Hello .. Need some opinions. I got a 05 f150 with about 7.5 lift, i have 35"s now and they look like baby tires.... Would 38s fit or is 37s pushin it? ... I dont have any friends with big tires were i live now to hold next to so i have no idea.

 

I take it you have a combo of suspension plus body lift to achieve that lift? For me, tire size would depend on rim specs, gear ratio and width of tire. There's a few threads floating around here of lifted trucks. You'll just have to search and see what works best for you.

 

Need to know rim width and backspacing/offset and 2wd or 4wd for starters.

 

Its 4wd .. I dont know backspacing bit they Are 12.5 tires and the rims are about as wide.. Im just qurious because i need new tires and i want to go bigger and get nicer rims but i wanna no how big i can go without lifting my truck up more

 

Pull off the wheel and check to see if the size is stamped on the inside, normally it is. Otherwise at least post the model of the wheel if you know or a picture of it so we can narrow it down some.

Otherwise anything we guess at could be completely wrong and you could end up with a set of tires that are too big and won't fit properly.
