L78 15 RADIAL?

[60eldo]

  I have a L78 15 Uniroyal Radial tire thats a 2 in WW,,is that strange?  It seems almost new,,it was in a 76 cad as a spare,,still has nubs. I thought these were just bias tires not radials

Good tyres what is the question?

The original Uniroyals on my '76 are an 1-5/8. I purchased a set of 1.6 American Classics.  I got to looking and finally measured. That little extra width really made a difference in the car's appearance. I think I read these were an option.

My dad bought his 76 DeVille in 78 with 10,000 miles; it still had the original tires.  I remember they had a 1 7/8 inch whitewall.  I remember it well because a year later my brother bought a 79 CDV and we had an argument whether the whitewalls where the same width on the different cars, so we measured.  76 was 1 7/8; 79 was 1/5/8.

And yes i remember they were BF Goodrich LR-78 x 15.  When we got new tires we had to have it explained to us that the P235 x 15 were the same size as the old L.

I also remember my Mom's 75 Plymouth (bought in 77) had letter-sized tires.  So it must have been around 1980, give or take a year or two, that the "P metric" sizing took over, while radials started appearing in the early '70s.

I know this is a bit of a tangent, but where are you guys shopping for your wide ww tires?  i'm looking for a set to put on my recently acquired 79 Seville.  I can buy a decent set of blackwalls for about half or less of the comparable set with the ww...what's up with that? am I shopping in the wrong place? I'm not locked into a particular width, but something wider than the normal 3/4.  Can somebody direct me to the "bargain bin" or wide ww tires so I can rummage through? LOL!

Don't buy cheap ones, they turn yellow in a few months.
Diamond Back Classics are the best ones out there that I have found.
