Re: Which size again?
My plan was to go 275/40/17 on my 9.5 rear rim. My fronts will be 225/45/17 on 8in. But im leaning to a tire that only comes in 255's and smaller. So do I still get the 255/40? or do I go 45 now? Im still unclear on why we put a 40 series in back and a 45 in front anyway? Sorry if I dont make total sense I have a 3 yr old on my back and hes CHOKING me!
I would go 255/45 for the rear and still use 225/45 for the front especially, if you've lowered your car. The 45 in the rear will fill a little space, and the 45 up front keeps it reasonable for height (I believe it'd be 25.4"). In my case (with front dropped 1" and rear 1.5"), I'm running 235/45 front & 255/45 rear. Here are pics of these very sizes:
As you can see, the car sits level (despite on pic taken on a slant). But keep in mind; I dropped the front 1" and the rear 1.5".....and then 235/45 sits 25.4", which is a 1/2" lower than the rear 255/45 @ 26.1".
