33's are for girls..

Yeah my top choice would be 4.88 but like I said I dot think I could pass up the deal. If I were buying them and having them set up myself it would be 4.88.

I know a guy that is running 5.29's with 255/85/16 tires and he swears up and down the the power AND mileage is back to stock, he was running 4.56's before the 5.29's. I will be going with 255's and 5.29's in the near future.

255/85/16?

dude....thats a skinny tire...

I quoted this from another website....

Less rotating mass- Easier to start and stop
Less reciprocating mass- Easier to dampen
Less wind resistance- Better economy and range
Less rolling resistance- Better economy and range
Easier to fit a taller/narrower tire with less lift
Lighter spare
Lighter tire
Lighter wheel
Less unsprung weight
Less weight and leverage on steering components, bearings, etc.

In terrain:
1. Less frontal resistance in mud and sand. Where is most of the increased contact patch (for flotation) gained? In the length, not the width. Tall and narrow allows for more length and greater deformation with less resistance.

It is as simple as understanding the coefficient of friction (COF), which is (Ff = Cf x Fv).

Ff= Friction Force
Cf= Coefficient of Friction
Fv= Force Vertical

As you make a tire wider, you reduce the Fv over a larger area, but gain Cf. As you make a tire narrower, you increase the Fv, but reduce the area of contact, which lowers the Cf. It is proportional, though there are times when the material interaction (lets say a drag tire on concrete) favors Cf, but those conditions rarely exist on the trail, on a perfectly flat surface. So, if a wide and narrow tires benefits with relationship to Cf and Fv are proportional, than the decision must be made on other factors, like weight, resistance, etc., as listed above.

Now of course, there are limits at both ends of the spectrum. Too narrow of a tire, and the torque applied to the surface, even with extremely high Fv (which a super narrow tire would have), would exceed the rubbers ability to resist tearing. Literally, burning rubber.

It is all a balance, with tires for most of the trucks we drive being ideal in the 9-11" wide range.

Big, fat tires are only for show trucks and tundra buggies. An expedition vehicle has an emphasis on simplicity, economy, durability and safety, none of which a 35x14.5 will give you. . .

I was going to go with 255/85 but I like these 315 quite a bit. Idk if I would go 5.29 though. Lowest I would personally go is 4.88 but lmk how you like em. What kind of tires you going to get?

4.88 w/5speed is perfect. In my research it shows that 5.29 w/automatic will get it back to stock. I am going to go with the KM2's
 
Are you talking about a 4cyl or 6. If 4 then that probably would be accurate. I assumed KM2. Not many other tires that are good in that size range.

well a 285 is really a 32x11.5

My 285s measure 33.1" tall.

Haddix, what are you running up front for suspension? Have you test fit the 35s yet? With no body lift, unless you are running OME 883s or something, it seems as though you are going to be really pushing it with those 35s. I hope it works out for you. Personally I'd rather be able to stuff the hell outa 33's than run 35s and rub all over the pinch weld. Good luck.
 
Im less than a girl, Ive got 265s lol :lol:

kepp us posted when ya get them mounted :driving:
 
I havent mounted em yet on the front. If they do rub bad I already have a bodylift at my house that I just bought. I planned on adding it but idk if im going to need it. Guess we will see.

Id love to wheel. Im not really saying 33 are for girls. Just kinda grabbing peoples attention more or less.
 
The info I have found fitting 35's is a minimum of a 1" but recommend 1.5" or more to clear that size tire. But as I have found sometimes the research is sometimes best to verify first hand.

I knew ya was playing :dancin: still waiting on the pix of them mounted lol
 
I have a 1.5 bl at the house waiting to be installed. We will see if I need it. Keep yall updated. My wheel spacers are supposed to be in on friday so Ill have pics on friday..

If you don't want any rubbing while wheeling you will need to do more than just pound the pinch welds. You will need to trim also. Based on my 305/70/R16s it seems like you will need to trim 1" or more beyond the pinch weld. I suppose you could beat on your firewall too with a BFH. That might end up being really ugly though.
 
if you do end up having to trim/pound, take lots of pics and do a write-up for the rest of us who are waiting another 50k miles till they need tires again lol
