What is the max difference in wheel circumference between front and rear that won't screw with the ABS and DSC?
Example, my stock sizes are:
F 225/45R17 Circ. 78.5 in.
R 245/40R17 Circ. 77.6 in.
Difference being 0.9 in.
I'm trying to get some BBS RS-GT's sized 19". BBS Germany says that I can either get 4 19x8.5 or Front 8.5 and Rear 10 (would have to seriously roll fenders). So I decide on 4- 8.5 rims, now tire sizes...
I don't want to go with 235/35R19 all around because I don't want to lose any width in the back compared to stock.
Here's the sizes BBS recommends:
F 225/40R19 Circ. 82.0 in.
R 255/35R19 Circ. 81.8 in.
Difference being 0.2 in.
I would prefer these sizes:
F 235/35R19 Circ. 80.0 in.
R 255/35R19 Circ. 81.8 in.
Difference being 1.8 in.
So does anybody know if a 1.8 in. difference will mess with the ABS+DSC?
By the way, I'm getting Michelin PS2's (http://www.michelinman.com/assets/pdfs/doc_pilotsportps2.pdf)
...and I used this Tire Calculator (http://www.miata.net/garage/tirecalc.html)
TIA
