We are considering running Nitto NT-01's on our ITA Honda Civic Si. We have run a couple of races at Hallett and are just learning. The tires that we have run have been used tires that came with the car when we bought it. We had a set of pretty worn Toyo RA1's that we corded by locking it up. Then we have 2 sets of pretty worn R6's, so we have never had a new set of tires to compare anything to. We are looking for a tire that is going to last and is affordable. We want seat time so we can become consistent then worry about speed later. I figure any new tire will be as fast as the worn out tires we have been running. From what I have read you don't have to shave the Nitto's like the RA1's. I can get a set of Nitto's from Discount Tire Direct for $496 shipped. Has anyone run these tires? I would like to hear some feedback before we pull the trigger and order a set. Give me your opinions please.
