1967 Buick Riviera Tire Sizes

[Guest 67BlackRiv]

Hi all,

I need some new tires for my 1967 Riviera. It currently has HR78-15 tires on it and they work fine, but are very old, and I want to be able to drive the car without worrying about a blow out. I'd like to get some vintage redline tires. Would any of these tires work?

Or, would someone have another suggestion regarding tire size? I found online that an HR78-15 tire is comparable to P225/75Rl5, P235/70Rl5, P255/60Rl5, P275/50R15 tires, but again, not sure what to get, especially given that Coker doesn't offer any of these exact sizes.

Thanks!

Tire tech and specifications can become mind boggling but, IN GENERAL, use the series # as a guideline to make your choice. A typical passenger car tire which provides a good ride and tallish sidewall is a 75 series tire. As the height of the sidewall decreases, as in a 60 series tire, generally, ride quality suffers but handling becomes better due to less sidewall deflection. Your choice depends on your personal preferences. Are you more interested in preserving ride quality or improving handling? Is the car a GS model? Jamie? Good luck,

Its not a GS model. Im not planning on throwing it into corners. I love the car and baby it. Thanks for the suggestion.

I run a 235/70 on a 67 I had for many years. A 225/75 is also a good option.

If you want a redline I would suggest a diamond Back III. FAQ | Diamond Back Classic White Wall Tires - Vintage Tires - Redline & Redline Radial Tires for Antique and Classic Cars

They are expensive but they are very high quality tires.
