Tire sizing question
Ok, Tire guru's! Here it is. I am currently running 325-30-19's on a set of 11.5" CCW 505As and they hang out of the fender well about a quarter of an inch. CCW told me that if I go down to a 305 that they would tuck nicely. SO with that said... what side wall will I need to run on the rear with 305's to make up for the difference in the side wall reduction that comes with the width reduction. They dont make a 305-35-19 and I dont want my computer going haywire on me for having to big of a tire up front.
Can someone post the equation or let me know what will work. Thanks fellows!!!

I just ordered a set of the T10s from CCW. Supposed to be here Monday. I ordered 18s for the front and 19s for the rear. The sizes that John recommended are Front 275-35-18 & Rear 305-30-19. Hope this helps.

You will need a 265/35/18 front tire to better match the sidewall of a 305/30/19 tire. The sidewall of the 265/35/18 is slightly taller than the 305/30/19, but it is closer than using a 275/35/18 front tire.

Thanks, guys. I left for Fun Ford weekend in Ennis with some friends and didnt get back to this very quickly. I would really love to keep the 275-35-18's in the front so is there any other options? This is why I hate 19's! Not many tires at all in this size to choose from. I think I may go ahead and buy the L5 fender flares and space out the rims.
