hey guys its probably I stupid question but I cant find a straight answer im looking to switch to mud terrains I have 305 65r18s now what size would that be in mud tires ive been told everywhere from 32 x 10.5 to 35 by 12.5

 

33.6 tall according to my math

 

Thank you what about width would 12.5 work?

 

I got 12

 

Ok thank you

 

Ill show my math 305/65/18 305 is width in mm so thats just 305 divided by 10 to get cm divided by 2.54 to get inches the height is 305 (width) times .65 (percentage of width)=198.25 which is mm from rim to edge of tire for one side double that for the other sides rim to tire you get 396.5 devide by 10 for cm devided by 2.54 to get inches if that makes sense

 

I just remembered why I failed math class lol

 

Its easier then it looks lol

 

Use the tire calculator on Discount Tires website. Wont show up till you pick a tire to look at, its very handy.
