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.

There are online sources that will tell you your tire dimensions. For ST235/80R16's you have 2 LT choices unless you can/want to go to a much larger or smaller size or change rim sizes.
The LT245/80R16's are very close to the same height and about .25" or less wider. The LT235/85R16's are about 1" taller and about the same width.
I went with the LT245/80R16 Michelin XPS Rib. My existing tires are on 6.5" rims. The Ribs manufacture width lists them at .25" wider but thats using 7" rims. When mounted on my 6.5" rims the width is just barely wider than the ST's. A very close match.
ST tires generally have a higher load rating than LT's but its difficult to compare. ST tires show the absolute max rating not to exceed. The LT tires typically are underrated by 20% to allow a safety margin.
The 245 is LT245/75R16! Chris
