Rims and Tires

[Ldub]

I'll add one thing...(just to stay ahead of Bart & Skippy)

With larger wheels & tires (33-12.50x20" or 285/75x16", both pretty close to 33" dia) it's not unusual for the TOD to "light up" under hard acceleration, even under grippy traction conditions.
Dunno exactly what causes it to freak, other than the dia being WAY outta spec, but I no longer worry much about it...
