i currently have the stock size tires on the back of my car, but i need new ones and am looking to upsize a little bit

i now have 245/35/19s in the front... what size should I get for the rears that won't upset VDC etc?

thanks!

 

try this:
http://www.1010tires.com/tiresizecalculator.asp

 

so according to this, it looks like 255/40/19 will work.... am i correct?

 

yea you can run a 255/40/19 easily.

 

I doet..............easily.

 

yes, it would work.

 

You compared a 245/40 to a 255/40 in your chart. If change the front to the 245/35 you are currently running the diameter difference becomes 4.74% which exceeds the recommended max difference of 3%.

Could be a problem.

 

205/30

 

whats the width of the rim? is it the 19x8.5?
if so i ran a 275 on my rims in the rear on my 20s that were 8.5 wide with no problems

 

wait, so with the tire size calculator, i need to compare the front tire size i currently have with the rear tire size that i WANT??

what i did was put in the stock rear size (i currently have the stock rear size) and tried to find a wider size for the rears that would work

did i use the calculator wrong?



EDIT:

all i want to do is find a larger size for the rears that will work with my 245/35/19 that i have in the front

 

haha umm i wanna upsize

 

405/40

 

thanks for being no help, 2 times in a row

 

can anybody clear this up for me please?

 

i've ran 255/40/19 on the rears with no problems
