Oh crap! We just realized this Sunday is Father's Day and we don't have a gift for dear old Dad. Again. Never fear! Autoblog's staffers been in this spot before, so just follow our lead. Oh, and we're gonna assume that if you're car-crazed enough to be looking for gift ideas here, then your pops probably likes cars too.

Homemade tire tread wallet - $0
The folks at Make Magazine are like all journalists who love their dads. Broke. So they offer this guide from Instructables on how to make your dad his very own wallet from a bike tire, though you could probably substitute any tire with some ingenuity. Now how cool is that? They even show you how to install a "drop alarm" on the wallet in case it falls out of your dad's pocket. Or if, we're guessing, he throws it away and you want to fish it out of the trash. Just like that tie rack you made him in seventh grade. If he's not a car guy (what?!), there are also instructions for wallets made of duct tape, or a computer keyboard or an Altoids tin.

However, if you have a few dollars to spend, check the jump for some great Father's Day gift ideas before it's too late.
