Will a 275/65/20 (34.07") rub on my 2005 Fx4 without a leveling kit? They will be mounted on 20x9, +18 offset wheels.

Thanks in advance everyone.

 

I think you are gonna need a leveling kit. What is the backspacing on those wheels.

 

I believe it is 5.5"

 

I could go 275/60/20, but I found the 275/65/20 for $85 (total) cheaper and they are a better tire too. I do not want to do a leveling kit.

 

I think they may fit with a leveling kit but it will be tight. If you don't want a leveling kit they will probably fit using the oem wheels.

 

Thanks wandell, you're always a great help.

I will just stick with the 275/60/20 (33") then, so I don't have to do a leveling kit.

 

do you really think they will fit on the OEM wheel WITHOUT a leveling kit?? thanks wandell.....

 

They may because they are only 275mm wide.

 

Sorry I am so naive in this area, but I dont have much experience with truck tire/offset/bs sizes.

Why would the 275/60/20's fit and not the 275/65/20's? They are the same width, just a different height. I am assuming that the extra inch of tire would rub on the front fender corner when you turned?

 

Right, when you are trying to stuff a large tire on a truck a little bit of extra height can make a huge difference. The problem here is the "odd" tire sizes. So, it's not like a lot of people are running those sizes and can give you a definate answer.

 

I see. Thanks again, I can't tell you how much I have already learned from reading a lot of your posts.

 

I have the 275/65-20s but i have a 2" leveling kit. Mine dont rub at full turn at all, leveled. I put one of them on w/out my leveling kit to see what it would look like and I believe it would have rubbed. Nothing concrete, just my opinion...

 

Thanks for the response. I am going to stick with 275/60/20 (33's) instead of the 275/65/20 (34's), since I am not going to level the truck.

 

275/60R20 would be ~32.99" in diameter vs my 305/45R22 which is ~32.80"
mine fit just right and could prob spare a good inch or two. the 275/65 are a touch above 34" so you may have clearance probs with a lift IMO. i ran across this site that has a good tire size calculator i hope a lot of you find useful

btw ill attach some pix so you get the idea of what an unmodified suspension looks like with a 33" tire





sorry dont have pix that directly relate but you get the idea. i plan to level out the front 2.5" i saw some other f150 on this forum with that size level and it looked great with 325/50R22

I have the 275/65/20's along with a 2" leveling kit and the fit is just about perfect. I doubt I'd say that with no leveling kit, though.

You should be safe with 275/60/20's IMO. That's only 1/2-inch more in radius (distance from center of wheel). The width is stock, too, so no issues there.
