i used to own 2 s2k's in the past and never had either long enough to change tires im in a boosted miata now and am looking to buy snow tires the size for my car is

185/60-14

the blizzaks he has are

185/60R-14

what does the R means are they the same tire?

 

I think it means radial.

 

R" means the rim size. for example 255/40r17

 

Not a dumb question, hey we all start somewhere.
