Review on Upgrade Your Skating Experience With Rollerex VXT500 Inline Skate Wheels - Available In Various Sizes And Colors For Indoor And Outdoor Use by Matthew Flores

My 150 pound, hard skating son has gotten many hours of skating on very rough pavement so far. He does rotate the wheels to wear them evenly. These have been holding up as well as some higher priced 84A wheels that we have tried in the past. He says they have good grip and are comfortable, not too hard. They definitely won't last as some 89A that we found for a good price but they are a very good value to be sure. Compared to the 78A that have come on the last pair of skates we got him these will literally last 4 times as long. He wore those out in a couple weeks the way he skates.nearly daily for hours. It looks like these certainly could make it 2 months maybe more. It's hard to find good information about how long wheels will last.so I hope this helps someone. My son is over 150 lbs., skates pretty aggressively.not tricks just forward and backward skating, hours at a time at least 4 days a week on average. 30-40 hours per month. Basically all rough asphalt and concrete. He didn't get half that many hours out of the wheels that came with the skates.these might last for 60-70 hours before he really needs to change them.
