Sorry to beat this to death, but I'm unclear on what all dimensions mean. I'm looking at 20 X 9.5 American Racing Punisher rims that have a -6 offset and 5.01 backspacing. I have these same rims on my tahoe and they stick out a bit but not bad. What will these dimensions look like on the 4X4 F-150? I would like a wider stance but don't want to be throwing mud everywhere either.

I also can't decide between the 275/65/20 or the 285/60/20. I'm leaning towards the 275/65/20 in order to fill the wheel wells but welcome any opinions.

The truck is having a 2" leveling kit installed tomorrow.

Thoughts?

Thanks,

Jeff

 

What year model?

 

Sorry about that. It's a 2010 Lariat. Just bought it Friday.

 

Those wheels will stick out 2.5 inches farther than your stock wheels. I'd suggest a 305/55-20 (33x12.50) tire.

 

Thanks Wandell, Is that considered excessive? I don't have the vehicle here to measure the difference. I'd rather they didn't stick out past the fenders much.

Thanks,

Jeff

 

Wandell,

I was looking at the pics in your profile and notice that your tires stick out very little. That's the look I'm after. Will the offset and backspacing I listed achieve that? It's the only option I have in this style rim.

Thanks,

Jeff

 

Not Wandell but.....If you have stock 18's your rims are 7.5'' wide with 5.5'' backspacing so if you don't want the tires to stick out too far with a 305/55R20 you should try to find some rims with around 5.5-6'' backspacing that aren't much wider than 9''.

Just for reference this guy just put 9.5'' wide rims with 15 offset (5.84'' bs) and 285/50R22....is this what you are looking for?

 

You can't compare my 01 with your truck. They have completely different wheel specs. If you don't want the tires/wheels to stick out much, I'd go with a 9 inch wide wheel with close to the OEM wheels 5.5 inch backspacing.

 

That look is pretty close to my goal, thanks.

So is that considered a positive offset vs the rim I'm looking at (-6 offset)?

The higher the backspace number + the higher the offset = narrower track?

It's staring to look like I'll need to just bring my truck into Les Schwab and bolt them up see. I'm thinking the 275/65/20 or the 305/55/20.

Thanks,

Jeff

 

as Wandell explained to me years ago backspacing is a much easier way to explain the same thing, than offset.

The lower the number backspacing, the more it will stick out. So, 4.5'' bs will stick out 1'' more than an identical rim diameter with 5.5'' bs.

in the picture I put in there, the rims that he put on stick out about 1.7'' more than a stock 17/18'' rim would, then you would add whatever the additional width of the tire is over stock to figure the total it sticks out over stock (or what you currently have)
