Description
All other things being equal, widening the rear tire by 40mm while only adding 10mm to the front will increase understeer. HOWEVER, there's the bonus that I can chuck the spare wheel and tire -- all 25 pounds of it -- to the curb, and that weight comes off the back of the car. I figure that will help some to bring back the rear-end friskiness. If that still doesn't do the trick, I'll work some with aftermarket sway bars to restore things.
The stock wheel/tire was 41.4 pounds. My new front 18x8.5" Rota D with attached 225/40R18 is 44.6.
