Tires and big horse power
A few of you know my build and have been following it over in the build section.
For those that don't, I have a '91 that I have swapped a honda s2000 drive train into. I am now in the process of turbocharging the car. Depending on the boost I will have between 350 and 450 rwhp.
I am trying to work out a tire selection for my project. I would like to run 6ul wheels, the question is 8" or 9" I have 225/45/15 rs3 tires sitting in my garage, my tuner kind of laughed at me when I told him what I wanted to run for tires. He thinks that I will easily over power this little amount of tire.
So the question is what should I run for tire? I would love to keep the car stock in appearance (no flares) as I may be moving the entire conversion into a 99 in about a year. I know that 9" wheels are going to require rolling the fenders and a small pull for clearance. Not sure I want to do this either, but may not have a choice.
If I decide to keep the NA what are the best flare choices? I am thinking something along the line of tuckin 99's or autokonexion flares. If I go to a NB body what kind of rubber could I fit.
Please keep in mind that this car is not a track weapon so I need tires that are designed for street use. I have a SM that I drive on the track. It will see the track on rare occasion but only for 3 or 4 laps at a time.
Any input is greatly appreciated.

For street tires, there isnt much above a 225 until you get to 17" wheels.
Not optimal for miata at all, but there isnt much demand for anything like a 255/35/15 for someone to make and make a reasonable profit off of.

Yeah, not quite sure what I am going to do about traction. I will be running 3.636 gears but that is not going to help much.
As I said I am thinking about moving the swap to a 99. Has anyone put 17's under big flares? Anyone have any pictures?

Start looking at the tire compound, size means very little if it isn't sticky.

Yep I know that, just trying to figure out what the other guys are running.
I know that I am going to have to practice throttle modulation in order to get the car to hook. It will definitely be a learning experience.

I am going with 225/45/15 RS3's on 15x8 6UL's (just decided this) for DD tires. Had them on the turbo car and they were fine. I also picked up an additional pair of 15x8's and will be adding a pair of Mickey Thompson ET Street Drag Radials for maximum stick when I want to go fast in a straight line. I know that some of the V8 Miata guys run the ET Streets full time on the rear. They are only available in 225/50/15, though.
I will be in the low 300's WHP, 320-330 TQ on my V8 Miata.

The 15x8 is how I was leaning, as they wont require any massaging of the body. I was throwing out some different scenarios to see what others thought; sometimes it helps to get others perspectives and inputs.
As far as the MT's go, Im not sure I want to run a 225/50. Although the traction would be nice, I don't think I want that much side wall.
