Spare tire Query again
 

So guy so that I have a better understanding, currently my car has 19"s with 255/50-19 and I am switching to the staggered 20" setup with 20x10 275/40-20F and 20x11 315/35-20R.

I don't want to put run flats on the 20"s and don't mine putting one of the 19"s in the truck to used as a spare on long trips but I have heard due to the awd this will not work

Is that the case as if so I will just get run flats for the 20s but I just see better tires which are non run flats and also at better prices too.

As long as the overall diameter is the same, and the setup clears the brake caliper, you should be fine.

Thank you

Just get a 20 inch spare.
