I have a couple sets of R14's for my current car which is R14. Are there any general rules as to how close the size dimensions have to be to my old tires (the ones I'm currently using) in order for them to fit nice and snug on my rims? Or can the garage just stretch any size as long as its R14?

Any help is appreciated boys, thanks.

width and sidewall height can change still.

the big number if the width of the tire tread and the small number if the sidewall height

xxx/xx/xx

width,sidewall,size

idk what you're asking

he wants to stances his r14's. Wants to get that super stretch going on

My question is can the width and sidewall measurements be off by a bit and the tire still fit the rim?

Or does the xxx/xx have to be exactly the same despite both being R14's

what size do you have now?
and what size are you trying to put on?

You are limited by the size that will clear the fenders on the car and by the width of the rim.
