Mazda, Cx-9 gs
Hi, I am looking to buy some winter tires for my 2018 Mazda Cx-9. The stock tire size is 255 60 r18, anyone knows if some 17 inches tires would fit?


Thanks
 
245/65-17 works fine. The outside diameter is within 2% of the original size, so that's OK. The load capacity is OK. The width is OK (not wider which may rub).

For wheels, keep in mind the various parameters...lug pattern, lug bolt circle, centerbore diameter (add spacer if too big), rim offset, rim width (to fit the tires of choice), load capacity. There's the x-factor...will it clear the brake calipers? You might need new lug nuts if the wheel seat is different. I have some 17" Kia wheels that fit fine.
