will it confuse the SHAWD if I run 17 inch snow tires for a month ,, yes i know my speed O will be off ,, I had just bought them for my 04 and they are brand new want to use them ,, I can get cheep wheels and mount them and run them for a month worth of snow . then take off .. thanks

 

no

 

Do the 17" snow tires come with TPMS sensors ?

 

Nope, this is my second winter running cheap 17s with Blizzak WS80s. The SHAWD system is fine, but the TPMS system will be slightly annoying unless you buy the sensors to put in the wheels before you mount the tires.

 

My 2013 TL SH-AWD must be insane by now.
Ya 17 inch are fine. 245/50R17 stock (non SHAWD), 245/45R18 and 245/40R19 are all the stock sizes for the TL, other options 225/55R17 or 225/50R18
Using speedometer 80MPH with 245/40R19 , 245/50R17 =actual 79.79MPH, 225/55R17 =80.08MPH, 245/45R18 = 79.8MPH and 225/50R18 =80.42MPH so all the sizes are really negligible
Heck odd ball note if you really wanted slightly better ride you could go with 255/40R19 = 80.94MPH so even that doesnt cause a measurable error. There is lots of options

 

Wondering if anyone gone with a softer tire for the winter, say a "T" speed rated tire mounted on a SH-AWD? Thinking of downsizing to 225/55R17 for the winter, and looking for members who have went with that speed rating and how it performs. I'm in the snow belt.

 

I am using H Michelin X-Ice Xi3 225/55 17 and there were plenty of T listed. The load index was well within the range 1609x4 on T ones. How often would I ever get up 118mph in the winter. Most I have done is like 85ish on SD interstates.

 

Last year i was using Dunlop Graspic DS-3 225/55/17 97Q. "Q" speed rating was ok and i tought that 97 load index was right. But I HATED driving with those tires. I don't know if those tires are just a bad fit for the car but the car would just kept going straight instead of turning in curve. Felt like the sidewall wasnt hard enough. BTW I live in Quebec city and we have harsh winter conditions here shit ton of snow and temp can go as low as -22F or -30C sometimes. Wonder if anyone ever had those tires before but i'm going back to either the blizzak's ws80, Michelin x ice or the nokian hakka with 101xl load index.

P.S: my TL is awd
