I picked up a 2011 250 super cab last weekend with just shy of 8000 miles and love the truck but the tires are just to small for the wheel wells and would like some better ground clearance. So whats the biggest tire I can fit without lifting it which I cant afford to do right now. Oh it's on 18" rims. I also prefer a tall skinny tire. Thanks!!

 

I fit a 35" tires stock, the width was 1250 but this is on aftermarket rims that stuck out to give more clearance.

 

i have 285 r75 18 toyo mt on my stock rim stock hight f350

 

I went from 275 65 R18 OEM ContiTrac's to 295 70 R18 Nitto Terra Grapplers.
Stock suspension and XLT rims.

 

Were you able to have the speedometer calibrated for these larger tires, and were there any problems having it done?

 

My tire store recomended the same size and brand but the at2. Anyone have any experiance with them.

Thats what I have on now.

 

No.
I took it in but every option the tech tried threw a CEL.
I stood in the service bay for 15 minutes while the tech re-tired the available tire options and only the default for 18in rims would work.
Cost me $50 for a half hour of the tech's time.
They told me to come back when I find the magic setting, so far no one has.

 

Here are the Open COuntry AT tires.
I have a 4" block on the rear and a leveling kit on the front.
My speedo was off when I bought the truck and now the tires put it reading about 2mph slower than what I am actually running on GPS.

I like visuals so here's an example.

 

I second the Toyo 285/75R18E. I have two sets of them, AT's and MT's.

 

I run 305/60/20 Goodyear Wranglers on stock FORD Wheels. No lift, no rubbing (not even in extreme situations).
They look real nice but it is a bit pricey!

 

Thanks everyone!!!!!!! I thought they would fit but now no worries.

 

Jolly Mon,

I would love to see some pics... I was shopping Goodyear Wranglers for my 2012 F250 with stock 20" rims and the Goodyear dealer said I couldn't go that big with the stock 20"x8" rims.
