Hi, I'm female and after three weeks of trying frustrated as hell. Im looking for tires that are good in snow but cant afford dedicated ones and I did a ton of homework. Seems every decent tire doesnt come in my size door sais 215 75 15, websites say 225 70 15. What do I have to do? Do I need to change rims (id be junkyarding it) and to what? is there another answer? pleas ehelp. thanks.
