Would these GTC wheels on my Sedan cause any problems?

[astra777]

Hey everyone.

I own a 2015 Opel Astra Sedan (1.6 CDTi 136PS)

I found 8.5x20 wheels from a wrecked Astra J GTC. I wanna change my OEM 7x17s (225/50 R17) to those.

They both have same bolt patterns (5x115)

Would that change cause any issues (to speedometer, ABS, traction control etc)? Because general fact is more than +3% increase  is not recommended and It's about +6.9% change to the tire size.

But they're also Astra wheels so I'm confused about what should I do.

I'm thinking to get brand new 245/40 R20 tires if you guys approve the purchase.

What should I do? Thanks in advance.

Someone did a copy and paste should be able to see it now.
