Model Khloe Terae Bikini Car Wash ... Ready to Service!

Jeep Wranglers don't have your standard trunk, but that didn't stop Playboy model Khloe Terae from putting hers all over one ... and in nothing but a red hot string bikini!

Khloe wiped down the custom job -- it's a Jeep Wrangler JK -- for a photo shoot at DCD Customs in SoCal ... and there's a lot more to these pics than just her fat tires.

The last Wrangler JK rolled off the assembly line in Ohio last week, so there's extra value in this 4X4 ... and not just because Khloe, who's a a big fan of water, gave it a rub down.

And that's your T&A -- tires and ass -- bonus info. Enjoy!
