Title: 225/35 or 235/35?
Post by: L555BAT on 19 February 2008, 10:20

Looking at getting a set of 19"x8" wheels, but unsure as to correct tyre size.  Should it be 235/35/19 or 225/35/19?
Any ideas?
Cheers.

225 35 19" to keep the rolling radius correct and to prevent having any problems if you lower your car!

2nd that. 

The standard tyre diameter on a 225/40/18 is 637mm
Upgrade on a 235/35/19 Diameter is 647mm
Upgrade on a 225/35/19 Diameter is 640mm

You can use a 235 but its not ideal.

I've been advised that 235/35/19 are the correct tyres due to the loading of the tyre....
225/35/19 are usually 88Y and 235/35/19 are 91Y.
OEM / Standard tyres 225/40/18 are 92Y for the GTI not 225/40/18 88Y which some tyre fitters will try to sell you..

The difference in rolling diameter is less than 2%, so i wouldn't worry about it. It just makes the speedo a little less inaccurate.

What offset will the wheels be? That will also effect whether they are likely to rub or not.

Correct off set would be OEM.... ET51/ET54
I'm getting ET50.
Some with ET45 have rubbing issues.

With 235s on 50 offset, should look sweet  :cool:
should not have clearance issues unless you go too low.

NEG... do you have any pic's of your car with the 19 BBS CH's. Have you had to get it lowered for the right look....

Hi... The car in the picture looks smart. Have you lowered the car, if so are they just springs or spring/shocks.
The 235/35/19 tyre looks better than the 225/35/19 as seen on some other cars. It think the 225/35/19 must be stretched a bit to fill the 8" rim.
The 235/35/19 tyre wall seems more box like/straight to the rim.... if you know what a mean.

I think the tyre's are fine, no stretching and look just right.

Running Koni FSD's and H&R springs for that ride, its spot on - a little firmer but just about right.
