99spec stock wheel/tyre sizes
 

Anyone knows what is the stock size of the 99spec FD 17" wheels/tyres sizes front/rear ?

Thanks!

Front Rims: 17"x 8"JJ
Rear Rims: 17"x 8 1/2"JJ

Front Tires: 235/45/17
Rear Tires: 255/40/17

I hope that helps you out!

The sizes Rich listed are correct. I am running 245/40s instead of 235/45s in the front.
Consider the following:
US overall diameter
Front: 24.86
Rear: 24.86
Type RS
Front: 25.33
Rear: 25.03

CCarlisi spec (aka 245/40 fronts)
Front: 24.72
Rear: 25.03

Type RS & CCarlisi compared to US spec
Type RS: +.47
CCarlisi: -.14

I'm not sure why Mazda went with a 235s on the front considering they are much larger than the original fd tire setup and the 255 Type-RS rear tires.

do you have any rubbing issues up front?

None. I'm using Koni yellows with Eibach Pro-kit springs. From memory I believe the perch setting and springs together drop the ride height by just under 1 inch.

I went with the 235/45 sizing on mine. Thought about the 245/40's but wasn't sure if it would rub the fender wall.

I'm asking because in Europe we have this damn homologation issues with every change you make to the car. And since I have stock sized rubber (stock for 99spec, but I hope that counts also for previous models) there shouldn't be a problem.

Only problem is that rear rim is 9x17 and not 8.5x17.
