looking for a link to a site that crossreferences tire interchange IE: if factory is this, then +1 is this, +2 is this, etc.

Going to put 15's on the '92, but want to maintain stock diameter. Sticker calls for a 185/75-14, which should +1 to a 195/70-15 or +2 to a 205/65-15, right?

If you go on sites like discount tire and tire rack. Look at the plus size tires it will tell you.

Tire calculators are also helpful:

cool that's what I was looking for, thanks.
