Quick Tyre Question

[George16v]

If I have 16s with 195/45/16 tyres. Will I be able to fit 205/45/16 Tyres As this will give me a larger range to choose from!

Also will I loose or gain performnace from the wider tyres.

 

[stu8v]

You will loose performance

 

[Djw John]

But gain grip. And yes you can without a problem. Wont lose enough to notice it I reckon.

205 is NOT a problem, it is within the 2.5 % rolling diameter.

You will lose performance in terms of accelleration - i dont notice it.

You will gain performance in corners - i do notice it.

The car will also feel less precise due to bigger sidewall.

 

[Topper182]

You wont notice anything in loss you will find it a better drive probably like the 205s on the 182 compard to the 195s on the 172 ....

i find it quite the opposite.

surely the tyre wall is the same size, and as the profile is wider it will not flex as much?

(technically it is slightly bigger, but 45% of 195 and 45% of 205 is that tiny that the manufacturers say it is within tolerance of speedo / rolling resistance as far as I am aware)

[Topper182]

Exactly y0z2a my thoughts too...

 

[stu8v]

The tyrewall is a % of the tread width and as such 45% of 205 is greater than 45% of 195.

 

[Topper182]

How is the induction kit George did it fit ok ....

 

[Topper182]

205mm width by 45mm tyre wall and 16" diameter thats how i have always took tyre measurements to be has it changed ....

Do all 172/182/cups have the same width rims?

Do you know what width they are?

 

[y0z2a]

now off the top of my head, you know what, I just cant say LOL.

would you like me to measure them all tonight.

make your point... rather than asking questions?

/y0z

 

[George16v]

Well I think the 172s are 195. mk1s def. were as they had 15s

 

[badinvincible]

I thought this was a QUICK tyre question...?

 

[y0z2a]

it got complicated

:-(

/y0z

 

[Topper182]

7J Rim width i think ...

 

[Lagerlout]

This is quite a handy little tool if you looking at changing tyres etc.

Sorry meant 205mm by 45% by 16" is that not right ...
