Tyre calculation for your 206

Recently due to alot of 206 owners who wishes to change thier stock tyre or rims to a better or performance type but didnt know what size of the tyre they should go for. Ive listed some info for your referrence.

Here are some list of difference rims and tyre comparing with the stock set. What most importantly in looking for the right size of the tyre/rims is, to keep the speedometer reading as close as possible to the original stock.

Please be aware that for 1.4L the best size is to go for a 15" rims. For max. size it is 16" (which will void your warranty, unless it was from NZ Galaxy)


Stock : 175/65/14

For 14" rims

Tyre 1: 175/65/14 (Best size)
Speedometer reading : 0.0% too fast
( speedometer reading at 60kmph, actual speed 60kmph)
Tyre 2: 185/60/14
Speedometer reading : 0.9% too fast
( speedometer reading at 60kmph, actual speed 59.4kmph)

For 15" rims

Tyre 1: 185/55/15 (Best size)

Speedometer reading : 0.2% too slow
( speedometer reading at 60kmph, actual speed 60.1kmph)
Tyre 2: 195/50/15
Speedometer reading : 1.2% too fast
( speedometer reading at 60kmph, actual speed 59.3kmph)
Tyre 3: 205/50/15
Speedometer reading : 0.5% too slow
( speedometer reading at 60kmph, actual speed 60.3kmph)

For 16" rims

Tyre 1: 205/45/16
Speedometer reading : 1.3% too slow
( speedometer reading at 60kmph, actual speed 60.8kmph)
Tyre 2: 215/40/16
Speedometer reading : 0.8% too fast
( speedometer reading at 60kmph, actual speed 59.5kmph)
Tyre 3: 225/40/16 (Best size)
Speedometer reading : 0.6% too slow
( speedometer reading at 60kmph, actual speed 60.3kmph)


Hope this will give you some idea when selecting a tyre size for your new rims or just wanted to try a difference size tyre on the stock rims.

Hey Eugene, this is a good compilation.

One thing though, I am not sure if Naza has calibrated the speedometer when they "changed" the stock tires from 185/65 to 175/65 in the 206 Bestari.

If they have, they your calculations are correct. But if they have not calibrated (as they may have thought the 0.9% difference is too small), then it's another story lor.

By the way, you have left out 195/55/15. I think that's one suitable size too.

Ethan,

195/55/15 is out by 2.1% too slow.. so at 60kmph u are goin at 61.3kmph

i am trying to get below 2.0% but as you said dunno naza had calibrated the speedometer or not.. its hard to tell.. i think the 175/65/14 is supposely to be on a 1.1L 206.

Hi, I'm just a random peugeot 206 owner who doesn't know what his tire pressure should be. I got 195/50/15's.. any recommendations?

i have changed my 206 tyre & sport rim to 15' and when i drive above 130km/h the car is shaking. is it possible because of the incompatible rim (but forced to fit in by the tyre shop?)

does anybody has a number of reliable tyre shop so i can ask em what actually happened?

Ethan said...

Incompatible rim but forced fit in? How la?
