My 2002 Santa Fe takes P225/70 R16 Tires. 70 represents the depth of the tire..i.e. 70% of the 225cm But other than Hyundai, most places, i.e. Wal-Mart,Canadian Tire do not carry 225/70 You can get 225/60 or 225/75 My Question: Is it okay to go with an option other than 225/70 from a safety standpoint? I know Hyundai will say "warranty yadda,yadda", but my warranty is long gone Thanks
