997 s rear tyres

[dickyf]

does anyone know if there would be any issues in fitting slighly wider tyres to the rears. 305's rater than 295's?
thanks

Ive been down this road..the 997 2s came with 295 thats the deal. The 4s on the otherhand came with 305 and I think the gt3.
Its not the way to go..295 if its a 2s.
Hope this helps

2S runs 295 and 4S runs 305.

Why would you want to change up to 305? Don't see the point.

reason for the question- simply i have a spare pair of new 305s.

Would you buy a pair of size ten shoes if you are in a nine?..

Put them on.... Wont make a blind bit of difference.

thanks for the comments/opinions, i really wanted to know if there were any specific issues why i should NOT fit them, would it effect my insurance in the event of an accident having tyres not to the manufactures specification~?
and what about technically, the rolling circumference remains the same but would the additional grip offered alter handling/psm etc etc.
or is it so incidental it doesn't make a scrap of difference?

It will make a difference..the car was mwant to have 295 not 305. It is more than likely that you will get the psm light flashing..the car is set up to run 295 and thats it. No doubt you could run 310 but they will still be the wrong tyre for the car.

I'm not sure it will make a noticeable difference, but I certainly wouldn't do it without written confirmation from my insurance company that they were happy with this approach, and that I was fully covered............
