Rim clamp tire changers engage the wheel with claws on the turntable - and they have a spiked surface to grip the wheel barrel. Those machines allow for near “touch less” tire demounting and mounting, as the wheel doesn’t need to be locked down to a hub arbor and no tire irons are involved.Well…heck. I bought a tire and had it mounted, but it was a mixed experience.
I ended up calling 3 local places - Discount Tire (over $200), Tire Discounters ($180), and NTB ($154).
All these quotes were for some kind of off-brand tire such as Westlake or Linglong, etc.
Ended up choosing NTB for $154 out the door (parts, labor, & tax) to dismount both tires, transfer the Bridgestone Dueler H/T (identical to the other tires) to the alloy wheel, and mount a Linglong Crosswind 265/70-17 to the steel spare wheel.
The price of the tire is on the receipt as $118. So I paid about $36 in labor & taxes.
The Crosswind is a Chinese copy of the Michelin LTX/Defender LTX, and I’d say, appearance-wise, its pretty darn close. The biggest difference I can spot is that the sipes aren’t full-depth like the Michelin.
So far, so good. Satisfied with that tire and the price, they were nice to deal with, got it done quickly, etc. Which I appreciated.
What I didn’t appreciate, was the scratches they put in the inner bowl of my wheel, with a flathead screwdriver blade, or similar, scraping the old wheel weights off. 🤬
I specifically mentioned that this is a new 2021 vehicle (and wheel), and that I didn’t want any scratches. He said no problem, our machine has a rubber-coated duckbill.
Well, I inspected the face of the wheel before I left. But I neglected to look at the inner barrel of the wheel. 😤
Their machine Also put some nice “puncture” marks (7 pairs of them) around the inner barrel. I assume whatever machine they used has something that expands into the inner barrel in order to secure it. But it caused damage. Cosmetically I don’t really care about the divots, as they’re not really visible (the scratches are). But they might eventually be starting points for corrosion, and should probably be blended out, alodined, and painted, to prevent corrosion eventually starting at those points.
I’m very upset, mainly, that someone was careless enough to use a flathead screwdriver or the like to scrape off the wheel weights. And I’ll be contacting the manager on Monday morning to arrange for them to either repair the damage, or replace the wheel.

In the last photo, above, you can see 2 of the little “puncture marks” or “divots” that were left by their machine. Why it would operate like this, in a way that can, and has, obviously, damaged customers’ wheels, is beyond me.
Maybe someone here understands the type of machine that was used, and can provide some insight? Was there negligence that caused these divots? Again, I can’t believe that a machine would be designed in a way that could potentially cause damage like this. If so, I’d certainly like to bring it to NTB’s attention, to hopefully prevent others’ wheels from being damaged.
They do make a scraper to take off tape weights and a good tech will use that and brake cleaner to take off the double-sided foam tape(3M usually) on the wheel.
