Manual Tire Change
Kum Verna
As soon as you realize you have a flat tire, do not abruptly brake or turn. Slowly reduce speed and scan your surroundings for a level, straight stretch of road with a wide shoulder. An empty parking lot would be an ideal place. Level ground is good because it will prevent your vehicle from rolling. Also, straight stretches of road are better than curves because oncoming traffic is more likely to see you.
Never attempt to change your tire on a narrow shoulder near oncoming traffic. Keep moving (slowly) until you find a safer spot. While driving on a flat risks ruining your rim, replacing a rim is better than being hit by an inattentive driver.
Put the lug nuts back on the lug bolts and tighten them all the way by hand. Once they are all on, check each one again, tightening as much as possible. You will tighten them with the wrench after lowering the vehicle to the ground.
I want to do so PM on the wheels, brakes, and bearings on this new 5th wheel. Not saying I don't trust the factory technician that installed the components, but I don't trust the guy that had to build and install 40 axles before he could go home.
So DRV uses the Lippert 6 pt Level up system. We are already level but I want to raise the RV so the tires are off the ground. What combo of buttons do I push? Lippert manual says to have a "Qualified" person come and change a tire..... I think I is "Qualified" to do that.....
It depends on if you want to get all the tires off the ground at once (both sides) or just one side at a time. I played around with this while the trailer was in my shop, so I wouldn't have to figure it out on the side of the road.
I do all my work myself. I raise the rear legs, then lower them so they are all planted, but the rig is not necessarily level. I then raise the side I want to work on and remove one wheel at a time, check the brakes, lube the pins and use the easy lube to pump in new grease until it comes out the front of the hub.
Turn on the system. Hit up arrow twice. Display should read manual. Hit enter. Hit left or right to raise the appropriate side. System will turn off while doing your work. Repeat the above but after hitting enter, hot retract and retract the raised side until the left to right is zero. Now hit retract again to turn it off and push the button to raise the other side. When finished repeat again all the way through retract. No need to hit auto level, it will lower the front down and re level. You can do the same with manual and it will give you practice in case it doesn't want to level sometime. Now is also a good time to put a level on your floor and reset your level up. Another note, find the large contractor. It will be by your pump motor. Familiarize yourself with it. If you are ever on a severely i level spot and can't extend your front gear enough to level, it may not allow you to retract saying "out of level". Reverse the wires on the spade connectors for the contractor. Go to the control and enter manual mode. Now push extend for the front and they will retract. Don't forget to put the wires in the proper place.
I just completed my annual bearing repack and brake inspection, along with lubing the wet bolts. Prior to lifting the rig with the hydraulic jacks, I loosened all the lug nuts, and then used the system in manual mode to raise the wheels off the ground. Once I was done, with the lug nuts firmly tight by hand, I then lowered the trailer back down, and torqued the lug nuts. I have done this every year since we have had the rig, in addition to doing tire replacements as needed. The system is great for this, even though their lawyers will say not to, but they don't even know which end of a lug wrench to hold.
MorRyde might want to add a little more grease as well. 1 axle-2 spindles, while not dry, didn't have enough grease in the bearings to wet a paper towel. They had grease, but you could handle them without getting your hands messy....
The manual says all four tires must be the same size.The spare tire must only be mounted onto the rear axle when applicable.I don't need to pull a fuse to disable AWB on my manual, but automatic transmissions do.
I talked to a tire mechanic who has been doing this for decades. He says that I do NOT have to replace all four tires with new ones. He said replacing just the single blown rear tire with a new one (same general size, but different brand and likely slightly different circumference) will be totally fine. He says he has never had any problems doing it on other Subarus. In fact, the spare tire that I was running on WAS of a different size and it ran on it just fine for 75 miles and no warning lights.
Buying four new tires may be needlessly expensive for drivers who onlyneed a single tire to join the three other moderately worn tires. Butyou can buy a single new tire from $BIG_TIRE_VENDOR and have thecompany shave it to the tread depth that matches the depth of yourother tires. It will shave any tire you buy from the company, usuallyfor $25 to $30.
Subaru's are well known for having tight tolerances on wheels. If you cannot change all four at the same time, buy a new tire of exactly the same make and model, and have the new tire shaved down to the same size as the others.
You might think that shaving a tire to be smaller is an expensive waste of money. But think of the cost of replacing your center differential (well into four figures - often cheaper to scrap the car), and it's cheap insurance.
You don't need to change all four wheels when one gets destroyed. For an emargency run you can use any wheel that fits to the hub. For a regular use I would consider the effects of mismatching tyres on the car reliability and behaviour. You can easily find that saving a buck may lead to a hundred-buck repair elsewhere.
Changing all four wheels for the very same brand, model and dimensions means that all four wheels will behave equally. The ABS wont detect different wheel speeds (no false positives detecting wheelspin/wheelslip) and viscocouples will be loaded only when their opperation os needed.
If you compare tyre radii and they match the couplers and electronics will be fine. The bigger differences in wheel dimenions, the more unnecessary load on the viscocouples and more "thinking" of ABS unit.
Different tyre models and brands behave differently and the harsher conditions the bigger the difference. Try to have same tyres on all four wheels. If not possible (financially acceptable) try to have same pairs on front and rear wheels.
To many folks, changing the tires on a vehicle means a biannual trip to the local shop to swap snow treads for some summer tires, and perhaps a jaunt or two to pick up a newly patched flat. However, as anyone living in a rural area can attest, changing punctured tires (say on that old workhorse pickup) can be a time-consuming chore when the nearest service station is a considerable distance away.
As you can see from my Assembly Diagram and List of Materials, I made my tire changer by cutting, bending, bolting, and/or welding various sizes of Schedule 40 pipe, steel plate, and flat stock. The main assembly consists of:
To put the repaired tire back on the rim, hook the curved end of the beading tool between the tire and the rim, and push down on the bead guide to pop the rubber under the rim. Then pump the good-as-new tire full of air and get ready to roll!
Tire changers are essential tools in any garage, enabling the removal and installation of tires from vehicle wheels. They come in two main types: hydraulic and manual. Each has its unique features, benefits, and challenges. But to give insights into the hydraulic vs. manual tire changer debate, here are the pros and cons of each type:
Manual tire changers are tools used to remove and install tires onto the rims of vehicle wheels. They differ significantly from their automatic or semi-automatic counterparts in their operation, requiring more physical effort and skill from the user. Understanding the pros, cons, and ideal situations for using manual tire changers can help determine when they are the best choice.
Manual tire changers consist of a stand with a clamping mechanism to hold the wheel in place and a lever-operated tool to pry the tire off the rim. These devices require the user to physically manipulate the tire and rim, using the lever to break the tire bead and then pry the tire away from the rim. The process is then reversed to install a new tire.
Hydraulic tire changers are automotive equipment designed to remove and install tires on vehicle wheels. They utilize hydraulic systems to apply controlled pressure, making changing tires more efficient and less labor-intensive than manual methods.
A hydraulic tire changer operates using a hydraulic system that generates force through the compression of fluid, typically oil. This system powers various components of the tire changer, such as the bead breaker, turntable, and mounting/demounting tool.

Whether you're a professional auto shop looking for speed and precision or a commercial enterprise needing robust and reliable equipment, JMC Equipment has the perfect solution for you.
But times have changed and it is now common practice for vehicle manufacturers to use tires significantly larger than the minimum - and the vehicle tire placard reflects that. The pressure listed on the tire does not.
Both Goodyear specs and drivegreen specs listed the above as the correct PSI rating for the corolla. I checked the Door Jamb (both sides) and it did not have the PSI ratings which is weird. It had the tire size and type but not the PSI.
Get to work. Follow the instructions in the manual, which should walk you through popping the wheel cover on the flat tire, loosening the lug nuts, jacking the vehicle, removing the flat, placing the spare, hand-tightening the lug nuts to secure the spare (do NOT use the lug wrench while the car is on the jack), lowering the vehicle, removing the jack, and using the lug wrench to tighten the lug nuts. Review what the manual says about driving on the spare.
