But after a few rocky encounters, he decided there had to be a better way to maneuver over rough terrain in a wheelchair. So he did what anyone with experience in mechanics would do – he made a new wheel.
I used to think that URT suspension and suspended seatposts were the worst ways to implement suspension on a bicycle. gringo on April 15th, 2013 - 3:10am

"If I had a preference," says Ina Ames, owner of Rim and Wheel Works in Waltham, "I'd avoid anything with a wheel diameter larger than 18 inches. Once you hit 18 inches, straightening becomes much more difficult. In the Greater Boston area, if you're driving cars with 19- or 20-inch wheels, you're just begging to come into my shop."

In a Globe story this February, reporter Eric Moskowitz noted that Boston fills approximately 19,000 potholes in an average winter, and that the city has gone as far as developing a new app, called Street Bump, that attempts to give drivers the ability to instantly notify City Hall when a new crater appears. And that's just the city of Boston. Do the math and consider how many gaping holes have appeared in the New England region after last winter's prodigious snowfall.

Repairs aren't the only pricey setback, When it comes time to replace a high-performance, low-profile tire, the cost can be staggering. Take, for example, the 2011 Chrysler 300C AWD. By the time 35,000 miles pass, according to TireRack.com, you'll be looking at an $1,128 bill if you opt for the factory Michelin Pilot HX MXM4 tires in 235/55R19 size, not including mount, balance, tire disposal, or the four-wheel alignment that's always a good idea before investing in new rubber.

Wheelchair design has evolved in recent years but users can still find it demanding to propel themselves. That can be especially difficult and uncomfortable on rough surfaces such as cobbles and paving stones.
When installing the wheels, lugs should be hand-torqued in a star pattern and not installed using an impact tool.
With boulders in your sights, TRX shifts to an extra low gear ratio and uses a 50/50 torque split. Plus, a Selec-Speed® Control holds a set velocity for a controlled descent.
A set of ASW wheels, on the other hand, will cost you more upfront but last something like 13 times longer – out to the service life of the truck itself. Your first set of six wheels in this case will run you about $1.705 million, but over 10 years you'll likely only need two tread replacements at around $55,000 a pop, giving you a 10-year budget of $1.815 million and a $845,000 saving.
The suspension effect also makes it much easier for a wheelchair user to negotiate steep curbs, both nosing down and backing up, as the suspension effect takes much of the steepness out of the exercise.
