Convert ST tires to LT tires

Hi everyone

How do you convert ST tires size to LT tires size? For example 235/80R/16 load range E to a light truck tire size.

Google is your friend..:C

Enter: "tire size conversion" (etc) -
several sites avail to enter size of tire you have -vs- tire size you are considering.

Results are in inches.

Handy for your example, as there are few (if any) LT tires available in 235/80.

You will have to go to 235/85 - check the diameter of the new tire size for clearance (between tires) via the conversion site.

Remember an inch larger in diameter results in loss of 1/2 inch per side - one inch total between the tires.
(235/85 is an increase of 1" in diameter over 235/80)

If it's inadequate - go to a different size, ex: 245/75
(which will be the same diameter, but 1" wider).

Be sure to check the wheel pressure rating - usually stamped on the back side of the wheel.
