Use what ever brand you wish...I run Maxxis in the ST configuration with good luck in an E rated tire. Others have had good luck with other brands. All the brands started out new at some point. I like the idea of a higher speed rating even though Maxxis says theirs are tested to 75mph they have to rate them at 65 due to legal agreements. I also like Discount Tire as I've purchased all my tires there and believe they know what they are talking about. Maybe a new competitor would be good for the market!
