Looking for some advice...I have a 2015 F-150 Lariat with stock 20s...I'm gonna buy Fuel Maverick rims with Mickey Thompson Baja ATZ P3 tires, 305/55R20. I have a Roush Fox Racing 2.0 leveling & rear suspension kit on there already (https://www.cjponyparts.com/roush-su...saAh8IEALw_wcB) and from what I've read and seen these should fit no problem. My questions is what size offset to get. I really don't want them sticking out from the factory fender flares anymore than an inch so does anyone know how far the +14 mm offset will stick out if at all? How about the +20 mm?
Thanks in advnace

You're adding 30mm width to the tire already (15 on each side) which is going to bring the tire really close to the fender. If you go with a 20mm offset that will be pretty close to an inch sittong outside the fender. If my math is right it will bring the edge of the tire out close to 1.5" from where it is now.

What width wheel? that will also play a factor into how far out the tire will stick. Given the same offset, a 9" wide wheel will put the tire 1" farther out than a 7" wide wheel.

Thanks for the help...found a great website after LOTS of research. I was trying to figure out how much further my new set up would stick out compaired to my factory set up...Here's the website in case anyone else is having this issue: http://www.rimsntires.com/specspro.jsp
My stock set up is a 275/55/R20 on an 8.5" wide rim with a +44 offset. So I plugged that in for the first set up, then plugged in the new set up of 305/55R20 with 9" rim and a +20 offset...It let me know that they will stick out about 1.5" farther than where the stock tires are now, so only out past the fender about 1/2".
