unclear reference to a larger truck

140ft.lbs is VERY tight- at least on our cars!

(Maybe you are referencing a larger vehicle spec.)
I guess I didn't make the reference clear; the truck that I referred to was my '04 Chevy 2500HD WT, with eight-lug wheels. It does require 140 ft-lbs torque, which seems to have been exceeded on all three sets of new
tires I've had installed at Discount Tire and NTB. That's when I started carrying the breaker bar.

Previously, 1/2" diameter, 5-lug and even 6-lug Chevy trucks only required 90 ft-lbs (actually 65-90, prior to the mid-70's), and when they were overtightened, I could still get them loose. But, when the lug bolts/nuts went to 9/16" on the eight-lug wheels, it seems all the tire techs decided to use their most powerful impacts to secure them. I never expected the same on the X5.
'01 BMW X5-E53 3.0i (born 7/13/01)
topas-blau, Leder-Montana grau,
my new favorite project car

Plus four GM vehicles, Daily Drivers, and modified trucks for hauling & camping:
3 Chevys:
'09 HHR Panel LS 2.2L,
'08 Cobalt Coupe LS 2.2L,
'04 Silverado 2500HD WT Reg. Cab
+ a '98 GMC Sierra 1500 Ext. Cab

- and 20 others, now gone, that I've had over the last 56 years (not counting the stillborn "1965 ChevyII altered/gasser project")
