Tire Sizes
- Thread starter rtrogers
- Start date
find a metric tire size caculator and start plugging figures in on available tire sizes. none are a "true" 33" tall. they will be over or under that figure
305 and 315 are the actual width of the tire in MM, not the size. size comes from the aspect ratio which is a percentage of the tire width to create the side wall height.
What kind of tire do you want? Find a tire look at the sizes and google tire size calculator and it will tell you how tall it is. It's not rocket science.

Thank you. Read a quick synopsis on tire sizing and understand now. Please excuse me, I've only ever run stock tires and rims for work and travel; just recently needed more clearance. I don't spend my existence worrying about how to make my duramax look big and pretty. I don't drive it to attract attention, it needs to be functional.
