Tire load index chart

The load index is the number before the speed letter, such as 102 in 225/65R17 102H. It stands for the most weight one tire can carry when inflated to its maximum pressure: 102 means 1,874 lb (850 kg).^{[1 · Oct 29, 2026]}^{[2 · Oct 29, 2026]}

The rule for replacement tires

A replacement or new-size tire's load capacity has to equal or exceed the original equipment tire's.^{[3 · Oct 29, 2026]}^{[4 · Oct 29, 2026]} The original load index is in your owner's manual or on the tire itself; the vehicle's tire label gives the size and pressure.^{[5 · Oct 29, 2026]}

Load index 70 to 126

Tire Rack's table covers the range used on most passenger and light truck tires. The US (TRA) and European (ETRTO) standards can differ very slightly for some indexes.^{[2 · Oct 29, 2026]}

Standard load, XL and load ranges

Type	Marking	Max load measured at
P-metric	Standard Load (SL)	35 psi (newer tires 36 psi)
P-metric	Extra Load (XL)	41 psi (newer tires 42 psi)
Euro-metric	Standard Load	36 psi (250 kPa)
Euro-metric	Extra Load / Reinforced (XL, RF)	42 psi (290 kPa)

An XL tire can carry more load, but only at the higher pressure.^{[6 · Oct 29, 2026]} Light truck tires use load range letters instead, covered in LT vs P-metric tires.

Swapping standard load for XL

Continental's plus-sizing bulletin gives this pressure adjustment when an Extra Load tire replaces a Standard Load original. Never go above the maximum pressure on the sidewall, and never below the vehicle maker's pressure.^{[4 · Oct 29, 2026]}

XL replacement's load index	Change from the original pressure
Same as the original SL tire	+6 psi (0.4 bar)
Original + 1	+4 psi (0.3 bar)
Original + 2	+3 psi (0.2 bar)
Original + 3	+2 psi (0.1 bar)
Original + 4 or more	Same pressure as original

This table is from a 2006 bulletin. Pressure tables vary by tire maker, so check with the maker or a tire professional for your exact tires.

Two numbers: dual load indexes

Some LT tires show two load indexes, such as 104/101. The first is the load for a single tire and the second is for each tire in a dual-wheel pair: 1,984 lb and 1,819 lb for LT235/75R15 104/101S.^{[2 · Oct 29, 2026]}

P-metric tires on light trucks

When P-metric tires come on a light truck or SUV, the vehicle maker has to reduce their rated load by a factor of 1.10. Toyo's example: a P245/75R16 109 is rated 2,271 lb at 35 psi, but only about 2,065 lb on a light truck.^{[7 · Oct 29, 2026]}
