Title: rear tyre size
Post by: mickeyfish on October 9, 2015, 23:43
I have 195/55/r15s all round. Would fitting 215s on the rear do the job.

Sounds like a good idea. 195 and 215 is the correct stagger I believe

called a local tyre fitters this morning. he recommend, 215/45/r15...or 205/50/r15. does that sound about right?.  not had the car long, don't know a lot about em. got new alloys on because the stock ones were knackered. they fitted 195/55/15 all round. seems to drive ok to me, although I never go too fast, ( so peeps can see my lovely little car). now I am concerned that something is wrong with the wheel/tyre combination. when I look on't tinterweb,,all I get is confused........what tyres can I put on the back to make my baby better.

The phenomenon you speak of is tyre stagger;

The fronts are narrower than the rears. This is done from new manufacture to promote understeer in the car for a safety feature - understeer is considered safer and easier to understand by average joe, than oversteer.

A lot of people try to keep the correct stagger, so if they move up to 195s on the front, they go to 215 on the rear.

If you only "cruise around" I'm sure you will never notice a difference with the same size all round.

If you are concerned about the balance then go to 215 on the rear and ensure the profile section is correct to keep the same rolling radius
