Using the above codes would result in the following axle codes:



B01A 3.42 2 pinion open 7.5" ring gear

B01B 3.42 4 pinion open 8" ring gear

B01C 3.42 2 pinion posi (OEM limited slip)



B02A 3.58 2 pinion open 7.5" ring gear

B02B 3.58 4 pinion open 8" ring gear

B02C 3.58 2 pinion posi



BO3A 4.10 2 pinion open 7.5" ring gear

BO3B 4.10 4 pinion open 8" ring gear

BO3C 4.10 2 pinion posi



B04A 4.56 2 pinion open 7.5" ring gear

B04B 4.56 4 pinion open 8" ring gear

B04C 4.56 2 pinion posi



B05A 3.15 2 pinion open 7.5" ring gear

B05B 3.15 4 pinion open 8" ring gear

B05C 3.15 2 pinion posi



B06A 3.91 2 pinion open 7.5" ring gear

B06B 3.91 4 pinion open 8" ring gear

B06C 3.91 2 pinion posi



Note: The following has not been verified:

BO7A 4.56 ? 2 pinion open

3.42 (automatic) ? 2 pinion open

3.91 (manual) ? 2 pinion open
 
It's an automatic. Looks like I have a 3:42.

This makes a difference in performance/gas mileage if one go's to larger tires. I was hoping it was going to be a 4:10/4:11.

Thanks guys.

185/65R15 = 24.5x7.3R15 - 32x10.5R15 If I can figure out if nothing will hit up or sideways. Right now I just don't know.

Changed my mind. I think I will use the size that were on my 1999 Tacoma. I really liked them sense most of my driving is on the road/back roads with just moderate off road, used to get to hunting and fishing sites. It had a great "Stance" and really looked COOL to me.
They were 31X11.5R15 or an equivalent for 16" rims now on the new truck (2001).

I don't know if the stock rims will be OK for the 2001 Tacoma or not, bay be someone could jump in here and tell me?

I hate the metric system !!
