Is a 31x10.5 to a 30x9.5 is it exactly a whole inch or less? Im about to put a 3 inch lift on my truck and im hoping my 30s will look good, a few people had 30s and a 3 inch spindle lift and said it looked good but im really just wondering. I know its kinda a dumb question but im curious.

 

neither tire will measure tru, they bothe measure small, the 31 will measure about 30 or so, and the 30 will measure about 29 or so

 

So unless you put them side by side you cant really tell?>

 

it depends on tire pressure, wheel, load, tire manufacturer and style from them... ect.

very few tires actually measure to be as big as they're supposed to be, a select few like various swamper designs measure bigger

 

If you ever see a 31 compared to a 30 you can see the difference. I have 31" BFG A/T, my friend has 30's. His look so small compared to mine.

 

Its like the difference between a 32 and 31. The bigger tire fills the wheelwell out so much more.

 

I wouldnt exactly say that is true. If its a 33 inch tire it probablly measures arouns 32.6-32.8 inches. I wouldnt say a whole inch less. There are a few tires out there that are larger then what they say.

 

most all terrains measure a inch small, some mudt terrains are even further off base, there are the rare few swamper's (only swampers) that when mounted on reccomended rim they measure slightly larger.

go outside and measure the tires actual height, not the manufacturers actual height, and u will be greatly surprised
