Puncture-Proof Tires for Skid Steer Loaders
If you've had problems with flat tires on a skid steer loader, you'll want to take a close look at new "puncture-proof' tires made by Roger Prevost, Langham, Sask.
"Big Wheel" tires are fabricated from 3/ 8 to 1-in. thick sections of used truck tires secured to a heavy-duty oversize rim by steel cable. Each flap of tire is 12 in. by 5 in. According to Prevost, over 2 in. of rubber can be worn off before the tire needs to be replaced compared to 1/2 to 3/4 in. on a conventional tire.
"They completely eliminate flat tires and provide excellent traction on all surfaces," says Prevost. "They last longer than either conventional or foam-filled tires because the rubber is deeper and is continuous rubber all the way across, with no lugs. The result is 6 to 8 times more face wear. There are 130 to 140 individual rubber sections on each tire that are threaded together like beads on a string. They won't tear or break apart. You can make a 180 degree turn right on rebar without hurting them at all. They're widely used by foundries and metal recycling places, but they also work great when you're tearing down old buildings where there's a lot of broken cement with rebar and wood pieces sticking out. The ride is similar to a foam-filled tire."
Prevost mounts the tire sections on used truck rims that replace the 10 by 15 and 12 by 15 rims found on most skid steer loaders. "The original rims can't be used because the tire sections aren't as deep as the original tire. By using larger rims you end up with the same wheel height."
Puncture-proof tires sell for $500 each. "That sounds high but they'll last much longer than conventional tires and are trouble-free. Once a tire is worn, you can return the rim for credit on a new tire," says Prevost, who notes that he can make tires to fit any skid steer brand or model. He's looking for dealers.
