currently got 205/50/15s on my SSRs they need replacing not entirly sure wether to go for 195s or 205s

is there any benefits to either? i dont know a great deal about tyres

edit they are 15*7 et 26

195/50 without a shadow of doubt imo.

- Correct rolling radius (205/50 would be bigger overall diameter making your speedo underread even more)
- Cheaper
- Better look on a 7"

sorry if i'm being dim

but wouldn't 205/50/15 and 195/50/15 have the same radius as the only difference it tyre width ????

 

[Andy-H]

no the rolling radius is slightly different

195 =11.3 inch
205= 11.5 inch

as we fellows know .2 of an inch is a hell of a lot

In each case the 50 means the sidewall height is 50% of the tread width, so 50% of 195 on a 195/50 and 50% of 205 on a 205/50.

Why?..... The actual gain in the contact patch is 1 or 2mm, it's an utter wast of money.
