Need a new set of D/R and really like the M/T drag radials but want them to last Ive had the Nittos and the BFG which suck if the track isnt prepped. Best 60' on the BFG was 1.72 but I may go back to them ,my car is driven once a week to shows or dinner and the track once a year . Just dont want to buy the M/Ts and have them wear out in a few miles. So what kinda miles should I expect with normal diving and the occasional street race?
