Whose here with wheel spacer?

[Markuson]

Stock LX570 20" wheel offset is 60mm.
TRD Pro 18" wheel offset is 45mm.
So, with TRD Pro wheels, it is tuck in a little further by 15mm.

Spidertrax 1.25" = 31.75mm

TRD Pro + Spidertrax spacer put out the wheel by 16.75mm. It's not much by number. Does it have a side effect?

I thought TRD Pros were same as stock at 60.

FWIW, Rock Warriors are 50mm

TRD pros (in black) are Et60..... to optimize my set and the 305's I'm having a custom hubcentric 10mm spacer made for the front with slightly longer studs, and a set of 1.5" spacers for the rear to match the stance. That should give me 13-15mm to the UCA and adjust the scrub radius back ..... ( I did have a set of 18mm built jsut in case that isn't enough....)

I used Motorsport Tech ( in AZ) as they'd built some custom stuff in the past for my german cars - great guys and fairly fast and very nicely finished produc - hoping they'll be here by the weekend .......

Scrub radius discussions are more prominent in racing circles where handling is a primary focus, and handling qualities at extremes are more pronounced. Fortunately, trucks seem more tolerant of these geometry changes as they have more advantaged steering ratios and we don't typically drive at say 8/10th and beyond where ill handling behaviors can be a bear.

One interesting and fortunate thing is that as you go with taller tires, the optimal offset tends to be farther out from the hub. From the previous graphic, if you look at the slanted line and see where it meets the bottom of the tire...now imagine a taller tire, and you'll see that less backspacing (e.g. ET50 of the rock warriers) would be optimal for the recommended 33's.

trd pro offset is 60mm

Oooppss..so sorry, it's other way around
