Hello guys,thank you all for your trying to find a right answer on my question,i will try to explain more clear,i have 18'' stock rims with 265/60/18 i would like to have wider and also bigger tires in diameter . I have found a size 285/65/18 i allready checked this size on a tire calculater, i understand that it will be different speedo reading-this is no problem i can managed it in in my ride,the more important think for me - will this tire size 285/65/18 fit to wheelwell and can be any problem if i will go with this size,if you know that this size is not good by any reason-what the biggest and widest size tire can i put on my 18'' stock rims with no worry.thank you for your help.
