Personally I don't like to lift wheels off the ground with the jacks and I would never lift the drives off the ground. If it's so unlevel that the wheels would be off the ground, I'll run up on some boards first to get close, then finish leveling with the jacks. Fronts are ok. You won’t damage anything. As stated above, never the rears (drive wheels) because the parking brakes are on the rears. If you’re not comfortable with the fronts being off the ground, you can build some small ramps or wood blocks you can drive the front wheels onto. If you search for ramps on this forum you’ll find lots of examples. When an air bag RV is lifted, ONLY the axle weight is left on the ground. no matter the lift height. This is unlike a leaf or coil spring vehicle. The tires provide limited stopping. If the leveler pads are on softer ground, they will put much restriction to the RV moving sideways as the pads will be in a hole. The suspension system has no problem handing from the shocks / limit straps. It endures FAR greater stress while you are driving down the road soaking up the bumps and road heaves. All that being said, try to NOT lift the RV any further up than is required. Things inevitably break. Hydraulic lines, solenoids, seals etc. You don't want a single leg to drop on it's own which the torques the chassis. An RV up in the air is invitation to crawl underneath or store stuff under. Not good when something breaks. So, pick a more level spot or use blocks to get the rig as level as you can before lifting. Don't park on a hill and lift so that there is no chance of slipping sideways (tire and / or leveling pad friction). Your drive axle (brakes) always have to be on the ground... else you'll go down hill as soon after you've walked bow to stern inside the coach a few times... I don't like to lift either off the ground ever. I only use the jacks enough to level the final little bit and to not have the coach shake while moving around in it. The thread Sonic posted is great! I use 2x10s like suggested in the posted link, but took it slightly further. I didn't cut an angle, don't really need it and in the past I found that it sometimes gives them the ability to slip while driving onto them. I would post pictures but it is in the shop for engine repair and the boards are in unit. Basically I took 2x10s and cut 2 boards the longest that would fit in the bay I was storing them in (about 36 inches long). I then cut 3 more boards about 8 inches shorter (for a total of 4 boards high), so lenghts of, 12, 20, 28, 36 long. I have 2 sets in case there is a need for the rear duals to go on boards. To keep the boards from sliding when driving onto them, I bought 3 different size carriage bolts that would go through 2, 3, or 4 boards but not all the way through, just long enough to keep them stable as you drive. I then took a spade bit that was 1/8 inch larger than the bolts and drilled through all 4 boards to accommodate the bolts, i did this in the rear where they would line up even and no worry about puncturing tires if they popped up slightly. I then took a spade bit slightly larger than the bolt head, and drilled on top of the holes the thickness of the bolt head. This way they sit down flush with the boards. It works very well! For the jack pads, I couldn't use anything very thick, as if I am on level ground and I dump the air, I only have about 4 inches between the jack pad and ground. I took 2x4s, and cut them the length of 3 2x4s put next to each other. I cut 6 in total. I then laid them crossways (think the first 2 layers of Jenga) and nailed them together from both sides. These work great for leveling! When i get it back from the shop next week I will try to remember to post some pictures. Your drive axle (brakes) always have to be on the ground... else you'll go down hill as soon after you've walked bow to stern inside the coach a few times...
With any wheels there is always a little trepidation about hitting larger more inanimate objects but with Sam goading me on I started to aim for rocks, ruts and tree roots (did I mention we were riding off road!!!) and in every instance the wheels soaked up the impact, leaving me free to ride the bike without worry of knackered rims, aching arms or even getting up out of the saddle to soak up the impact – you can just let the wheels do the work.

The story of loopwheels is one of determination, and a streak of madness. They were invented and developed by Sam Pearce, in his home in Nottinghamshire, England. By training and profession, Sam is a mechanical engineer and industrial designer. By nature, he is some one who loves making things: designing, building, doing. He loves simplicity, and products that work well. Sam is practical and hands-on. He is stubborn and doesn’t give up easily. All useful traits when you find you’ve set out on a journey to reinvent the wheel . . .

Premium materials, uncommon refinement and our latest technologies prevail inside TRX.
Making a bunch of assumptions about usage, you're up for a set of six of these huge hoops a year plus a spare, giving you a 10-year tire budget of around $2.66 million per truck. (These figures are adapted from the ASW company's own comparison spreadsheets, which use rubber tire pricing of $110,000 each from 2009. These tires are now much cheaper according to our research.)
Let’s put as much weight in the wheels as we can! I would just love to have to accelerate all of that weight over and over again in stop-and-go city traffic. Woof! Talk about energy savings!

To ensure that its product lived up to user standards, Softwheel turned to Dror Cohen, who became a paraplegic after a car accident in 1992. Cohen eventually became a decorated athlete, leading Israel to the gold medal in sailing (sonar class) in the 2004 Paralympics in Athens, Greece.
If you want the most functionality and lowest possible clearance, check out an air ride kit. This is one of the most sought after modifications in the lowered car community. Air suspension systems allow you to dial in your fitment perfectly and raise or lower the car from the push of a button. Air suspension kits use air pressure to adjust the height of your car on command. Speed bumps are no longer a problem!

Premium LED Smartbeam Intelligent Headlamps are integrated into widened fenders, which are flared eight inches to accommodate seven strategically placed air flow features.
Some of the most important parts of a car’s suspension system include tires, shock absorbers or struts, arms and bushings, ball joints, coil springs, and stabilizer bar link. Like most parts on the car, the shock absorbers and/or struts need to be checked regularly as part of the service schedule of the car. • Frequency of regular maintenance such as chassis lubrication and wheel alignment
Hi we are new to a air ride equipped motorhome and are wandering if it is ok to lift the wheels off the ground with the Jack's when leveling on those unlevel sites, the chassis is a Freightliner XC and it seems like the air bags are really stretched if the wheells and everything are pulling down on them in this situation ... We just do not want any damage to the system. Your input would be appreciated thanks The weight of the axle pulls down on the air bags but the weight of the front axle assembly is supported by the length of the shocks. When the shocks become fully extended, air bags, leaf or coil springs, that's when the front axle assembly quits moving down. I'm with everyone that doesn't like the looks of wheels in the air, but it doesn't hurt anything and I have done it. Think about this: The only way your motorcoach can roll away is if it's on the wheels. If it's up on the jacks, it can't roll. A good backhoe operator will hike the rear tires (where the brakes are) up in the air to get it up on the hydraulics where it is solid and stable, before operating. Sometimes they raise the front tires up with the bucket. Ever seen a mobile construction crane? First thing they do is raise all the tires up off the ground to get the unit level and stable before operating. I'm not saying to lift your coach that way, but it's not the big deal that some people try to make it sound like. On my Freightliner with the stiff rear end and V-Ride, if I lift one side a couple inches, the duals will come off the ground. Not a big deal because the jack won't roll.

Its new technology, focused around a flexible shock absorption system built into the wheel itself, allows for better stability when needed without sacrificing speed. “With all due modesty, I say that what we have created is a game changer,” said Daniel Barel, CEO of SoftWheel. “Our wheel technology can be developed for and retrofitted to any vehicle,” notably including bikes, cars and jet planes.
Currently, Loopwheels is collecting pledges on Kickstarter to raise funding. Available pledges to reserve a wheel starts at £195. Wheelchair Wheels For Sale
The most loop-the-loops in a Hot Wheels track is 10 and was achieved by Rohan Dayal and Rahul Dayal (both India) in Mumbai, Maharashtra, India, on 7 April 2021. It took Rohan and Rahul three days to build the adjustable angle wooden platform and assemble the entire track of 10 loops over it. Two people were involved in the project. Rohan Dayal and his younger brother Rahul Dayal. "Testing was initially with few loops and as we increased the loops and the length of the track, the project became challenging. Since the track became long it needed to be supported on a firmer wooden platform. The longer the platform, the greater was the weight and bending in the center. This needed strengthening of the platform. This was the initial challenge." While testing the brothers found that the journey of the car through the loops depended greatly on the angle of the platform. To facilitate variable angles they had to construct an adjustable wooden leg support. By adjusting the leg support during testing they arrived at the best angle which gave them the breakthrough that they could achieve the target. The project cost approximately INR 3500 ( approximately £35). The cost was less as the brothers already had collections of Hot Wheels cars and track and only had to purchase the remaining missing track pieces. The plywood used for the platform was upcycled from scrap. There were a numbe rof challenges faced by the pair. As the number of loops increase, the project became challenging in terms of scale. The length of the platform, it's weight, and height also presented difficulties in handling. The speed of the Hot Wheels car increases as it descends from greater heights causing the car to lose balance. Despite all these difficulties the pair think they could attempt to increase the loops by a further one or two in the future. "Since a young age of around 12 years, I would try to do small projects like making a wooden toy car or cricket bat. Later as I grew I would do some small household repair works. For all this, I would use my Dad’s tools. As a child, I liked playing with toy cars. I would make my wooden toy car and make it slide on sloping surfaces. During this time I was gifted with Hot Wheels cars and tracks which came with super smooth cars and steep sloping tracks. Soon I had a good collection of it. Recently I came to know about the Guinness World Record of 8 loops and decided that I can better the record. The Guinness World Records titleholder would be the best thing I would have ever got. It would also mean that records are an inspiration to do better and create greater records. It would be a proud moment for both me and my family."

The wheelchair application seems to run straight into the eternal problem with sprung wheels. Without dampers, they bounce badly, as sometimes seen in tractors fitted with buckets on a bad road. With dampers, they have very high rolling resistance. I tire needs enough flex to meet the ground, but any further suspension should be on the axle. Lardo January 30, 2018 06:00 PM

When you have plenty of bicycle to work with, such as is the case with a mountain bike, it’s not such a big deal to design it with front and rear suspension. When the bicycle in question is a diminutive folding city bike, however, it gets a bit trickier. That’s why UK industrial designer Sam Pearce has created Loopwheels. Instead of relying on a suspension fork and rear shock, it lets the bike’s 20-inch wheels absorb the bumps.
This illustration shows how the Loopwheel handles bumps compared to a conventional spoked wheel View gallery - 6 images

Why reinvent the wheel? Because sometimes it makes for a better bike. Loopwheels are a completely new type of bicycle wheel, designed with a unique built-in suspension that makes for a delightfully smooth ride. Instead of spokes, as on a traditional bicycle wheel, the Loopwheels have three loop-shaped springs that allow the wheel to absorb the vibrations and bumps most riders are accustomed to feeling.
