Let me see your tires

Looking for ideas for my 67 skylark. I know what rims I want, but I don’t know what tire size so if anyone has any pictures of rims and tires with the Tire size I would appreciate it!

 

I run a 275/40-18 on a 9.25” wide wheel in the rear with 5.25”bs and a 255/40-18 on an 8” wheel with 5” of bs on the front of my 66. Rear fender lips were folded before I got it and now that I did a disc brake swap I’ll need to drop to a 245 tire in the front for some clearance. Fills it up nice though.

 

Hello All.

I've been searching the site for the best thread to ask on, and this seems to be it. I have a 70' GS with custom Schott wheels on it currently (that I 'like' but don't 'love') and I'm looking to swap them for the classic Buick rallys. My problem is, understand what will and won't fit the car the best. It seems as though backspacing is key (perhaps obviously) so the tires don't rub.

I'm considering these Boyd Coddington replicas from Jegs, in 15x7s for the front of the car and 15x8s for the rear:

Before I bought my car, I looked at this 72' GSX Tribute here in WI... that had a real nice set of Buick rallys on it (don't know the wheel sizes), but it had 235/60R15 BFGs (front), 275/60R15s on the rear... and it looked absolutely killer. The rear wheels almost look like 15x10s, as they have a 'deeper' look to them. Does anyone agree? Again, the yellow GSX Tribute is not my car... I just shared as I really like the stance and look of it. This is what I'm try to replicate on my car. The combo on it 'fills in' the wheel wells real nicely... and it didn't rub when I drove it.

Any advice on where to go from here would be greatly appreciated. Thank you,

Gregg

 

Unfortunately those wheels at Jegs are Magnum 500s... Ford wheels. The problem is they have the wrong bolt pattern for our Buicks (5x4.5 vs 5x4.75).

 

Hello again.

Dangit. I knew the correct bolt pattern for the Buicks... I just got excited when I found the wheels on Jegs, and didn't notice the 5x4.5. Shoot.

Well... these appear to be correct, but they only have 15x8s:

Are they decent wheels for the $189.99 price? They look nice from the pics, assuming that's in fact how they actually look. Otherwise, the Parts Place has Wheel Vintiques in stock... but they're pretty pricey at $349.99 each!!

I guess I'm looking for direction and/or advice on getting replica wheels (vintiques or Boyds) with 4.5" backspacing. I know a ton of people have done the calculations/research/measurements for their 70-72' GS', so I'm asking for their advice on "what fits" or "what doesn't". I, again, would love to replicate the look of the 72' GSX Tribute in the pics I shared... but I only know the tire size, not wheel size or spacing, etc.

Thanks in advance!

 

Very true - I bought 15X10 wheels from a board member that he had on his car. I needed a 1/8" spacer to make them work on my car. It was that close! 295/50's on the rear.

 

I'am going the Mickey Thompson tires for the rear of my 70 GS 455 because I can't get traction with my BFG Redline tires.

The rear MT will be 275/60/15 street drag slicks, on my original rally wheels.
These drag slicks do have a tread pattern in them in case I run into a rainy day. But the tire compound is much softer than the BFG Redlines I currently have for a much better traction.
This is my first BBB, and the touque output is so great, even at idle and flooring it, the tires go up in smoke. Looks great, but spinning isn't winning, Lol.

The front will be MT 245/60/15.
This comes in 2025. Vet

 

These are my wheels on the old car don’t have them on the new car as of yet. 17x8 front 18x10 rear 6” backspace 295/40 tires in rear are a bit close to the frame but going to disc someday and it will push them out a little bit, I have a Tanks Inc EFI tank with the corners cut so exhaust clearance won’t be an issue
