From 16570R14 to 19565R15 wheels on Ibiza MK4 1.4TDI

[shivy]

Hello,

Today replaced the old/original wheels with the Audi A3 19565R15.

Yes they are bigger, but... they do not rub on the plastic covers, even if full lock I have 1 finger clearance (1cm).

Car is a bit higher so better for pot holes and bumps

However I would like your suggestions about the following points:

1) the centre bore is the same diameter but it does not stick out as the old/original rims, all the way through the old ones, but only about 1cm or less on the new ones (see pictures) But the ET is the same as Ibiza.

Does this mean the new wheels are not well secured ?

2) the acceleration has gone, does it mean they are too heavy for the car ?

But many ibizas have 17" on them and no problem.

Will braking also be affected ?

3) will the bearings suffer and die prematurely ?

4) less fuel efficiency with big wheels ? Same time the acceleration peaks are gone, so no extra fuel injected for that ?

 

 

 

 

 

 

 

Thank you

The tyres are too big , going from a 14 to 15 you should have dropped the profile more ie 195 50 15 , you have essential changed the gearing on the car which is where your acceleration has gone , your speedo will also be reading incorrectly now

 

 

The centres look fine

 

Heavier wheels and tyres will put more load on the bearings and will use more fuel but shouldnt effect braking

 

 

You can put all the data in here

Hi

Looks really messy if i'm honest, why have you done this and more importantly looking at the images how many turns on the threads do the wheel nuts have on the studs?....
