Hi Gilles,

According to dlg.speedfreaks.org.
......... Front......Rear
1984 - 255/620 400/655
1985 - 255/620 400/655

1987 & 1988 - no teams used Pirellis in F1.

Couldn't find any data for tyre sizes in '89,'90 or '91...

Hope this helps!

According to multiple sources (FIA, F1 Technical and other forums) tire diameter from 1982 to 2016 is 660 mm (26") maximum for both front and rear tires.

It is a bit strange that Pirelli tires are 665 mm for the rear. May be it is just the specified number, not the actual diameter.

At least in FIA 1988 regulation, both front and rear tires can have a maximum width of 18".

Does anyone know if the width in the spec is overall width or tread width?
