Mixing Tire Sizes (Winter Rubber)
My FWD Chevy currently has 225x50R-17 Blizzak winter tires on the front for winter driving. I've been running these tires on the front with a pair of the original all seasons on the rear for a few years and they've worked fine. A new pair (2) of exactly the same Blizzak winter tire make and model have been offerred to me at no cost but they are 235x45R-17s so they're a little wider and a bit lower profile than the front set. Replacing the two rear all seasons with these Blizzaks will give me much improved rear traction, but I'm not sure how it would affect the vehicles handling with different sized tires front and back. I realize the ideal situation would be to have all four tires the same size but these tires are real costly so if I can use the new ones offerred to me for free I'd like to... but not if it seriously compromises handling and therefore safety. Any thoughts on this fellas?
