Looking for recommendations on a torque wrench for swapping wheels.

I'm leaning towards this 1/2" Gearwrench 30-250 ftlbs click style wrench. The stated accuracy is +/- 3% and its seems to deliver that based on Youtube testing. And it seems like it will fit in the factory tool kit compartment.

Is +/-3% accuracy sufficient for lug nuts? Or is it important to have something more accurate?

Only reason I'm giving it a second thought, is if the lugs are not all tightened evenly (say 94lbs for some and 100lbs for others) will that cause or add to wheel vibration?

I'm swapping the wheels on my 2025 LC 250. It's been a while since I've had a car that I wanted to build out, and the same goes for tools. When I was younger, I simply walked into Lowes and grabbed a click style torque wrench off the shelf and didn't give things like accuracy/tolerance much thought. Set and forget it.

Wheels and tires are coming already mounted and balanced, figured I could handle the swap on my own but may opt to take it to shop to do the swap if they're likely to use a more precise torque wrench. Though I've used the mobile tire repair shops before (no dedicated/national chain tire shops within 2 hours drive), and I doubt they're using a $600 Snap-on torque wrench or even bothered to check what the manufacturer suggested torque specs were.
 
I’ve used a husky torque wrench that’s the same spec and never gave it a second thought. A click style 50-250 ft-lbs from snap on is rated at 4% +\-. IMO if you’re that worried I’d buy a gear wrench, Icon or husky and send it out for calibration and call it good.

That accuracy range is pretty much standard across any normal torque wrenches you'll find, and way more accurate than the kid in the tire shop running your lug nuts on with an air impact! I'd just get a reasonable quality torque wrench and call it good, no need to break the bank or worry about getting too precise on stuff like lugs.
 
Wheel lug torque is not going to be as sensitive as something like head bolts. The overwhelming majority of cars on the road have never had a torque wrench used on the wheels. Tire shops generally use "torque sticks" attached to impact wrenches, which are of dubious accuracy. An inexpensive beam- type torque wrench is really all you need for infrequent use. I've never carried a torque wrench in the truck. On the rare occasion you get a flat, you can can get close enough with your lug wrench until you get home or to a tire shop.
 
My HS Auto Shop instructor gave us a very clear demonstration of how you can't tighten several fasteners to the same tightness without something like a torque wrench. He had one of the Full-Backs in the class tighten a complete SBC cyl head to as best as he could make them all the same. Then the Instructor broke them loose with a student reading the beam wrench's indicator when they popped loose. His spread in torque was almost 25 ft-lbs.

What I have discovered is that you can feel pain pretty consistently. When I really need them to be close and don't have a torque wrench available I place a pinky finger where it will get squished against the wrench handle in tightening the nuts or bolts. Tighten to the same pain level. It's as accurate a wrench-less method as I've found so far. Not as good as a wrench, but way better than guessing.

Yea I agree with some of the comments above, Unless you are the cheap tire shop that uses the biggest Air Impact gun to drive your lugnuts on, you are not at risk of breaking the wheel studs. They are less critical than something like torque on a head gasket, but you want to torque them correct so you can loosen them on the side of the trail. I put anti-sieze on my studs and torque them with torque sticks. Gets them close and they come off when I need them too. I have never lost a lug nut. I would say buy a nice torque wrench you will use it for a lot of stuff, good to have in the shop for other things.
 
I use a 80 ft/lb torque stick with my M18 mid-torque impact. They work very well for wheels specifically. It's kind of a pain to manually torque all 24 lugs with a wrench. With the torque stick, you just zip them on until the lug not stops turning and you're done. I bet it saves close to 10 minutes on swapping wheels over using a manual torque wrench. I'm sure an actual torque wrench is more accurate (I have a ICON 1/2" torque wrench I use for things like axle nuts, critical suspension components, critical engine fasteners, etc), but the torque stick is accurate enough for lugs.

Torque Extensions

Proper torquing of lug nuts on wheels does more than just prevent the tire from falling off while driving down the highway. Properly torqued lug nuts are also easier to remove without damaging lugs the next time the tire needs to be serviced. Steelman’s torque extensions are specially designed...

Back when disc brakes were a new feature my grandfather had a car that the tire shop managed to cause the rotors to warp by not torquing the lug nuts. Seems pretty implausible to me, but brakes were fine driving in, and warped driving out when all that they did was replace the tires. After that he insisted on torquing the lug nuts on anything with disc brakes.

My vehicles that go into BFE get their lug nuts tightened with the exact manual tool that I would use to loosen them in the field. I also put a thin smear of marine grade anti-seize on each stud.

I keep my M18 mid-torque impact in the rig at all times, along with a backup breaker bar. It hasn't been needed yet outside of the shop, but changing a flat on the side of the road or a trail would be drastically easier with an impact.
 
I normally have the cordless impact with me, too. I plan for if I've forgotten it or the battery is dead, even though I have have one of Milwaukee's 12VDC powered M18 chargers that lives in the same bag as all of the cordless tools that go on trips and to the desert races. Each of the vehicles gets it's own one of these: Snap-on Store - https://shop.snapon.com/product/Breaker-Bars-(1-2%22)/1-2%22-Drive-24%22-Standard-Handle-Breaker-Bar/SN24C and whatever sockets & extensions are needed. Those stay in the vehicle.

I have the Harbor Freight version of that breaker bar. I think it was $13.99 :). It didn't break even with a big cheater bar on it, but it sure flexed a lot.

My M18 gets used pretty often so I make sure it has a full battery when it goes back in the rig. M18 batteries don't seem to lose much charge even when sitting around for several months.
