What is the stock rim size for a 08 Lariat supercrew 2wd?

 

Either 18x8" or 20x8.5"
It should be printed on the door tag on your driver's door.

 

I would bet you have the 20" rims but Chandler is right on with the sizes.

 

The reason I'm asking is I bought the truck with 20" Foose wheels on it and I think they're thowing the odometer off. I was checking the mileage using the truck odometer and my Garmin nav unit. The speed odometer is off from my Garmin by 3mph and my trip meter was reading less miles than the nav unit. I've used the garmin in my old truck and the wifes Bonneville and they read right on with each other. Anyway I like the look of the factory Lariat wheels better that these Foose wheels. I'll check for the tag and see what it says. By the way if anybody is interested in trading a set of factory Lariat wheels in good condition with good tires for a set of 20" Foose wheels with good Falken tires and you live in the Baytown Texas area I'm interested in doing that. I cleaned the rims the other day and they're like new. I don't know what kind of Foose wheels they're called but if you go to the Foose web site they're just like the ones that come on the Foose edition F-150. Shoot me a PM if you're interested and I'll email you some pics. I go offshore Wensday so I'll be out of pocket after tommorow for about a week.

 

Wheel size has little to do with the speed reading. Overall outside tire diameter is the key.

What size tire is on the wheels? 275/55/20 was stock. Being off by 3mph is really pretty normal.

 

Roger that.
