/ Hello
hope you are all doing well, the current tire size of my 18 SR is 245/40/19

can i upgrade the tire size to 45 (245/45/19 ) ? any body tried this ?
and what is the best summer tire from your experience ?

Thanks

 

If you do so, your front tires will rub very bad in the fender line up front. OEM tires is 26.7" in diameter, 245-45-19 will be 27.7".

I think you'll be able to get away with 255-40-19, you'd end up with 27" diameter.
