What size rims are compatible with my 05' RCLB?

Hey there,

Never bought new rims before, and looking for some black steelies for my 05'. I've only ever bought rims/tires off craigslist and put them on my trucks, so I'm confused by the variety of measurements and numbers being thrown around while looking for rims. I know I need 6 lug nuts, and 16 or 17in, but I don't have a clue what other measurements like '6x5.5' 4.25 bore, or -12 represent.

I'm just looking for some cheap steelies before I invest in some new tires soon. Any help is appreciated

 

The first number you have is the lug pattern (spacing/arrangement of lug studs). Your truck will be a 6x139.7 lug pattern

Second is the hub bore diameter. If you have ever taken a wheel off your truck before you will notice a lip, this is what actually carries the weight of the truck and prevents your lug studs from shearing off the truck. Some vehicles are hub-centric and that bore size is important, lug centric vehicles are designed to ride on the lug studs and the bore is not important. This number is very important for Toyota trucks and I don't remember what your measurement is off hand.

Third is the offset of the rim. In the simplest terms a more positive number pushes the wheel mounting surface to the outside of the wheel and pulls the tire underneath the truck, a more negative number pushes the mounting surface to the inside of the rim and pushes the tire outside the wheel well and gives you the 'cool diesel-bro' look (this often requires tons of cutting because it changes where the tire is in turns and pushes it into body panels and other things). I think stock Toyota wheels for your gen are in the neighborhood of +30 but I also am not familiar enough with 1st gens.

@shifty` and others in the 1st gen crew can definitely confirm these numbers and generally acceptable ranges that work

 

Plenty of threads on this in the 1st Gen subforum. I'd propose any of these :
