Hi guys,
Didnt think i'd be also asking a tyre size qs, but here goes,..
I shall be receiving my Hartge Classic 2 replica wheels soon. I have now 245X40X18 which translates best to 285X25X20 for the back (please correct me if i'm wrong) ,.. but here are the questions:
Back Wheels is 9.5J and front wheels is 8.5J
1. Will 285 fit on a 9.5J wheel
2. And what size tyre shall i take for the front? Remember it is 8.5J
looking forward to your answers...
Ronald

285/25/20 is the correctly calculated transformation size and will fit a 9.5" rim perfectly fine.
The fronts should be 245/30/20 in line with the rears.

Yes - i just checked. U r exactly right. there is actually very little other choice. 255x30x20 give a bigger difference in comparison with the rear 285's.
so i guess 245/30/20 it is !

the sizes you mentioned are correct.
i guess you are aware that upgrading to 20" will cost performance esp. acceleration, i had 18" before and now got the m166 19" m5 size, even the alloys are pretty lightweight i can feel that the car got slower.
it's even more difference comparing the 17" winter tires with the 19" summer tires, i once stopped 100-200 km/h, it made more than THREE seconds difference. :thumbsdown:
you said you bought replicas and i would wonder if they are lightweight in any means, so i do not want to drag you away from getting them but let you know the experience i made before you buy them
btw they look great
