Just a quick question for anybody who would know. Someone nearby me has 4 BF Goodrich P275/50-15 tires for sale mounted on 4 old style rounded spoke Cragar SS 15x8 wheels. Everything looks in really good shape. Anyone have any experience having this size tire and wheel combo on their 67 Cutlass/442? My stock OEM rally wheels are showing their age. Will they be rubbing on the fender wells? Or just look bad? I have P255/60-15's now on the rear with P235/60-15 in front.

 

Make sure to check the build date on the tires. This is important as tires generally last about 8-10 years even if they are just sitting in a garage. Here's a video on how to check. I have no idea as to the rubbing issue. With the tires I mean.

 

Check the date codes. Probably fit the rear, won’t work on the front.

 

Well, for starters, you didn't tell us what car you were planning to put them on. But then again, the only cars Olds made were 1968-72 A-body cars, so I ASSUME that's what you are asking about...

In any case, 275/50-15s are a Honda-sized 25.8" outside diameter. They will leave a LOT of daylight in the wheel wells. By comparison, your 255/60-15s are 27.05" in diameter. Even your 235/60-15s are taller at 26.10" OD.
Also, what is the offset on the wheels? I suspect that even with the tiny diameter, you will have clearance problems in the front. These wouldn't be my first choice for an A-body.

 

BFG does not make a 275 50 15 tire. It's either a 295 50 or 275 60 15. Neither of which will work well up front.

 

 

They did up until recently

 

I didn't check the date code, but I'm guessing if a deleted size, they may be too old anyway.

 

Recently meaning before 2009?

 

Hey, I consider any car made this century to be a "new" car.

 

I had 275 50 15s on the back of my 66 442 20 years back. As Joe P mentioned they are on the short side vs stock.

Luckily my ride had the traditional "Oldsmobile that looks like it has a spare engine in the trunk look". So diameter variance not so noticeable.


I thought they looked great and filled out the wheel well beautifully. But they are extremely heavy and slowed her down. And it wasn't because of the added traction... She was 2 speed Jetaway and 3.23 limited slip, with over 100,000 miles. Went from a peel out on a dead punch to a chirp. Now she accelerated as if I had someone in the car with me when I was alone. If the engine was fresh with a robust drivetrain probably not much of an issue...
