What this size means for your Ford F350
On the 1983 Ford F350 4wd, the factory 215/85R16 measures about 30.4″ in overall diameter with a 182.8 mm (7.2″) sidewall, and completes roughly 664 revolutions per mile. Its 85-series aspect ratio gives a tall sidewall of the kind used on trucks, SUVs, and older passenger cars, built for cushioning and load. In tire terms it is a passenger (P-metric / Euro-metric) size.
The 215/85R16 and 235/85R16 differ in both width and overall diameter (1.3″, 4.3%), which usually means a staggered front/rear setup — the two sizes are not interchangeable side to side, so match each to its correct axle.
Because the 1983 Ford F350 predates many current tire lines, confirm this size is still stocked before ordering — some vintage fitments are now served mainly by specialty and classic-car tire suppliers.

How to read a tire size
A tire size like 225/45R17 breaks down into three parts:
the first number is the section width in millimeters
(the tire's width from sidewall to sidewall), the second is the
aspect ratio — the sidewall's height as a percentage of
that width — and the number after the "R" is the rim
diameter in inches. A letter prefix (P or LT) indicates
Passenger or Light Truck construction; its absence usually means
Euro-metric sizing.
Some trucks and off-road tires instead use "flotation" sizing, like
37X12.50R17 — here the numbers are the tire's overall
diameter and width in inches directly, with the rim diameter last.
Always verify against the tire information placard on your driver's-side door jamb or your owner's manual before purchasing — tire size can vary by factory option package even within the same trim.
