Here is a list. Not sure if yours are the X-runner wheels or not but it is the only 18" listed. But I know that some 4runner, sequoia wheels are 18"
Hey, I know I'm new, and everyone hates that new guy who comes in and wants to change something but I've noticed many, many new wheel threads pop up just in my short stay here. I was thinking that one way to alleviate this, and I've seen this done on many forums, is to sticky a thread with with the general information commonly used to answer all these repetitive threads. As a I start I'd like to propose a sticky on the specifications for the stock wheels available to Tacomas. Personally, I own a 2nd Gen with the 16" steelies, so I would need input from other members, but this thread can also be expanded to include info for 1st Gens as well. Useful information would be: diameter, width, offset, backspacing, weight and bolt pattern. Here is what I know so far:
2nd Generation Tacoma:
Base Steel Wheels: 15x6, +40 mm offset, ? backspacing, 5x4.5" bolt pattern, ? hub bore, ? lbs
SR5 Steel Wheels: 16x7, +? mm offset, ? backspacing, 6x5.5" bolt pattern, ? hub bore, ? lbs
TRD Sport Alloy Wheels: 17x7.5, +30 mm offset, 5.5" backspacing, 6x5.5" bolt pattern, 108 mm hub bore, ? lbs
TRD Off-Road Wheels: 16x7, +32 mm offset, 5.25" backspacing, 6x5.5" bolt pattern, ? hub bore, ? lbs
X-Runner Alloy Wheels: 18x8, +30 mm offset, ? backspacing, 5x4.5" bolt pattern, ? hub bore, ? lbs
TRD Baja Alloy Wheels: 16x7, +? mm offset, ? backspacing, 6x5.5" bolt pattern, ? hub bore, ? lbs
Ivan Stewart TRD Alloy Wheels: 16x8, +1 mm offset, ? backspacing, 6x5.5" bolt pattern, ? hub bore, 23 lbs
TRD FJ Cruiser Allow Wheels: 16x7.5, +15 mm offset, ? backspacing, 6x5.5" bolt pattern, ? hub bore, ? lbs
This list is far from complete but I will try to continue to update it if people offer up the needed information. Perhaps even expand this to include tire sizes as well?
