We cannot remove any of the tires on our 2005 chevy silverado. we have removed the lug nuts but the tires will not come off. is there some trick to this?

What are you trying to remove the spare tire from? Is it mounted on the axle? If you removed the lug nuts and it seems like its glued to the rotor, put the lug nuts back in about 3/4 of the way, then lower the jack to put come pressure on the wheel, roll back and forth a bit if needed and your wheels will likely break free. Sometimes corrosion makes the wheel stick. Good luck!

get a BIG hammer and try striking tire (NOT RIM) USE SOME LUBE SPRAY

Hi, the spare tire is stored on the underside of the vehicle, under the right-side cargo door. The bolt is located in a recessed area that is protected by a small square plastic covering. To remove the spare tire, find and remove the bolt cover, then use your lug nut wrench to loosen the bolt holding the tire.
Remove the spare tire fastener's plastic cover, place the lug nut wrench onto the lug nut holding the tire onto the bolt, turn the wrench in a counter-clockwise direction until the tire is released and reaches the ground.

mcdevito75 here, They should be knockoffs, That castle nut is holding the hub / Bearing assembly to the axle, and once removed that nut has to be replaced with a new one, so it"s not reasonable that nut has to come off to get the rotors off. Try, remove the tire and lift the caliper assembly off the rotor, use penetrating oil, liquid wrench, W D 40 around the lugs as they may be part of the rotor assembly, Then with a hammer tap moderately around the edge of the rotor to loosen it, keep the gear in Neautrel so you can turn the rotor while tapping with the hammer and use that penetrating oil around the lug studs and around the hub. The rotor should fit around the hub where that nut is and thru the lug studs that hold the tire on the axle.

it seized on the hub is all. lay on side, kick with the back of you heel without laying under vehicle. thread on a lug a few turns so it doesnt take off. be carful! make sure its hoisted safely with a block or stand for back up

Generally, if the hub cap does not have what appear to be lug nuts, there should be a **** big enough to put a flat head screwdriver or a tire iron into and just pry it gently open.

Once All of the lug nuts are removed from the studs, if the vehicle is jacked up off of the ground, clearance under the tire, pull the tire off, it will be pretty heavy.

Aha! Here is what you do. Leave one lug nut loose on the wheel and remove the rest. With the vehicle on a jackstand and secure, sit down facing the wheel and kick the bottom of the wheel really hard, repeat if necessary. This always does the trick! Must be a rear wheel? The rim gets stuck to the brake drum from rust all of the time!
Don't forget to rate this solution, and good luck!

the plastic nut doesnt actually come all the way off. it just stays with the center. and once you get these undone you can then pull the cover off

use 3lb sledge on inner edge of rim be careful not to damage rim rubber mallet won't provide enough shock to loosen rust. ps leave one lug nut on so tire won't fly off.
