Bigger/wider Tyres On C4 Vts

[rcandelori]

Hi from Sydney Australia!

 

Just wondering whether anyone could tell me if the C4 can accept wider tyres - say 215/50 or 225/50 versions.

 

I don't like after market rims and would like to keep the current 17 inch VTS rims.

 

Does changing the tyre type screw up the tyre pressure monitor?

 

Thanks!

Hi and welcome rcandelori,

 

Not too shure as the pressures will be slightly different, measure behind the wheel and tyre to see what gap you've got.

 

As for tyres 215/50/17 would be 10mm bigger diameter and your car would travel 31.45 mm more per revolution of your wheel

 

225/50/17 would be 20mm bigger diameter and your car would travel 62.8mm more per revolution of your wheel

 

you would be better off going for an 18" 205/45/18 which is about 5mm bigger on diameter and 15.4mm more on a revolution of your wheel

 

hope this helps and in my opinion i wouldnt bother going 10mm wider to 215,

ooops double post :blink:

Yeah I believe they should fit comfortably - trust me.... :angry:

 

I have 225/40/18 tyres with no problems, and a 30mm drop.

there you go rcandelori, sorted, just have to find out about tyre sensors

Also your speedo would over read slightly which means yould be driving slower than you think. :rolleyes:

if you read it it tells you 10mm bigger

 

205/50= 102.5mm side wall height, x2= 205mm side wall height

17" dia wheel convert to metric is 17 x 25.4= 431.8mm

 

431.8 + 205= 636.8mm total wheel diameter

 

215/50= 107.5mm side wall height, x2= 215mm side wall height

17" dia wheel convert to metric is 17 x 25.4= 431.8mm

 

431.8 + 215= 646.8mm total wheel diameter

 

new wheel and tyre = 215/50/17 = 646.8mm

original wheel and tyre = 205/50/17 = 636.8mm -

 

difference between the 2 is 10mm, new tyre and wheel is 10mm BIGGER :P

 

the 225/50/17 would be 10mm difference too, which i must admit i did calc wrong, but only 1 calc wrong not 2 like You!,

if you want to be like that smart arse :o :P :P :P :D

its like being back at school :D

 

I was as confused then as I am now...

Using the tyre size conversion software on one of the alloy wheel suppliers sites...

 

225/40x18 gives you the same rolling radius as the standard fitment 205/50x17

 

I'm just about to place an order for a set of 8x18" with the 225/40x18 wheels and tyres....which I have been told will fit...

 

We'll see... ;)

[rcandelori]

Thanks for all your replies. Much appreciated.

 

I would rather not get 18 inch wheels or lowered suspension as I prefer the appearance of the standard VTS 180 wheels and the suspension is already hard as it is without any lowering. (unless someone knows where I can get the C4 WRC concept 18 inch wheel + bodykit).

(unless someone knows where I can get the C4 WRC concept 18 inch wheel + bodykit).

there is a set very much like the WRC ones from Milia Miglia, click me!!!

 

The bodykit will follow next year according to Cituning (the people who do the Xsara WRC kit)
