I'm thinking of putting the Rancho 4" lift on my 06 F150 Lariat Screw 4x4. My question is, what size tires would I get. I want to put 35's on my stock 20's but I'm not sure about anything else like width. I don't want to have rubbing issues. Thanks for any help.

 

what is the backspacing on the stock rims?

 

it would work
plenty of people have done it & i believe theres a few on the site that have

 

I don't know what the stock backspacing is. Thats why I need the help with the tire size. I figured someone has to have done the same setup before. Thanks

 

The OEM 17 and 18 inch wheels are 7.5 inches wide and have 5.5 inches of backspacing. I'm not sure about the OEM 20's. I believe they are a little wider.

 

sorry to barge in on ur thread, but isnt ther a certain equation to find out how big of a tire you can put on your lifted truck like one inch for every 2 inches lifted?

 

No not really. Your best source of information is sites like this where people can give you real world experiences. A lot of suspension companies have "fitment chart" but they are usually very, very conservative.

 

well then what width should i get if i buy a 38" tire for the lift i was talking bout in my thread. i had to find a thread that was active so i could git some answers thats y im in on evryone elses

 

That gets a little confusing for eveyone when you do that. What tire, lift, 4x4, 4x2, ect?
