Any issues with 225/50/17 vs 245/40/18

[Upex]

Hi all,

Hope you're well.

Wonder if there any issues with using 225/50/17 inplace of current 245/40/18

Think the former are on 7inch rims and the latter 8inch rims.

Need a spare set of wheels & tyres to use whilst get mine refurbished and then perhaps as winter set. The 17s are local and decent price off a Honda, so would need spigot rings but offset and pcd ok.

Car is a gs450h 2006, any reason (like weight vs width) that the 17s 7inch 225s wouldn't be suitable?

Thanks all
