I have 2 sets of wheels, my summer (non-winter) wheels are 245/45 R18 & my winter set is stock 225/55 R17 on the 17" I have TOYO CELSIUS tires technically they are all-season but I only run them from like December- March/April depending.
My question is , im replacing 1 pair & im looking for comments/suggestions/advice on whether I should put the brand new Toyo's on the front ,for steering control or if I would be better off putting the new full tread toyos on the rear axle for traction. I've asked many tire professionals and it seems to be a matter of personal preference. Some recommend putting the new tires on the front to increase handling/steering in snow. While others have recommended putting them on the rear. FYI last year's set were still good , about 60-70 % tread left on them, but i wanted some fresh tires for the winter. I know the G35x is only AWD till a certain speed then is primarily RWD. So idk which I would get a greater benefit from. FRONT or REAR.

Appreciate any advice! Thank you.

 

Your BEST winter tires should always be on the rear of the car (regardless of RWD, FWD, AWD, 4WD). Putting them on the front increases your likelihood of spinning the car out in a corner because the front will grip and the tail will swing out.

This used to be a common well-known fact from back in the day with industry dominant RWD and tire chains. It's sort of been forgotten with the FWD revolution and people always chaining up all 4 wheels now. FWD requires chains on each corner, RWD used to only REQUIRE chains on the rear (but better if you did all four corners).

 

Rear since it's a RWD biased system
