Urgent trackday tyre advice needed

[Gary H]

Hi - I need to get some tyres for a weekend at the Nurburgring and Spa this weekend and have just been told that my preferred tyres are out of stock in the standard sizes.

I'm running a pair of 987 17's (6.5's and 8.5's IIRC) and was going for a pair of 205/50's and 255/40'17's.

I've been offered the following:

Option 1:

215/45/17 & 235/45/17

Option 2:

225/45/17 & 245/40/17


My only concerns are: will a 235 be too narrow for the rear - and will a 225 be too wide for the front?

I need to do something today, so any help appreciated.
