16” Tires on C20
 

That's correct, I imagine that those would work with conversion lug nuts and modern hub covers. I just picked up a set myself. At that price it's a good option if you are into that look.

Re: 16” Tires on C20
 

Well I bought the rims and tires before coming back to this post.... I did plan on using the hub caps dang it.

Has any one added the s clips to make them work?

Re: 16” Tires on C20
 

Got the rims. Hoping I can drill and tap three or four holes and use button head machine screws to Act as the missing knobs to hold on hubcaps. I set one on there to see how it would look. If I’m successful I will post to pictures.

Re: 16” Tires on C20
 

I can't recall if I had posted pictures of the new tires in another thread or not...well these are Firestone LT 265 / 75R 16...I also had the rims powder coated white ( the originals were silver ) I like how the white shows against the black ! I'm also attaching the SPID, would like to know the type of rear-end / ratio ( I'll write this down this time )

Thanks again !

Re: 16” Tires on C20
 

Off topic, but never seen a "miscellaneous lamp" option before. Nice truck.

Re: 16” Tires on C20
 

Thanks ! Good point, would it be interior lights ?

Re: 16” Tires on C20
 

P265/70/16 on the 16x7 F@rd Accuride wheels with stainless dog dish caps I plan on going on my C20. I'll eventually get to that point. The tires came off a Tacoma my wife used to drive, and we were replacing tires on and they have fair tread. I know many cringe at running a P tire vs. LT, but I have no intent on overloading the tires, and maybe it will help with the ride of the heavy springs. My original plan was put 1/2 ton springs on, but figured I would try this combo before jumping off that bridge.

Re: 16” Tires on C20
 

I saw a post from SS Tim referring to it as a fleet code, which is odd cause yours does not seem to be a fleet truck at all. I am guessing it would be a safety light or marker of some kind that a camper special might benefit from.

Re: 16” Tires on C20
 

Big Block trucks came with 3.56 as standard equipment. There's no code for a different ratio, so if it is the original, I'd expect it to still be a 3.56 ratio.

Re: 16” Tires on C20
 

Thanks .... and I would assume it's a Dana 60 ?

Re: 16” Tires on C20
 

Most big blocks got the Dana, but not because the D60 is stronger than an HO52 (D60 is weaker). GM didn't want the big engines revving as high as a small block. The HO52 only goes down to 4.10, so they had to use the D60 to get a numerically smaller ratio. There you go, trivia of the day.....

I should mention the Urban Legend.... The legend of the HO52 3.90 unicorn!!! This mythical creature was supposedly produced by GM Canada for use in bread trucks only. This could be true, as there might be enough room to cut a 3.90. However, it would have greatly reduced load capacity due to the shallow rim under the tooth root. That said, ain't nobody on this forum ever laid eyes on one....

Re: 16” Tires on C20
 

Splitting hairs but I believe it is 3.54 standard, and optional 4.10.

Re: 16” Tires on C20
 

I'm going with 23575 R16 E-Load Range Michelin Agilis for my '72 C-20 Longhorn. Seems like thats the size my Dad always had on it. Better mileage than fatso's. I have a gascap issue with my aux tank filler cap. The filler tube has a 1-3/8" opening and I cant find a cap that gives a tight seal for it. My Dad had a boogered-up cap I think he made to fit. But then, what the hey did anyone inow about safety in them days of yore? ANYONE RUN INTO A FILLER-CAP ISSUE WITH AUX TANK CAP FITMENT?

Re: 16” Tires on C20
 

Very nice well optioned C 20! Early build '69's did have silver wheels ( carryover from the '68 model year) however Chevy did transition to white wheels later in the '69 model year run, so white wheels are correct also. If big block equipped, the 3.54 Dana 60 was used, not listed on SPID because it was the standard ratio. The HD 4spd was the optional New Process 435 close ratio, not the wide ratio SM 465 4 speed.

Re: 16” Tires on C20
 

My SPID doesn't list tires and wheels, but I've got 9.50-16.5 Firestone Transforce tires on it now. Wheels are factory, as far as I know. I'm looking to get new 16" wheels so that maybe I'll have more choice for tires. How wide do the Ford wheels go?

Re: 16” Tires on C20
 

As far as I know Ford wheels only go to 7" wide, but Stockton or Wheel Vintiques make 8" or more wide.

Re: 16” Tires on C20
 

Thanks, I have time to look into it before I buy. The tires are going to age out soon.

Re: 16” Tires on C20
 

How wide are your 16.5 rims? 6"-6.5"?
Going to 7" wide doesn't sound like much, but it really fills the wheelwell nice.
Top is the 6.5 it came with, and bottom is 7

Re: 16” Tires on C20
 

Great hubcap and wheel choice, big improvement over top photo. One thing I like about the 7" FD rims, they mimic the look of the original wider 16.5" wheels used on c 20's that originally came with 9.50- 16.5" tires.
