Question Fitting 225 45 17 Tyres to WRX?

Can you fit 225 45 17 tyres to the fronts while running 215 45 17's on the rears?

Some for sale locally at a very good price but will give a miss if any issues.

I think the bigger tyre has to be fitted to the rear by law.

If they're a good price,buy them,then try and get another pair,then change all four at the same time

the 45 profile part is the aspect ratio of the tyre,
Alot of people think that this means 45mm, it does not,
Its 45% of the tyres section width i.e the 215 part (which is in mm)

If you fit 215/45 on the front and 225/45 on the rear,
your likely to cause damage the the transfer box and difs due to the rolling radius being different,

don't do it in other words lol

If the 225's were half worn and the 215's brand new you might have got away with it, but not recommended.

P.S. I tried 215/235 on mine and I could feel the centre diff complaining on the 3 mile run to work.... I cycled next day, till Camskill delivered two more tyres.

I would think its going to mess up the diff and wouldnt take the risk with a performance car.
