Hi guys

Just wondering if someone could tell me what size tyre fits on the EL GT copies (17x8 i believe).

Thanks

The copies are 17x8" yes.
Any 235/45/17 tyre will fit.
if you want to go wider tyres you should be able to get up to 255, onto the 8" rim.

Standard issue would be 235/45/17. You can also go 245/40/17 or 255/40/17, though you get a little bit more flex in the wider sizes. The 235's have been standard on 17x8" rims since the AU, and with these there should be no need to recalibrate the speedo or anything.

Here is a site that will help you work out the best tyre, closest to fit without upsetting your speedo to much.

how would the tyre width upset the speedo

It's overall rolling diameter of the tyre that affects the speedo. Width, tyre size and profile all affect the speedo...

XRQTOR · 04-19-2004, 05:49

yea i can understand high profile but how the hell does width affect speed. If a tyre is 1 inch wide rolls down the street at 20km's how would a 20 inch wide tyre roll qiker given the same conditions as the first.

I aint too sure, width hasnt affected my car too much. I have the ELGT replicas and (strangely) i'm on 225/45/R17 tyres. I checked the speedo calc test and it said width doesnt do much in terms of speedo difference

but i'm not too sure. Thered be someone here who knows more than me :p
