Take---Offs are one of the best ways to get clean straight set of rims off a shop not as cheap as private party purchases. I still want to see mounted and spun rims before buying period!
StockWheels I bet all their rims they had mountedand spun then checked for any flaws vs shipping out crap like Ebay with their "as is no returns" in small print listings.
My question, what they consider good enough in slight wobble (axially) or egg shaped (radially) the rim bead areas. Also a constant rim width spacing.
I have run across three different 94 and 95 D1's that had wheel vibration issues and it was from bent rims from tyre shops not curb or hard hit off a rock off road impacts. This over a 22 year span owning a LR. At one local alloy rim repair shop I was told the rims for LR's were soft able to bend vs crack from off road impacts including smacking curbs plustyre shop monkeys catching a rim lip on the vertical shaft machines busting beads. Being lazy applying pressure inn only one location and not turning the tyre and working an area 4-5 inches away. A little tyre mounting liquid applied working into the bead greatky reduces the applied pressures to break a bead vs dry.
Add the monkey catching the rim lip itself then standing on the foot valve getting the maximum usual shop line pressure of 175 psi applied to the ram able to apply extremely high side loading pressures against the rim, bingo now a bent wobbling rim.
Second item, tyre shops did not have the correct centering cone diameter to balance wheels then using the adjustable spider. These are worn out POS items having connected studs by a gear system having a lot of gear mesh backlask placing the wheel in an eccentric orbit. Next the monkey telling you your rims are out of round or just able to balance them anyway. Yeah right half azzed shakers unless your hubs are designed to maintain the same orbit of the balance job.
A 3/8" steel disc machined to slide fit into the rim's concentric pocket, disc ID machined (bored out) out to just slide onto the balancer arbor, BINGO rims spins like a top looking as if standing still now the wheel can be perfecly balanced.
TerraFirma wheel spacers of 165 mm D1 & D2 stud circle do not make concentric contact with the rim resulting in all four wheels having vibration or out of balance issues to a point people removing them off their D1 and D2 vehicles.
Their spacers rely on the coned lug nuts and not the hub for concentric alignment and load bearing vehicle weight now on the studs and not trasfered to the hubs. Adding insult the spacer's concentric lip DO NOT contact the rim concentric area to maintain concentric wheel alignment by five concentric lip sections only bslanning across the relief sections of the rim for clearance of the drive axle spokes and bolt heads.
Clearance between the parallel lug nut body and larger bore of the rims is how much the wheel is hanging down now in an eccentric orbit hence out of balance which I recall is a 57npound mass the rim and tyre combination. Instant vibration issues, talking 2.97 ounces out of balance each wheel times four corners shaking.
Like others I was unhappy and ****** as once installed NO RETURNS of these defective product spacers and not cheap even on sale.
Ended up making rolled stainless shim stock 3/4" wide inserted into each stud bore now having a thumb slide fit to parallel shank lug nuts solving all the vibration issues. Removing the thin tin valve stem cap is enough weight to start the wheel to rotate out of balance on the static wheel balancer I built for my motorcycles.
A spare D1 hub mounted on a stand with a balanced wheel spun up by a 2 Hp 3 phase motor and variable frequency drive able to spin wheels fron 9 to 78 mph. This passing above the primary and secondary out of balance rpm zones. Radial as well axual balance checked as turbine smooth afterwards checking the tyre shop spin balance. They have a plus/minus 1/10 ounce balance machine tolerance which is only good if the machine has been checked and calibrated which is a No in tyre shops. No weights exposed on the outboard and inboard sides of the rims per customer instructions by me.
There is a reason why I dismount and mount my own tyres as well rotate the tyre to find the mininum amount of weights required to balance. Your not going to get this attention in 90%b of tyre shops.
I'll get flamed for this reply then called a wise azz.....~~=o&o>......
