NC Wheel Size, Offset Change To Improve Tyre Choice

[shindha]

Hi, at the moment I have 16" standard wheels on my NC 2.5 2009 2.0. I believe these are 6.5 X 16" ET55, with 205/50 R16 Federal 595 RS-R tyres.

The car has Miester R suspension with the standard height lowering that comes with the setup I believe 310mm at front and 320mm at the back.

I was thinking of the following options;

* 7 X 17" with 205/45/R17 tyres with ET55 all round
* 7 X 17" with 205/45/R17 tyres up front and 7.5 X 17 with 205/45/R17 or 215/40/R17 at the rear with ET55 all round

Would the 2nd combinations be a straight forward fit or will I need to roll the arches - which is something I don't want to do, in which case I would go for 7 X 17" and is the offset of ET55 ok when using 7inch wide wheels.

The wheels I would like to get are Team Dynamics Pro Race 1.2 in 17" hoping this would improve my choice of tyres.

Please feel free to make any suggestions or if you have any experience of using this sort of set up please share.

Same size front and back is a must, if you go 215 width stay at 45 depth, no need to change to 40 and your speedo will be more accurate than with the standard 205/45/17 size. Not sure about offsets but I'd imagine around 45/48 would be about right. No need to do anything at all to your arches at 215 width, you can possibly squeeze them in at 235 width with 17x8 alloys as long as it isn't lowered too much

My NC is also lowered on MeisterR suspension, with 7x17 ET40 wheels and standard-size tyres. No rubbing problems at all.

True, it should have come with 215/45 in the first place.

And yes +45/48 is probably ideal, it will not rub with 215s, possibly a little more too may be fine. I have 235/40 on 17x9 +49 it doesn't rub, though mine is only lowered an inch (2 deg F/ 1.5 deg R camber). I wouldn't recommend 235/40 due to difficulty of getting hold of tyres and the price, it doesn't over-tyre the car but I'll be moving to 17x8 and 215s once these are worn.
