That's a great pic Greg--thanks!
After using various online tire calculators, the taller tires I want will have the tire .2" closer to the suspension on the inside and .2" closer to the fenders on the outside. Based on my measurements that should be no problem.
The tire will be .625" taller (5/8") and also have 5/8" clearance between the top of the tire and the bottom of the lower spring perch on the front. Again I don't think this will be a problem.
Now what I'm wondering is what (if any) probs could I have with ABS/VSC/traction control systems? I understand it may take longer to stop with the taller and slightly heavier tires, but will it turn on any dash lights or render these systems inoperable?
Searching online, I've read that factory ECU's can tolerate anywhere from a 3% to 15% variance in tire diameter. But I can't find anything specific about the xB. Are there any knowledgeable persons or Toyota/Scion techs hanging out on these boards that can provide more insight on this?
