i have 305/55/20 tires right now, and iwas wonderin what would be equilevent in a 18" tire?? would a 325/60/18 be close to this... cause i'am goin to run my stock 18"s in the winter, and want some tires for them???

 

The Nitto's are gonna be a little taller and almost an inch wider. Look at the manufacturers websites for the exact measurements.

 

how would the BFG AT's 285/65/18 compare in size to the 305/55/20???

also, what if i went down to a 17" wheel with 33/12.50/17, how would it compare to a 305/55/20??

i know the 20"s suppose to be 33"s, but they wouldnt be the same size as a 17" 33"tire would they???

 

33 should be almost if not the same as another 33. Thats the height including rim.


you can also calculate height yourself.


305 x 55% for profile height plus rim height plus 305 x 55% (2 profiles on either side of the rim)

take the millimeters and divide by 25.4 to get the inches in overall height.

 

Or go HERE and let them compare sizes for you.
