225/45R18 on MS3 stock rims?

[elkspit]

Is anyone running these on the MS3 2008-2009? Tirerack says I might need to roll fenders to run this size.

[horto]

should be fine without a roll.

Is kinda fat....but should be fine if the car is not lowered.

i ran this exact combo for a year with no issues on the daily drive.

anyone know if this is okay to run on a 2010 mazdaspeed? or will it throw the speedometer off?

thanks

if you change sidewall height im 99.99% sure the the change in diameter will throw the speedo off,

but im sure someone will chime in a smash this common sense reply :P

It will throw your speedo off a bit. Better to get a 225/40R18 if you can.
