Tyres-225/45/17 instead of 225/50/17 ??? - Vx-Mad-G - 14:th-Oct-2018
Hi all,
I need to change my tyres and thinking of whacking on some winters over the next few months.
Thing is, the 225/50/17 seems such an expensive size.
Can I change it to 225/45/17..?
If so, any impact to the car, drivability, stability, etc?
It's a 2011, 2.0 Diesel 5 door.
Thanks

I would be more stable
But you would loose a bit of driving comfort and you would make astras already big space between tire and fender more bigger

Based on data from the web the original tyres are 215/50R17.
Small differences and like Jopo2311 mentioned impact on driving comfort.
Some numbers:
Circumference (2032 mm - 1993 mm)
Revs per mile (792 - 808)

I made a saving of around £15 a corner by simply just changing the speed rating from a 94V to a 94Y when I got new Bridgestone RE050A 250/50/17's recently.
Apparently a Y rating is more common, so it's cheaper than a V rated tyre.
You can go up in a speed rating, but not down from the recommended value.

personally, i would stick with a 50 profile, i had 45 profile on an Astra coupe and took it up to 50, far more comfortable on British pothole ridden roads.

Thanks guys, im going to stick with the 50's.
They are so flipping expensive. Anyone got a spare set, LOL!.
