Hi all

Can you advise if it's possible to replace the 255/40/20 tires in the front of my Porsche Panamera Turbo 2010 (Turbo II rims) with 285/35/20 ? I have a spare set of these tires that I would like to change to this car from my GTR

Thanks

DD

Hmm height difference is - 0.6 percent . Should be OK then ?

 

In this case you should consider only about width.
