Mr.Magneto

Winter is coming and I'd like to drive my 2016 Cayman in freezing temps - but Summer tires really won't allow.. This car has 19" wheels...
I've seen some UHP tires that would be 10mm wider (235>245)in front and the same in the back (265>275)..
Given sensors, etc..is this going to cause a problem with simply having a wider tire?
Going to a tire/wheel calculator shows only a single digit change in %..
Has anybody else done this? If so, any issues?

Thanks in advance!

The general wisdom is to use NARROWER tires for Snow use -- more weight per area than with wider tires.

10 mm you should be fine.....i hope they are a real good snow tire cuz mine goes nowhere in the snow with regular tires

Mr.Magneto

Thanks much for the replies!
The issue isn't snow as it is subfreezing temps.. Just didn't want to drive Summer tires with temperatures below freezing..

In my experience in the Northeast where the winters are cold, even the summer tires are fine for street use in the cold -- but they are absolutely unusable in ANY snow.

I use to say that my P-car wouldn't move an inch if there was a flake of snow anywhere in the county.

If you're not worried about snow traction, 10mm wider won't hurt anything when using the same wheels - that's 5mm per side wider (less than half the size of your fingernail).

For snow traction, obviously skinnier is better (wider tires gives a snow shoe effect, where it more easily stays on top of the snow rather than penetrate towards the street).
Of course, anything is better than summer tires which are the equivalent of driving on hockey pucks.
