Wheels and Tires

What are the disadvantages of driving winter tires in 70+ temperatures (trips from NJ to Gulf Coast in mid January)?

I have a '18 Cayman with 19" wheels and want to buy smaller (narrower?) rims for winter tire set up. Will older Cayman or Boxster rims fit my car? I want to keep the spedo working properly & the TPMS too.

I replace my wheels n tires to 235/35/19 front, 275/30/19 from 235/40/18, 265/40/18 it is possible to change to 245/35/18 front, 295/30/19 rear, it will efffect the performance

I recentle rinstall my wheels tires to 19 inch staggered, 235/35/19 front; 275/30/19 rear with 5mm n 15 mm spacers front n back, while driving my steering shimming n vibtrating to much in high speed sometimes driving on flat surface moderate shaking.. What could be the reasons n how can I resolve or fix the problems

No matter how much I scrub and no matter what solution I use, my tires still have a brown coating after washing.  How can I clean my tires?

My car is a standard 2016 Cayman 6 speed with 19 inch wheels.  

I just purchased a 2014 Cayman S from a dealer 70 miles from home. Will I cause damage to the summer tires if I drive it home when the temperature is below 40 degrees, and how much traction loss will I have ?  I do not plan to drive it in winter.

Please advise best tires for my Cayman S for daily driving.

I just bought a 718 Cayman S.  It came with 20" wheels (8" wide in front and 10" wide in rear.)  Friends and enthusiasts are telling me I need to get a second set of wheels to be able to have tires for the track and tires for everyday and winter.  I found a set on the PCA classifieds but the rear wheels are 11" rims.  My car came with 10" rims.   Does anyone know if I can put the 11" rims on my car?  The offset is different so it seems most of the extra inch will be inward, not outward.

Hi

Looking for advice on replacing brake pads and tires

I bought a 2009 Cayman (base) in June 2016 with 36K miles.

i have added 4K miles in the last year, some of it on DE days and autocross.  The pads will need replacement soon and the tires later.  I believe I have OE pads and OE drilled rotors.  Rotors look good to my untrained eye.

I am looking for a compromise street and track pads and tires.  I am not interested in changing out pads or tires for an event.
