P245/75 R16 on my C20 3/4 ton 2wd- what rims?

[VA72C10]

I thought they were the stock split rims but now guessing they aren't. Was going to order new tires tomorrow while there was a sale on the
Transforce HT tires Size: 9.5R16.5LT. But when I went out to confirm the tire size it's just a 245/75 16". Guessing the PO changed out the rims???

Can anyone identify what vehicle these rims are off of?



going to go get try better pictures of the rims but it's dark....

Over 17" diameter

I realize 16" tires shouldn't fit on a 16.5" rim...just being 100% sure

[VA72C10]

And prefer a 16" as it's a much cheaper tire

With 245/75-16s mounted, you do have 16" rims -- ignore the total outside diameter of 17" as per your 2nd pic. Many wheels have diameter & width stamped on the back side of the rim. For the record, the 9.5R16.5LTs you mentioned are virtually the same size & load capacity as most 245/75-16s.

Thanks, just making sure I wasn't missing something...didn't want to have to take a wheel off to look....may tomorrow when I'm in the shop up on a lift hopefully...

Good to know it's close to the factory size. I'll go back with this size when I buy new tires. Can anyone identify what these rims came off of (just curious) Thanks

Based on the hubcaps, look like an 80's Chevrolet 3/4 ton truck or Suburban.

Agree, 1973-87 GM 3/4 ton and 1 ton (SRW) trucks. Getting tough to find straights ones out there anymore, guess 25+ yrs will do that.

[VA72C10]

Thanks! Just glad they're 16" already so it'll be more affordable tires...I will be putting the "correct" caps on (73-75 caps with blue bowties added)

Yep,those are the 6 x 16s that came on GM trucks from '73 till they stopped using that type wheel in '91 on the RV models. You could easily fit the 265/75s for a slight bit of beef,or go with a more original looking profile for 16s with 235/85s. Those are the closest to the 7.50s that would be mounted on 16" wheels from factory

Thanks for the tire suggestions. I'm going to check with a local used tire place first before buying new....I've gotten almost new Michelin tires for a van we had for about 1/5th the new price. Having a few good options is helpful...I'd be happy with the stock size, what's on there now, or a "beefier" look
