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.

 

I overpower 225 RS2s with <250 whp.

 

You are going to need some gummy *** slicks imo. That beast of yours will absolutely liquify the tires IMO.


I'd pm some of the bigger turbo guys in here over 400whp and ask them what they use.

 

I hook pretty well on 205/40/17 m/t drag radials with around 250-280ish, and my street tires are some weird brand, but they hook amazing. I'd say go for some nice 255's.

 

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.

Maybe check with the V8 swap crowd and see what's working well for them?

 

Either do drag radials, R-comps, or learn some restraint with the throttle in the first 2 or 3 gears.

 

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.

 

205 50 and 225 50 are about your only options for a 15" drag radial in any brand. i used to have some 225 50 hoosiers that hooked pretty fkn hard at the track, but they were 99% slicks no tread pattern on them at all.

 

+1 (well.. i DID, when it wasn't covered in dust sitting in my shop...)

 

245/35-17 R1Rs FTW

 

17's really are not an option on the NA the wheel is to big, not a look that I care for, though some may.

 

Have to work with what they make. I agree on the looks part, but they will fit.

 

Some 17''s look pretty decent.

 

Wheels look good, but then the brakes look small.

 

You're gonna have to comprimise somewhere. Either play with the throttle all the time like a damn supra in low gears or grow some bawlz and get some flares and tires
