What ET on 17

[ruf_ect]

I am thinking of picking up a set of 17" rims for my 172 Mk2 on a trip to the Nürburgring next week. Ill be driving my 16v so I cant trial fit them...

What ET should I get, I am geting 17x7 whith 205/40-17 tires. My car has 48ET, but I read the Cup has 38,5ET.

Will 35ET fit? I am putting on some H&R springs (30mm) soon.

et37/38 is best

 

[geordiepaul]

I would have to say ET40 would be best and go for 195/40R17 tyres

If only to disagree

 

[geordiepaul]

Oh and according to speedline you will get rubbing on ET35 once it has been lowered more than 20mm

 

[McBunny]

we can only really tell by fitting them lol but the alloy manufacturers i have spoken too all said 37

 

[RobFenn]

Confused again Mike lol

Surely ET35 would be best as the wheel is sticking out further?

 

[ruf_ect]

I have never heard of 195/40R17 tires...

 

[McBunny]

your getting too close to the arch then

 

[geordiepaul]

Yes the wheel is sticking out futher but that nearly 15mm out from the offset that the car was designed for!!! The closer you stick to 48.5 the better.

195s do exists and only Pirelli make them they are the same width os standard so no problems at all!!

I have been all over the Pirelli site, but could not find the 195/40R17

wouldnt go too low with the offset, stick them out too far and youll increase the loading on the steering so itll dart all over the shop on poor surfaces, over kurbs itll kickback far more etc etc and generally wont feel very nice on fast corners.

The difference in tyre radius between 195 and 205 is 4 mm thats 8mm in diameter, quite a bit. 195 are the closer match to the standard wheel+tyre diameter, but they may look (handle) odd on alloys that have a depth of 7.5 rather than 7.

 

[geordiepaul]

They wont fit on a 7.5" inch rim!

 

[badley]

there you are then

 

[geordiepaul]

But then I wouldnt reccomend putting a 7.5" rim on a 172 in the first place.

 

[Fred@BTM]

you need 17x7 ET37 for a MK2 172

Bang on ET37 is ideal, or ET36 would be fine as well, but Ive never seen this fitment. Dont go ET38+ on 7"+ wide wheels unless you fancy taking out the inner arch liners like I had to! And dont go below ET35 or itll rub on the outside arch.
