Hey all,

Looking for some guidance…. I have gone through most of the posts on here as well as the resto docs RE: factory supplied GoodYears (225/60/15).

I know there are re-pops available as well, however my question is more geared to period correct as in what was actually issued back then…

I see that some of the resto docs reference the GoodYear EAGLE GT+4, then I also see some mention in threads of the Good Year EAGLE VR60’s.

I found advertising literature from 1986 introducing the debut of the GoodYear GT+4’s, so I’m assuming these were first issued starting in 1986 based on the literature.

For the 1987-1993 SSP’s, was there a change over from the Eagle GT+4 to the Eagle VR60, or is there definitive confirmation that all 87-93 SSP’s always came with the Eagle Gt+4 (if equipped with the GoodYear brand)?
