2011 F-250 20in option, largest tires that can be run safely

2011 Lariat Ultimate needs tires. Has the factory 20in upgraded rims with . I know I can safely go up to a 295/60-20 or a 295/65-20 but can you go to 35ís? If so is there an advantage, are they bigger and fatter. I see a lot of references to 35ís but the factory wheel width is 8in. I Like the look of the factory wheels so not planning on buying any in the near future

I wouldn't suggest running a 12.5" wide tire on a stock 8" wide wheel. For the record it seems as a 295/65-20 is actually larger all around over a 35x11.5 tire. Only a 35x12.5 tire would be larger in width.

Another thing to keep in mind if you are thinking of going with the 35s especially Toyo tires is the load rating although I agree with Heavy, I would not recommend going 35s on the stock rim due to the with difference. My 35x12.5 have the 121 load rating which are below the standard for my truck. I think the superdutys are required to have the 126 load rating if I am correct. My brother has 295/65/20 toyo AT2s on his truck and is rated up to 4080lbs whereas I am only rated for 3195 which is pretty low. Both have the E load rating. Also, most tire shops will not mount 35s on a stock rim due to safety reasons.

Thanks guys! I will look at the 295/65/20.

Is there a good reference to do a size comparison on different tires? to compare width and overall dia? Maybe tire rack?

I go to the manufacturer pages. Nitto/Toyo have plenty of info that's up to date and correct.

The 295/65 is the ticket on factory 20's with no lift. There is a thread on it around here somewhere. Most manufacturers measure out to 35.08- 35.19" tall and 11.65- 11.8 wide (section width, not tread) in that size. Ive done the research. Lol.
Depending on your options, the amount of clearance will vary but they'll fit.
