Hey guys, I recently got some new wheels, 20x9 up front and 20x10 in the back. my car is on stock suspension and at the moment i have 245/35/20 and 275/30/20 tires. i've seen differing opinions on tire sizes, should i be running a front tire with a profile of 35 or 30? i've seen many posts that recommend a 245/30 but i've also read some that say a combination of 245/30 and 275/30 in the back would leave the back wheels higher up which is no bueno. if someone could clear that up it would be much appreciated. also, i'm thinking of putting 285/30's in the back when i replace the tires. would that change anything relating to my first question? thanks in advance.

 

Your current set up the front tire is actually slightly bigger than the rear being .3 inches greater in Diameter and .8 inches bigger in circumference.

With the 245/30/20 and 275/30/20 sizes your rear tire diameter would be .7 Inches greater than the front with a 2.2 inch bigger circumference as well

If you put 285/30 in the back leaving the fronts as they are now you would actually be the closest in diameter and circumference out of either of the other two combinations. They are almost spot on identical.

I think most of it is personal preference as to what aspect ratio you want to run.

Hope that helped clear up your question a little bit at least.

 

yeah that helped a lot. thanks!

 

Best to move into the 245/30-20 and 275/30-20 combination. Better overall diameters and decent tire selection.
