Tires for 87' Fifth Avenue

[Drakuseth250]

So just wondering on how big I can go for tires on my Fifth Avenue. I've got 15" rims and I'm wondering what I can get away with, without rubbing of course.

Seems like the steel wheels were 15x7s? Would mean a P225/70R-15 side should fit and not hit.

The factory tires were, IIRC, P215/75R-15 mid-width white walls. Being on the 15x7 wheels made them look wider, for a more substantial look of things. The OEM mid-width white walls were not "wide whites" but not the normal 1" white walls, either.

I have the original honeycombs that came with the car when I bought it

"Honeycombs" are really "Snowflakes"?

I would stay with the stock size 215/70 or 75 15, I can't recall which is correct. You could probably sneak up a size or two in the rear, looks like you've already increased the width, but it wouldn't look good on the front and would increase tire roll over in fast turns (if you drive that way). Those are great handling and really comfortable cars!

Honeycombs are for T/A's!

Factree size is actually 20575R15.
With the 2.2 ratio rear gears ( despite a super low 1st gear),
I recommend 21570R15 for a good balance ( no pun intended)
of ride, handling and fuel economy.
Sure you can put on any size larger tire that will fill out the wheelwell but the car will be a dog driving around town.
I owned an 87 Diplomat for many years and tried all diffrrent sizes.
Speaking from experience, the 21570r15 worked the best epecially with the factree alloy wheels..
Hope this helps

These cars were a dog no matter what size tires. I never pulled out in traffic unless there was a huge break in the cars. Mine was a dog, and needed a slight down hill to hit 100 in it.

I've been imagining a 6.1L Hemi in one of these. Complete with white walls and stock wheels or wheel covers!
