I run 275/40/18 at all corners. I did it because I don't like understeer and I like the ability to rotate the tires. Tramlining with the wide front tires turned out to be a virtual non-issue and the size is very close to stock height with no rubbing that I am aware of.

 

Cool good luck in future, right now I'm at ford seeing why TPMS not working on Stock wheels that came with car, once I put on new meats that will have the TPMS pre-installed I want to make sure wokring so Ford don't blame on new wheels and tire package..

 

Ok put one on..... I'm tired, compared to my stock they are 10lbs over all lighter and these are 20's man these look great to me....fronts were 55 rears weigh 60 my stock weigh 60 each.....here's a question, mostly highway driving..according to gas gauge...says half tank left, says I drove 150, says 182 more miles i can drive, so total highway/city driving puts me at 332 a tank, on my 19's 295 a tank......here's the question now sorry...my speedo is off by 1 to 2 mph, on gps say 60 when speedo says 61 to 62, is that why seem getting more or better mpg or is 1 to 2 mph not high enough to give me more than 40 more miles to a tanks, i have read that 20's on highway give better mpg than smaller tires, does the larger wheel also make the 3.73 gears act as a differ. ratio too? the diameter is for 19's

27.68in proposed diam. for the 20's are 26.97 in
