Military & Tactical Tire Sizes

Military tire sizes, matched to run flats, lubricant, and tires.

Motor pools search by size, not by brand. These are the R20 and R16.5 sizes we supply run flat insert kits, install lubricant, and tires for — quoted against your contract or bought direct. CAGE 93ST9.

The Sizes

Standard tactical sizes we supply for.

Lubricant quantity is per ONE tire at install, from our own dosing chart — e.g. a four-tire HMMWV takes 16 tubes. Any equivalent lubricant works; refer to your wheel assembly drawing for the final call.

By Size

Three things, sized to the tire.

  • Run flat insert kits — segmented polymer kits built to each vehicle's NSN configuration. See the vehicle list ▸
  • Install lubricant — tube NSN 2640-01-419-6200 or 55-gal drum NSN 2640-01-457-5552, dosed per the table above.
  • Tires — General and Continental lines for military and commercial fleets, sold alone or as complete run-flat wheel assemblies.

Questions

Size questions we get.

What size tire is on a HMMWV?

The standard HMMWV tire is 36x12.50R16.5 on a two-piece wheel. The M998 family and its up-armored variants run run-flat-equipped wheels in that size — insert kit NSN 2640-01-419-6202 — and the install takes 4 tubes (46 oz) of lubricant per tire.

What size tires do military trucks use?

The tactical truck fleet runs R20 sizes: 395/85R20 (equivalent to 14.00R20), 12.00R20, 11.00R20, and 16.00R20 among them. We supply lubricant, inserts, and tires across the R20 range, quoted per wheel.

Do you sell the tires too, or just the inserts?

Both. Toota is a distributor for General and Continental truck and specialty tires, and every tire we sell can ship as a complete run-flat wheel assembly — tire, insert, CARC-painted wheel, torqued to spec.
