Making sense of wheel specs...Help!

Aloha all, My 06 Tacoma Double-Cab 4WD is still just under 100 miles, but I can't wait to get some killer tires and rims. My Tacoma is Black Pearl color and I love the black on Black look. There are some great looking rims out there, but I am a total novice and have no idea what some of the specs mean and don't know how to determine what rims will fit my truck. Anyone who can decipher the following specs and tell me what measurements will fit my 06 4WD will earn my respect for life. Thanks in advance!
Numbers in parenthesis are examples taken from web-site:
Size: (15x8)
Offset: (-19)
Backside: (3 3/4)
Bolt Circle: (5-5 1/2)

 

I have a black pearl 05 taco and my tires are from falken and my rims are running on 20". so my diva truck tire size is 295/40/20 see what you think there are some websites that have custom truck rims. see what you like. hope this helps :0)

Thanks for the reply...do you have pics of your tires/rims? Any idea what Offset/Backside and bolt circle mean? I followed some of the links to some great websites for wheels, but still can't decipher whether some of the rims will fit my Tacoma.
Thanks again....Tacoma people are way cool!

 

Just checked the falken site...cool rims, but i'm looking for more of an offroad look and quality/strength. I like the American racing teflon rims...pricey but they look really cool. Anyone have experience with them?

 

you need the bolt pattern to be 5x4.5"

 

Thanks, anyone know what "Offset" and "Backside" measurements are for?

BTW, Nice ride 2RZ!

 

4.5" backspacing is good for aftermarket wheels on 05+ Tacomas. They will be about even with the fender flares. That's what I have. The less backspacing you have, the further out your wheel rim will be away from the hub.

 

Thanks for the reply and the diagram, that is exactly what I was looking for.
