1967 Mercury Park Lane Convertible.
Can anyone tell me the correct size Tyre for this model?
At present the size Tyre fitted is P225/75R/15.
I cannot see the Size mentioned in the original Sales Brochure.
Thanks for your help.

Is there a label in glove compartment door, sometimes they tell. Radial tyres were available in 67.

The sizes I found for the Marquis model are 8.25 x 15" as standard and 8.55 x 15" as optional. I worked at a service station across the street from a Mercury dealer at that time and I don't remember seeing any radials on new cars then. If they had radials, they probably would have been G78 x 15" or H78 X 15". Not the nomenclature or wider profile tires we are familiar with today.

I went into the service in September of 1967, just before the 1968 models arrived and when I returned, 1971, radials were everywhere.

Thanks for your help. I looked at the Glove Box Lid, and it only lists Tyre Pressure at 26 Pounds.
I looked up the Workshop Manual and it lists the Tyres as 8.45 x 15.
For Radials, what does 8.45 x 15 convert to?

There are size comparison charts on the internet to go from the old sizes to the current sizes, for instance:

8.25 x 15 ==> G78 x 15 ==> 215/75R15 ==> 225/70R15

8.55 x 15 ==> H78 x 15 ==> 225/75R15 ==> 235/70R15
