The 305/30-19 is a popular size. I run it on all 4 corners for the track.
And there seems like a fair amount of guys who run the 18" wheels so they can run the Pirelli DH scrubs.

The wider 305/30 will present challenges when it comes to tire to strut clearance when using aggressive camber settings. But with the correct offset, this is not a problem. But, when you do have a proper offset for tire to strut clearance then the tire starts to poke out a bit at the fender. Camber plates help all of that.

The use of an 18" brings the clearance issue to the wheel and not the tire because, depending on offset and camber setting, the wheel is going to hit the top of the knuckle first. The knuckle can be ground down for clearance.

The only tires I've run on track are the:
-Gen5 SS 1LE OE tire Goodyear F1 SuperCar G:2
-Bridgestone RE71R
-Michelin Pilot Sport Cup 2
-Goodyear F1 SuperCar 3R
I have been running the 3R for almost 4 years now.


The Goodyear SuperCar 3 is a great tire. I say that without having run them on track the (yet), but I've driven them on the street. So take that for what it is worth. haha. But the Gen6 SS 1LE and ZL1 both run them and are fantastic track cars and the feedback from others confirms that they are very good on other models. One of my track buddies had a Gen6 SS with the 3's and he laid down some amazing times with them. They have great potential in the right hands. But be prepared, there's always a trade off for grip. Wet performance and longevity. But since these are going to be a track only set of tires, then it doesn't matter.

The Michelin 4S does not have the same dry grip as the SuperCar3 but it does better in the wet, cooler temps and longevity.

As a novice, you're better off with a less grippy tire. Going to something like the DH scrubs or the 3R would not be good for a novice. I think the SuperCar 3 would be a good choice. But that would be at the upper end of the tire choice spectrum for a novice. Realistically, tire choice for a novice is pretty wide. A novice will have a lot of other things to be concerned about other than getting the most out of a tire.

And yes, the Road Course/Track and AutoX subforums would be a better place for your question.
