As regards maxxis the , cheerleaders have chosen to ignore the facts .
Consumer Reports Passenger Tire tests reveal that no maxxis has scored above the Lowest 25 % of their ratings .
Maxxis tires have been reported 19 times on this forum for failures .
Considering that Goodyear and Carlisle ship OEM and have had the longest running widest distribution network for ST tires , that means that only a percentage of ST tires in use are Maxxis .
The Maxxis tires have had at least the same failure rate as the leading brands .
The real solution to tire failures is to upgrade to a higher weight rating in pounds as shown on the sidewall of every tire .
The brand is not as significant unless you pay for the best brands which are repeatedly Michelin , Continental , Bridegstone etc.
