Great Tire!, July 20, 2009
By Lifes2eze from Celina, TX

"If you've ever tried airing up a pneumatic tire of this size or even attempting to get a flat tire fixed, you will definitely appreciate this tire. I purchased two of them for my zero turn radius mower and couldn't be more pleased. These tires should last a lifetime or certainly the life of the mower."

GRIEF-NO-MORE, August 19, 2008
By BIGJACKJOE from FOLEY ALABAMA (NEAR GULF SHORES)

"I FINALLY HAVE A SET OF WHEELS FOR MY 72" FINISHING MOWER THAT DO NOT BEG FOR ATTENTION EVERY TIME THE GRASS IS CUT. THANK YOU NORTHERN TOOLS AND NEW TECHNOLOGY FOR 'NO FLAT WHEELS'. FOR 10 YEARS I HAVE HAD TO MAINTAIN A CLOSE EYE ON THE STATUS OF THE TIRES AND WHEELS BECAUSE OF THE IMPORTANCE OF HEIGHT LEVEL OF THE CUTTING BLADES. AT LEAST ONE OR MORE OF THE TIRES NEEDED TO BE REPAIRED OR AIR PUMPED IN SEVERAL TIMES DURING THE SUMMER SEASON, BUT NOW NONE OF THAT IS NECESSARY. WHAT A GREAT FEELING, NOW JUST A QUICK LOOK AT THE 4 TIRES LETS ME KNOW ALL IS WELL BEFORE I CRANK THINGS UP. HEY GUYS-- IF YOUR TIRE OR WHEEL ATTENTION IS MORE THAN 4-5 SECONDS LIKE I HAD, DO THE SMART THING AND GET THE 'NO FLATS'. I SHOULD HAVE DONE THAT YEARS AGO........ BUT AM SO GLAD NOW I DID...
YOU CAN THANK ME LATER.
BJJ."

Flat-Free Wheels, August 11, 2008
By Anonymous from Franklin, TN

"These tires have saved me too many times. They ride like neumatic but will hold up to anything. If you're running air tires it is just a matter of time. I had to choose between this and slime and I'll tell you that the slime was a real mess."

hub inside surface not uniform, May 10, 2008
By peter495 from Farmington, Connecticut

"Wheel was purchased as replacement for Snapper Pro-Express lawnmower caster wheel. A weld running along the inside of the hub impedes roller bearing action. I scrapped the idea of using the wheel and bought a replace Skag wheel at my local lawnmower store. Before you can use this wheel with roller bearings, you will need to fix the hub's inside surface."

Marathon Run Flat - 9 x 3.5 - 4in., January 15, 2008
By Martin2112 from Pittsburgh, PA

"Great replacement for tires on my 6' finish mower...which inevitably ends up
mowing a little small brush (and causing a flat) because I'm too lazy to change
to my brush hog. I couldn't justify the high price for OEM run flat tires & searched
everywhere for the right size. Now I can mow all season long with no hassles...other than greasing all the fittings on the mower...thanks Northern!!"

Flat Free wheels, October 8, 2007
By dbar2ranch from Choctaw, OK

"The wheels work very good on my finish mower. King Kutter mower tires are very difficult to maintain. I have had to replace them numerous times. These tires will eliminate that problem and cost."
