I was going 125mph on Goodyear Regatta 2\'s. Ride was super smooth too! Had 2 people sleeping in the back, lol
The tire tread and model is more important than the speed rating. Most enthusiasts go for Z-rated tires if they like to push the limits of their car. If you want better traction look at the sports/performance models of Michelin/BFG/Yoko/Toyo/ etc... While you\'ll get more rubber on the road you\'ll lose the full diameter grooves for traction in the rain. Worth it if you\'re a safe driver imo..
