I need your help, have a 2008 F150 Lariat crew cab with stock 275/65/18's. The truck has been leveled out and would like to know the what is the largest tire that can fit w/o any rubbing and I mean w/o ANY RUBBING. Thanks in advance for your help!

(FYI this is not my truck, posting for my little cousin)

Thanks, great to be here!

My issue is that I dont have access to the truck, he is up at school. He is coming down for a short while for the holidays and they want to surprise him. Off the top of your head what size you think? Maybe 285/65/18?

 

[Mr Mac]

2WD or 4WD? Road use, off-road use or both? Street tire or off-road tire? Will you keep the stock wheel size or are you looking to increase the diameter and/or width?

285/60/18 should be fine inside the wheel wells. I'll measure mine tomorrow and let you know what I come up with.

4wd, mostly street use with minimal off road use but I know he wants an AT tire. I am leaning toward something like Firestone Destination AT or General Grabber 2, etc. Keeping the stock rims and looking to definetely increase the width and possibly the height but its not important as the width.

Probably the easiest way through this would be to call a couple of different dealers and ask them and then compare notes. They'll know pretty quick what will or won't fit these trucks.
